IN THE NEWS
Call for poultry vaccination
According to international animal and human health experts gathered for emergency talks at the Food and Agriculture Organization (FAO), a targetted vaccination campaign for poultry at risk of being infected by the highly pathogenic avian influenza virus may be required in heavily affected nations to control the epidemic from spreading. Issuing a series of recommendations after two days of discussions, the group of experts, which included representatives from the World Animal Health Organization and the World Health Organization (WHO), expressed that vaccinating animals is one method, along with culling and other priority measures, to contain the spread of the virus. |
Seafood exports from India
India is one of the leading exporters of marine products and occupied the 16th place among the top exporting countries during 2001, as per statistics published by the Food and Agriculture Organization. The Indian government has initiated several steps to raise exports, including:
The government has also issued guidelines for operation of Indian-owned deep sea fishing vessels in the Indian Executive Economic Zone (EEZ). These guidelines allow import of deep sea fishing vessels by Indian firms for operation in the Indian EEZ to promote production mainly directed at exports. |
Upgrading meat sector in Korea
In the Republic of Korea, the government has presented the first draft of its plan for the livestock industry, as part of the countrys agreement to comply with the World Trade Organizations Doha development agenda. The key focus of this plan is increased commercialization of the industry, upgrading hygiene and safety standards, improved effectiveness of animal epidemic prevention steps and the development of eco-friendly products. It is planned that by 2013, 20,000 specialist livestock producers will produce 85 per cent of livestock. |
Transatlantic database on pathogens launched
The worlds largest on-line database of information on how pathogenic bacteria respond to different environmental conditions in food has been set up. Scientists with the United States Department of Agricultures Agricultural Research Service (ARS) and the United Kingdoms Institute of Food Research (IFR) have jointly established ComBase. The database is designed to help facilitate easier risk assessments and model development. It combines two software packages ARS Pathogen Modelling Programme software, a research and instructional tool to estimate the effects of multiple variables on growth, inactivation or survival of foodborne pathogens, and the Food MicroModel jointly produced by IFR and the Foods Standards Agency, which is used to describe bacterial responses to food environments. At present, the new database contains about 25,000 growth and survival data records.Microbiologists in academia, government and industry can submit data to ComBase, thereby eliminating unnecessary repetition of experiments among laboratories, improving models and standardizing data sources. |
Indian food exports to comply with new legislations
Exporters of food and animal feed will henceforth have to comply with a new legislation in the United States. The Public Health Security and Bioterrorism Preparedness and Response Act, 2002 came into effect from 12 December 2003. Making a presentation of the new law, the United States Agricultural Attache for India, Bangladesh and Sri Lanka said that this was not a protectionist measure. He assured that the law would be applied equally to both domestic and imported products. The new set of regulation will include registration of food facilities, prior notice of imports by importers, maintenance of records of imports and administrative detention. |
China allows GM products
Chinas Ministry of Agriculture has awarded its first batch of safety certificates for genetically modified (GM) crops used for processing purposes in the country. This development is the result of a series of environment and food safety tests on seven GM crop strains from Monsanto Co., the United States. This first-ever approval for biotech products has broken down a key trade barrier between China and the United States. During the first five months of the current marketing year, soya bean sales to China reached 8.3 million tonnes, over a third of the total soya bean sales to all of the United States export destinations. According to the Ministry, of the seven applications, five were granted safety certificates Roundup Ready soya beans, a version of Roundup Ready corn, YieldGard Corn Borer, Bollgard cotton and Roundup Ready cotton. The certificates are valid for 3-5 years. The other two, NK603 maize and Mon863 maize, were rejected. Processing is underway for another 11 applications from the United States-based DuPont and Dow AgroSciences, Bayer of Germany and Syngenta, Switzerland for GM rapeseed and maize. Seen by some as a strategy to control its import trade, China previously required traders to get temporary safety certificates, usually valid for a few months, if they had to import biotech grains.

Russia lifts import duties on soya beans and corn
According to the American Soybean Association, the Russian government is not imposing import duties on soya beans, corn and fishmeal for nine months, starting 26 January 2004. The United States Department of Agriculture has reported that as feedstuff demand grows along with the livestock sector, this action will open up export opportunities for the nations agricultural products. The government of Russia has revoked the 5 per cent import duty on soya beans, corn and fishmeal in order to boost imports of feedstuffs crucial for the development of Russias poultry and livestock industries. |
China to combat insecticide residues on food
In China, the Deputy Director of the Market Circulation and Adjustment Department, Ministry of Commerce (MOC), has stated that though overall food safety in the country is good, problems such as insecticide residues on fruit and vegetables, and fake products persist in a few areas. In this regard, MOC is working with other ministries to establish a monitoring system. A network would collect and analyse data on food safety in slaughter houses, wholesale and retail markets. China has promulgated over 200 laws, regulations or standards on food safety at national or regional levels, including two sets of new criteria on the wholesale and retail market for agricultural and related products. The government has expressed that a further 500 measures on food processing and distribution would be passed over the next five years. The latest initiative aims to highlight companies that maintain good records on food safety and hygiene, and to publicize on the Internet the companies that do not meet the criteria. |
Indian processed food exports
Indian food exports stand at about US$6 billion as against the worlds total of US$700 billion. Total food production in India is expected to double in the next ten years. According to latest official statistics, India exported processed fruits and vegetables worth around US$100 million in recent years. Horticulture production is about 120 million tonnes. There is an increasing demand, especially in the Middle East countries, for products such as pickles, chutneys, fruit pulps, canned vegetables and fruits, concentrated pulps and juices, dehydrated vegetables, and frozen fruits and vegetables. |
New system to ensure food safety in Beijing
Health supervisory authorities in Beijing, China, will introduce a selective investigation system among catering companies in a bid to cut down on the increasing number of poisoning scares in the industry. Forty-two cases of food poisoning were reported in Beijing during 2003, involving 751 people. More than 85 per cent of these cases were caused by unhygienic practices in food processing. |
Food park scheme in India
The Ministry of Food Processing in India recently announced a new Food Park scheme as one of several measures to avoid wastage in the food processing industry. Each of the proposed park, with a basic grant of about US$725,000, would have a minimum of 20 food and processing units. New small and medium enterprises, which find it difficult to make capital investment, can make use of the facilities in the food park. Even the food packaging industry can avail itself of the scheme or function independently, but use the 25 per cent subsidy. Well-built infrastructure for vegetables and fruits, cold storage for milk processing, fish and meat products, and warehousing for rice and flour mills are some features of the Food Park scheme. Twenty such parks have already been identified. |
SAFETY/QUALITY CONTROL
Rapid ID system
In Australia, CSIRO Plant Industry has developed a simple high-throughput testing system which accurately identifies wheat and barley varieties. The new system tests leaf or grain samples using a panel of DNA markers. Each marker gives a yes or no result. The pattern of results generates an individual bar code for each strain. Designed to be simple and accurate, even for very closely related varieties, the system can easily process hundred of samples in a day, outperforming previous tests in accuracy and throughput. The wheat variety ID test is licensed by Agrifood Technology. Website: www.csiro.au |

X-ray system to detect contamination
Applied Sorting Technologies, Australia, has designed and developed XR3000J X-ray contaminant detection system for inspecting products in glass jars. Based on the companys successful X-ray contaminant detection system, the new system can also be used to inspect block cheese and a variety of packaged foods. XR3000J can be installed immediately after the jar capping machine and directly on to the main jar conveyor line. It detects and removes any jars suspected of containing foreign bodies. Contaminants that can be detected include non-metallic fragments such as pieces of glass or stone below 3 mm in size, pieces of metal too small to be detected by conventional metal detectors and a variety of plastics and special purpose rubbers. In addition, this system can detect, at production sites, jars with improperly fitting lids and underfilled jars. |
On-line detection method
Food Radar Systems AB, Sweden, has developed technology to detect most kinds of foreign bodies in foods. This breakthrough in on-line quality control of food products can detect contaminants such as glass, wood, plastic, bone, shells, cartilage, rubber, seed and metal. Foreign substances are detected in embedding material by transmitting low-power microwaves through the material. The transmitted microwaves are detected in such a way that the damping and run-time of the microwaves are available as measurement data. The near-field microwave radar can detect objects measuring 2-3 mm. |
UV disinfection
Haslington Cheese, the United Kingdom, has installed two ultraviolet (UV) disinfection tunnels to ensure all packaging surrounding cheese entering a high-care area is free of microbial contamination. The UV tunnels disinfect packed blocks of cheese before they pass into the high-care production area of the plant. According to Dr. Aidan Wilson, Technical Director, UV was chosen to keep the high-care area dry, thus ruling out the usage of chemical sprays or dips. Satisfactory experience with a duct-mounted UV unit set up in the air-conditioning system was another reason. |
Metal detector for mushrooms
The worlds largest fully integrated, single-site mushroom farm is located in the United States. Creekside Mushrooms site includes a 241 km labyrinth of abandoned limestone tunnels nestled 300 feet underneath the hills of southern Pennsylvania where 11.3 million kilogrammes of fresh mushrooms, including speciality mushrooms such as portabellas, shiitakes, oysters and enoki are grown every year and 2,036 acres above ground. The company developed a comprehensive food safety and HACCP programme soon after opening in 1994. The programme is designed to prevent any chemical, microbiological or physical contamination from occurring while growing, harvesting, packaging or shipping the products. Creekside has also installed metal detectors to further ensure safety. Though mushrooms are harvested by hand and there is minimal exposure to metals, contamination could potentially occur when the mushrooms are sliced. Two Eriez E-Z Tec metal detectors were installed for the fresh cut mushroom packaging lines. These units are designed to detect even the most minute ferrous, non-ferrous and stainless steel metals. Creekside has added three more E-Z Tec metal detectors for its retail packaging lines. To ensure accuracy, each detector and rejection device is checked and its operation verified prior to start-up of the lines. Contact: Mr. Jeff Kaveney, United States of America.

INGREDIENTS
New technology reduces need for toxicity test
Researchers at DSM Food Specialities have come up with the Markergene-free expression system, which effectively makes it possible to insert any desired gene in an expression cassette, making efficient production feasible. DSM worked on the food-grade micro-organism Aspergillus niger that is used as a basis in the production of several food enzymes, including glucose oxidase, pectinase and glucoamylase. According to Dr. Gert Groot, DSM, the Markergene-free expression system for A. niger strains and production processes means that new enzymes can be produced without having any genetic markers in the production process. As a result, food manufacturers and other enzyme users can test and develop new enzyme-based products without the need for additional costly and time-consuming toxicity tests. |
Healthier soya oil
Researchers at ARS Soya Bean and Nitrogen Fixation Research Laboratory, the United States, have developed new germplasm using traditional breeding methods. Oil from soya beans bred from this line of germplasm could one day compete with olive oils front-runner position as highest in heart-healthy levels of monounsaturated fats. Oil from the germplasm line has less than half the highly unstable polyunsaturated fatty acids present in commercial soya bean oils. The germplasm will be a useful resource for breeding soya bean varieties suitable for different growing regions. |
Technology helps realize innovative products

The new procedures improve processing efficiency, consistency, moisture retention and flavour of poultry, meat and seafood applications. |
New antioxidant powerhouse
An international team of scientists have developed a new family to antioxidants that are up to 100 times more effective than vitamin E. Antioxidants are molecules that counteract the damaging effects of oxygen in tissues and other materials. In vitro tests on cholesterol molecules demonstrated that the new antioxidants protected LDL molecules from oxidation, an indicator to its potential use in the fight against the onset of coronary artery disease. |
New yeast products
Overseals Yesto-Seal range has been developed to either replace or work synergistically with yeast extracts. Through careful selection of inactive dried yeast blended with natural flavours, Yesto-Seal offers cost-effective yeast blends that provide excellent flavour and also overcome many of the processing issues associated with yeast extracts. The new range is targetted for use to enhance savoury flavours in snacks, seasonings, soups and sauces. |
Edible adhesives
In the United States, researchers at ARS National Centre for Agricultural Utilization have developed a sugar-based edible adhesive for a beverage packing company. The company needed a strong, flavourless, fast-curing, food-grade adhesive that could bond drinking straws to a special holder that is lowered into beverage cans, cartons and bottles before they are filled and sealed. At this point, the adhesive should dissolve or else the straws remain fixed to the holders instead of rising freely when the containers are opened. |
STANDARDS/REGULATIONS
Integrated food law
The Indian government is contemplating on an integrated food law to curtail and specify the residue limit for pesticides in food products. According to the Minister for Health and Family Welfare, the Ministry had prescribed MRLs for 71 pesticides, raising the total number of approved pesticides to 181. At present, new pesticides are not being registered and MRLs would have to be stringently calculated before approval. The government is also considering amending the Prevention of Food Administration Act (1954) and PFA Rule (1955) to make them more stringent. The government is advocating integrated pest management, including need-based and judicious use of pesticides, use of bio-pesticides and banning or phasing out of certain pesticides. Indian Dairyman, January 2004 |
India curbs import of vegetables and fruits
The Indian government has prohibited import of several seeds, fruits and vegetables from Africa, the Caribbean, South America and Sri Lanka, and forest plant trees from the United States because of the destructive pests and diseases carried by them. Plant material imports have been restricted to commercially significant crops like banana, potato, citrus fruits, cocoa, coffee, tobacco, cotton and coconut to official agencies only. Stringent new quarantine rules as well as sanitary and phytosanitary (SPS) certification norms have been stipulated for flowers and products like rice, wheat, grapes, apples, pears, citrus fruits, peas, coffee, chick peas, cotton and tobacco leaves. In addition, governments in exporting counties have to certify that their shipments do not contain pests and weeds not present in India. |
Russia plans import regulation
The Russian Deputy Prime Minister declared that, taking into account the situation on different markets for agricultural products, the work on improving the policy on customs tariffs will be continued to protect the nations agricultural producers from unfair competition. The proposed measures include regulating the import of sugar and meat, and increasing custom duty rates for meat imports outside quotas and to ban poultry imports outside quotas. A customs duty rate for sugar, which will automatically adjust depending on world sugar prices, is to be introduced for regulating the importation of raw sugar. In general, major plans of the Agriculture Ministry for 2004 include:

MEAT/POULTRY PROCESSING
Measuring meat and fat composition in pork
A researcher at the United States Agricultural Research Service has developed technology to efficiently indicate how much lean meat or fat is present in a commercial cut. In lab-scale trials, dual X-ray absorptiometry (DXA) has accurately shown the composition of pork carcasses. This non-invasive and quick procedure utilizes X-rays of differing energy levels to scan for soft tissue of varying densities. The DXA instruments scanned carcass cross-sections at a speed of 0.0768 m/s, compared with the processing chain speed of 0.166 m/s. |
Thawing meat and seafood
QuickThaw Technologies Pty. Ltd., Australia, offers an alternative to microwave and water tempering of meat and other foods. The Morep QuickThaw system is a specially designed wind tunnel using super high-speed turbine fans to move warm air over the surface of materials in a controlled pattern and at velocities not possible in a conventional cooler. The heat transfer process is monitored by a series of probes placed in and around the material. The probes feed back real-time temperatures to a PLC, which analyses the data, calculates the rate of heat rise in the material and changes the conditions in the sealed chamber adding more or less heat or cold, adjusting air speed, etc. to achieve the defined goal. QuickThaw also enables the processor to define the limits of acceptable temperature rise. Once the defined core temperature is reached, QuickThaw automatically converts from an active thawing mode to passive storage mode, where the air speed and temperature are reduced to a point that heat transfer is suspended, enabling equilibration while holding the material at the proper process temperature indefinitely. Once the process ends, the entire thermal history of the product, from the time it was loaded into the chamber until it is removed, can be downloaded to a computer for HACCP or quality assurance documentation.

BEVERAGES
Tamarind juice concentrate
Researchers at the Central Food Technological Research Institute (CFTRI), India, has developed a process to manufacture a concentrate form of tamarind juice. Tamarind is used as a condiment in several culinary preparations. The new process involves extracting all the water solubles from the fruit pulp by boiling with water under optimum conditions, concentration of the clarified extract, under vacuum, to about 65-70 per cent solids and packing in suitable containers. The final product becomes quite viscous and sets to a jam-like consistency on cooling. Tamarind seeds available as a by-product could be converted into tamarind kernel powder, which is used for sizing in the textile industry. |
Banana juice
An agro-food research assistant at the Pech-Rouge INRA Centre, France, has succeeded in manufacturing pure banana juice. Flash Detente technology comprises heating fruits to 90-95C and then subjecting them abruptly to extreme vacuum. This breaks down plant cells, thus facilitating juice recovery. The polyvalent process can also be applied to other fruits. Pure banana juice obtained (100 per cent banana without added water or sugar) presents all the characteristics of flavour and colour of fresh bananas, as well as their nutritional qualities. |
PACKAGING
Automated labelling and tracking solution
Peacock Bros., Australia, has developed a solution for a customer who needed a processing and packaging system to identify individual palletized packaged products on a conveyor system and automatically apply two bar code shipping labels on opposite sides of each pallet.

Probiotic bacteria: A boon
Researchers at the University of California, the United States, report that the digestive system can derive the same benefit with the presence of DNA from probiotic bacteria as when live bacteria are present. Mr. Eyal Raz and colleagues studied the effect of probiotic bacteria on mice with colitis, a condition similar to inflammatory bowel disease in humans. They found that the bacteria were just as effective when inactivated with gamma radiation as when live cultures were used. A similar scenario was observed when mice were treated with a synthetic DNA molecule known as an immunostimulatory oligonucleotide, which mimics the effect of bacteria on the immune system. This new discovery may allow the health benefits of probiotic bacteria to be incorporated into a range of different types of foods, or even pills and injections. Live bacteria are generally restricted to products such as dairy foods, since cooking or heating the culture kills them. According to Mr. Raz, live probiotics are not the best way to deliver the DNA. Website: www.nature.com |
Seeing the UV light
Ultraviolet (UV) rays inactivate E. coli bacteria by degrading their cell walls and DNA. Researchers have further uncovered that in direct contrast to pasteurization, the sensory quality of food products is not affected by irradiation. Also, inactivation of the bacteria lasted for the entire shelf-life of the product. Heat pasteurization often affects both the flavour and consistency of food. Scientists working on the project hope that this represents a breakthrough in the fight against foodborne pathogens. |
Gene chip for the food industry
BioMerieux sa, France, has developed a version of gene chips, invented by the United States-based Affymetrix, aimed at food producers, processors and retailers who want to check the source of products or monitor food safety. FoodExpert-ID is sensitive enough to detect the difference between tuna caught in drift-nets, which also tend to kill dolphins, and alba tuna, the more expensive fish that is caught using a more eco-friendly method. The new chip can even differentiate between duck and goose meat. Implications for the food industry, which is now more responsive to demands for ethical and hygienic food, are enormous. |
