Functional foods are fine, but safety counts

by Hoang Ha

HCM CITY — Functional foods including increasingly popular food supplements can help fight serious diseases in both developed and developing countries, experts said at a two-day conference that ended in HCM City yesterday.

Food scientists, however, also stressed the need to ensure that the ingredients and processes applied meet "global sound scientific standards" for food safety.

Dr Mary Schmidl, adjunct professor of the International Union of Food Science and Technology (IUFoST) Scientific Council Chair, mentioned the need for making smaller portions of all foods, including functional foods.

She said long term safety studies and ‘in market surveillance" were necessary, especially for new highly enriched or fortified foods.

While functional foods can help tackle food safety, hunger and obesity, she said companies making them need to have sound scientific evidence to back up their claims about benefits provided by their products.

"False claims give false hopes to desperate people and, in the worst case, delay necessary treatment," she said. She said functional foods must not distract people from adopting a healthy diet.

The most recent trend in food innovation and development is the use of novel or traditional functional ingredients, said Ser-Low Wai Ming, president of Singapore's Institute of Food Science & Technology (SIFST), a professional society of food scientists, food technologists, chemists, biochemists, microbiologists, engineers, educators and other technical personnel.

Safety innovations

Safe, quality and healthy food is the requirement of the day, said Prakash, director of India's Central Food Technological Research Institute.

"Hence, agro-based raw materials need to be added to nutrition," he said.

This can be achieved through empowering rural and semi urban spheres with adaptable food technologies through micro, tiny, cottage and women entrepreneurship, he said.

The driving force of this process would be "cascading small, medium, large and global food industries," he added.

Prakash said the farming system, agro-industry and technologies of identification, verification, refinement and transfer are requirements for enhancing food safety, as well as nutritional and food security.

Besides, the food safety system must have four key attributes to achieve its objectives: prevention, accountability, integration in the chain, and risk assessment, he said.

To deliver safe food with zero contamination of pesticides, zero contamination of heavy metals, absence of toxins and no pathogens is not an easy task, Prakash said.

Do Thi Lan Nhi, training manager at the Viet Nam Administration of Food Science and Technology (VAFoST) said there were food safety concerns about many popular food items in the country, including the nation's most popular dish, Pho (rice noodle soup with beef or chicken), fish sauce and coffee.

The ingredients used in preparing these dishes by small, family based businesses were not easy to keep track of, she said. The chili sauce made by family-run workshop, for instance, carried no labels and could use hazardous biological and chemical substances, she said.

The conference, billed as the "first international symposium in food science and the technology" was co-organised by the IUFoST and the VAFoST. — VNS

Food safety, hygiene-top priority

Food safety, hygiene-top priority

Vietnam has paid a lot of attention to food safety and hygiene as the National Assembly has passed a law on the issue, which will come into effect in July 2011.

The Ministry of Agriculture and Rural Development (MARD) held a forum of donors’ on food safety in Hanoi on December 1. The head of its International Cooperation Department, Luong The Phiet, reaffirmed the important role played by farm produce in the national economy and the need to improve the quality of farm produce to improve people’s standard of living.

Andrew Smith, a development officer at the Canadian embassy in Vietnam , said that once food safety is ensured, Vietnamese farm produce will have more opportunities to export as well as contribute to improving the health of consumers.

The forum, co-sponsored by the International Support Group, is a venue for international donors and Vietnamese agencies to exchange information and experience in food safety and work out ways to effectively use international aid in this field.

The forum was concluded with the debut of the website www.thucphamantoanviet.vn which provides information on the quality of farm produce.

The event was part of a project on increasing the quality of food and agricultural products, worth 16 million CAD and funded by the Canadian International Development Agency. The five-year project will run until 2013 to improve quality and increase access to overseas markets for Vietnamese farm produce./.

GMcrops can ensure food safety: scientists

Plants like corn and soybeans with modified genes are pest-resistant and have a higher yield, but have no negative impact on human health or the environment.

Prof Tran Thi Cuc Hoa of Cuu Long Delta Rice Research Institute said the institute has transferred selected pest-resistant genes to several varieties of soybeans.

The results showed that the transgenic lines had significantly higher pest resistance compared with non-genetically modified lines.

"The soybean is an important food plant in Vietnam , planted on 20,000ha of land, but with a low yield because of pests and plant health," she said. "The use of genetically modified [GM] soybean varieties is a feasible solution to increase production."

In the Philippines , the use of GM strains has been used in corn, the number-two crop in the country, following rice.

GM corn has had high yields across the seasons, generating positive differences of 4-34 percent over the original hybrid corn.

This resulted in an income increase for farmers from 3 percent to 75 percent during the wet season, and 1 per cent to 75 percent during the dry season, said Dr Reynaldo V Ebora of the University of the Philippines Los Banos College .

Ebora, director of the university's National Institute of Molecular Biology and Biotechnology, said GM corn has generated a higher caloric content than conventional corn.

Another expert at the workshop, Dr Nguyen Quoc Binh, deputy director of HCM City Biotechnology Centre, said pesticide manufacturing and spraying are not necessary to protect GM crops.

Because GM plants are pest-resistant and not harmful to human health, there is no need to use pesticides.

Binh said findings show that worm-resistant transgenic plants have no negative effect on the environment, thanks to the use of Bt (Bacillus Thuringiensis) toxins that are produced within the plant and kill pests that attack the plants.

Ebora of the University of the Philippines said his observations of six years show that genetically-modified Bt corn in the Phillipines planted in fields does not adversely affect other varieties of corn crops in the fields.

Dr Duong Hoa Xo, director of the HCM City Biotechnology Centre, noted that the adoption of GM plants had occurred 15 years ago by some countries, and by last year, there were 124 million ha of GM crops in 25 countries, with 45 million farmer households involved.

Xo said the workshop showed that GM plants are safe and could enhance the socio-economic development of the country.

The workshop will also be held in Hanoi on September 30 and Vinh Phuc on October 1. It is coorganised by the Ministry of Agriculture and Rural Development and the US Embassy in Vietnam , which also sponsors the event.

Le Thanh An, consul general of the US General Consulate in HCM City, said the workshop is an attempt to bring scientists, farmers and policymakers together to improve Vietnam's economic development, poverty reduction and environmental protection.

In the context of climate change, including changes like drought, acid soil, low or high temperatures and pests, GM crops will be the key to food safety, according to Prof Bui Chi Buu of the Southern Agricultural Science Institute./.

GMOs can ensure food safety: scientists

HCM CITY — Genetically modified crops will play an important role in ensuring food security and sustainable development, according to experts at a biotechnology workshop held in HCM City yesterday.
