In recent years, some countries are plagued by food safety problems caused by major animal diseases such as mad cow disease and bird flu, and food safety is facing severe challenges. Therefore, some experts and scholars have called for the protection of the ecological environment and the sustainable development of animal husbandry in the development of modern animal husbandry. Only in this way can we provide a large number of animal foods of high quality and safety for humans. In some developed countries, agriculture has adopted intensive and industrialized production methods and productivity has been greatly improved. The characteristics of intensive and industrialized agriculture are "high input, high output, and high efficiency." However, this mode of production also lays a hidden danger for the healthy and sustainable development of agriculture. More and more people believe that the practice of violating natural laws and blindly pursuing maximum profits has affected the sustainable development of agriculture. Long before the large-scale food safety crisis such as mad cow disease, some experts thought that intensive farming had some drawbacks, such as serious pollution, overexploitation of water and soil resources, and the impact of a single operation on species diversity. First of all, contrary to the laws of nature, artificially or excessively improving the productivity by means of improving the formula of feeding and disrupting the natural growth of animals can not but be said to be an important cause of the large-scale spread of livestock and poultry. Some livestock originally live on herbivores, but the industrial production process is used to keep animals. This has led directly to the simplification and variation of domestic animal species. For example, Mad Cow Disease (BSE) is caused by the processing of meat and bone meal from dead bodies of dead sheep as a protein supplement to feed cattle, a ruminant that originally grazing but does not eat meat. Because of the disease's pathogen, prions are particularly resistant to high temperatures, meat and bone meal processing temperature can not kill it, prion through the concentrated feed into the food chain. The cow’s long-term and constant exposure to prions resulted in the cow's body adapting and crossed the “seed barrier†of the mutton and infected the cow, resulting in mad cow disease. Second, the use of highly intensive production methods has shortened the feeding period of livestock and poultry. The density of animals in the farms is too high. There are thousands of chickens, even hundreds of thousands, and antibiotics and other preventive drugs are used extensively. People use electrified and computerized means to control the growth environment of livestock, such as temperature and humidity. However, infectious diseases are highly contagious in highly intensive breeding sheds. Hundreds of heads of livestock live in a confined space. Once a plague occurs, the possibility of contagion through air, feces, and water is tens of times higher than that of traditional natural grazing. Under this condition of feeding and management, animals lost their natural state of activity and reduced their resistance to disease. In addition, if the drug is used without restriction, the animal's resistance to the disease will become worse and worse, and the virus mutation will accelerate. Once a problem occurs in a feeding section or a highly contagious disease such as mad cow disease, foot-and-mouth disease, bird flu, etc., it is not only tens of thousands of livestock, but also a food safety crisis that threatens human life. Health and safety. Today, more and more countries are realizing that the production of agriculture and food is only concerned with efficiency and efficiency. It is not enough. It must also consider the impact of production on resources, the environment and consumer safety. First, according to the current popular organic animal husbandry and the green revolution, it is necessary to change the existing animal husbandry production methods, to abandon feeding methods such as animal meat and bone meal and other high protein feeds, and vigorously develop organic animal husbandry. The second is to attach great importance to animal welfare and better protect and use animals. The so-called animal welfare is to allow the animals to survive in a state of recreation. The criteria include animals without any disease, no behavior abnormalities, and no psychological stress and pain. With the world increasingly attaching importance to the development of sustainable animal husbandry and food safety, we must learn profound lessons from outbreaks of severe animal epidemics and food safety problems in developed countries, learn to respect the laws of nature, and make further fuss about quality and safety. It is necessary to vigorously develop organic animal husbandry to maintain the development of animal husbandry along the path of healthy and sustainable development in China. It is necessary to continuously improve the quality of animal-originated foods in China, and at the same time meet the growing material needs of people, and at the same time enhance the competitiveness of animal foods in the international market.
According to Professor Hu Xiaosong, Ph.D. supervisor of the School of
Food Science and Nutritional Engineering, China Agricultural University,
Instant Noodles are often criticized by people who think eating is not
good for health mainly for the following reasons:
First, high fat content, because most of the instant noodles are fried way to dry the noodles. However,
Professor Hu pointed out that compared with French fries, hamburgers
and other instant noodles in the fat content is not very high, with an
average of about 16% -18% of fat, of which 11% are palm oil, that is, Human health beneficial vegetable oil, and a hamburger in an average
of about 30% of fat, nearly twice as much as instant noodles.
Second, contain certain additives. Professor
Hu said that when it comes to additives we talk about change, I think
it is not conducive to the health of the material, which is the concept
of a misunderstanding. The food industry can not do without thickeners, stabilizers and other
additives, the country allows the use of, are strictly tested to prove
harmless to the human body, we can rest assured that consumption.
Third, many people are concerned about the problem of acrylamide. Professor
Hu pointed out that all starch-based foods in the high-temperature
cooking (over 120 ℃) will produce this carcinogen, therefore, there
are french fries, instant noodles, there must be.
