China, as one of the world's largest food producers and consumers, pays a lot of attention to food safety issues. In recent years, China has taken actions and implemented a series of plans in respect to food safety. Food safety control systems including regulatory, supervisory, and science and technology systems, have begun to be established in China. Using, as a base, an analysis of the current Chinese food safety control system as measured against international standards, this paper discusses the need for China to standardize its food safety control system. We then suggest some policies and measures to improve the Chinese food safety control system.展开更多

Many methods are used to preserve the juice or the paste through drying and with addition of preservative. Tomato grows under ambient conditions or in green houses at a temperature of 20°C - 27°C with high contents of vitamins A and B, potassium, iron, and phosphors. Tomato is a source of fiber;it doesn’t contain sodium salt, fats, or cholesterol;in fact it is the cheapest food of the poor common people. Tomato while waiting for processing to paste deteriorates rather quickly, and shall be thoroughly rinsed with sterilized clean water using rotary washers. The washed tomato is inspected, sorted, and chopped. The tomato liquor is processed through an extraction unit where the juice is separated away from outer skin, seeds and fibers. To avoid oxidation and foaming the tomato liquor is deaerated;the juice is deaerated by taking the vacuum as soon as it is formed. A double-effect evaporator is used to concentrate the tomato liquor under partial vacuum of 0.5 atmospheres;this is important to minimize heat damage, oxidation and dark color. The tomato paste is then sterilized with small amount of non-harmful preservatives and then canned, labeled and sent to store. To achieve the international standard specifications and metrology organization a control system is developed, tuned and analyzed for stability conditions. It is recommended that a tomato production plant has to be constructed in countries like Sudan and other countries with similar weather conditions.展开更多

Starting from the local role of primary producers, North-South and South-South networking (www.noodlesonlus.org) is needed to share solutions for transnational problems like climatic change, contaminated agro-farming sites and food waste and losses in the era of food crisis.
