New and efficient food preservative – the production of glycerol monolaurate – food additives, additives – Food Industry
"The People's Republic of China Food Hygiene Law," Chapter IX, Article 54 provides Food Additives Means to improve food quality and color, smell, taste, and for the preservation or processing into food needs of the chemical synthetic or natural material. Nutrition Enhancer That nutrients added to food to enhance the natural or synthetic natural nutrition is the scope of food additives.
People in the face of the twenty-first century, the consumption structure and higher levels of challenge, research and development of new Food processing Industry to improve food varieties and production, make full use of new resources of food is the only way the food industry. Food additives in the promotion of food processing to high-quality, high yield, low power aspects of development, no doubt a huge role. Its output is small, accounting for less than 2% of the total output of food industry, but the effect is great. Food additives have been in improving the quality of food, quality, and strengthening and feel, enhanced nutrition, improved food processing conditions to prevent spoilage, extend shelf life of food, play a crucial and indispensable role, can be said that no modern Food additives industry, there is no modern food industry, food to raise the grade, to improve pay value-added, better access to family meals, ingredients and food additives must follow the path, it is inevitable. Food additives can be said is an important pillar of the modern food industry.
Trace elements (minerals), the human body by various chemical elements, the quality and quantity are elements with similar surface crust. In the presence of more than 90 kinds of crust surface elements can also be found in the human body. According to the content in the human body can be divided into macro and trace elements in two categories: macro elements, also known as major element, its content, in proportion more than ten-thousandth of the total weight of the body. Include oxygen, carbon, hydrogen, nitrogen, sulfur, calcium, phosphorous, sodium, potassium, chloride, magnesium 11 species; trace element content in the body means less than one ten thousandth of body weight, but also that humans and animals in the levels less than one ten thousandth of weight, but also that humans and animals in the levels of iron and iron content equal to or less than the elements of said trace elements. Trace elements according to the needs of the body of the case, can be divided into non-essential trace elements and essential trace elements. Not refer to the so-called essential when the lack of life-threatening, but that will cause a lack of biological function and structural abnormalities of the body, causing disease. At present, the most recognized essential trace elements: iron (Fe), copper (Cu), zinc (Zn), cobalt (Co), manganese (Mn), chromium (Cr), molybdenum (Mo), Nickel (Ni), Vanadium (V), tin (Sn), silicon (Si), selenium (Se), iodine (I), fluorine (F), 14 . May be necessary to have strontium (Sr), rubidium (Rb), arsenic (As), boron (B) where B is the essential element of plants.
Present, its biological role has not yet found a clear toxic element known as non-essential trace elements, will be divided into essential and non essential trace elements, toxic or harmless, only relative significance. Even with a trace element, is useful when low concentrations, high concentrations may be harmful (such as fluorine, selenium, etc.), so the trace element concentration of the biological effects and safety of a more in-depth study in order to prevent blind excessive intake of essential trace elements, or from the diet may be necessary to remove some kind of "toxic" elements.
Food additives are indispensable to today's people's lives, but there are restrictions on the amount and scope. And trace elements are closely related, such as the calcium source with enhanced active calcium, calcium lactate, biological calcium carbonate; iron enhancer are ferrous sulfate, ferrous lactate, ferrous gluconate, ferrous pyrophosphate, ferric citrate ammonium, etc.; zinc enhancer are: zinc sulfate, zinc gluconate, zinc oxide, etc.; iodine enhancer with potassium iodide, iodine seaweed powder; copper enhancer are: copper gluconate, copper sulfate; magnesium reinforcement are: magnesium oxide, magnesium, zinc, etc.; iodine enhancer with potassium iodide, iodine seaweed powder; copper enhancer are: copper gluconate, copper sulfate; magnesium strength of agent are: magnesium sulfate, magnesium oxide and so on. Selenium is a toxic trace elements is essential, therefore, demanding the strengthening of selenium, it was reported that selenium levels in the human body per ml of whole blood calculated with the Chinese was 42 ng (range 6-52), human Diet Selenium containing 0.01PPm can, according to the majority of food consumption per day, converted to 0.1PPm selenium intake of adults in daily 50-200ug.
