501 Liquid Determination of Vitamin B1

501 Liquid Determination of Vitamin B1 Vitamin B1 found in one of the first vitamins. White crystal or crystalline powder; a weak special smell, bitter, hygroscopic, when exposed to the air, easy to absorb moisture. In alkaline solution easily decomposed deterioration. PH 3.5 at 100 ℃ high temperature resistant, pH greater than 5, prone to failure. In case of decreased potency of light and heat. It should be placed shading, save a cool place, not long storage. Very stable in an acidic solution, stable in alkaline solution, easily oxidized and heat damage. Reducing substances sulfites, sulfur dioxide and other enables vitamin B1 inactivation. Currently feeds are added a variety of vitamins to ensure healthy growth of the animals. If the animal is completely missing one or several kinds of vitamins, or insufficient intake of certain metabolic processes will be damaged, leading to stunted growth or disease. Vitamin B1, also known as thiamin or antineuritic vegetarian, animal growth process, a lack of vitamin B1 can cause growth retardation, cause gastrointestinal disease, cardiac enlargement and myocardial steatosis. Referring to GB / T14700-2002 "Determination of dietary vitamin B1" tournaments Technology Analysis Laboratory of 501 high-performance liquid chromatography 4% Laying of premix was measured. In recent years, the rapid development of China's feed industry, feed production increased year after year, has become the world's largest producer of feed. Consequent feed quality and safety issues aroused great concern because feed is safe or not will affect human health through animal products, and therefore monitoring of feed quality is very necessary. 2012, the state has promulgated the "feed and feed additives regulations", "feed and feed additives production license management approach", "feed production enterprise license conditions" and "mixed feed additives manufacturing enterprises permit conditions" and other regulations, to feed producers a higher detection equipment and personnel with the requirements. Technology tournaments for the feed new regulations, to carry out inspection solutions work on vitamins, amino acids, melamine, metal elements and the like. This is measured with you about dietary vitamin B1, refer to GB / T14700-2002 Determination of Vitamin B1. Vitamin B1 promotes growth; help digestion; maintain nerve tissue, muscle, normal heart activity and so on. In addition, vitamin B1, or heart, nervous and digestive systems necessary to maintain normal function.
