Almost odorless. Melting at 263 to 264 ° C and de*position. Usually more stable, high humidity of 60% or less stable, more than 60% is generated dihydrate. Vitamin C and vitamin K3 coexistence coloring. Alkaline conditions exist heated directly with reducing sugars break down. Soluble in water (40g/ml, 35 ℃), the aqueous solution was neutral to slightly acidic, heated together with the phosphoric acid, hydrochloric acid, sodium hydroxide, an ion exchange resin or the like, since racemization. Lysine essential amino acids can not be synthesized in the body, such as the lack of cause protein metabolism disorder and dysfunction, leading to growth failure, hypoplasia, weight loss, loss of appetite, reduced blood protein. The D-type lysine no physiological effect. Edit this paragraph quality standard GB 10794 - 89, the mandatory international Project quality control standards Content (dry basis) ≥ 98.0% Heavy metals (Pb) ≤ 0.001% Transmittance (E10% 1cm: 400nm) ≥ 95% Loss on drying (105 ℃, 3h) ≤ 1.0% Arsenic (as As, GT-3) ≤ 0.0001% Residue on ignition ≤ 0.2% Specific Rotation [α] 25D 19.0 ° to +21.5 ° PH (10% aqueous solution) 5.0 to 6.0 Function: Nutritional supplements. Lysine is used to strengthen the food. Rye, rice, corn, peanut powder contained lysine as limiting amino acids, wheat, sesame seeds, oats contained lysine as the first limiting amino acid. Can still be used for mayonnaise, milk, instant noodles and food. Can also be used as a seasoning to improve the flavor. Edit this paragraph Re*mended dosage and precautions adult daily minimum requirement (L-lysine) of: a male ofabout 0.8 g,about 0.4g women, young people 12 to 32mg/kg, the child care 180mg/kg (1g lysine acid equivalent of L-lysine hydrochloride 1.25 g) Can be safely used in food in toxicity: Edit this paragraph packaging and transport packaging: This product adopts double packaging: the inner edible polyethylene plastic bag sealed, topical cardboard box packaging. Per carton net content of 25kg, and can also be packaged according to user needs. Transport: light loading and unloading. Against sun, rain, and can not be mixed with toxic and harmful goods shipped, the product is non-dangerous goods, according to general chemical transport. Storage: Store in a dry clean dark environment with toxic substances to mix, in order to avoid contamination. The shelf life of two years.
