維生素B15生產(chǎn)廠家 維生素B15廠家 

一、簡介

   維生素B15品名：維生素B15、潘氨酸

   維生素B15英文：Vitamin B15

   維生素B15 CAS號：有

二、性狀

白色至黃色細小晶體。通常為單斜晶系的針狀或板狀晶體的α型，β型為斜方晶系的細微針狀晶體。純品無臭，通常因所含硫的微量分解產(chǎn)物而帶米糠臭。有苦味。無水品暴露在空氣中迅速吸收4%的水份。對熱穩(wěn)定（170度）。干燥狀態(tài)下于空氣中穩(wěn)定，能長時間保存，因吸濕而緩慢分解著色。1%水溶液的PH值為3.13。水溶液中PH值2-4時較穩(wěn)定。PH值5.5以上時，加熱不穩(wěn)定。遇紫外線則分解。約于248度熔化并部分分解。極易溶于水（1∶1）。溶于乙醇、甘油、丙二醇。不溶于苯。

三、用途

營養(yǎng)增補劑。因本品為水溶性且在堿性下易分解，在食品加工、烹調(diào)時損失大，并有異味發(fā)生，故常采用硫胺素的其他衍生物?？商砑佑诎酌?、小麥粉、面包、面條、醬油、乳制品、人造奶油、糕點、清涼飲料果醬等食品。應按食品形態(tài)選用各種硫胺素衍。

2. Characters

White to yellow fine crystals. It is usually α-type of monoclinic needle-like or plate-like crystals, and β-type is orthorhombic fine needle-like crystals. The pure product is odorless, usually with the smell of rice bran due to the trace decomposition products of sulfur. Bitter taste. Anhydrous products quickly absorb 4% moisture when exposed to air. Stable to heat (170 degrees). It is stable in the air in a dry state, can be stored for a long time, and is slowly decomposed and colored due to moisture absorption. The pH of a 1% aqueous solution is 3.13. It is more stable when the pH value in the aqueous solution is 2-4. When the pH value is above 5.5, the heating is unstable. Decomposes when exposed to ultraviolet light. Melts and partially decomposes at about 248 degrees. Easily soluble in water (1:1). Soluble in ethanol, glycerol, propylene glycol. Insoluble in benzene.

3. Use

nutritional supplements. Because this product is water-soluble and easily decomposed under alkaline conditions, the loss is large during food processing and cooking, and peculiar smell occurs, so other derivatives of thiamine are often used. It can be added to white rice, wheat flour, bread, noodles, soy sauce, dairy products, margarine, cakes, refreshing drinks, jams and other foods. Various thiamine derivatives should be selected according to the form of food.
