Highly purified tocopheryl phosphate, process for producing the same, analytical method therefor and cosmetic

Disclosed herein are a highly purified tocopheryl phosphate and / or a salt thereof (tocopheryl phosphates) wherein a P,P'-bistocopheryl hypophosphate and / or a salt thereof (P,P'-bistocopheryl diphoshates) is contained in a proportion of not higher than 3% by weight; a process for producing a highly purified tocopheryl phosphate and / or a salt thereof, which comprises the steps of reacting a tocopherol with an oxyphosphorus trihalide followed by treating with an acid or basic aqueous solution to thereby form tocopheryl phosphates (i) in which P,P'-bistocopheryl diphoshates (ii) formed as by-products are contained, hydrolyzing the P,P'-bistocopheryl diphoshates (ii) under acid condition, and, optionally, rendering the hydrolyzate neutral or basic under basic condition; and a method of analyzing tocopheryl phosphates, comprising analyzing a sample containing components (i) and (ii) with the use of a high-performance liquid chromatograph column packed with a gel of a polymethacrylate having, bonded thereto, long-chain alkyl groups. None or only an extremely minute amount of P,P'-bistocopheryl diphoshates are contained in the highly purified tocopheryl phosphates, so that the highly purified tocopheryl phosphates exhibit antioxidant and blood circulation promoting effects, have excellent water solubility, are powdery so that the handling thereof is extremely easy, are free from cutaneous irritation and allergenecity and ensure dermal safety. Therefore, the highly purified tocopheryl phosphates are useful as cosmetic ingredients. The amounts of components (i) and (ii) can be simply measured with high accuracy by the above method.

Spice composition for inhibiting food spoilage microorganisms

The invention discloses a spice composition for inhibiting food spoilage microorganisms, which consists of the following raw materials in percentage by weight: 30 to 50 percent of cinnamic aldehyde, 20 to 45 percent of eugenol, 20 to 40 percent of thymol, and 5 to 25 percent of salicylaldehyde. The eugenol, the cinnamic aldehyde, the thymol and the salicylaldehyde come from essential oil or natural-identical edible spices which are rich in the spices; components of the spice composition can be directly mixed, dissolved evenly and then used according to the proportion, or are dissolved and diluted by adopting solvents such as water, edible alcohol, propanediol, and grease to use, or are dispersed evenly by adopting other carriers such as dextrine and starch to use; the material selection of the spice composition is natural, safe and nontoxic; the co-synergistic action among spice ingredients ensures that the composition is highly-efficient and broad-spectrum to inhibit the food spoilage microorganisms; the spice composition has small usage amount, and can not apparently affect the flavor of food; and the spice composition is added into various food to effectively inhibit the growth and propagation of microorganisms which cause the food to spoil and deteriorate, thereby preventing spoilage of the food and keeping the food fresh.
