JPS60102169A - Carotenoid-containing composition and its production - Google Patents

Abstract

PURPOSE:To produce the titled composition having excellent discoloration stability, and useful as a colorant or a vitamin A source in the form of vitamin A precursor, by dissolving a carotenoid in vitamin E under heating. CONSTITUTION:A carotenoid (e.g. alpha-carotene) is dissolved in vitamin E (e.g. alpha- tocopherol) under heating. If necessary, a solution or dispersion of an antioxidant, a surface active agent, a density modifier, etc. is added to the above mixture, and the product is emulsified or pulverized with an emulsifier such as a homomixer. The produced oil phase of vitamin E containing the carotenoid can be supplied as it is according to the use such as a source of vitamin A or vitamin E, etc., or can be encapsulated to microcapsules.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a vitamin E composition containing carotenoids and a method for producing the same.

Carotenoids are frequently used as coloring agents for foods and drinks, medicines, etc., and as a source of vitamin A in the form of vitamin Ar'illK. However, carotenoids are hardly soluble in common solvents such as water and alcohol, and for this reason, the solvents that can be used are limited. In conventional carotenoid-containing compositions, carotenoids are extracted from animal and vegetable oils (e.g., soybean oil, corn oil, rapeseed oil, squalene, squalane, lemon oil, orange oil, etc.) or halogenated organic solvents (e.g., In these conventional techniques, a composition was used, which was dissolved in carbon tetrachloride, etc., and further emulsified or powdered with an aqueous solution containing a surfactant, a polymeric substance, etc. 41F (When using commercial oil, it depends on its fI'9A, but the decolorization stability of the dissolved carotenoids is poor, there is a peculiar odor, or the solubility is not sufficient to dissolve the carotenoids. In addition, when essential oils are used, there are safety issues such as the risk of ignition at zero temperature. However, there were problems with safety and health during production, and in any case, IJ was not always fully satisfactory for effectively converting carotenoids.

In order to solve the above-mentioned problem, the present inventors conducted various studies on solvents for dissolving carotenoids, and found that carotenoids dissolve in vitamin E by heating. The present invention was completed by discovering that the carotenoid-containing vitamin E composition obtained by emulsifying or powdering the carotenoid-containing vitamin E composition as a coloring agent or vitamin A source is a t-group acid. The present invention aims to provide a novel composition obtained by dissolving carotenoids in vitamin E, which has not been known as a solvent for dissolving carotenoids, and a method for producing the same. To produce the wax composition of the present invention, carotenoids are dissolved in vitamin E by heating, and if necessary, the emulsified eggs are further pulverized.

Carotenoids include synthetic carotene, β-carotene, r-carotene, canthaxanthin, bixin, methylbixin, cryptoxanthin, xanthophyll, etc., or esters of their hydroxyl or carboxyl derivatives. can be used alone or in combination.

Examples of vitamin E include synthetic or natural α-tocopherol, β-1-copherol, 2-tocopherol, δ-tocopherol, ε-tocopherol, tartcopherol, q-tocopherol, and the like. Acids or esters with nicotinic acid, etc., and their d, /- or (1/, isomers, etc.) can be used alone or in mixtures. To dissolve, the dissolution conditions should be set appropriately so that the concentration matches the desired drug.9 If the carotenoids in vitamin E are low in 111, the lower the temperature, and vice versa, the lower the carotenoids in vitamin E. If the content of carotenoids is high, it is sufficient to dissolve them at high temperatures.Usually, carotenoids have a ratio of 0.0 to vitamin E.
Add vitamin E to 50°C to 1 to 20%.
It can be dissolved by heating to 60'C.

The vitamin E111 in which carotenoids are dissolved may further contain other ingredients as necessary, such as BUT, B I
(A, esters of gallic acid or ascorbic acid,
Natural and synthetic antioxidants such as erythorbic acid, ascorbic acid, gallic acid, chrysin phytate, gelatin, sucrose fatty acid ester, glycerin fatty acid ester,
Surfactants such as sorbitan fatty acid ester, propylene glycol fatty acid ester, gum arabic, guar gum, and gum tragacanth; density regulators such as glycerin, propylene glycol, and sorbitan; lecithin and/or polyglycerin fatty acid ester, etc. may be appropriately contained. You can leave it there.

Vitamin E containing carotenoids etc. prepared in this way
The oil phase can be provided as it is or can be encapsulated into microcapsules or soft capsules depending on the intended use as a coloring agent, a source of vitamin A or a source of vitamin E, etc.

Furthermore, the oil phase of vitamin E, which contains carotenoids, etc., is prepared by dissolving or dispersing the above-mentioned general natural or synthetic antioxidants, surfactants, specific gravity adjusting agents, etc. in water phase components, for example, water as appropriate. It is also possible to prepare an 0/W type emulsion by mixing the mixture with the above-mentioned mixture and emulsifying and dispersing it by a known method using an emulsifying and dispersing machine such as a homomixer or a homogenizer. Further, this O/W type emulsion can be further pulverized by conventional techniques such as spray drying and freeze-drying, depending on the composition set to enable pulverization.

As explained above, the composition of the present invention has far superior decolorization stability compared to compositions according to the prior art, and is an excellent composition as a coloring agent or a source of vitamin A as a vitamin A nil receptor. be. It is also an excellent composition in terms of the use of vitamin E, which is a solvent, as a source of energy and N.

Example 2 1 part of β-carotene crystals was added to 9 parts of dz-α-1 acetate and cofferol, and the mixture was stirred and heated to about 120°C. After 1 hour, the β-carotene was completely dissolved. Even when this was cooled to room temperature, no crystals were precipitated, and a dark red oily β-carotene-vitamin E composition was obtained.
