Description
Technical field
The present invention relates to micro emulsion carrier of a kind of food technology field and preparation method thereof, specifically is a kind of O/W type food level beta-carotene microemulsion carrier and preparation method thereof.
Background technology
Beta carotene is most important a kind of in the carotenoid, water insoluble, be slightly soluble in vegetable oil, in aliphatic and aromatic hydrocarbon medium dissolubility arranged, the solubility in n-hexane is 3mg/g, be soluble in most chlorinated hydrocabon, as chloroform etc. (Chen Zhihui, Chen Fahe, Feng Zuoshan etc. the character of natural Beta-carotene and Study on Preparation progress [J]. food industry science and technology, 2005,6 (6): 86-189).Beta carotene is because of containing conjugated double bond structures in its molecule, meets oxygen, light and heat are easily oxidized.Beta carotene is a kind of natural colouring matter that is most widely used, and is the food additives that country allows use, has painted and the nutrition double action.Beta carotene is put into the state food additive use sanitary standard GB-2700-81 of the People's Republic of China (PRC) as colouring agent and nutrition fortifier.But, the unstability of beta carotene with and low-solubility it is very restricted at beverage and other Application in Food.The at present both at home and abroad main carrier that adopts microcapsules, cyclodextrin, liposome etc. as beta carotene, beta carotene is easily oxidized and water insoluble to wait deficiency to overcome, but the preparation process more complicated of these carriers, cost is higher.
Components such as surfactant, cosurfactant, oil, water are mixed under proper condition, can as clear as crystal, the low viscous thermodynamic stable system of spontaneous formation outward appearance, i.e. microemulsion.It both can be used as the carrier of oil soluble material, also can be used as the carrier of water-soluble substances, have toxicity little, safe, do not need special installation advantage such as can produce in a large number, industry (Cui Zhenggang such as medicine, cosmetics, food have been widely used in, Yin Fushan. emulsifying technology and application [M]. Beijing: China Light Industry Press, 1999.75～79).
Find through literature search prior art, Zhou Yiping, Yan Chunli, repair will dragon etc. and delivered " research of β-carrotene-β-cyclodextrin inclusion compound " the 24th～27 page of " meticulous and specialty chemicals " 2005 the 13rd the 13rd phase of volume, mention in the literary composition, β-carrotene-β-the cyclodextrin inclusion compound of week happy equality preparation, the beta carotene survival rate is respectively 80%, 70%, 60%, 55.9% 2 days, 4 days, 10 days, 14 days the time under room temperature, room light illuminate condition.
Summary of the invention
The objective of the invention is to overcome deficiency of the prior art, a kind of O/W type food level beta-carotene microemulsion carrier and preparation method thereof is provided.The present invention is simple, and the beta-carotene microemulsion carrier of gained can make mass fraction that beta carotene dissolves in water up to 1%, has greatly improved the stability of beta carotene simultaneously.
The present invention is achieved by the following technical solutions:
The present invention relates to a kind of O/W type food level beta-carotene microemulsion carrier, the solvent of this carrier and percentage by weight are: Tween80 1%～50%, ethyl butyrate/ethanol 1%～40%, water 10%～98%.
Described Tween80, by weight percentage, its preferred proportion is 15%.
