A kind of anhydrous biscuit oil and preparation method thereof
Technical field
The invention belongs to food processing technology field, be specifically related to a kind of anhydrous biscuit oil and preparation method thereof.
Background technology
At present the industry of curing of China has occupied consequence in food industry, baked the industry turnover in 2008 to arrive 77,800,000,000 yuan, and nearly ten million ton of each confectionary annual output, wherein the output of biscuits is about 4,560,000 tons.In biscuit especially shortbread type biscuit production process, the use amount of grease is very big, and particularly all kinds of special fats with better shortening property are as shortening, hydrogenated vegetable oil, animal fat etc.But each above-mentioned quasi-grease can bring preferable color, matter structure quality to biscuit on the one hand; But these greases generally contain the saturated fatty acid of high level on the other hand, hydrogenated vegetable oil even contain trans-fatty acid, and this has brought adverse effect for the consumer health.
Consideration for the above reasons, the technical staff has paid a lot of effort and has used various fatty substituents to reduce the content of saturated aliphatic acid in the food.The patent CN200810235930.X of Southern Yangtze University told about the use wheat bran add make after the PROCESS FOR TREATMENT such as enzyme hydrolysis, spray-drying the polysaccharide fat substitute; The patent CN201010271835.2 of He'nan University of Technology has told about and has made the polysaccharide fat substitute after the use corn peel adds industrial treatment such as enzyme hydrolysis, spray-drying.The fat replacement product that make through above-mentioned technology are similar to hydrophilic colloid, are applicable to that in the water content high product, as cake, bread, and organoleptic attribute affects adversely in biscuits.
Tell about among Southern Yangtze University's patent CN200510038696.8 in addition and use soybean oil, emulsifying agent, hydrogenated vegetable wet goods to prepare the fluidised form shortening of freezing flour-dough special use, this product can better satisfy the needs that freezing flour-dough is produced, but used hydrogenated oil and fat in the patent, there is the problem that contains more saturated fatty acid and trans-fatty acid, use a large amount of vegetable oil simultaneously in this patent, may cause the not long keeping adverse consequences of the patented product.
Summary of the invention
The object of the present invention is to provide a kind of anhydrous biscuit oil.
The present invention also aims to provide a kind of preparation method of anhydrous biscuit oil.
A kind of anhydrous biscuit oil, this anhydrous biscuit oil comprise the vegetable oil of 60-90wt%, the molecular clock monoglyceride of 2.5-10wt%, the citric acid glyceride of 2.5-10wt%, the phytosterol of 4-35wt%, the Tea Polyphenols of 0.5-5wt% and the rosemary, of 0.5-5%.
Described vegetable oil is selected from one or more in rapeseed oil, sunflower oil, peanut oil, rice bran oil, the soybean oil.
A kind of preparation method of anhydrous according to claim 1 biscuit oil, vegetable oil, molecular clock monoglyceride, citric acid glyceride, phytosterol, Tea Polyphenols and rosemary, are poured in the reaction vessel of lid and mixed, 2-20min in temperature 65-80 ℃ water-bath, handle 2-20min through high-speed homogenization machine 8000-20000r/min then, again it is chilled to 10-20 ℃ in 10-30min, returns back to 23-26 ℃ and get product.
Beneficial effect of the present invention: (1) base-material of the present invention, do not contain saturated fatty acid, trans-fatty acid, health there is bigger help.(2) the present invention contains phytosterol, for reduction blood fat, reduction cholesterol certain usefulness is arranged.(3) the present invention contains the natural Tea Polyphenols, can make product have the longer shelf-life, for removing human free radical certain effect is arranged simultaneously.(4) method of the present invention is simple to operate, and raw material is simple and easy desirable, makes things convenient for plant layout production.(5) viscoelastic properties of dough of using grease of the present invention to make is moderate, and biscuit matter structure is crisp, the no fuel-displaced phenomenon in surface.(6) the present invention uses citric acid glyceride as main emulsifying agent, can play emulsifying effectiveness, can serve as the antioxidant synergist again, reduces the additive use amount, reduces cost.
The specific embodiment
The present invention will be further described with specific embodiment below.
