Technical field
The present invention relates to a kind of composition for food emulsification and preparation method thereof, belong to food processing technology field.
Background technology
Food emulsifying agent is the most popular surfactant of food service industry, is processed in these emulsifying agents with natural material
Surfactant mainly have the series of products such as monoglyceride, sucrose ester, polyglycerol ester.Food emulsifying agent in the range of our times
Dosage is more than 400,000 tons, and the dosage of China's food emulsifying agent, at 80,000 tons or so, wherein monoglyceride yield in China's has reached 4
Ten thousand tons, occupy 50% of food emulsifying agent or so.Polyglyceryl fatty acid ester(Abbreviation polyglycerol ester, PGFE)It is FAO/WHO food additives
Add the agent Committee of Experts to announce one of more than 30 kinds of safety food emulsifying agent used, be the food breast for being only second to monoglyceride abroad
Agent, it is widely used in bakery product, margarine and beverage.Further, since its colorless and odorless, and it is not susceptible to water
Solution, has no adverse effects to product appearance, smell, can be compounded with other emulsifying agents, have good synergistic function, therefore
Its application also progressively expands to daily use chemicals, oil, weaving, medicine and other fields, and product market capacity is big.And China's polyglycerol ester
The starting and development of industry are relatively later, and the hierarchy of skill is relatively low.Domestic polyglycerol ester unstable product quality, kind
It is single to have met multi-level, conglomerate, the present situation of multi-field actual demand, therefore to high-quality, multi items polyglycereol
The research of exploitation and its application of ester meets the urgent need of the country, has very high social and economic benefit.
Mono fatty acid glyceride(Abbreviation monoglyceride, MG)It is a kind of very important nonionic surface active agent, it has
Have good emulsibility, dispersiveness, lubrication and solubilising, thus be widely used in food, medicine, cosmetics, printing and dyeing, metal add
The industry such as work.Monoglyceride can occur interaction with grease, protein and carbohydrate and form a species complex,
The effect such as emulsification, scattered, fresh-keeping is played in.To arrange more relaxed crystallization, β types crystallize the crystallization of α types in monoglyceride
It is then the stable crystallization of compactness arrangement.The all β types crystallizations of kind of market sale, the crystallization of α types and β types crystalline phase ratio, α types
The crystallization not only good dispersion in water, and foaming characteristic and other performance crystallize also superior to β types.
Tripolyglycerol monostearates are used as emulsifying agent and foaming agent in bakery product, grease is disperseed in dough
Be more uniformly distributed, produce stable tiny bubble, volume significantly increases, and makes the soft body of Bread and Cakes big, springiness, internal junction
It is spongy in structure, and have certain preservation, freshness date can be made to extend 4~5 days, be not hardened, be not scaling-off.In biscuit also
Its crispness can be improved, makes biscuit be easy to be stripped in process of production, decorative pattern is clear.
The A of patent application CN 103091451 disclose a kind of detection method of single stearic acid glycerine lipoprotein alpha-crystal, the detection
Method uses periodate oxidation method determination method on the basis of existing single stearic acid glycerine lipoprotein alpha-crystal method, in detection process
CCP be defined, it is determined that sample pre-treatments optimum treatment mode and sulphur
The Best Times of sodium thiosulfate titration.The A of patent application CN 102550829 disclose a kind of feed fat that improves and disappeared
The feed emulsifier of rate, its quality group turn into:Monoglyceride 3.0~10.0%, sucrose ester 5.0~15.0%, three polyglycerol esters
25.0~35.0%, lipase 0.5~1.5%, zeolite powder 38.5~66.5%.It can improve feed fat digestibility 10~30%
Left and right, so as to reduce grease amount 20~30%, reduce feed cost.
