Description

A kind of compound emulsion thickener and include its soft ice cream size
Technical field
The invention belongs to food technology fields, are related to a kind of frozen, and in particular to one kind is used to produce soft ice cream Compound emulsion thickener and include its soft ice cream size.
Background technology
Soft ice cream is a kind of a kind of semi-fluid solid-state version frozen dessert produced using special soft ice-cream machine, due to Not by cure process, therefore the special mouthfeel of soft ice cream is fine and smooth mellow and full fragrant sliding.Compared to normal ice cream, soft ice cream Dairy fat content it is relatively low (3~6%VS 10~18%), and air content is higher (up to 60%), so receive vast consumption Person, which especially likes to be beautiful, is afraid of the favor of fat personage.
In Chinese market, for make the raw material of soft ice cream at present mainly in the form of premixed powder based on, during making First premixed powder is mixed in a certain ratio to place into freezing machine after reconstituting with water, cow's milk and is congealed, but due to different operating personnel Weighing accuracy and skilled operation degree difference, it is easy to product is caused sensory difference occur.In order to meet to soft ice cream The demand of the standardization of products, research staff are dedicated to the soft ice cream size that exploitation can be used directly.According to soft ice cream size The difference of shelf-life can be divided into short shelf-life low-temperature pulp and long two kinds of shelf-life room temperature slurry, it is obvious that room temperature soft ice cream Slurry has incomparable advantage, but it needs to solve the mouthfeel of congealing of stability problem and product in the shelf-life simultaneously and asks Topic, therefore the technology fort that always industry is not yet broken through.
Room temperature soft ice cream size currently on the market is allocated using acid adding or flavor substance, for example, Chinese Patent document CN106306323A disclose it is a kind of can room temperature preserve the acid soft ice cream size of 6 months, be by using By 20% acid solution that citric acid and lactic acid are configured to by for make the mixed raw material pH value of slurry adjust to 4.25~4.35 and .Although above-mentioned room temperature soft ice cream size with certain Yoghourt mouthfeel, its be not by lactobacillus-fermented and Lai, because And do not have the pure flavor and nutritive value of real Yoghourt yet.For this purpose, fermented type soft ice cream size comes into being, but existing Fermented type soft ice cream size but can not room temperature preserve, this is because slurry is susceptible to albumen under acid, normal temperature condition Phenomena such as denaturation, fat crystallization, water-oil separating, whey are precipitated.Thus, not yet occur really sending out by Yoghourt in the prior art Room temperature soft ice cream size made from ferment technique.
