Flash drying method for fruits and vegetables through pulse pressure difference

The invention discloses a flash drying method for fruits and vegetables through pulse pressure difference. The flash drying method comprises the following steps: (1) putting pretreated fruits and vegetables in a drying bin after heating, and then carrying out pressure relief on the drying bin; (2) carrying out pressure boost on the drying bin, and carrying out pressure maintaining; (3) carrying out pressure relief on the drying bin; (4) heating the drying bin; (5) repeating the step (2) to the step (4) until the mass moisture content of the fruits and vegetables is 10-25%; carrying out vacuum drying to realize drying for the fruits and vegetables. The flash drying method has the advantage that high-temperature and high-pressure water inside the fruits and vegetables is subjected to explosively acute gasification for multiple times, so that quick migration of the water towards the outside of the materials is realized. Quick dehydration of the materials can be realized through the repeated pulse flash evaporation, so that the drying time is greatly shortened, the drying efficiency is improved, and the cost is reduced; moreover, pores among internal organizational structures of the materials are increased, so that the product has the unique crispy mouthfeel and character, and nutrient substances are better stored.

The invention provides gas-production fermented milk, flavored fermented milk and preparation methods thereof. The gas-production fermented milk is a product including fine bubbles, which is prepared from fresh raw milk or reconstituted milk as a raw material and through processes of sterilization and inoculation of a fermentation agent comprising lactococcus lactis subsp. cremoris, leuconostoc, lactococcus lactis subsp. diacetylactis and lactococcus lactis subsp. lactis to perform strain fermentation. The gas-production flavored fermented milk is a product including fine bubbles, which is prepared with the fresh raw milk or the reconstituted milk accounting for not less than 80% as a raw material with addition of other raw materials and through the processes of sterilization and inoculation of a fermentation agent comprising lactococcus lactis subsp. cremoris, leuconostoc, lactococcus lactis subsp. diacetylactis and lactococcus lactis subsp. lactis to perform strain fermentation. In the products, special lactococcus lactis is used in fermentation to generate CO2 and special flavors, wherein the majority of gas exists in the form of fine bubbles in the products. The products are refreshing in taste, are unique in texture and are suitable for various people.

Gas-producing low-alcohol-content sour bean milk and preparation method thereof

The invention provides gas-producing low-alcohol-content sour bean milk and a preparation method thereof. The preparation method of the gas-producing low-alcohol-content sour bean milk comprises the following steps of preparing a mixed solution, wherein fermentation substrates of the mixed solution comprise a sugar substrate and a bean substrate; homogenizing the prepared mixed solution, and carrying out sterilization treatment; cooling the sterilized mixed solution, inoculating a fermentation agent, and carrying out constant-temperature fermentation; and then, refrigerating the fermented sourmilk so as to perform post-ripening so as to obtain the gas-producing low-alcohol-content sour bean milk. Compound fermentation is carried out by utilizing a gas-producing lactobacillus fermentum anda saccharomyces-cerevisiae fermentation agent according to the preparation method provided by the invention so as to produce a small amount of carbon dioxide, a trace amount of ethanol, and a plurality of flavoring substances; and thus, the prepared fermented plant-type gas-producing low-alcohol-content sour bean milk is refreshing and palatable in taste, and has a slight wine aroma. The gas-producing fermented milk product has a trace amount of bubbles, as well as a very low content of ethanol, and thus, the novel sour milk is refreshing in taste and unique in texture. Pursuits of the consumers to new types and new taste of sour milk can be met by the unique flavor, as well as the refreshing and smooth taste, of the gas-producing low-alcohol-content sour bean milk; moreover, taste of traditional sour milk is also improved.
