  • Patent number: 11297864
    Abstract: The present invention relates to an apple enzyme for efficient reconstruction of an intestinal microecology and a processing technology, which comprises the following steps: (1) pretreating raw materials; (2) pulping; (3) detoxifying patulin: firstly biologically detoxifying the pulp: inoculating inoculating plant Lactobacillus (ATCC 8014) into the pulp, adjusting the pH to 3-7 at the temperature of 20-30° C., stirring, and detoxifying for 20-24 h; and then repeatedly absorbing and filtering with a carboxylation nano multiwall carbon-neutral aluminum oxide filter screen for three times; and (4) carrying out the division intensified and dynamic fermentation. For the problems of the apple enzymes such as low fermentation efficiency and long time, the division decompression dynamic intensified fermentation method of substrates is used, so that the high-speed and high-efficient fermentation of the apple can be realized, and the fermentation time can be greatly shortened.

  • Patent number: 11116230
    Abstract: The present invention relates to a method for three-dimensional microwave air-jet drying of persimmon slices, comprising steps of grading and cleaning, slicing, microwave heating, steam de-astringency, hot-air reverse primary drying, negative-pressure intermittent secondary drying, cooling and packaging. In the present invention, high-temperature (60-70° C.) high-pressure annularly sprayed citric acid and 40% alcohol vapor (rotating at 360°) are adopted to remove astringency of persimmons, wherein high temperature causes more intense Brownian motion of liquid molecules; high pressure improves permeation and diffusion speed of de-astringency liquid in the persimmon slices; citric acid plays a membrane breaking role on persimmon cell membranes; and 40% alcohol vapor is allowed to rapidly diffuse into cells, so that tannin is polymerized into insoluble gel from a soluble state, thereby achieving a uniform and rapid de-astringency effect.

  • Publication number: 20210123002
    Abstract: The disclosure relates to an appetizing and summer heat relieving tangxin raw cider and a high-efficiency deep processing technology thereof. The high-efficiency deep processing technology comprises the following steps: (1) preparing raw pulp; (2) detoxifying patulin; (3) inoculating and precisely fermenting; (4) performing enzymolysis of residues; (5) clarifying and filtering; (6) ageing; and (7) canning after adsorbing and clarifying. According to the disclosure, aiming at a phenomenon that cider is muddy after being stored, it is solved by adsorption with a multi-stimuli responsive nano fiber modified resin. Exterior stimuli include change in environment temperature or acidity-basicity (pH value), light, electric field, magnetic field or specific molecules. In response to exterior stimuli, nano fiber may include physicochemical properties such as size, hydrophilicity and hydrophobicity, refractive index, transmittance, mechanical strength, color or conductivity.
