The preparation method of the salt-reducing base suitable for acid food comprises the following steps: 1) preparation of soybean extract and lemon peel extract; 2) mixing the soybean extract and the lemon peel extract with edible glue for enzymolysis, enzyme inactivation, pH value adjustment to 6.0-8.0, solid-liquid separation, concentration and spray drying of liquid substances. The salt-reducing base has the advantages of excellent salt-reducing effect, no bad flavor, inhibition of irritating flavor of the food itself, suitability for acid food, low production cost and the like, is rich in polysaccharide and peptide and other components beneficial to human health, and is suitable for large-scale industrial production and application.

This invention discloses an antibacterial food preservation composite film based on polylactic acid (PLA) and nano-selenium, its preparation method, and its application. The preparation steps of the composite film are as follows: 1) Lemon peel extract is mixed with sodium selenite solution and reacted at 100-150℃ and pH 6-9 to biosynthesize nano-selenium (SeNPs); 2) The nano-selenium (SeNPs) obtained in step 1) is blended with a PLA solution, and polyethylene glycol is added to obtain a blend; the mass of SeNPs in the blend is 1%-5% of the mass of PLA, and the mass of polyethylene glycol is 10%-25% of the mass of PLA; 3) The blend is poured into a polytetrafluoroethylene (PTFE) casting frame and naturally cast at room temperature for 12 hours to allow most of the dichloromethane solvent to evaporate, obtaining the PLA / SeNPs composite film, i.e., the antibacterial food preservation composite film based on PLA and nano-selenium. The composite film prepared using this invention has good biodegradability and significant antibacterial properties, and can be used for food preservation packaging.

The invention discloses a brewing process of tea beer. The brewing process comprises the following steps: crushing and sieving malt; uniformly mixing the crushed and sieved malt with water to prepare a mixed solution; the mixed liquid is heated and subjected to heat preservation, sweet mash is prepared, and the heating and heat preservation processes are continuously carried out for five times; filtering the converted mash, and boiling the converted mash filtrate; a compound and hops are added into the converted mash in the boiling state, the compound is formed by compounding a Maojian extract and a lemon peel extract, and the hops are added in two times. According to the application, the Maojian tea is extracted, part of organic matters with bitter taste are preliminarily removed, and the lemon extract is used for neutralizing the taste of the Maojian tea extract, so that the bitter degree of the finished product of the tea beer is reduced, and the taste of the finished product of the tea beer is improved.
