The invention discloses an anti-aging corn powder with high carotenoid retention rate and a preparation method thereof, the preparation method comprising cleaning, threshing, blanching, beating, obtaining corn powder; gelatinization, obtaining corn paste material; adding enzyme for enzymolysis, enzyme inactivation, obtaining corn enzymolysis powder; preparing pectin-chitosan composite electrolyte gel; then mixing corn enzymolysis powder, pectin-chitosan composite electrolyte gel and sodium caseinate, after grinding, dispersion and emulsification, spray drying, and obtaining a finished product. The above-mentioned preparation method combines the spray drying microencapsulation of electrolyte gel and the spiral composite technology of straight-chain starch molecular fragments and emulsifiers to achieve the anti-aging goal of corn powder; through the spray drying process, pectin-chitosan composite electrolyte gel microencapsulation, to achieve the microencapsulation of corn carotenoids. The obtained corn powder has the advantages of high carotene retention rate, high gelatinization degree and good anti-aging effect.

The present application provides a kind of rice storage method and system for inhibiting the growth of mould, by low temperature flexible drying and biological protection coating composite pretreatment to rice, construct constant temperature and humidity, anoxic high CO2 Mould inhibition type storage environment, combined with ultraviolet pulse irradiation and natural plant extract slow-release composite inhibition intervention, real-time monitoring of storage environment parameters and rice mould growth related index, according to the monitoring results dynamic adjustment of environmental parameters and intervention strategy, realize the sustained inhibition of mould growth during rice storage period. Using the scheme of the present application, rice storage period can be extended by 3-6 months without chemical residues, while maintaining the original taste and nutritional quality of rice, solves the technical problems of traditional rice storage, such as easy breeding of mould, chemical inhibition residues, and quality deterioration.

The invention relates to the technical field of corn, and particularly discloses a biological fermentation cornflake and a preparation method thereof. The preparation method of the biological fermentation cornflake comprises the following steps: dissolving glucose, peptone and microbial growth factor mixed salt in water, adding lactobacillus plantarum freeze-dried powder, stirring, culturing, centrifuging, collecting supernate, adding a chitosan nanoparticle solution, stirring, adding algal polysaccharide-protein gel and an activated lactobacillus liquid, and stirring to obtain a pretreated bacterial liquid; and dispersing corn in water, standing, fishing out, steaming with a steamer, pressing with a tablet press, cooling, adding the pretreated bacterial liquid, stirring, fermenting, and drying to obtain the biologically fermented corn flakes. The biological fermentation cornflake is good in crispness, high in nutrient component retention rate and simple in preparation method.

The invention discloses a self-adaptive regulation and control intelligent dynamic electric field fresh-keeping device, relates to the related technical field of livestock and poultry meat fresh-keeping, and aims to solve the problems of single monitoring and data lagging of a traditional device. The self-adaptive regulation and control intelligent dynamic electric field fresh-keeping device comprises an intelligent electric field generator arranged on the outer wall of a fresh-keeping cavity, and a high-voltage electrode arranged in the fresh-keeping cavity and configured to generate an alternating electric field; the sensor group comprises a temperature sensor for monitoring the environment temperature, a humidity sensor for monitoring the relative humidity of the environment and an electric field intensity sensor for monitoring the actual intensity of the alternating electric field; the signal input end of the embedded control unit is electrically connected with the driving circuit of the intelligent electric field generator and the sensor group, and the control output end of the embedded control unit is electrically connected with the intelligent electric field generator. Closed-loop control is formed by comparing the actual and target electric field intensities in real time and dynamically adjusting the voltage, it is ensured that the electric field in the cavity stably approaches the target value, the situation that the fresh-keeping effect is affected by electric field fluctuation is avoided, and the quality guarantee period of livestock and poultry meat is remarkably prolonged.
