The application discloses a preservative for inhibiting browning of fresh walnut kernels and an application method, relates to the technical field of food preservation, and is characterized in that the preservative is composed of a disinfectant, an antioxidant and a stabilizer according to a weight ratio of 1:(600-800):(8-12), wherein the disinfectant is a chlorine dioxide powder, the antioxidant is a tert-butyl hydroquinone powder, and the stabilizer is a mixture of sodium carbonate, sodium bicarbonate and citric acid. The preparation method comprises the following steps: mixing the components to prepare tablets or powders. When applied, the preservative is dissolved in water at a ratio of 1:5000 to 1:10000 to prepare a preservative solution, fresh walnut kernels are soaked in the preservative solution for 5-20 minutes, and then the fresh walnut kernels are drained and packaged. Through the synergistic effect of ClO2 and TBHQ, the two problems of microbial corruption and enzymatic browning of fresh walnut kernels are solved efficiently, the shelf life is significantly prolonged, the method is safe, simple, low in cost and suitable for industrial production.

Fumigation chamber (1) for products to be treated, comprising sealed walls (2) with a loading opening, a fumigation cycle control module (10), a sealed door (3), a heater (4), a system (5) for detecting and relieving any overpressure inside the chamber, and a degassing circuit (6) for expelling the fume gas from the chamber and replacing it with external air. FIGURE 1

It sterilizes all granular materials evenly and completes the sterilization process in a short amount of time. [Solution] The sterilization device 10 comprises a tank 11 for containing granular material to be sterilized, and a gas supply device 12 for supplying chlorine dioxide gas to the inside of the tank 11 from below. The gas supply device 12 sterilizes the granular material inside the tank 11 while causing it to flow by blowing out chlorine dioxide gas.

The application provides a preparation method of stir-fried gualouzi with improved storage quality based on a leaf extract of Bacopa monnieri, and relates to the field of food. The preparation method comprises the steps of steam pretreatment, microwave enzyme inactivation, composite antioxidant treatment, stir-frying, cooling and vacuum deoxygenation packaging. The application adopts a comprehensive preservation method, which comprises three means of steam-microwave enzyme inactivation, smearing of natural antioxidants and vacuum deoxygenation packaging, and establishes a multiple protection system from enzyme activity inhibition, oxidation reaction blocking to external oxygen isolation, thereby establishing a comprehensive quality protection measure for the stir-fried gualouzi product. Through the above three means, which are connected and supplemented to each other, the shelf life of the product is significantly prolonged on the basis of ensuring food safety, and the storage quality is effectively improved. The application breaks through the limitation of a single preservation method, provides an effective solution for prolonging the shelf life of stir-fried gualouzi and maintaining the flavor and nutritional value thereof, and has important popularization and application value.
