Fresh food sweet corn frozen processing technology

Quick-frozen sweet Waxy Corn maintains the shape, color, flavor, and nutrient content of the original Fresh Corn, and can be supplied to the market throughout the year, and is favored by people. It can be eaten directly, or it can be made into a flavor corn soup, which becomes a delicacy on the table of hotels, restaurants and families. Based on the comprehensive development and utilization of corn resources and the needs of foreign exchange earning agriculture, we started the selection and breeding of fresh sweet waxy corn varieties in 1991. Fresh-keeping processing technologies such as quick-freeze vacuum packaging and development and application of processed products. At present, the new variety of corn and fruit that is selected for breeding, Xianjing No. 1, and its processed products are highly favored by the production and consumers. Over the past few years, significant economic and social benefits have been achieved through planting, processing, and production. Processing Technology: Appropriate picking → peeling → dehairing → washing → inspection → removing impurities → precooking → cooling → bagging → freezing → cryogenic storage. (I) It is very important to adopt proper harvesting in suitable period. Different varieties have different harvesting periods, and the same variety has different harvesting time, and its quality is very different. Fresh medlar No. 1 was harvested for 22 to 24 days after pollination. The harvested ears should be processed in time and must be completed within 10 hours from the processing of the harvest. Harvested. Skinning, hair removal, and washing are all done manually to prevent damage to the grains. After washing, we must remove granules, worms, untidy tops, and too tender and too old ears. (b) Precooking should be boiled for 25-30 minutes. The cold spot temperature should be above 90°C. When cooking, all the ears should be immersed in water. This will make them easier to cook. Cooking affects grain tightness, luster, and quality. (3) Cooling after precooking remove and cool rapidly. Rinse with 10°C cold water for 10 minutes so that the center temperature of the ear rapidly drops below 25°C. After lifting it, put it on a wire mesh and dry it with an electric fan ( About half an hour) to prevent frost on the grain surface during quick-freezing. (D) Package The dried corn ear is packed into a plastic composite film bag and sealed with a sealer. (e) Freezing in a freezer, the temperature is below -35°C (8 to 10 hours); the freezer is under minus 45°C for 30 to 45 minutes. (6) Cryopreservation After quick-frozen, the ears are packaged, transferred to a cold storage at minus 18°C, and stored with the sale.
