Tender corn is a hot food on the market and has great potential for development. How to make the sweet and fragrant tender corn supply to the market all the year round? At present, the methods of keeping fresh corn are low-temperature quick-freezing, fresh-keeping, vacuum preservation, normal temperature preservation and internationally advanced G060y-radiation preservation. Some fresh-keeping methods have large investment and are not suitable for the majority of farmers. So, how to keep fresh corn under ordinary conditions?
Preserved fresh-keeping ordinary corn should be a variety with a long growing period. The longer the growth period, the better the quality. The best taste of corn is sticky corn, black corn and waxy corn.
The timing of picking fresh corn must be in the milk ripening period, that is, the corn kernels have been full and the ears are not dried before the ears. After the corn cob is peeled off, it is preferable to use a finger to pry the bottom grain to have a slurry flowing out.
Preservation method Prepare an iron pan and inject half a pot of water, heat to not less than 80 ° C, add the storage agent according to the ratio of water: 250:1, corn ear should be impregnated with corn storage agent as soon as possible after picking. When the color of the corn is bright (about 3 minutes), drain the water in time, and dry it manually or naturally to remove the free water in the ear to inhibit the growth of the mold. After drying, it can be stored in normal room at room temperature.
Preservation conditions The storage requirements for storage of tender corn at room temperature are not strict. There should be no direct sunlight in the room to prevent decomposition of protein. In wet areas, lime powder should be sprinkled on the ground or plastic cloth should be used to prevent moisture. Because of the special aroma of tender corn ears, it is necessary to do a good job in preventing rodents. When stored, it can be stacked in baskets or plastic woven bags. If it needs to be eaten or sold, it can be used as needed. After washing and soaking in hot water, it can be re-freshed. The freshly harvested corn ear is exactly the same in appearance, color and tenderness as freshly picked fresh corn.
Normal temperature preservation not only saves money for building a low temperature warehouse, but also does not require a vacuum machine. And in the autumn storage, winter and spring sales, can receive very good benefits.
