Fresh storage method of tender peanuts at room temperature
Sep 12,2023
Fresh and tender peanuts are one of the most difficult agricultural products to store at room temperature. Currently, there are two mature and feasible ways to preserve them at home and abroad. One is to use low-temperature quick freezing in cold storage, and the other is to use vacuum packaging after pre cooking. The former has a large investment, while the latter has a cumbersome process, which is not suitable for the simple and feasible product processing of peanut production areas in China. The method of using preservatives to assist in sand storage and preservation invented by farmers in western Shandong in practice, Undoubtedly, a new way has been found to increase the income of farmers' peanuts.
Preparation of preservatives: Following the principles of green and pollution-free agricultural product production and sales, it is recommended to use a 0.5% glycan aqueous solution as the preservative. Glycoglycan is a white crystalline powder made from edible plants such as sweet potato and seaweed through acid hydrolysis. Its aqueous solution has various effects such as insect prevention and preservation, which can effectively extend the shelf life of fruit and vegetable products at room temperature. Dissolve glycan in water and prepare a 5% aqueous solution. When using, add boiling water to prepare a 0.5% aqueous solution.
Freshness preservation treatment: Mix the dried fine sand with a 0.5% glycan aqueous solution to achieve a moisture content of 30-40%. After removing the seedlings and roots of freshly unearthed fresh peanuts, the peanuts are stored with soil in a ratio of 1 cubic meter of fine sand per 0.5 mu of product, layer by layer, without the need for manual management such as temperature and humidity control.
