Green fresh-keeping sweet potato storage method

Abstract

The invention discloses a green fresh-keeping sweet potato storage method, and particularly relates to a sweet potato storage method. The sweet potato storage method comprises the steps that mixed forage is used for smudging the interior of a sweet potato storage chamber for 60-80 min; after smudging is completed, a potassium permanganate solution with the concentration of 0.1 mol/L is sprayed onthe side walls, ground and top in the storage chamber; after spraying, the sweet potato storage chamber is tightly closed, and the closed state lasts for 100-120 min; the peripheral wall and ground ofthe sweet potato storage chamber are coated with photocatalyst, a light is turned on, irradiation lasts for 20-30 h, and at the time, pretreatment of the sweet potato storage chamber is completed; after being put in baskets, the sweet potatoes are placed in the pretreated sweet potato storage chamber for high-temperature healing treatment, and ventilation is kept during the period; after the high-temperature healing treatment is completed, the temperature in the sweet potato storage chamber is controlled to be 10-13 DEG C, the relative humidity is 80-90%, and ventilation is kept during the sweet potato storage period. The method has the advantages that the fresh-keeping storage time of sweet potatoes can be prolonged, and the operation is convenient.

AI Technical Summary

Benefits of technology

This patented technology helps prevent diseases caused by harmful microorganisms from infecting crops during harvesting processes. By applying special coatings on certain parts inside the store where saffron grains grow, they become less likely to be affected due to germination. Additionally, this process promotes faster dryness that reduces damage when storing them at higher temperatures without compromising their quality. Overall, these technical improvements help keep food fresh longer while reducing spoiling issues such as bacterial growth.

Problems solved by technology

This patented technical solution involves creating an effective system for storing and preserving sweets without causing harmful bacteria on consumable products like breads during long periods after production.
