Volatile preservative for potato wedges

Abstract

The invention belongs to the field of commercial crops storage, and provides volatile preservative for potato wedges, which comprises, in mass percentage, 20-80% of volatile strong oxidant, 0-0.1% of sodium dodecyl sulfate and the balance of water. The strong oxidant in the preservative can volatilize to a certain concentration in a closed space so as to achieve corrosion prevention. Compared with soaking preservatives, the volatile preservative is washing-free, labor-reducing and more convenient to use. The volatile preservative has an evident inhibitory effect to potato dry rot and soft rot. The preservative respectively reaches 0.56ug / ml and 0.24ug / ml and has 100% of relative inhibitory rate for dry rot and soft rot. Compared with pesticide type preservatives, the volatile preservative is higher in safety.

Description

technical field [0001] The invention belongs to the field of economic crop storage, and in particular relates to a volatile potato block preservative. Background technique [0002] In recent years, with the continuous increase of potato storage, the problem of potato rot during storage has become increasingly prominent, and the damage of storage diseases to potatoes has increased year by year. According to statistics, the annual loss due to tuber dry rot and soft rot reaches an average of 6-10%, sometimes even as high as 60%, but the corresponding antiseptic and sterilization measures are still far behind. The main reasons are as follows: 1) The storage conditions (mainly referring to the facilities) are not perfect, and there is no basis for prevention and control; 2) Most of the antiseptics and fungicides used in production are pesticides, and the scope of use is limited due to safety; 3) The researched and developed antiseptics Most of them are liquid-soaked potato cubes...
