Embodiment 1

[0025] The fresh-keeping effects of compounds pencolide, carboxymethyl chitosan and salicylic acid on litchi were investigated respectively.

[0026] Experimental method: the compound pencolide was formulated into an aqueous solution with a concentration of 0.2 g / L, and carboxymethyl chitosan and salicylic acid were respectively used as positive controls, and the carboxymethyl chitosan was formulated into an aqueous solution with a mass concentration of 2%. Salicylic acid was formulated into a solution with a concentration of 0.3 g / L (dissolved salicylic acid in an appropriate amount of DMSO, and then uniformly dispersed in water to prepare), and pure water was used as a blank control. Randomly select 35-40 lychees from the Zengcheng base as experimental materials, soak the lychees in the corresponding solution for about 10 minutes, then fish them out and put them in the laboratory for indoor observation. After 8 days, visually inspect the amount of rot and take pictures as ex...

Embodiment 2

[0028] The fresh-keeping effects of compounds pencolide, carboxymethyl chitosan and salicylic acid on tomatoes were investigated respectively.

[0029] Experimental method: the compound pencolide was formulated into an aqueous solution with a concentration of 0.2 g / L, and carboxymethyl chitosan and salicylic acid were respectively used as positive controls, and the carboxymethyl chitosan was formulated into an aqueous solution with a mass concentration of 2%. Salicylic acid was prepared into a solution with a concentration of 0.3 g / L, and pure water was used as a blank control. Tomatoes with a weight of 810-830g were randomly selected as experimental materials, and the tomatoes were soaked in the corresponding solution for about 10 minutes, then fished out, placed in the laboratory, and observed indoors. After 15 days, visually inspect the amount of rot and take pictures as experimental records. see results image 3 and 4 . Depend on image 3 and 4 It can be seen that us...

Embodiment 3

[0031] The fresh-keeping effects of compounds pencolide, carboxymethyl chitosan and salicylic acid on capsicum were investigated respectively.

[0032] Experimental method: the compound pencolide was formulated into an aqueous solution with a concentration of 0.2 g / L, and carboxymethyl chitosan and salicylic acid were respectively used as positive controls, and the carboxymethyl chitosan was formulated into an aqueous solution with a mass concentration of 2%. Salicylic acid was prepared into a solution with a concentration of 0.3 g / L, and pure water was used as a blank control. Randomly select peppers with a weight of 400-412g as experimental materials, soak the peppers in the corresponding solution for about 10 minutes, then fish them out and put them in the laboratory for indoor observation. After 23 days, visually inspect the amount of rot and take pictures as experimental records. see results Figure 5 and 6 . Depend on Figure 5 and 6 It can be seen that using the c...

Abstract

The invention discloses an application of a compound pencolide in the preparation of a preservative. The compound pencolide can obviously prolong the shelf life of fruits and vegetables, at the same time, prominently reduces the bad fruit rate or corruption degree, has a better fresh keeping effect, compared with that of carboxymethyl chitosan or salicylic acid, is safe and nontoxic, can be used as a preservative to prolong the shelf life of food such as fruits, vegetables, meat, seafood, and the like, and is capable of reducing the storage loss.

Description

technical field [0001] The invention relates to the field of preservation of agricultural products, in particular to the application of the compound pencolide in the preparation of preservatives. Background technique [0002] my country is the largest producer of fruits in the world. Due to the wide variety of fruits, which are seasonally harvested and concentrated on the market, the technology of fruit preservation is limited, resulting in a high rate of post-harvest fruit decay and huge economic losses. The water content of vegetables is high, so they are easy to spoil and deteriorate after harvesting, shortening the storage period, seriously affecting their nutritional value and commodity value. Currently commonly used fresh-keeping methods are: low-temperature refrigeration method, controlled atmosphere method, radiation preservation method and chemical preservation method. The first three storage and fresh-keeping methods consume a lot of energy, have high equipment co...
