[0013] 1. Preparation of False Betel Extract

[0014] The preparation method of the extract of the betel is as follows: wash the whole plant of betel, dry it in the shade, pulverize it with a pulverizer, and pass through a 60-mesh sieve to obtain a pulverized product; add 8 times the amount of 95% ethanol to the obtained pulverized product, and soak it at room temperature for 24 hours , extracted with ultrasound for 35min, then filtered with a Buchner funnel, and collected the filtrate; extracted 3 times in the same way, combined all the filtrates, then concentrated the filtrate under reduced pressure with a rotary evaporator to a paste with a relative density of 1.15, and then freeze-dried into powder, that is, to obtain the extract of the betel.

[0015] 2. Indoor toxicity test

[0016] Test object: mango anthracnose fungus Colletotrichum gloeosporioides Penz.

[0017] Test method: After pre-testing to determine the effective inhibitory concentration range of the betel ext...

Abstract

The invention relates to a preservative containing piper sarmentosum extract and prochloraz. The active constituents of the fresh-keeping agent consist of the piper sarmentosum extract and the prochloraz, wherein the weight ratio of the piper sarmentosum extract to the prochloraz is 1:(0.3-5). According to the invention, the effects of the preservative are remarkable as the active constituents work together to improve the effects and the mix of the active constituents can reduce the consumption amount of a single constituent. The preservative can effectively reduce the anthracnose morbidity of harvested fruits and extends fruit shelf life. According to the invention, a preparation process is simple and the preservative has low production cost, has high effectiveness and safety, has no impact on food flavors and meets the requirement of green environmental protection of fruit and vegetable preservation.

Description

technical field [0001] The invention relates to the technical field of fresh-keeping of fruits and vegetables, in particular to a fresh-keeping agent containing a betel extract and prochloraz. Background technique [0002] False sarmentosum (scientific name: Piper sarmentosum Roxb.), also known as clam, false sarmentosum, mountain sarmentosum, etc., is a plant of the genus Piper in the family Piperaceae. False betel is produced in Guangdong, Guangxi, Fujian, Yunnan, Guizhou and Tibet (Medog) provinces and regions in China, and is born in the forest or on the wetland next to the village. False betel is pungent in taste, warm in nature, and non-toxic. It can be used medicinally to cure rheumatic bone pain, bruises, wind-cold cough, pregnancy and postpartum edema, etc. It can also be eaten. People often use its leaves to cook. Its delicacy is often compared with perilla. The water extract of pseudobenny stem and leaf has inhibitory effect on Staphylococcus aureus and Shigella...
