Abstract

The invention discloses a method for synthetic preservation of waxberry by using a plant extract. The method comprises the following steps of: selecting waxberry fruits which are harvested on sunny days, are of mature of 80% and have no mechanical damages or plant diseases and insect pests, and performing pre-cooling treatment on the waxberry; uniformly spraying an ethanol solution of a mixture of salicylic acid and citral on the surfaces of the waxberry fruits, wherein the concentration of the ethanol solution of each of the salicylic acid and the citral is 500 and 1000 mu mol/L respectively, and 10mL of the ethanol solution of the salicylic acid and the citral is used per kg of the waxberry fruits; then placing the waxberry fruits in plastic boxes with holes with 9-10 waxberry fruits in each box; storing in an environment of 1 plus or minus 1 DEG C for 30 days; and then transferring into the environment of 20 plus or minus 1 DEG C, and placing for 2 days as shelf life. By adopting the method disclosed by the invention for storage and preservation of the waxberry fruits, the fruits can still keep good appearance and higher quality after being stored at low temperature for 30 days, the healthy fruit rate is above 90%, and the healthy fruit rate can be kept above 75% after 2-day normal temperature (20 plus or minus 1 DEG C) shelf life.

Description

[0001] technical field [0002] The invention belongs to a fruit storage method, and relates to a storage and fresh-keeping method for horticultural products, in particular to a method for comprehensively keeping fresh red bayberry by using plant extracts from bayberry fruit. [0003] Background technique [0004] Bayberry ( Myrica Rubra L. Zucc.) belongs to Myricaceae Myrica genus, which is a specialty fruit in my country. It is mainly distributed in Zhejiang, Fujian, Jiangsu, Jiangxi and other provinces. Among them, Zhejiang Province has the most varieties and the best quality. Red bayberry fruit is bright in color, sweet and sour, and has high nutritional value and health value. In addition, the harvest period coincides with the off-season of fruit, and is favored by consumers. [0005] However, the maturity of bayberry is mainly concentrated in the middle and late June for more than ten days, which coincides with the high-temperature and high-humidity rainy season. In...
