Problems solved by technology

Postharvest physiological problems such as respiratory metabolism type, physiological characteristics of maturity and aging, tolerance to cold storage temperature and other postharvest physiological problems of Lianwu fruit have not been reported. , cannot effectively prevent the flocculent and soft phenomenon of the lotus mist fruit after harvest
[0005] The Chinese patent application with the publication number CN 103493880 A provides a fresh-keeping method for lotus mist. The formula of the fresh-keeping agent is: chitosan 16%, γ-aminobutyric acid 0.3%, calcium lactate 1.5%, food grade glycerin 4 %, distilled water 78.2%; however, the lotus mist preservative needs to be used in combination with heat stress, which requires strict temperature conditions and complicated operation steps. The pulp structure of lotus mist fruit is loose, and the quality and flavor of the fruit will be affected after heat shock treatment

Abstract

The invention belongs to the technical field of fruit fresh preservation, and in particular relates to a preservative for preventing a picked syzygium samarangense fruit from flocculence and softness and a fresh preservation method. The preservative comprises the following components: 30-500mumol.L<-1> of sodium nitroprusside, 0.5-20mumol.L<-1> of heteroauxin, 50-250mumol.L<-1> of gibberellin and 50-100 mumol.L<-1> of 6-benzyladenine. A method for performing fresh preservation on the syzygium samarangense fruit comprises the steps of placing the picked syzygium samarangense fruit in a container, injecting the preservative, and immersing the picked syzygium samarangense fruit into the preservative solution for 3-20min. The preservative can effectively prevents the picked syzygium samarangense fruit from flocculence and softness, keeps fruit hardness, prevents fruit rotting, prolongs the shelf life of the syzygium samarangense and improves the commercial value of the syzygium samarangense fruit.

Description

technical field [0001] The invention belongs to the technical field of fruit fresh-keeping, and in particular relates to a fresh-keeping agent and a fresh-keeping method for preventing post-harvest lotus mist fruit from flocculent and soft. Background technique [0002] wax apple( Syzygium samarangense Merr. et Perry) is also known as foreign apple, sweet mist, Java apple, etc. It is native to the Malay Peninsula, Indonesia and the Andaman Islands, and is widely cultivated in Malaysia, Indonesia and the Philippines. It is one of the important and rare fruit trees newly developed in tropical and subtropical regions in recent years. Lotus mist was introduced to Taiwan in the 17th century, and it was only cultivated sporadically in the early days. In the 1970s and 1980s, due to the improvement of varieties and cultivation techniques, the cultivation area increased significantly, and it became an important economic fruit tree in Taiwan. Taiwan's lotus mist cultivation area r...
