Problems solved by technology

Since it takes 3 to 4 days from transportation to shelf sale, the long-distance and long-term transportation makes table grapes very prone to shattering, wilting and dehydration of the cobs and fruit grains, and discoloration of the fruit surface during the transportation and sales process; Cut flowers also often lose water and color due to the dry climate in Xinjiang, resulting in a short shelf life and poor product appearance, which affects market competitiveness and economic benefits

Embodiment 1

[0032] Example 1. The antistaling agent for prolonging the shelf life of grapes or fresh cut flowers. The raw materials include water, sucrose, pectin, hydrophilic resin, abscisic acid (ABA), gibberellin (GA) and plant antibacterial agents; Each liter of water contains 50 g to 100 g sucrose, 20 g to 30 g pectin, 5 g to 30 g hydrophilic resin, 10 mg to 30 mg abscisic acid (ABA), 20 mg to 40 mg gibberellin (GA) , 30 mg to 100 mg of plant antibacterial agent.

Embodiment 2

[0033] Example 2, the preservative for prolonging the shelf life of grapes or fresh cut flowers, the raw materials include water, sucrose, pectin, hydrophilic resin, abscisic acid (ABA), gibberellin (GA) and plant antibacterial agents; Each liter of water contains 50g or 100g sucrose, 20g or 30g pectin, 5g or 30g hydrophilic resin, 10mg or 30mg abscisic acid (ABA), 20mg or 40mg gibberellin (GA) , 30 mg or 100 mg of plant antibacterial agent.

Embodiment 3

[0034] In Example 3, the antistaling agent for prolonging the shelf life of grapes or fresh cut flowers was obtained by the following preparation method: dissolving the required amount of sucrose in the required amount of water to form a sucrose solution, and adding the required amount of gibberellin (GA ) After dissolving in ethanol, the gibberellin (GA) mother liquor is obtained. In the sucrose solution, add the required amount of abscisic acid (ABA), gibberellin (GA) mother liquor, plant antibacterial agent, hydrophilic resin and pectin and mix well , Sterilized by a high-pressure steam sterilizer, sterilization pressure is 0.12MPa to 0.15MPa, sterilization temperature is 120°C to 126°C, and sterilization time is 15 minutes to 30 minutes. After sterilization, a jelly-like extended grape or Preservative for the shelf life of fresh cut flowers. Dissolve the required amount of gibberellin (GA) with minimal ethanol to obtain the gibberellin (GA) mother liquor.

Abstract

The invention relates to the technical field of preservatives, in particular to a preservative for prolonging the shelf life of grapes or fresh cut flowers and a preparation method and a use method thereof. Raw materials include water, cane sugar, pectin, hydrophilic resin, abscisic acid, gibberellin and a plant antibacterial agent. The preservative for prolonging the shelf life of grapes or fresh cut flowers has a good fresh-keeping effect, can prolong the shelf life of table grapes by 3-5 days, and can prolong the flowering phase of the fresh cut flowers by 2-3 days compared with in-vitro fresh flowers; meanwhile, a portable capsule-shaped fresh-keeping bottle can be conveniently arranged on fresh grape stems or fresh cut flower branches, and the preservative for prolonging the shelf life of grapes or fresh cut flowers is in a jelly form, so that the preservative for prolonging the shelf life of grapes or fresh cut flowers does not leak no matter how the portable capsule-shaped fresh-keeping bottle is placed during transportation. The preservative for prolonging the shelf life of grapes or fresh cut flowers can replenish moisture and nutrition for fresh grapes or fresh cut flowers without causing waste.

Description

Technical field [0001] The invention relates to the technical field of preservatives, and is a preservative for extending the shelf life of grapes or fresh cut flowers, and a preparation method and use method thereof. Background technique [0002] Due to the characteristics of less rainy weather, sufficient sunlight, dry climate, and less occurrence of crop diseases and insect pests, Xinjiang has the unique natural advantage of producing high-quality and safe table grapes. This is unmatched by other provinces and regions in China. The grapes produced in China have very good characteristics. Strong market competitiveness. Xinjiang is the country's largest grape-producing area, with an area and output of 24.11% and 23.05% of the country's total respectively. The grapes produced in Xinjiang are not only sold well in the domestic, Hong Kong, and Macao markets, but also have a high reputation in the international market. At the same time, Xinjiang is also the country's largest green...
