Embodiment 1

[0077] A post-harvest storage and preservation method for crystal grapes at normal temperature, select 9 mature crystal grapes; weigh 0.10mmol / L salicylic acid, 0.10mmol / L sodium nitroprusside and 100mmol / L calcium chloride according to molar concentration , dissolved in distilled water; the prepared salicylic acid solution, sodium nitroprusside solution and calcium chloride solution were mixed to prepare a preservative; the prepared salicylic acid solution, sodium nitroprusside solution and calcium chloride solution were mixed to prepare a preservative Antistaling agent; soak the selected crystal grape ears in the aqueous preservative solution for 60 minutes. After soaking, take out the ears, place them in a ventilated place, and dry the surface moisture of the fruit; put the fruit into a special white paper bag for grapes after drying. Tighten the mouth of the bag, and place it flat in plastic fruit baskets with a length of 40cm, a width of 30cm, and a height of 20cm, and pla...

Embodiment 2

[0079] Select 9.5 mature crystal grapes; weigh 0.05mmol / L salicylic acid according to the molar concentration, 0.05mmol / L sodium nitroprusside and 50mmol / L calcium chloride, dissolve with distilled water; prepare salicylic acid solution , sodium nitroprusside solution and calcium chloride solution are mixed to prepare a preservative; the selected crystal grape ears are placed in the aqueous preservative solution and soaked for 120 minutes. After soaking, take out the fruit ears, place them in a ventilated place, and dry the fruit surface Moisture; after the fruit is dried, put it into a special white paper bag for grapes, tie the mouth of the bag tightly, and place it flat in a plastic fruit basket with a length of 40cm, a width of 30cm, and a height of 20cm, and place two layers in each basket; put the plastic basket full of grapes Move into a cool airtight room and stack together, keep room temperature 22 ℃, relative humidity 87% and store for 45 days.

Embodiment 3

[0081] Select 10 ripe crystal grapes; weigh 0.20mmol / L salicylic acid according to molar concentration, 0.20mmol / L sodium nitroprusside and 200mmol / L calcium chloride, dissolve with distilled water; prepare salicylic acid solution , sodium nitroprusside solution and calcium chloride solution are mixed to prepare a preservative; the selected crystal grape ears are placed in the aqueous preservative solution and soaked for 30 minutes. After soaking, take out the fruit ears, place them in a ventilated place, and dry the fruit surface Moisture; after the fruit is dried, put it into a special white paper bag for grapes, tie the mouth of the bag tightly, and place it flat in a plastic fruit basket with a length of 40cm, a width of 30cm, and a height of 20cm, and place two layers in each basket; put the plastic basket full of grapes Move into a cool airtight room and stack together, keep room temperature 25 ℃, relative humidity 90% and store for 30 days.

Abstract

The present invention discloses a preservative for storing postharvest crystal grapes at room temperature and a preservation method thereof. The preservative comprises the following components in molar concentrations: salicylic acid 0.05-0.20 mmol/L, sodium nitroprusside 0.05-0.20 mmol/L and calcium chloride 50-200 mmol/L. Specifically, the preservation method includes fresh fruit selection, preservative preparation, preservation treatment and medicament treatment. The preservative and preservation method can significantly slower the decline rate of fruit nutrient substances and peel pigment substances, and the fruit nutrient substances can be still maintained at a high level after 2 months of storage.

Description

technical field [0001] The invention belongs to the technical field of post-harvest storage and fresh-keeping of fruits and vegetables, in particular to a post-harvest storage and fresh-keeping agent for crystal grapes at normal temperature, and also relates to a post-harvest storage and fresh-keeping method for crystal grapes at normal temperature. Background technique [0002] Crystal Grape is a European and American hybrid variety with unknown parents. It is widely loved by consumers because of its early maturity, strong fruit aroma and excellent taste. This variety is currently mainly planted in the Yunnan-Guizhou Plateau. It has strong resistance to biotic and abiotic stress, wide adaptability, and stable yield. It occupies an important position in the grape planting industry in the Yunnan-Guizhou Plateau. Because crystal grapes have the characteristics of solute fruit texture, extremely soft and juicy fruit after ripening, easy to break, easy to fall off after harvesti...
