But from the 4th day, the effect of ice treatment gradually decreases, and the physiological quality drops significantly, which shows that this method is not suitable for transportation with longer distances and longer time (Li Xiang et al., the impact of cowpea storage and transportation packaging methods in Hainan Province on the quality of cowpea after harvesting Impact, Tropical Agricultural Science, 2011,31(5):76-78)
Xie Xiaona et al. discussed the effect of hot water treatment on the storage and preservation of cowpea (Xie Xiaona et al., Effect of hot water treatment on the storage quality of cowpea, Guangdong Agricultural Science, 2011, 1:104-107). Production application is limited

Embodiment 1

[0024] 1. Material: Cowpea (Vigna sesquipedalis) is collected from Hepu, Guangxi, and the variety is You Cow No. 1. 40-50 pods / bunch, transported to the Postharvest Biology Laboratory of South China Botanical Garden, Chinese Academy of Sciences in a foam box with ice on the day of picking, and then carried out the following fresh-keeping treatment.

[0025] 2. Treatment method: Select the cowpea fruit harvested when the tender pods are fully developed 10-15 days after flowering, the pods are full, crisp and tender, the pods are uniform in thickness, and the pods change from dark green to light green and slightly shiny. Sorting is carried out in order to remove diseased and pest fruits and defective fruits, so as to obtain cowpea pods without mechanical damage and disease and insect pests. The control and treatment fruits were soaked with clear water and freshly prepared AP (apple polyphenol) aqueous solutions of different concentrations (AP was dissolved in water, the specific...

Embodiment 2

[0038] Material: Cowpea (Vigna sesquipedalis) is collected from Hepu area, Guangxi, and the variety is You Cow No.1.

[0039] Processing method: freshly harvested cowpea 10-15 days after flowering on a sunny day, when the tender pods are fully developed, the pods are full, crisp and tender, the pods are uniform in thickness, and the pods change from dark green to light green and slightly shiny. Cowpea fruits are sorted to remove diseased and defective fruits and defective fruits to obtain cowpea pods without mechanical damage and pests. Control and treatment pods were soaked in water and freshly prepared AP aqueous solution with a mass fraction of 0.05% (dissolve 0.05g of AP in 100ml of water) for 10 minutes, take out the AP aqueous solution on the surface of the fruit and dry it, and cover it with a 0.01mm thick Packed in polyethylene film bags, 40-50 pods / bag, 5-6 bags per treatment, stored at 25°C for 6 days. Compared with the control, after being treated with 0.05% AP aqu...

Embodiment 3

[0041] Material: Cowpea (Vigna sesquipedalis) is collected from Hepu area, Guangxi, and the variety is "You Cow No. 1".

[0042] Processing method: Freshly harvest cowpea 10-15 days after flowering on a sunny day. The tender pods are fully developed, the pods are full, crisp and tender, the pods are uniform in thickness, and the pods change from dark green to light green. Sorting is carried out to remove diseases and insect pests Fruit, defective fruit, to obtain cowpea pods without mechanical damage and pests and diseases. The control and treatment fruits were soaked with clear water and freshly prepared 5% AP aqueous solution (dissolving 5g of AP in 100ml of water) for 0.5min respectively, and after the AP aqueous solution on the surface of the fruit was taken out and dried, it was soaked with a 0.03mm thick Packed in polyethylene film bags, 40-50 pods / bag, 5-6 bags per treatment, stored at 25°C for 6 days.

[0043] Compared with the control, after being treated with 5% AP ...

Abstract

The invention discloses a vigna sesquipedalis color-protecting and fresh-keeping method including the following steps: choosing vigna sesquipedalis pods which are harvested in a sunny day after 10-15 days after flowering and have no mechanical damage and no diseases and insect pests; soaking the vigna sesquipedalis pods in a vigna sesquipedalis fresh-keeping solution for 0.5-10 min, taking out, after the vigna sesquipedalis fresh-keeping solution on the fruit surface is air-dried, packing with fresh-keeping bags, and storing, wherein the vigna sesquipedalis fresh-keeping solution is an apple polyphenol aqueous solution with the mass fraction of 0.05-5%. After the vigna sesquipedalis pods are treated by the vigna sesquipedalis color-protecting and fresh-keeping method, the vigna sesquipedalis commodity rate can be improved by 15-69%.

Description

Technical field: [0001] The invention belongs to the field of fresh-keeping of fruits and vegetables, and in particular relates to a color-preserving and fresh-keeping method of cowpea. Background technique: [0002] Cowpea (Vigna sesquipedalis) is also known as long pod bean, long bean carob, pink bean and so on. It is an annual twining herbaceous plant of the genus Vigna in the family Papilionaceae. It is native to south-central Asia, including China, Southeast Asia, and India. It has been cultivated in my country since ancient times. It is a widely planted legume vegetable crop in my country. It is widely cultivated in various provinces and regions in China, and it is more cultivated in central and southern provinces and cities. Cowpea is rich in nutrition, rich in protein, carbohydrates, multivitamins and mineral elements, and has high economic value. Cowpea can be fried, eaten cold or marinated, and the mature beans can be used as grain, which is very popular among co...
