Embodiment 1

[0035] On the basis of determining the detection index, means and establishing the maturity classification standard, the specific steps of embodiment 1 measuring the maturity of kiwi fruit are as follows:

[0036] Harvesting and selection: Pick fruits at random 78 days after the full flowering stage, transport them back to the laboratory immediately after harvesting, store them at low temperature, and remove the fruits with diseases, insect pests and mechanical damage, and select kiwifruit with uniform size and regular fruit shape for later use.

[0037] Maturity-related index measurement: Measure the basic indicators of the selected kiwifruit on the same day, including fruit firmness, soluble solids, titratable acid, starch, tannin and fruit seed color change index, and repeat 3 times.

[0038] Determining the maturity of kiwi fruit:

[0039] The average of the results of the three maturity-related indicators of the tested samples is:

[0040] Hardness: 18kg / cm 2 ; Soluble ...

Embodiment 2

[0045] The concrete steps that embodiment 2 measures the maturity of Actinidia jujube is:

[0046] Harvesting and selection: Pick fruits at random 92 days after the full flowering stage, transport them back to the laboratory immediately after harvesting, store them at low temperature, remove the fruits of diseases, insect pests and mechanical damage, and select kiwifruit of uniform size for later use.

[0047] Maturity-related index measurement: Measure the basic indexes of the selected kiwifruit on the same day, including fruit firmness, soluble solids, titratable acid, vitamin C, tannin and fruit seed color change index, and repeat 3 times.

[0048] Determining the maturity of kiwi fruit:

[0049] The average results of the three maturity-related indicators of the tested samples are:

[0050] Hardness: 12kg / cm 2 ; Soluble solids: 10%; Titratable acid: 0.46%; Starch: 0.80%; Tannin: 0.039%.

[0051] The colors of the 30 fruit seeds are: 10 for level 2, 20 for level 3,

Abstract

The invention provides a method for detecting the maturity of actinidia arguta. The method comprises the steps of from 70-97 days after full-bloom stage, picking fruits optionally every day, measuring the basic indexes of the picked actinidia arguta in the same day, detecting the six physiological and biochemical indexes including fruit hardness, soluble solid, titratable acid, starch, tannin and fruit and seed degreening index, and correspondingly establishing four classification standards of the maturity; measuring classification standard maturity ranges of the four or more physiological and biochemical indexes of the sample to confirm grade of maturity of the fruits of the sample. After the method is adopted, the maturity of the actinidia arguta can be effectively detected, so that the best picking times of the actinidia arguta with different selling demands can be confirmed, the freshness, the color, the aroma and the taste of the fruits can be guaranteed in the subsequent storage or processing process, the demands of the market and the business can be well met, the economical benefit is increased, and powerful technical support is provided for the actinidia arguta industry.

Description

technical field [0001] The invention belongs to the technical field of fruit maturity detection and classification, and in particular relates to a detection method for the maturity of kiwi fruit. Background technique [0002] There are abundant resources of kiwi fruit in China. Its fruit is smooth and hairless, delicious, easy to eat and process, and rich in vitamin C, polyphenols and minerals. Actinidia kiwifruit is one of the high-quality wild fruit varieties that have been studied in recent years. It has been highly valued by the relevant departments of the state, and it has gradually developed from wild resources to artificial cultivation. At the same time, many excellent new varieties have been cultivated. [0003] However, the storage life and shelf life of Actinidia jujube fruit are short, which restricts the research on its characteristics and the industrial development of product processing. The harvest period of fruit directly affects the storage life and fruit qu...
