Embodiment 1

[0026] A method for selecting foreign matter in blueberries, comprising the steps of:

[0027] (1) Add white granulated sugar and water with a mass ratio of 1:6 in the open sandwich pot;

[0028] (2) The temperature of the solution in the open jacketed pot is raised to 42° C., stirring continuously during the heating process, so that the white granulated sugar is fully dissolved;

[0029] (3) After reaching the target temperature, put in blueberries and stir continuously for 5 minutes; the mass ratio of blueberries to water is 1:3;

[0030] (4) Stop stirring, skim off the blueberry stalks and leaves on the water surface, collect the blueberries suspended in the water and drain.

Embodiment 2

[0032] A method for selecting foreign matter in blueberries, comprising the steps of:

[0033] (1) Add white sugar and water with a mass ratio of 1:5 in an open sandwich pot;

[0034] (2) The temperature of the solution in the open jacketed pot is raised to 40°C, stirring continuously during the heating process to fully dissolve the white granulated sugar;

[0035] (3) After reaching the target temperature, put in blueberries and stir continuously for 3 minutes; the mass ratio of blueberries to water is 1:4;

[0036] (4) Stop stirring, skim off the blueberry stalks and leaves on the water surface, collect the blueberries suspended in the water and drain.

Embodiment 3

[0038] A method for selecting foreign matter in blueberries, comprising the steps of:

[0039] (1) Add white sugar and water with a mass ratio of 1:5 in an open sandwich pot;

[0040] (2) The temperature of the solution in the open jacketed pot is raised to 45° C., stirring continuously during the heating process, so that the white granulated sugar is fully dissolved;

[0041] (3) After reaching the target temperature, put in blueberries and stir continuously for 4 minutes; the mass ratio of blueberries to water is 1:4;

[0042] (4) Stop stirring, skim off the blueberry stalks and leaves on the water surface, collect the blueberries suspended in the water and drain.

Abstract

The invention discloses a method for selecting blueberry foreign matter. The invention uses the white granulated sugar solution with a certain concentration and temperature to realize the screening of blueberries, especially frozen blueberries, and efficiently removes impurities such as leaves, stems, hair, sand and stones. The invention overcomes the shortcomings of the blueberry sorting machine, realizes high-efficiency and low-loss selection of blueberries by using the temperature, density and viscosity of white sugar solution; the use of pectin methylesterase effectively prevents the skin of blueberries from being damaged by high temperature and sugar solution, and improves The integrity of blueberries after screening, while extending the shelf life and improving the freezing resistance of blueberries; CaCl 2 The use of further reduces the skin breakage rate and prolongs the protection period and improves the frost resistance. The invention is simple and quick, has high selection efficiency, can realize non-destructive selection of blueberries, can repeatedly use sugar solution, and has low process cost.

Description

technical field [0001] The invention relates to a method for selecting blueberry foreign matter. Background technique [0002] Wild blueberries grow in the primeval forests north of Daxing'an Mountains in my country. They can withstand the severe cold of minus 50°C. The roots grow in the permafrost all the year round, and the fruits are rich in nutrients. Wild blueberry has high nutritional value and is a rare and rare wild fruit. [0003] Due to the limitation of harvesting conditions, blueberries, especially wild blueberries, contain blueberry stems and blueberry leaves, as well as other foreign objects such as stones and hair, which are usually screened by a blueberry sorting machine or manually. However, the selection effect of the existing blueberry sorting machine is limited, and a certain amount of foreign matter is easy to be mixed and easy to cause damage to the blueberries; the efficiency of manual screening is very low. Therefore, a screening method with high ef...
