Embodiment 1

[0027] The pre-separation of oily bean skin layer comprises the following steps:

[0028] (1) Pre-treatment of machine harvested fresh oil and beans

[0029] Machine-collected fresh oil beans are selected to remove the spoiled parts such as mildew and corruption, double-action high-pressure water spray cleaning, draining, and negative pressure continuous microwave drying at a temperature of 45°C and a pressure of -0.08MPa to moisture The content is 10%, save it for later use;

[0030] (2) Rapid pre-separation of the skin layer of Yousha bean

[0031] Put the oily bean processed in step (1) into an electromagnetic oscillation environment for cortex pre-separation treatment. The electromagnetic oscillation temperature is 35°C, the electromagnetic oscillation frequency is 2500MHz, and the electromagnetic oscillation treatment time is 10min. After cooling, observe its appearance and find that The tight structure between bean skin and bean meat becomes loose, such as figure 1 As...

Embodiment 2

[0034] The pre-separation of the oily bean skin layer, the steps are as follows:

[0035] (1) Pre-treatment of machine harvested fresh oil and beans

[0036] Machine-collected fresh oil and beans are selected to remove the spoiled parts such as mildew and corruption, double-action high-pressure water spray cleaning, draining water, and negative pressure continuous microwave drying at a temperature of 55°C and a pressure of -0.08MPa to moisture The content is 8%, save it for later use;

[0037] (2) Rapid pre-separation of the skin layer of Yousha bean

[0038] Put the oily beans processed in step (1) into an electromagnetic oscillation environment for cortex pre-separation treatment. The electromagnetic oscillation temperature is 45°C, the electromagnetic oscillation frequency is 2400MHz, the electromagnetic oscillation treatment time is 13min, and cooled to obtain a complete pre-separation of the cortex. Yousha beans, at this time, the looseness between the bean skin and the...

Embodiment 3

[0040] The pre-separation of oily bean skin layer comprises the following steps:

[0041] (1) Pre-treatment of machine harvested fresh oil and beans

[0042] Machine-collected fresh oil and beans are selected to remove the spoiled parts such as mildew and corruption, double-acting high-pressure water spray cleaning, draining water, and negative pressure continuous microwave drying at a temperature of 50°C and a pressure of -0.08MPa to moisture The content is 9%, save it for future use;

[0043] (2) Rapid pre-separation of the skin layer of Yousha bean

[0044] Put the oily beans processed in step (1) into an electromagnetic oscillation environment for pre-separation of the cortex. The electromagnetic oscillation temperature is 40°C, the electromagnetic oscillation frequency is 2450MHz, and the electromagnetic oscillation treatment time is 12 minutes. After cooling, the cortex is completely pre-separated. Yousha beans, at this time, the looseness between the bean skin and the...

Abstract

The invention discloses a method for pre-separating cyperus esculentus peel layer, and belongs to the technical field of food processing. The method comprises the following steps: drying cyperus esculentus, and then performing electromagnetic oscillation treatment to obtain cyperus esculentus with the peel layer pre-separated. When the method is adopted to pre-separate the cyperus esculentus peel layer, the pre-separation success rate reaches 99% or above, the cyperus esculentus is not damaged in the whole process, the appearance of the cyperus esculentus is well reserved, and besides, effective components in the cyperus esculentus can be well protected; and electromagnetic oscillation has enzyme deactivation and sterilization effects, so that the product quality is ensured to a certain extent. The method disclosed by the invention is short in time consumption, simple to operate, capable of greatly reducing the difficulty and workload of subsequent thorough peeling of the cyperus esculentus and improving the peeling efficiency, free of organic solvent residues in the whole process, high in comprehensive utilization value of raw materials, free of generation of waste residues, waste steam and other harmful substances, resource-saving and environment-friendly.

Description

technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to a method for pre-separating skin layers of oily bean. Background technique [0002] Cyperus esculentus (scientific name: Cyperus esculentus L.), also known as tiger nuts, underground walnuts, digital chestnuts, etc., is an annual herb of Cyperaceae, with strong environmental adaptability, and is a high-yield, high-quality comprehensive utilization value. A new type of economic crop that integrates grain, oil, animal husbandry and feeding. At present, oily beans are planted in Jilin, Gansu, Xinjiang, Liaoning, Hebei, Sichuan and other places in my country, with a general yield of 500-1000 kg per mu. The oil yield of the oily bean is as high as 20-36%. Studies have shown that the oily soybean oil is a very high-quality health-care edible oil. At the same time, the oily bean is known as the "king of oil crops" because of its highest yield among the current oil c...
