Embodiment 1

[0054] Step 1. Pre-treat the green peppers. Choose fresh green peppers with uniform color, thin skin, no disease spots, and no rot. Wash them with clean water, remove the stalks and internal seeds of the green peppers, drain them and cut them into 4mm strips evenly standby.

[0055] Step 2: Carry out color protection treatment to the green peppers, and perform color protection treatment on the pretreated green peppers. The color protection solution is composed of the following components: 0.20% citric acid, 0.30% ascorbic acid, 0.4% zinc gluconate, and the rest is water. The sum of the contents of the above components is 100%. Soak and protect the color according to the liquid-to-material ratio of 3:1, the solution temperature is 20°C, and the color-protecting treatment time is 20 minutes, then spray the green peppers after the color-protecting treatment with clean water and drain.

Abstract

The invention discloses a process method for combined drying of green peppers. The method specifically comprises the following steps: 1, pretreating the green peppers; 2, performing color protection treatment on the green peppers pretreated in the step 1 by using a color protection solution; 3, performing vacuum osmotic dehydration on the green peppers subjected to the color protection treatment in the step 2 by using penetrating fluid; 4, performing hot air drying on the green peppers after the vacuum osmotic dehydration in the step 3; 5, performing vacuum drying on the green peppers after the hot air drying in the step 4; and 6, performing packaging and storage, namely performing vacuumizing sealing packaging on the green peppers after the vacuum drying in the step 5, and storing the green peppers in a dark and dry place. By adopting the method for combined drying of the green peppers, disclosed by the invention, the green peppers can be subjected to quick, low-energy-consumption, low-cost and high-quality drying processing on the premise that the original color, fragrance, taste and various nutritional ingredients of the green peppers are kept to the maximum extent.

Description

technical field [0001] The invention belongs to the technical field of drying and processing of fruits and vegetables, and relates to a drying process for obtaining green and healthy green peppers by using a combined drying method, in particular to a combined drying method for green peppers Background technique [0002] Green pepper, also known as big pepper, sweet pepper, etc., is characterized by thin skin, thick flesh, large fruit, fresh color, fragrant taste, mild or even no spicy taste, and the content of capsaicin and vitamin C ranks first in the country's spicy products.
