Problems solved by technology

And microwave drying is used in the later stage of drying. At this time, the moisture content in honeysuckle is low and the moisture distribution is uneven, which is prone to the phenomenon that the material absorbs microwave energy unevenly, resulting in uneven heating or local overheating, which will have a negative impact on product quality.
In addition, this method uses multiple processes such as solution immersion, heat pump drying, and microwave drying. The operation is complicated and the drying cost is high, so it is not suitable for industrial application and actual production.
Aiming at the problem that honeysuckle is easy to enzymatically oxidize and brown, but is not suitable for color protection by soaking, it is necessary to propose a new method for quickly drying honeysuckle to reduce production costs

Abstract

The invention discloses a method for rapidly guaranteeing the quality of dried honeysuckle flower, and belongs to the technical field of agricultural product drying processing. The method is characterized in that organic matter steam and preferably ethanol steam is introduced in the initial stage of the gas conditioning of the dried honeysuckle flower for 10-20min, and the volume fraction of the ethanol steam in a gas conditioning drying medium is 1-5%. The method combines the organic matter steam gas conditioning drying with nitrogen gas conditioning drying, nitrogen introduction and organic matter steam spraying respectively reduce the oxygen content in drying environment, effectively reduce the number of oxygen molecules involved in an enzymatic oxidation reaction, and inhibit the enzymatic reaction; and the organic matter steam further reduces the rate of the enzymatic oxidation reaction by inhibiting the activity of polyphenol oxidase in honeysuckle flower to realize the protection of an active ingredient chlorogenic acid and the maintenance of the product color and maximally guarantee the quality of dried honeysuckle flower products.

Description

technical field [0001] The invention relates to a method for quickly drying honeysuckle with high quality and belongs to the technical field of drying and processing of agricultural products. Background technique [0002] Drying is the process of removing moisture inside the material by applying heat to the wet material. It has the characteristics of extending product shelf life, reducing packaging costs, reducing freight costs, improving appearance quality, and retaining original flavor and nutritional value. Drying is an important means of food and agricultural product preservation and the key to processing high-quality dried products. The traditional hot air drying processing technology has high energy consumption and low product quality, making it difficult to meet people's needs for high-quality dried products. New drying technologies such as vacuum drying, vacuum freeze drying, etc., have mild drying temperature, can effectively reduce the oxygen content in the drying...
