Process for bacteria degradation of orange capsule clothes

Abstract

The invention provides a method with high production efficiency, stable product quality, high safety, no environmental pollution, no heavy metal residue and the use of microorganisms to degrade the citrus sac coat. It comprises the following steps: a. Breeding a single fungal strain or combination of strains that meet the following conditions simultaneously: the strain grows fast and can produce a large number of asexual spores or sexual spores; the secreted extracellular pectin degrading enzyme, cellulose The activity of enzyme and hemicellulase is high; the fungal strain that has no quality and safety hazards to canned citrus; b. the bacterial strain selected in step a is made to produce spores or mycelium by fermentation; c. The obtained spores or mycelium are prepared into a microbial degradation agent; d. Peel the cleaned citrus, divide the petals and remove the veins on the orange petals, add them to the microbial degradation agent solution under suitable conditions, and remove them with proper stirring For the bag coat, you have to take off the bag coat and orange petals.

Description

technical field [0001] The invention belongs to a method for removing the capsule coat, in particular to a method for removing the capsule coat of citrus. Background technique [0002] China is a big country in the world's citrus industry. In 2005, the planting area was 1.714 million hectares, ranking first in the world, and the output reached 16.0195 million tons, ranking second in the world. Canned citrus is the leading product of citrus processing in China, accounting for more than 80% of citrus processing. The export volume of canned citrus in 2005 reached 300,000 tons, accounting for more than 60% of the world's trade volume, and the export value reached 198 million US dollars. It is the most competitive product of my country's citrus industry in the international market. "Kingdom of Canned Citrus". [0003] At present, Spain is formulating new technical standards to form technical trade barriers after submitting to the European Union to implement restrictive "special ...

Problems solved by technology

In the processing of canned citrus in my country, the traditional acid-base decapsulation process is basically used. The production efficiency of this process is low, and the product quality is not very stable.

The traditional acid-alkali method for canned citrus decapsulation processing technology has the advantages that the greater the acid-base concentration within a certain range, the higher the removal rate of the capsule, the lower the hardness and brittleness of orange petals, the high petal fragmentation rate and the high water consumption per ton. shortcoming

Moreover, because acid-base treatment requires water rinsing, a large amount of acid-base wastewater is produced. At the same time, the residue of harmful substances such as heavy metals in acid-base reduces the quality and safety of canned citrus products, and it is easy to encounter technical barriers, and the environmental pollution problems it brings are also It is easy to encounter green barriers, which will seriously threaten the dominant position of my country's canned citrus industry in the international market

Moreover, due to the large water consumption of the current process, up to 60-80 tons, it brings a heavy cost burden to the enterprise and restricts the development of the enterprise.
