Dehulling method of fresh pepper fruit

Abstract

The invention discloses a dehulling method of fresh pepper fruit, which comprises the follow steps: (1) selecting fresh pepper fruit; (2) soaking: soaking the fresh pepper fruit spikes in pectinase liquid with the volume concentration of 1-5 per thousand till the peel is corrupted, wherein the weight ratio of the fresh pepper fruit spikes to the pectinase liquid is 1-2:2-3; and (3) dehulling and washing: fishing out the soaked pepper fruit, and removing the peels and pedicles, thus obtaining pepper corns. The whole process is simple, the treatment is easy, the period is short (about 3-4 days), and the high-quality white peppers can be processed in a short period, the difficulties of long process period, low efficiency and poor quality of the white pepper are solved, the production quality of the white pepper is improved, the water resource is saved, sewage discharge amount is decreased, the production cost is reduced, standardizing and large-scale production is realized, technical support is provided for China to build a safe, high-efficiency, energy-saving and environment protective processing technique system, the upgrade of pepper industry is promoted, and the market competitiveness of Chinese pepper products is further strengthened.

Description

technical field [0001] The invention relates to a method for peeling plant fruits, in particular to a method for peeling fresh pepper fruits. Background technique [0002] Pepper (Piper nigrum L.) is a perennial evergreen climbing vine belonging to the family Piperaceae. It is native to India and is an important spice crop in the world. It is widely used and has high economic value. The seeds of pepper contain ingredients such as volatile oil, piperine, crude fat, and crude protein, and are popular condiments; in the pharmaceutical industry, they can be used as stomachic agents, antipyretics, and bronchial mucosal stimulators to treat indigestion, cold, etc. Phlegm, cough, enteritis, bronchitis, cold and rheumatism, etc.; used as a preservative and natural food additive in the food industry. [0003] my country's pepper products are dominated by white pepper, whose production accounts for more than 90% of the total pepper output. Peeling is the most important part of the w...

Problems solved by technology

Peeling is the most important part of the white pepper processing process. At present, the traditional wet processing is the main method of processing white pepper. That is, fresh ripe pepper fruits are packed in bags and then soaked in "still water" or "running water" in a pool until the peels are fully rotten. It usually takes 7 to 15 days to complete, and the water needs to be changed. There are defects such as long processing cycle, large water consumption, high labor intensity, easy to produce odor, and dark product color, resulting in heavy odor, appearance and color of white pepper products. Poor quality, water consumption and a large amount of sewage in the processing process, low labor efficiency, lack of market competitiveness, and difficulty in meeting relevant international standards have resulted in not only a decrease in the export volume of pepper in my country year by year, but also a lower export price than similar products in the world's major producing countries. It seriously restricts the international trade of pepper products in our country, cannot meet the current development requirements of large-scale and industrialized pepper processing, and hinders the sustainable development of domestic pepper planting and processing industries
