Embodiment 1

[0028] A method for extracting banana peel pectin, the method comprising the steps of:

[0029] (1) Pretreatment: wash and remove impurities from the banana peel, cut it into small pieces, put it in a mixed solution containing 0.4% sodium bisulfite, 0.3% citric acid, and 0.4% sodium chloride and soak for 10 minutes to protect the color. Water steam inactivates enzymes on the banana peels after color protection for 10 minutes, rinses them with warm water for 3 times after the banana peels are cooled, squeezes the moisture on the surface of the banana peels with gauze, and then puts the banana peels in an oven at 60°C to dry to moisture 5%, crushed into 200 mesh banana peel powder for subsequent use;

[0030] Surfactant solubilization: add 35L of 1.0% ammonium oxalate aqueous solution to every kilogram of banana peel powder, obtain the extraction feed liquid after stirring evenly, add fatty alcohol polyoxyethylene ether sodium sulfate (AES) by 1% of feed liquid weight, the obtai...

Embodiment 2

[0036] A method for extracting banana peel pectin, the method comprising the steps of:

[0037] (1) Pretreatment: Wash and remove impurities from the banana peel, cut it into small pieces, put it into a mixed solution containing 0.4% sodium bisulfite, 0.3% citric acid, and 0.4% sodium chloride and soak for 15 minutes to protect the color. Water steam inactivates enzymes on the banana peel after color protection for 5 minutes, rinses it twice with warm water after the banana peel is cooled, squeezes the moisture on the surface of the banana peel with gauze, and then puts the banana peel in an oven at 60°C to dry to moisture 4%, crushed into 100 mesh banana peel powder for subsequent use;

[0038] (2) Surfactant solubilization: add 0.8% ammonium oxalate aqueous solution 30L for every kilogram of banana peel powder, obtain extracting feed liquid after stirring evenly, add Tween 80 (span-80) by 0.5% feed liquid weight, the obtained The feed solution was stirred in an ultrasonic w...

Abstract

The invention provides a method for extracting banana peel pectin and belongs to the technical field of natural product extraction. Waste banana peel generated after deep processing of bananas is adopted as a raw material, and the finished natural, safe and non-toxic plant source pectin is prepared through the steps of pretreatment, surfactant solubilizing, microwave-assisted extraction, decoloring and deodorizing, concentration and alcohol precipitation. The surfactant and ultrasonic wave and microwave technologies are combined, extraction consumed time is effectively shortened, the extraction yield is increased, the purposes of saving energy and achieving environment friendliness are achieved, and an effective and feasible reference is provided for comprehensive utilization of the bananas.

Description

【Technical field】 [0001] The invention relates to the technical field of natural product extraction, in particular to a method for extracting banana peel pectin. 【Background technique】 [0002] Pectin is a natural polymer compound, widely used in food, medicine, daily chemical industry and other industries. The application of pectin in food is mainly used as a thickener in the production of jam, jelly, and beverages, and as a stabilizer in the production of ice cream. In addition, pectin can also be used as an emulsifier for cosmetics, an auxiliary agent for pharmaceutical production, etc. [0003] Bananas abound in my country's Hainan, Guangdong, Fujian, Guangxi and other places. In recent years, my country's banana planting industry has developed rapidly. In 2004, the total output of bananas was about 6 million tons, accounting for 47% of the total fruit output of the four provinces in South China. In recent years, the deep processing of bananas has developed rapidly in...
