AI Technical Summary

Problems solved by technology

The technical defect that these prior art exists is as follows: A, the water infusion of water-bath leaching technology and the squeezed juice that extracts yacon fruit fructo-oligosaccharide by squeezing the juice are relatively easy to brown, are difficult to handle, and the processing process is loaded down with trivial details; B, hot water bath The leaching method temperature is high, side reactions are many and fructo-oligosaccharides are easily oxidized, and the fructo-oligosaccharides in yacon are easily oxidized, and the extraction rate is low, which is not as good as ultrasonic extraction; C, color-protecting agent is very important in its extraction process. The problem affects the result too much

Embodiment 1

[0100] Embodiment 1: the extraction of yacon fruit fructooligosaccharide

[0101] The implementation steps of this embodiment are as follows:

[0102] A. Pretreatment

[0103] Wash the fresh yacon with clear water, then cut the yacon slices into slices with a thickness of 0.6cm, and then dry the yacon slices at a temperature of 60°C until the water content is less than 5% by weight to obtain a Yacon dry matter;

[0104] B. Extraction

[0105] Use the pulverizer sold by Yongkang Jiupin Industry and Trade Co., Ltd. under the trade name high-speed multifunctional pulverizer to pulverize the yacon dry matter obtained in step A into yacon powder with a particle size of 80, and then mix the yacon powder with citric acid The volume ratio of the aqueous solution is 1:36, adding concentration in the said yacon powder is the citric acid aqueous solution extractant of 0.3% by weight, then use the KQ-100E ultrasonic cleaner sold by Kunshan Ultrasound Instrument Co., Ltd. Ultrasonic eq...

Abstract

The invention relates to yacon fructooligosaccharide and a preparation method thereof, and the method comprises steps of pretreatment, extraction, flocculation, extraction and concentration. The fructooligosaccharide content of the yacon fructooligosaccharide accounts for 90% or more by weight of the total yacon fructooligosaccharide. The yacon fructooligosaccharide extraction method is lower in solvent total consumption compared with the prior art, the yacon fructooligosaccharide extraction rate is high, and the content of yacon fructooligosaccharide obtained by using the method is high. Therefore, the method is extremely beneficial for industrialized large-scale production because of relatively small solvent consumption, high efficiency, high content and simple and practicable operation.

Description

【Technical field】 [0001] The invention belongs to the technical field of extracting oligosaccharides from plants. More specifically, the present invention relates to a yacon fruit fructooligosaccharide, and also relates to a preparation method of the yacon fruit fructooligosaccharide. 【Background technique】 [0002] Yacon (Smallanthus sonchifolius [Poepp. & Endl.] H. Robinson), also known as Yacon, is a member of the Compositae (Comppositae or Asteraceae) plant family. Traditional tuber food of the indigenous Indians of the alpine regions. Yacon pulp tastes like a pear, juicy and crystal clear, sweet and crisp, contains more than 20 kinds of essential amino acids, rich minerals and a large amount of soluble fiber, including fructooligosaccharides, which is a low-calorie food, but its carbohydrates are It is not absorbed by the human body, so it is very suitable for diabetics and dieters. In South America, it is often used as a health food for diabetics, various digestive ...
