Embodiment 1

[0024] (1) KGM carboxymethylation:

[0025] Add 8g KGM (Wuhan Qiangsen Konjac Food Co., Ltd.) into the three-necked bottle, and while stirring at a constant speed at room temperature, add 25ml of 80% ethanol solution (containing 4.67g of monochloroacetic acid); continue mixing for 2h, then add 15ml of 80% ethanol solution (where Contains the saturated NaOH (80% ethanol solution used to adjust the pH value to 12); take it out after reacting at 55°C for 3 hours; wash repeatedly with 50% ethanol until no chloride ions are detected in the filtrate; then dehydrate with 95% ethanol, vacuum The freeze-dried product carboxymethyl konjac glucomannan CM-KGM is stored in a desiccator. (This part of the technical reference [Wang Chao, Li Bin, Xie Bijun, etc., Konjac Glucomannan Carboxymethylation Method Improvement Research [J], Agricultural Engineering Journal, 2005, 21 (5): 140-144]).

Abstract

The invention discloses composite particles as well as preparation and an application thereof. The composite particles comprise carboxymethylated konjac glucomannan and whey protein with the molar ratio being 4:1 through static electricity acting force, have the particle size ranging from 260 nm to 280 nm, the Zeta potential absolute value of 30 plus / minus 0.5 mv and the contact angle with water ranging from 65 degrees to 70 degrees. The composite particles can be applied to preparation of a Pickering emulsion, and the obtained Pickering emulsion has higher resistance to coalescence and Ostwald ripening of emulsion droplets and has better physical stability.

Description

(1) Technical field [0001] The application relates to a composite particle, its preparation method and its application in the preparation of Pickering emulsion. (2) Background technology [0002] Konjac glucomannan (Konjac glucomannan, KGM) is derived from konjac tubers and is a relatively abundant renewable natural polymer resource. It is widely used for its unique physical and chemical properties such as easy gel formation, high viscosity and water absorption. Food, chemical, pharmaceutical and textile fields. However, some inherent defects of natural KGM, such as slow swelling rate and poor stability, limit its development. Appropriate chemical modification of KGM can improve its performance, improve product quality, and further expand its application fields. [0003] Whey protein isolate (WPI) is a protein isolated and extracted from milk. Whey protein is easy to digest and has high biological value, high digestibility, high protein efficiency ratio and high utilization...
