Low-fat peanut protein beverage and preparation method thereof

Abstract

The invention relates to a low-fat peanut protein beverage and a preparation method thereof. The preparation method comprises the steps of preparing a peanut protein water phase, and preparing the low-fat peanut protein beverage. The low-fat peanut protein beverage disclosed by the invention is prepared from peeled peanuts, and high-quality peanut oil can be obtained at the same time, so that the comprehensive utilization of peanut resources is realized, and the production benefit is greatly enhanced. Due to adding of sodium bicarbonate and homogenization, the stability of the low-fat peanut protein beverage is improved, so that the use of a food level stabilizing agent is avoided, and the production cost of the beverage is lowered; furthermore, a psychological demand of current customers is met. The low-fat peanut protein beverage prepared by the preparation method disclosed by the invention has a unique mellow flavor of peanuts, so that the problems of poor taste and poor flavor of a conventional peanut protein beverage under a high oil extraction rate are solved.

Description

【Technical field】 [0001] The invention belongs to the technical field of food. More specifically, the present invention relates to a low-fat peanut protein beverage, and also relates to a preparation method of the beverage. 【Background technique】 [0002] Since the beginning of the new century, the living standards of Chinese residents have been significantly improved, and their nutritional status has been significantly improved. But in recent years, urban residents have new problems in food nutrition consumption. The first is excessive food nutrition, and the per capita daily consumption of energy, protein and fat is too high. According to the monitoring and statistics of the health department, in 2010, the overweight rate of residents aged 18 and over in my country was 30.6%, and the obesity rate was 12.0%. The overweight rate and obesity rate of urban residents were higher than those in rural areas. The second is the irrational dietary structure. Due to the lack of foo...

The second is the unreasonable dietary structure. Due to the lack of food nutrition knowledge and the temptation of delicacies in the market, unreasonable dietary behaviors such as excessive consumption of meat and fat are common.

[0005] In 1998, people such as Ren Guopu studied the process and process conditions of water-based part-skimmed peanut milk, and compared the flavor of peanut milk under different oil extraction rates (Ren Guopu, Miao Xiubing, "Development of Low-fat Peanut Milk", "Guangzhou Food Industry Science and Technology", 1998, 14 (1), pp35-36); In 2010, Li Yanmin compared the oil extraction efficiency (respectively 27.6%, 46.4% and 67.5%) of 3 different processes, and simultaneously Peanut milk with different oil extraction rates has been studied on flavor (Li Yanmin, Wang Fengling, "Research on Low Fat Peanut Protein Milk", "Grain and Oil Processing", 2010 (9), pp96-97); CN101485478A discloses a combination of peanut kernel, milk ( or full-time milk powder), ethyl bud powder and other raw materials to make peanut double protein drinks, wherein the prepared peanut milk has a common problem: the yield of the by-product peanut oil is low; the prepared products are all added with stabilizers to Achieve product stability

However, the reported low-fat peanut protein beverages all have common problems: the yield of the by-product peanut oil is low; the products prepared by it all need to add stabilizers
