Embodiment 1

[0076] Embodiment 1: Preparation of low-fat peanut milk drink

[0077] The steps of the preparation method are as follows:

[0078] A. Preparation of peanut protein aqueous phase

[0079] Use a pulverizer sold by Changzhou Wujin Xingye Machinery Equipment Co., Ltd. under the trade name three-roll mill to pulverize the peeled peanut kernels to a volume average particle size of 20 μm to obtain a peanut pulp; then

[0080] According to the weight ratio of peanut pulp and deionized water of 1:6, the peanut powder and deionized water were stirred and mixed evenly, and then the pH of the system was adjusted to 9.2 with 1N sodium hydroxide aqueous solution. In the fermenter sold by Technical Engineering Equipment Co., Ltd. under the trade name Mechanical Stirring Stainless Steel Fermenter, carry out alkaline extraction at an alkaline extraction temperature of 40°C for 5 hours, and then use a decanter centrifuge sold by Jiangsu Giant Machinery Co., Ltd. at 3500rpm Next, the alkali e...

Abstract

The invention relates to a low-fat peanut milk beverage as well as a preparation method thereof. The preparation method comprises the following steps: preparing a peanut protein water phase, preparing a low-fat peanut milk beverage and the like. According to the invention, a water phase obtained after oil is extracted from peanuts by an enzyme aided water extraction process to be used for preparing the low-fat peanut milk beverage, and thus a great amount of high-quality peanut oil is obtained and nutritious healthy low-fat peanut milk is obtained further; the peanut resource is utilized fully; the problem that water-phase protein is hydrolyzed by enzyme to generate bitter flavor does not exist. The low-fat peanut milk beverage provided by the invention has mellow peanut flavor, is good in stability, is low in fat content, meets the psychological need of consumers, and has a wide market prospect.

Description

【Technical field】 [0001] The invention belongs to the technical field of food. More specifically, the present invention relates to a low-fat peanut milk beverage, and also relates to a preparation method of the low-fat peanut milk beverage. 【Background technique】 [0002] Peanuts are mainly grown in the tropics and subtropics and along the Mediterranean coast. The protein content in peanuts is 20-30%, and the fat content is about 40-50%, which is a high-quality resource of oil and vegetable protein. In addition, peanuts are also rich in vitamin B 2 , PP, A, D, E, calcium and iron and other nutrients beneficial to the human body. The biological value (BV) of peanut protein is 55.5, the protein efficacy ratio (PER) is 1.7 (casein is 2.5), and the true digestibility (TD) is 87%. Its nutritional value is second only to soybean protein in vegetable proteins. The use of peanuts to produce beverages has high nutritional value. [0003] Enzyme-assisted water substitution method...
