Embodiment Construction

[0018] A detailed description will be given below in conjunction with the accompanying drawings and embodiments.

[0019] The feed liquid used is soybean extract, and the water content is 94%-95%.

[0020] Pretreatment: Batch 1: Filtered with 50-mesh nylon filter bag, Batch 2: Filtered with 100-mesh nylon filter bag, Batch 3: Filtered with 200-mesh nylon filter bag;

[0021] Ultrafiltration sugar removal: the ultrafiltration membrane used in batch 1 and batch 2 has a molecular weight cut-off of 5,000 Daltons, and the ultrafiltration membrane used in batch 3 has a molecular weight cut-off of 10,000 Daltons;

[0022] Nanofiltration concentration: The nanofiltration membrane used is a composite nanofiltration membrane with a molecular weight cut-off of 150-300 and a working pressure of 1.5-2.5Mpa.

[0023] Such as figure 1 Implementation steps: 1. The soybean extract is first pretreated by a filter bag; 2. After the pretreated soybean extract liquid enters the ultrafiltration m...

Abstract

The invention discloses a production method of low-sugar soya-bean milk, which mainly comprises the following steps: (1) pretreatment: soybean extracting solution is filtered by a filtering bag, suspended matters such as bean dregs in the soybean extracting solution can be removed, so as to ensure the safety of a membrane system and obtain clear solution of the soybean extracting solution; (2) sugar removal by hyperfiltration: the clear solution of the soybean extracting solution, which is pretreated, enters into a hyperfiltration membrane system, hyperfiltration concentration is carried out,and the solution is concentrated by two times, water is added in the concentrated solution for washing, so as to wash sugar ingredient in the concentrated solution in a circulating way and measure thesugar degree in the concentrated solution and dialysate at regular time, until the sugar ingredient in the concentrated solution is reduced to be stable, the treatment of sugar removal by hyperfiltration is stopped; (3) nanofiltration and contraction: the hyperfiltration dialysate is placed in a nanofiltration membrane system, the sugar ingredient in the dialysate is concentrated and extracted, and the nanofiltration dialysate water returns back to the production to be used as pulping water. In the whole treating process, other substances are not added, the treatment is carried out at normaltemperature, and the method has the advantages of energy saving, environmental protection and good separating effect.

Description

technical field [0001] The invention relates to a production method of low-sugar soybean milk, in particular to a production method of low-sugar soybean milk using membrane separation technology. Background technique [0002] Soybean milk is a kind of drink that people love, and it is also a kind of nutritious food suitable for all ages. It enjoys the reputation of "plant milk" in Europe and the United States. Soy milk is rich in nutrients such as vegetable protein, but it also contains a certain amount of sucrose and monosaccharides. With the improvement of living standards, low-sugar foods are gradually gaining the favor of customers. Traditional separation methods such as centrifugation, plate-and-frame filtration, etc. are difficult to remove sugars in soybean milk, which brings considerable difficulties to the production of low-sugar soybean milk, so the technology of the present invention fills this gap. Contents of the invention [0003] The purpose of the present...
