Embodiment 1

[0018] A method for producing sodium caseinate by extrusion method, comprising the following steps:

[0019] 1. Raw material characteristics: Qula casein is used as the raw material. The physical and chemical indicators of Qula casein are 92% protein, 1.6% fat and 1.7% ash;

[0020] 2. Puffing transformation: add koji casein into the extruder at a uniform speed, add koji casein powdered sodium carbonate with 8% mass of koji casein at the same time, so that koji casein and powdered sodium carbonate are mixed in the extruder The transformation is carried out in Zhongnei, in which Qula casein and powdered sodium carbonate are converted in sequence through five temperature sections in the extruder, the temperature of section A is controlled at 50°C, the temperature of section B is controlled at 70°C, and the temperature of section C is controlled at 100°C , the D section temperature is controlled at 125°C, the E section temperature is controlled at 120°C, the conversion time is 20...

Embodiment 2

[0023] A method for producing sodium caseinate by extrusion method, comprising the following steps:

[0024] 1. Raw material characteristics: Qula casein is used as raw material. The physical and chemical indicators of Qula casein are 93.5% protein, 1.5% fat and 1.8% ash;

[0025] 2. Puffing conversion: add koji casein into the extruder at a uniform speed, add koji casein powdered sodium carbonate with 12% mass of koji casein at the same time, so that the koji casein and powdered sodium carbonate are mixed in the extruder The transformation is carried out in Zhongnei, in which Qula casein and powdered sodium carbonate are converted in sequence through five temperature sections in the extruder, the temperature of section A is controlled at 60°C, the temperature of section B is controlled at 80°C, and the temperature of section C is controlled at 90°C , the D section temperature is controlled at 115°C, the E section temperature is controlled at 130°C, the conversion time is 25s,...

Embodiment 3

[0029] A method for producing sodium caseinate by extrusion method, comprising the following steps:

[0030] 1. Raw material characteristics: Qula casein is used as the raw material. The physical and chemical indicators of Qula casein are 93.2% protein, 2.0% fat and 1.6% ash;

[0031] 2. Puffing transformation: add koji casein into the extruder at a uniform speed, and at the same time, add koji casein with 1% sodium hydroxide solution, wherein the mass fraction of sodium hydroxide solution is 2% , where the flow rate of the sodium hydroxide solution is 200L / h, so that the Qura casein and the sodium hydroxide solution are converted in the extruder, wherein the Qura casein and the sodium hydroxide solution pass through the extruder successively Five temperature sections are converted, the temperature of section A is controlled at 50°C, the temperature of section B is controlled at 75°C, the temperature of section C is controlled at 100°C, the temperature of section D is controll...

Abstract

The invention relates to a method for producing sodium caseinate by an extrusion process, belonging to the technical field of sodium caseinate. A sodium caseinate sample produced by the extrusion process has a good protein characteristic, all physicochemical indexes of the sodium caseinate sample can accord with the national standard, most importantly, the sodium caseinate sample is high in viscosity and good in color and luster and has a normal flavor, the method has the main advantages of short consumed time and high conversion efficiency in a conversion process, raw materials are almost free of a browning reaction and has a low albuminous degeneration degree because procedures such as re-dissolution of casein, acid precipitation, and colloid grinding in a conventional process are omitted, and the higher product quality standard can be met.

Description

technical field [0001] The invention relates to the technical field of sodium caseinate, in particular to a method for producing sodium caseinate by an extrusion method. Background technique [0002] Sodium caseinate, also known as sodium caseinate or sodium caseinate, is an addition compound of casein and sodium salt. A white or yellowish granule or powder obtained by converting water-insoluble casein into a soluble form. Sodium caseinate has been identified as an unlimited food additive by the Food and Agriculture Organization (FAO) and the World Health Organization (WHO) Food Additives Committee, so it is widely used in meat products, baked goods, beverages, medicine, tobacco, cosmetics, daily Chemical and other industries, in addition, sodium caseinate can also be used in the processing of bread, biscuits, candies, pastries, ice cream, yogurt drinks and margarine. [0003] At present, the domestic production of sodium caseinate basically uses Qula as raw material to pr...
