Embodiment 1

[0036] Example 1 Preparation of Dietary Fiber Powder

[0037] (1) Deodorization: After soaking, refining and separating the soybeans, soak the bean dregs in water, adjust the pH3 with citric acid solution; heat the soaked bean dregs to 92°C, and perform a humid heat treatment for 1.5 hours to inactivate the lipoxygenase , reduce the beany smell, and passivate the anti-nutritional factors; then adjust the pH of the mixture to neutral;

[0038] (2) Alkali treatment: use 1mol / L sodium hydroxide solution to adjust step (1) pH of the mixed solution to 12, treatment temperature 68°C, treatment time 45min;

[0039] (3) Enzymatic hydrolysis: Enzymatically hydrolyze the mixed solution after alkali treatment in step (2), the dosage of papain is 0.012g / g wet bean dregs, the enzymolysis temperature is 60°C, and the enzymolysis time is 1h;

[0040] (4) Decolorization: Dilute the enzymolysis solution obtained in step (3) with 5% H in a 50°C water bath 2 o 2 Solution decolorization for 5h...

Embodiment 2

[0044] The preparation method of the homogeneous tomato sauce of embodiment 2 dietary fiber content 3%

[0045] Put the beef broth and diced beef into the sandwich pot and concentrate until the water is about 50% dry, add some tomato sauce and cook together; take 20% water, 3% high active soybean dietary fiber powder and the remaining tomato sauce, seasoning Homogenize the material in a homogenizer at 30Mpa and pour it into a sandwich pot to boil. During the cooking process, stir gently to avoid sticking to the bottom. It can be packaged in glass bottles, sealed or capped after filling, sterilized in a 90°C water bath for 25-30 minutes, and then cooled after sterilization. The glass bottles should be cooled in stages, and the cooled products are finally inspected The qualified ones are the finished products. Store in a cool dry place. The tomato paste prepared by this method generally has a storage period of up to one year and can be conveniently taken as needed. The viscos...

Embodiment 3

[0046] The preparation method of the homogeneous tomato sauce of embodiment 3 dietary fiber content 6%

[0047] Put the beef broth and diced beef into the sandwich pot and concentrate until the water is about 50% dry, add some tomato sauce and cook together; take 20% water, 6% high active soybean dietary fiber powder and the remaining tomato sauce, seasoning Stir the ingredients in a blender for 5 minutes, then pour into the jacketed pot and boil. During the cooking process, stir gently to avoid sticking to the bottom. It can be packaged in glass bottles, sealed or capped after filling, sterilized in a 90°C water bath for 25-30 minutes, and then cooled after sterilization. The glass bottles should be cooled in stages, and the cooled products are finally inspected The qualified ones are the finished products. Store in a cool dry place.

Abstract

The invention discloses a method for preparing homogeneous tomato sauce with high dietary fiber content, which belongs to the technical field of comprehensive utilization of agricultural and sideline products. The method is implemented mainly by the steps of deodorizing bean dregs, and performing alkali liquor treatment, enzymolysis, decoloring, drying, extrusion cooking, drying and super micro milling to prepare super micro milled bean dreg dietary fiber flour for the preparation of the homogeneous tomato sauce with high viscosity and the high dietary fiber content. The method has the advantages that: 1, the high-activity soybean dietary fiber flour can be prepared from the bean dregs by performing the alkali liquor treatment, the enzymolysis, the extrusion cooking and the super micro milling, and has remarkably increased soluble dietary fiber content, remarkably improved water absorptivity and remarkably improved cation exchange capacity; 2, when used for preparing the tomato sauce,the soybean dietary fiber flour treated by the processes is homogenized by a 30 MPa homogenizer so as to make a sauce body more uniform and stable, increase the viscosity and health care value of thetomato sauce and improve the water absorptivity of the tomato sauce; and 3, the utilization of the bean dregs changes the conventional way of utilizing the bean dregs as feeds so as to reduce environmental stress at the same time of realizing reutilization.

Description

technical field [0001] A method for preparing homogeneous tomato paste with high dietary fiber content. The invention belongs to the field of comprehensive utilization of leftovers of agricultural products, relates to ultrafine pulverization technology, and is mainly used for the activation of dietary fiber in bean dregs and its application in homogeneous tomato paste. Background technique [0002] Dietary fiber is an organic polymer compound that cannot be decomposed by human digestive enzymes and is indispensable for maintaining health. It includes hemicellulose, cellulose, lignin, indigestible oligosaccharides, pectin and gum, etc., and is divided into water-soluble and water-soluble Insoluble two types. It has many effects on human physiological health. For example, dietary fiber absorbs water and expands, increasing the volume of feces and reducing the concentration of carcinogenic factors, which is beneficial to promote colon function and prevent colon cancer; it has ...
