Problems solved by technology

The results show that: when the lemon peel residue is treated under the conditions of 1% enzyme dosage, enzymolysis time of 12min, enzymolysis temperature of 60°C, and pH value of 6, the SDF / IDF of the lemon dietary fiber product obtained is 0.67, and the product quality is better (China Brewing, 2016,35(4):181-184), but the amount of enzyme is larger

Embodiment 1

[0027] The preparation method of the high-quality lemon dietary fiber compound enzyme of the present embodiment comprises the following steps:

[0028] First, prepare lemon peel powder. The specific method is: put the lemon peel residue into water twice the weight of the tare for heating, and boil for 5 minutes to destroy the pectinase in the lemon peel residue; then rinse the boiled lemon peel with clean water. Dregs until colorless, preliminarily removing various non-colloidal substances such as aromatic substances, sugars, bitter substances and pigments; drying and pulverizing the treated lemon peel residues to finally obtain lemon peel powder.

[0029]The prepared lemon peel powder also needs to do the following treatment: the lemon peel powder is mixed with the mixed buffer solution of citric acid and sodium citrate with a weight ratio of 1:15 and pH of 5, and then adds 0.05% by lemon peel powder weight. % cellulase and 0.05% α-amylase were slowly stirred, and kept at 50°...

Embodiment 2

[0035] The preparation method of the high-quality lemon dietary fiber compound enzyme of the present embodiment comprises the following steps:

[0036] First, prepare lemon peel powder. The specific method is as follows: put lemon peel residue into water twice the weight of the skin, heat it, and boil it for 5 minutes to destroy the pectinase in the lemon peel residue; then rinse the boiled lemon peel with clean water. Dregs until colorless, preliminarily removing various non-colloidal substances such as aromatic substances, sugars, bitter substances and pigments; drying and pulverizing the treated lemon peel residues to finally obtain lemon peel powder.

[0037] The prepared lemon peel powder also needs to be processed as follows: the lemon peel powder is mixed with the mixed buffer solution of sodium dihydrogen phosphate and disodium hydrogen phosphate at a weight ratio of 1:20 and pH of 6, and then added with lemon peel powder 0.04% by weight of papain and 0.12% of α-amylas...

Embodiment 3

[0043] The preparation method of the high-quality lemon dietary fiber compound enzyme of the present embodiment comprises the following steps:

[0044] First, prepare lemon peel powder. The specific method is: put the lemon peel residue into water that is 3 times the skin weight, heat it, and boil it for 5 minutes to destroy the pectinase in the lemon peel residue; then rinse the boiled lemon with clean water Dregs until colorless, preliminarily removing various non-colloidal substances such as aromatic substances, sugars, bitter substances and pigments; drying and pulverizing the treated lemon peel residues to finally obtain lemon peel powder.

[0045] The obtained lemon peel powder also needs to be processed as follows: the lemon peel powder is mixed with the mixed buffer solution of citric acid and disodium hydrogen phosphate at a weight ratio of 1:30 and pH of 4, and then added by lemon peel powder weight. 0.1% amyloglucosidase and 0.4% bromelain were stirred slowly, and k...

Abstract

The invention discloses a preparation method of a high-quality lemon meal fiber compound enzyme. The method is characterized by comprising the following steps of (1), adding lemon peel slag into waterwith weight which is 2-3 times of that of the peel, performing heating and boiling by 5-10 min, rinsing by clear water to colorless, and drying and crushing for forming lemon peel powder; and (2), mixing the lemon peel powder with buffer solution which has a weight ratio of 1:15-40 and a pH value of 4-8, then adding an enzyme preparation with the weight ratio of 0.04-1.0% to the lemon peel powderand performing slowly stirring, performing insulation extraction for 0.5-3 hours at the temperature of 40-70 DEG C, heating the extracting solution to above 95 DEG C, performing insulation by 5-10 min for obtaining meal fiber extract solution, etc. According to the method of the invention, when the compound enzyme is utilized for preparing the meal fiber, the buffer solution with the pH value of4-8 is added for cooperation, therefore not only is extraction time of the meal fiber greatly reduced, but also balance of the meal fiber is improved. Furthermore use amount of the enzyme preparationand an extraction cost are reduced.

Description

technical field [0001] The invention relates to the field of dietary fiber processing, in particular to a method for preparing a high-quality lemon dietary fiber compound enzyme. Background technique [0002] Dietary fiber (DF) has the functions of reducing gastrointestinal transit time, increasing feces volume, lowering total blood cholesterol, lowering postprandial blood sugar, etc., and can reduce and prevent diseases such as coronary heart disease, diabetes, hypertension, obesity, myocardial infarction, and colitis , known as the "seventh largest nutrient" necessary for the human body. Therefore, dietary fiber has attracted the attention of researchers from various countries and has become a research hotspot in the field of food. [0003] According to water solubility, DF can be divided into two types: soluble dietary fiber (SDF) and insoluble dietary fiber (IDF): SDF can prevent gallstones, remove harmful metal ions (such as mercury, arsenic, cadmium and copper), preve...
