Problems solved by technology

[0005] At present, although the extraction method of agaric pectin (vegetable gum) has been reported, it is extracted after drying. Because the moisture content of agaric is extremely high (up to 90%), the extraction after drying not only consumes a lot of energy, but also At the same time, the chlorophyll is destroyed during the drying process, and it is impossible to obtain vegetable gum and chlorophyll at the same time. In addition, the yield of vegetable gum after drying is also greatly reduced.

[0033] 2. Beating fungus

[0034] Mix 1000 grams of fungus with 100 ml of beating agent (mixing ratio: 1:0.1), beat with an electric beater, pass through a 20-mesh sieve, remove fibrous matter that is difficult to sieve, and obtain agaric vegetable pulp. The beating agent is prepared from water, sodium hexametaphosphate, ethanol and citric acid in a weight-to-volume ratio of 0.001:0.0001:0.1:0.001, 1ml of water, 0.1g of sodium hexametaphosphate, 98ml of ethanol and 1 g of citric acid;

[0035] 3. Chlorophyll extraction

[0036] The fungus pulp was centrifuged at 10000 rpm for 10 minutes to obtain 700 ml of centrifuged supernatant and 200 g of centrifuged sediment. Add 20 millilit...

Embodiment 2

[0048] The specific operation steps for simultaneously preparing agaric vegetable gum and agaric vegetable chlorophyll copper sodium salt from agaric are as follows:

[0049] 1 、 Pretreatment of fungus

[0050]Put the freshly harvested fungus in a well-ventilated place without rain for 12 hours;

[0051] 2. Beating fungus

[0052] Mix 1000 grams of fungus with 500 ml of beating agent (mixing ratio: 1:0.5), beat with an electric beater, and pass through a 100-mesh sieve to remove fibrous substances that are difficult to sieve to obtain agaric vegetable pulp. The beating agent is prepared by water, sodium hexametaphosphate, ethanol and citric acid in a weight volume ratio of 0.1:0.001:1:0.002, water 45ml, sodium hexametaphosphate 0.5g, ethanol 455ml and citric acid 1g;

[0053] 3. Chlorophyll extraction

[0054] The fungus vegetable pulp was vacuum filtered to obtain 1000 ml of filtrate and 180 g of filtered residue. Add 90 milliliters of chlorophyll extractant to 180 grams...

Abstract

The invention discloses a technological method for simultaneously preparing basella rubra vegetable gelatin and basella rubra sodium copper chlorophyllin from basella rubra. The method includes the following specific technological steps: (1) mixing and pulping fresh basella rubra and a pulping agent; (2) centrifuging or filtering the basella rubra pulp, mixing filtered residues or centrifugation sediment with a chlorophyll extractant, centrifuging or filtering, combining the filtrate obtained for two steps or centrifuging the supernatant to obtain the basella rubra chlorophyll extracting solution, and simultaneously obtaining the sediment or filtered residues; (3) washing and drying the sediment or filtered residues to obtain the basella rubra vegetable gelatin; (4) performing saponification, extraction, cupric ion substitution and impurity removal to the basella rubra chlorophyll extracting solution to obtain the basella rubra sodium copper chlorophyllin. According to the method provided by the invention, the yield of the basella rubra vegetable gelatin is improved by 30% above, furthermore, the energy consumption is reduced by 90% above, and besides, the by-product of the basella rubra sodium copper chlorophyllin can be obtained, and the comprehensive utilization level of basella rubra can be greatly improved.

Description

technical field [0001] The invention belongs to the technical field of extraction and preparation of biological products, and in particular relates to a process for extracting vegetable gum and sodium copper chlorophyllin from fungus. Background technique [0002] Vegetable gum is a polysaccharide substance, which is widely present in the fruit, root, leaf and other tissues of higher plants, and plays a role in softening and sticking the tissues. Utilizing the property that plant gum can form very good jelly under calcium ion or high concentration sugar and low pH, it can be widely used as gelling agent, thickener, emulsifier, stabilizer and dehydrating agent in food, chemical industry , pharmaceutical and other industries. At present, my country's food industry is booming after the reform and opening up, and the demand for plant glue is large. The annual demand is about 2,000 tons, most of which must be imported from abroad. The supply of domestic products exceeds demand, ...
