preparation example Construction

[0049] The method for preparing Physalis edulis polysaccharide provided by the invention improves the yield of Physalis edulis polysaccharide prepared from Physalis edulis, shortens the production cycle, reduces the production cost, and obtains Physalis edulis polysaccharide with high purity. The yield of the existing Physalis polysaccharide extraction methods, such as the sevage method, is mostly between 3% and 6%, which is significantly lower than that of the extraction method provided by the present invention.

[0050] The present invention also provides a food prepared based on the aforementioned Physalis polysaccharide, that is, Physalis food.

[0051] The raw materials for making physalis food mainly include xylitol and the aforementioned polysaccharides of physalis. Optionally, the physalis food also includes low-gluten flour and butter.

[0052] The method for making the physalis food comprises: melting butter at room temperature, adding physalis polysaccharides and x...

Embodiment 1

[0056] A kind of physalis polysaccharide, its preparation method is as follows:

[0057] After the fresh physalis is washed, it is pulverized to obtain fruit pulp. Mix the fruit pulp with pectinase and cellulase, stand at 50°C for enzymolysis, then filter and remove residue to obtain the enzymolysis material. The enzymolysis material and maltodextrin are mixed evenly with water to obtain an aqueous solution with an enzymolysis material content of 25 wt % and a maltodextrin content of 8 wt %. The conditions for spray drying to obtain powder materials by spray drying are: aqueous solution feed flow rate 5mL / min, air inlet temperature 1600°C, exhaust air volume 20m 3 / h. Dissolve the powder and abrasive in distilled water, and then perform ultrasonic extraction with a countercurrent ultrasonic device under the conditions of 80° C. and a frequency of 20,000 Hz by a supersonic extraction method to obtain an extract. The extract is dispersed in ethanol, and after precipitation oc...

Embodiment 2

[0059] A kind of physalis polysaccharide, its preparation method is as follows:

[0060] After the fresh physalis is washed, it is pulverized to obtain fruit pulp. Mix the fruit pulp with pectinase and cellulase, stand at 65°C for enzymolysis, then filter and remove residue to obtain the enzymolysis material. The enzymolyzed material and maltodextrin are mixed evenly with water to obtain an aqueous solution with an enzymatically hydrolyzed material content of 50 wt % and a maltodextrin content of 8-15 wt %. The conditions for spray drying to obtain powder materials by spray drying are: the feed flow rate of aqueous solution is 10mL / min, the air inlet temperature is 1200°C, and the exhaust air volume is 50m 3 / h. Dissolve the abrasive material in distilled water, and then perform ultrasonic extraction with a countercurrent ultrasonic device under the conditions of 90° C. and a frequency of 40,000 Hz by a supersonic extraction method to obtain an extract. The extract is dispe...

Abstract

The invention relates to physalis pubescens food, physalis pubescens polysaccharide and a preparation method of the physalis pubescens polysaccharide and belongs to the field of food. The preparation method of the physalis pubescens polysaccharide comprises the steps of carrying out enzymolysis on physalis pubescens so as to release a target containing physalis pubescens polysaccharide components in physalis pubescens, extracting the target by virtue of an ultrasonic extraction method so as to obtain an extract, and carrying out separation and purification on the extract by virtue of macroporous adsorption resin. By utilizing the preparation method of the physalis pubescens polysaccharide, the physalis pubescens polysaccharide with few impurities and high purity degree and yield can be obtained.

Description

technical field [0001] The invention relates to the field of food, in particular to a Physalis edulis food, Physalis edulis polysaccharide and a preparation method thereof. Background technique [0002] Physalis tomentosa, also known as Huanggu Niang, has a sweet and sour taste, bright orange-yellow color, and is a natural green food. It contains 18 amino acids and minerals needed by the human body, as well as unsaturated fatty acids such as linoleic acid and linolenic acid, and a large amount of cellulose. The polysaccharide contained in it has the health effects of lowering blood pressure, lowering blood sugar and enhancing immunity. But at present, Physalis edulis is mainly sold in the form of fresh fruit, and there are technical problems such as transportation, storage and preservation, which restrict the development of Physalis edulis industry. [0003] At present, most of the deep processing and utilization of Physalis edulis is in the beverage industry, and the prod...
