Abstract
The invention relates to a preparation technology for extracting water-insoluble dietary fiber by use of tea leaves, and relates to the field of extracting water-insoluble dietary fiber by the use of tea leaves. The preparation technology comprises the following steps of: (1) performing superfine grinding on the tea leaves until the tea leaves with the particle size of 250-350 meshes account for 95%; (2) mixing the superfine powder with 1-2% dilute acid according to a proportion of 2-10%, and stirring for 24 hours; (3) filtering, taking supernate and concentrating; (4) soaking in 1-2% dilute acid and dialyzing for 24 hours; (5) taking the dialysis external liquid; and (6) freeze-drying to obtain the water-insoluble dietary fiber. The preparation technology provided by the invention has the beneficial effects that the content of water-insoluble dietary fiber in the prepared tea water-insoluble dietary fiber product is 92.1%, and the product yield is 20.11%.
Description
Relate to the field:
The present invention relates to the preparation field of water insoluble dietary fiber, be specifically related to utilize tea grounds to extract the water insoluble dietary fiber preparation field.
Technical background:
China's tree plant cultivation area and tea yield are the deep processing of the present low and middle-grade tealeaves of the first in the world to extract Tea Polyphenols polysaccharide and water extraction as main, tea grounds is many to be abandoned as rubbish, failing to take full advantage of water insoluble dietary fiber is one of main component of tea grounds, through extracting preparation Aqua Folium Camelliae sinensis insoluble diedairy fiber, can significantly improve economic value added when realizing the tea grounds comprehensive utilization.
Dietary fiber refers to suppress the human small intestine and digests and assimilates, and the edible vegetalitas composition carbohydrate that can partly or entirely ferment at the human body large intestine and the summation of similar material thereof, comprise polysaccharide oligosaccharides lignin and relevant plant material is divided into water-soluble dietary fiber according to deliquescent difference and water insoluble dietary fiber water insoluble dietary fiber (comprising cellulose hemicellulose lignin etc.) has good water imbibition and dilatancy, can promote enterocinesia, Constipation and intestines problem; Can increase satiety, prevent obesity; Can adsorbing enterotoxin and short its, to excrete water insoluble dietary fiber be important functional food ingredient or the main function composition of health products, it is added in other food, can develop a series of food that are rich in the tealeaves dietary fiber, as bread noodles biscuit cake candy beverage and poultry meat products etc.
The extraction of water insoluble dietary fiber mainly contains enzyme chemical method and chemical method, and the larger production cost of the former technique controlling difficulty is higher; Latter's chemical method easy and simple to handle extracts the difference because of technique, and yield and the product quality of water insoluble dietary fiber all had material impact.Therefore take tea grounds as raw material, the specializes in chemistry method is extracted water insoluble dietary fiber, for the comprehensive utilization of in-depth tea grounds lays the foundation.
But there are no prepare the report of water insoluble dietary fiber with tea grounds.
Summary of the invention:
The purpose of this invention is to provide a kind of preparation technology who utilizes tea grounds to extract water insoluble dietary fiber, the preparation water insoluble dietary fiber simultaneously, reduces the waste of resource, the pollution of environment.
Technical scheme of the present invention is step: (1) tealeaf residue is through ultramicro grinding, grinding particle size reaches 95% by the 250-350 order, (2) Ultramicro-powder is mixed according to the ratio of 2-10% with the diluted acid of 1-2%, stir 24h, (3) filter, get supernatant, concentrated, the 24h that dialyses in the diluted acid of (4) immersion 1-2%, (5) get extracellular fluid dialysis, (6) freeze-drying, and get final product.Wherein, diluted acid is hydrochloric acid, acetic acid, sulfuric acid etc.
Conclusion of the present invention is that the result at orthogonal experiment obtains, and the water insoluble dietary fiber content in the Aqua Folium Camelliae sinensis insoluble diedairy fiber product of preparation is 92.1%, and the product yield is that the product yield is 20.11%.
The invention has the beneficial effects as follows:
The water insoluble dietary fiber content of the present invention in the Aqua Folium Camelliae sinensis insoluble diedairy fiber product of preparation is 92.1%, and the product yield is that the product yield is 20.11%.
Specific implementation method:
Embodiment 1: tealeaf residue is through ultramicro grinding, and grinding particle size reaches 95% by 250 orders, and Ultramicro-powder is mixed according to 2% ratio with 1% hydrochloric acid, stirs 24h, filters, gets supernatant, concentrates, and the 24h that dialyses in the hydrochloric acid of immersion 1% gets extracellular fluid dialysis, freeze-drying, and get final product.
Embodiment 2: tealeaf residue is through ultramicro grinding, and grinding particle size reaches 95% by 350 orders, and Ultramicro-powder is mixed according to 10% ratio with 2% nitric acid, stirs 24h, filters, gets supernatant, concentrates, and the 24h that dialyses in the nitric acid of immersion 2% gets extracellular fluid dialysis, freeze-drying, and get final product.
Claims (2)
1. preparation technology who utilizes tea grounds to extract water insoluble dietary fiber, it is characterized in that: step comprises: (1) tealeaf residue is through ultramicro grinding, grinding particle size reaches 95% by the 250-350 order, (2) Ultramicro-powder is mixed according to the ratio of 2-10% with the diluted acid of 1-2%, stir 24h, supernatant, concentrated is filtered, got in (3), (4) immerse the 24h that dialyses in the diluted acid of 1-2%, (5) get extracellular fluid dialysis, (6) freeze-drying, and get final product.
2. utilize tea grounds to extract the preparation technology of water insoluble dietary fiber according to 1 one kinds of claims, it is characterized in that described diluted acid is hydrochloric acid, acetic acid, sulfuric acid.
