Embodiment 1

[0012] A kind of processing method of brown sugar ginger tea rich in dietary fiber is characterized in that it is made up of following steps:

[0013] 1) Wash the ginger, slice it, dry it, crush it and sieve it, add deionized water at a solid-liquid ratio of 1:25 (g / mL), keep the temperature at 55°C, adjust the pH to 4 with phosphate buffer, add 3.5% The enzyme activity is 40000U / g acid cellulase for 25 minutes;

[0014] 2) The product obtained in step 1 was ultrasonically treated at 100W for 25 minutes, taken out and centrifuged at 4500r / min for 5 minutes, and the supernatant was collected, precipitated with 4 times the volume fraction of 95% ethanol solution for 2 hours, and filtered to obtain the precipitate. Wash with 4 times the amount of ethanol solution with a volume fraction of 75-78%, dry at 50°C to obtain water-soluble dietary fiber, and pulverize to 80 mesh;

[0015] 3) Add 15% brown sugar, 2% brown sugar, and 5% white sugar to the product obtained in step 2, mix w...

Abstract

The present invention relates to a processing method of dietary fiber enriched brown sugar ginger tea. The processing method is characterized in that soluble dietary fibers extracted from fresh gingerhave a good physiological activity and can increase health-care functions of products, and simultaneously the processing method increases added value of the ginger. Phosphate buffer is used to adjustpH, an activity of acidic dietary fiber enzymes is improved, a rate of enzymatic hydrolysis is improved, an ultrasound treatment is supplemented, and an extraction rate of the dietary fibers is improved.

Description

technical field [0001] The invention relates to the field of ginger tea processing, and mainly relates to a processing method of ginger tea rich in dietary fiber and brown sugar. Background technique [0002] Dietary fiber refers to the sum of high-molecular carbohydrates such as non-starch polysaccharides and lignin that cannot be digested and absorbed by human endogenous enzymes. It has an important role and is an ideal functional health food raw material. It is called the "seventh largest nutrient" after carbohydrates, protein, fat, vitamins, minerals and water. Ginger is not only a common seasoning in people's daily diet, but also a natural raw material for modern medicine and food industry. It is rich in nutrients, including essential oil, gingerol, fatty oil, resin, pentosan, protein, trace minerals, etc. Lots of dietary fiber. Water-soluble dietary fiber extraction methods are commonly used acid method, alkali method, enzymatic method and ultrasonic method. At prese...
