Problems solved by technology

The filter residue after acid hydrolysis and filtration contains a large amount of insoluble dietary fiber and has not been utilized, so the pectin extracted from the peel is mainly soluble dietary fiber, and does not contain or only a small amount of insoluble dietary fiber, resulting in a huge waste of raw materials

Abstract

The invention relates to pectin containing insoluble dietary fibers, a preparation method and application thereof, belonging to the technical field of food. The preparation method of the pectin containing insoluble dietary fibers comprises the steps of raw material treatment, acidic extraction, coarse filtration, ethanol deposition and drying, and is characterized in that acidic extractive solution is homogenized by a high-pressure spray homogenizer, directly precipitated with alcohol and is filtered and dried. The preparation method has simple technology and easy operation and can greatly extract insoluble dietary fibers and soluble dietary fibers (pectin) in shaddock peel. The prepared pectin containing insoluble dietary fibers contains 50 percent to 70 percent of soluble dietary fiber and 20 percent to 40 percent of insoluble dietary fiber with the pH to be from 2.0 to 5.0. The pectin has soft mouth feel and can be used as a food additive to increase the dietary fiber component in food and regulate the diet structure of customers.

Description

technical field [0001] The invention relates to the field of food technology, in particular to pectin containing insoluble dietary fiber. Background technique [0002] Dietary Fiber (Dietary Fiber) was first proposed by H.C.Trowell in 1972 and defined in 1976 as "the general term for polysaccharide carbohydrates and lignin that are not digested and absorbed by the human body. It is called the "seventh largest nutrient". Dietary fiber It is not digested and absorbed in the small intestine of the human body. But it can be fermented by bacteria in the large intestine of the human body. In recent years, domestic and foreign researchers have found that dietary fiber can prevent coronary heart disease, arteriosclerosis, hyperlipidemia, diabetes, obesity and other "civilization" Dietary fiber can also reduce the incidence of dental caries, delay the residence time of food in the stomach, shorten the time for food to pass through the intestinal tract, prevent colorectal cancer and i...
