AI Technical Summary

Problems solved by technology

However, due to technical problems, the loss of water-soluble fiber, hemicellulose or cellulose in the product is relatively large. Such dietary fiber has low physiological activity and can only be used as a general non-energy filler and cannot increase the value of dietary fiber.

Abstract

The invention provides a craft for preparing dietary fiber using kumquat marc, which adopts kumquat or kumquat marc as materials. After washing, drying, grinding, decolorizing treatment and acid treatment to the materials, a water-insoluble crude product of dietary fiber is filtered out through alkali treatment to the filter residue; a water soluble crude product of dietary fiber is filtered out through alcohol precipitation to the filtrate after acid treatment; and a dietary fiber is obtained after a mixed crude product being dried and superfine comminuted; the craft adopts kumquat or the kumquat marc which is made from the machining process to the kumquat beverage as materials, after decoloration and acid alkali treatment, alcohol condensation, and superfine comminution, a kumquat dietary fiber with high activity is developed. The craft has the advantages of waste reuse, obvious economic benefit, optimized process condition for preparation, improvement of active component of the kumquat dietary fiber and increase of the value of the dietary fiber.

Description

technical field [0001] The invention belongs to the field of food processing, and more specifically relates to a process for preparing dietary fiber from kumquat pomace. Background technique [0002] Dietary fiber refers to non-starch polysaccharides that are not digested by human digestive enzymes. They are generally divided into two categories: water-soluble and water-insoluble: water-insoluble dietary fiber refers to foods that are not digested by human digestive enzymes and are insoluble in hot water. Fiber, such as cellulose, hemicellulose, lignin, protopectin, etc. derived from plants; water-soluble dietary fiber refers to dietary fiber that is not digested by human digestive enzymes and is soluble in warm and hot water, such as source Plant pectin, gum arabic, seed gum, taro mannan, etc. Modern studies have shown that dietary fiber is a type of active polysaccharide that has certain physiological functions for the human body. Because of its strong water absorption ca...
