Apple-pomace-fermented concentrated fiber product and preparation method thereof

Abstract

The invention discloses an apple-pomace-fermented concentrated fiber product and a preparation method thereof. The preparation method of the apple-pomace-fermented concentrated fiber product comprises the following steps: taking component materials of a fermentation substrate, and uniformly mixing the component materials according to proportion; adding clear water into the well mixed fermentation substrate, carrying out uniform stirring, and carrying out sterilization treatments, so that an intermediate material A is prepared; performing PDA solid ramp activation on candida utilis and geotrichum candidum, respectively preparing the activated candida utilis and geotrichum candidum into suspensions by using sterilized water, and incubating the prepared suspensions in PDA liquid culture media, so that bacteria suspensions used for production are prepared for later use; incubating the bacteria suspensions used for production, namely the candida utilis suspension used for production and the geotrichum candidum suspension used for production in the intermediate material A, so that an intermediate material B is prepared; fermenting the intermediate material B in a multilayer wooden fermentation tray; performing low-temperature drying on the fermentation product by using a fluidized bed dryer; and then, crushing the dried material so as to obtain the apple-pomace-fermented concentrated fiber product. The invention solves the problems of sow constipation or piglet intractable diarrhea and the like caused by lack of dietary fiber in daily feeds.

Description

technical field [0001] The invention relates to a feed material and a preparation method thereof. More specifically, the invention relates to an apple pomace fermented and concentrated fiber product and a preparation method thereof, belonging to the field of resource utilization of agricultural by-product feed. Background technique [0002] Apple pomace is the residue of fresh apples after crushing, squeezing and extracting juice. It is mainly composed of peel, core and residual pulp. It contains rich nutrients such as soluble sugar, vitamins, minerals and cellulose, and is a good feed resource. It has been determined that in the apple pomace peel, the peel pulp accounts for 96.2%, the fruit seed accounts for 3.1%, the fruit stem accounts for 0.7%, and the nitrogen-free extract of apple pomace is 61.5%, of which the total sugar is 15.1%, the crude fat is 6.8%, and the crude protein content 6.2%. In addition to a small amount of husk and fruit stem in the crude fiber, the pu...
