Sausage containing bamboo shoot fiber-polyphenol compound and preparation method of sausage containing bamboo shoot fiber-polyphenol compound

Abstract

The invention relates to a sausage containing a bamboo shoot fiber-polyphenol compound and a preparation method of the sausage containing the bamboo shoot fiber-polyphenol compound. Bamboo shoot powder subjected to acidolysis pretreatment is further subjected to superfine grinding in an air-stream mill to obtain micron bamboo shoot fibers, and owing to excellent adsorption characteristics, the micron bamboo shoot fibers and a polyphenol extract form the stable bamboo shoot fiber-polyphenol compound in solution; ice water is substituted by low-temperature bamboo shoot fiber-polyphenol compound solution for being added into sausage stuffing, and the high-quality sausage is obtained after filling, cooking, cooling and packaging. By polyphenol adsorption and protection effects of the micron bamboo shoot fibers, problems of proneness to oxidation, poor stability and low biological absorption and utilization rate of polyphenol in the sausage are solved; in addition, the bamboo shoot fibers can serve as natural carriers to convey polyphenol to the colon and gives play to efficacies beneficial to intestinal flora synergistically along with dietary fibers. The particle size of the bamboo shoot fibers subjected to treatment through an integrated technique is reduced to the micron size, so that damages of a space structure of protein gel in the sausage are avoided. Furthermore, taste and flavor of the sausage product can be effectively kept, contents of the dietary fibers and polyphenol in the sausage are remarkably increased, and adsorption and protection of polyphenol can be realized through the bamboo shoot fibers, so that bioactivity is improved while the utilization rate is increased, health efficacies of the sausage product are enhanced, and a great market potential is achieved.

Description

technical field [0001] The invention relates to a sausage and a preparation method thereof, in particular to a sausage containing a bamboo shoot fiber-polyphenol compound and a preparation method thereof, belonging to the technical field of food processing. Background technique [0002] Polyphenols (Polyphenols) are important active ingredients contained in tea, fruits and vegetables, which have biologically active functions such as scavenging free radicals in the body, delaying body aging, preventing cardiovascular diseases, and preventing cancer. As an important functional active ingredient, plant polyphenols have been widely used in various foods. However, polyphenols are easily oxidized and destroyed during food production, storage and entering the human digestive system, resulting in extremely low bioavailability. [0003] Dietary fiber is another high-profile functional plant component. Agricultural product processing waste, including fruit peels, shells and seeds, ca...
