Tuna bone powder and preparation method thereof

Abstract

The present invention discloses tuna bone powder and a preparation method thereof. High-quality tuna bones are repeatedly washed clean and drained for a standby application, then a subcritical water combined microwave treatment is used to enable fish bones to be fully softened, then after the fish bones are evenly mixed with a deodorant, putting still is conducted for 10-30 min, then the deodorantis washed clean with clean water, and finally the fish bones are dried, pulverized and sterilized to obtain the tuna bone powder. The subcritical water combined microwave treatment technology is usedfor processing the tuna bones, can effectively shorten softening time, enhances a softening effect, and reduces time cost loss. At the same time, the preparation method retains calcium, phosphorus and other nutritional components in the fish bones to the maximum extent, and avoids caused loss and waste of nutrients during the softening process. In addition, after the subcritical water combined microwave treatment, the preparation method lays foundation for late-stage deodorization, drying and pulverization, can effectively release minerals of hydroxyapatite, etc. in the fish bones, significantly increases protein content in the fish bones, and enables nutrients in the fine powder to be more liable to be digested and absorbed by human body.

Description

technical field [0001] The invention belongs to the field of food processing, and in particular relates to a preparation method of tuna bone meal and the tuna bone meal prepared by the method. Background technique [0002] Due to its high nutrition and high edible value, tuna is generally processed into tuna sashimi and canned fish, which is loved by consumers all over the world; but tuna bone is one of the by-products of the tuna processing industry, because of its economic benefits Lowdown is usually discarded along with other by-products such as offal. Tuna bone meal is made from crushed tuna bone. It is rich in nutritional value and contains various nutrients such as fat, protein, calcium, and phosphorus. The ratio of calcium and phosphorus is reasonable, and it is easy to be absorbed by the human body. Adding it to food can increase food quality. The nutritional value of tuna can also be significantly improved and the utilization rate of tuna can be significantly incre...

Problems solved by technology

Although this method of softening fish bones has the characteristics of low cost and easy operation, it is easy to cause the loss of nutrients in fish bones during the treatment process. At the same time, there are problems of low softening efficiency, long time consumption, and low utilization rate, which cannot meet the needs of the industry. user needs

In addition, in previous studies, it was also found that in the process of animal osteoid processing, the dissolution of protein content has always been low, and the body has not made a major breakthrough in the absorption efficiency of bone powder, but only in the process of bone powder absorption. A lot of research has been done on the research of deodorization and odor removal
