Method using steam explosion technique to prepare chicken bone soup-stock

Abstract

The invention provides a method using a steam explosion technique to prepare chicken bone soup-stock. The method comprises the following steps of (1) cleaning chicken bone, putting into a steam explosion machine, closing and sealing a material charging valve and a material charging valve of the steam explosion machine, setting the steam pressure of the steam explosion machine to 2.0 to 3.5MPa, and the pressure maintaining time to 200s to 900s, automatically opening the material discharging valve, enabling the chicken bone to instantaneously spray and explode from a sample chamber into a collection chamber, and converting the chicken bone into milky white slurry and bone residues; (2) centrifuging and separating the milky white slurry and the bone residues in step (1), and collecting a supernatant, so as to obtain a chicken bone steam explosion treatment raw soup liquid; (3) performing vacuum concentration on the chicken bone steam explosion treatment raw soup liquid obtained in step (2), so as to obtain the chicken bone soup-stock. The method has the advantages that the technology is simple, the operation is easy, and the production capacity of equipment is high; the raw material is thoroughly treated, the extracting rate is increased, the production cost is reduced, and the enterprise profit is improved.

Description

technical field [0001] The invention mainly relates to the technical field of food and its preparation method, in particular to a method for preparing chicken bone broth by steam explosion technology. Background technique [0002] "Bone essence is in the soup", animal bones contain a variety of nutrients, the protein content is about 10%, the fat content is about 13%, the calcium content is about 4%, and the phosphorus content is about 2%. The content of iron, calcium and phosphorus is much higher than other foods. In particular, the nutrients in bone broth are easier to digest and absorb than plant foods, and have health benefits such as strengthening bones, increasing blood, anti-aging, and beautifying the skin. . Calcium in bones cannot be dissolved. No matter how high the temperature is or how long it takes, the calcium in animal bones will not decompose, but will have an adverse effect on the nutrients in bones. [0003] In the processing and preparation of high-quali...

Problems solved by technology

However, in actual production, the meat on the bones cannot be completely removed, and the attached meat increases the difficulty of crushing, and the current crushing technology cannot process the bones into a state of extremely small particle size and uniform particle distribution; (3) Boiling, the temperature is 100-130°C, the time is 3-12 hours

Long-term high-temperature and high-pressure extraction not only causes the loss of nutrition, but also destroys the stability of the product. At the same time, it increases the fishy smell of the product, making the umami taste unbalanced and the fragrance not lasting.
