Defatted superfine fresh bone meal and uses thereof

Abstract

The invention provides degreased superfine fresh bone powder, which is applied in the fields of foods, functional foods and medicines. The degreased superfine fresh bone powder has the characteristics of high protein, high calcium, a small amount of fat, and superfine grain size. A technical process comprises the following steps: cleaning fresh animal bones; breaking the bone via a brute force, carrying out pulverization, degreasing, drying and attritioning to obtain the degreased superfine fresh bone powder. Compared with the prior art, the technical process adjusts a technical route, and adopts a processing method integrating pulverization, chemical degreasing, drying and attritioning, thereby ensuring that the production is easy to realize, the energy consumption is reduced, and the product is safe and sanitary, and is easily stored. The degreased superfine fresh bone powder can be widely applied to the calc reinforcement for meat products, cake and condiments.

Description

technical field [0001] The invention relates to the field of food processing, in particular to a degreased superfine fresh bone powder using animal bones as a raw material and its application. Background technique [0002] Livestock and poultry bones account for about 20%-30% of animal weight, and can produce nearly 20 million tons of livestock and poultry bones every year. Ribs, cavity bones, and some white strips of meat are sold directly with bones, and large stick bones of cattle are used to prepare gelatin or For extracting bone extract and bone broth, there are still a large number of livestock and poultry bones that have not been effectively utilized in my country, and there are still sufficient livestock and poultry bone resources waiting to be developed. [0003] The processing and utilization of livestock and poultry bones has always been the focus of research in the industry, especially in reducing environmental pollution, realizing resource reuse, and increasing t...

AI Technical Summary

Problems solved by technology

This method has three disadvantages: first, the raw material is only pig scapula, and other kinds of livestock and poultry bones other than pig scapula cannot be fully utilized, so it has certain limitations in the source of aggregate

The second is that there is no degreasing process. The bone powder contains 5% to 15% fat, and the bone fat contains a lot of unsaturated fatty acids, which are easy to oxidize and deteriorate during processing and storage, which will affect the flavor, quality and shelf life of the product.

The third is that the existence of a large amount of fat brings great difficulties to ultra-fine grinding, which requires high grinding equipment and system temperature.

In this way, the processing cost per kilogram increases by 50% to 80% compared with normal temperature crushing, and a lot of energy is wasted

Therefore, the method disclosed in this patent application not only has a very high processing cost, but also leads to a high price of the finished product, which cannot fully satisfy people's needs.
