Washed deboned meat having high protein recovery

Abstract

Deboned meat is subjected to processing in a surimi-type procedure in order to substantially reduce the heme content and thus the color intensity of the deboned meat, with bone marrow components and fat also being removed. When desired, the washed meat is subjected to dewatering, such as by pressing, in order to provide a color and fat reduced deboned meat. Multiple-stage separation is practiced, and the protein yield of the washed meat is advantageously elevated.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]This invention generally relates to improving deboned meat sources. These deboned meat sources are washed and filtered to remove undesirable attributes. More particularly, the invention relates to enhancing deboned meat while enhancing protein yield and minimizing protein waste. The washed deboned meat is suitable for use as a light-colored meat source for a variety of food products.[0003]2. Description of Related Art[0004]In meat processing plants, efforts are made to recover as much meat product as possible. One aspect of meat conservation in this regard is by practicing so-called deboning procedures. Deboning equipment is well-known in the art. Suitable equipment is available from Beehive, Inc. Illustrative of this technology are the processes and equipment that are shown in Beehive U.S. Patent No. Re. 32,060, U.S. Pat. No. 5,667,435, and U.S. Pat. No. 5,813,909. Each of these patents is incorporated by reference her...

AI Technical Summary

Benefits of technology

[0012]In accordance with the present invention, deboned meat is slurried and subjected to liquid-solid separation action which is carried out in multiple stages with separation interfaces of different respective porosities that decrease in pore size in the downstream direction. A deboned meat which is lighter in color and lower in fat content than the initial deboned meat is thus provided. The resulting enhanced deboned meat retains a high percentage of protein present in the initial deboned meat. In an alternate embodiment, the enhanced deboned meat is dewatered, such as by pressing, in order to provide a deboned product having a desired water content which is lower than that of the enhanced deboned meat. Preferably, this embodiment includes recycling a press residue component into the liquid-solid separation equipment whereby protein which made its way into the press residue during the pressing operation is subjected to liquid-solid separation in order to recover protein therefrom and enhance the yield of protein present in the dewatered deboned meat.

[0013]A general aspect or object of the present invention is to provide deboned meat which exhibits reduced coloration and / or odor and reduced fat while having an enhanced protein yield.

[0014]Another aspect or object of the present invention is that it provides a method for enhancing protein yield while preparing a surimi-type of deboned meat which can be dewatered in order to provide a deboned meat having a desired water content.

[0015]Another aspect or object of this invention is that it provides deboned meat which is upgraded in quality and appearance so as to be suitable for applications of higher value than typical deboned meat.

[0016]Another aspect or object of the present invention is that it is able to transform a poultry meat byproduct into meat material having improved composition, appearance and value for use in restructured poultry-based or poultry-including food products.

Problems solved by technology

While deboning equipment and processes typically do an excellent job of this type of separation, the resulting edible components often are not suitable for use in many applications without further processing.

This approach has the disadvantage of subjecting the meat protein to harsh acidic conditions.

With these types of processes, substantial quantities of protein are lost.

Filtering proposals have been made, but these are not suitable for large-scale commercial meat processing operations.

An example of the latter is the use of cheesecloth, which is not a suitable alternative in large scale operations where high flow through rates and economies of scale are essential.
