1. Field of the Invention
The present invention relates to a meat-fat substitute, and in particular relates to a meat-fat substitute having low calories, and the appearance and taste/texture of original fat, wherein the meat-fat substitute is thermo-irreversible.
2. Description of the Related Art
Clinical research verifies that fat, saturated fatty acid, cholesterol, etc. in one's diet relates to weight gain, type II diabetes, cardiovascular disease and some cancers. The World Health Organization (WHO) suggests that the daily dietary intake of fat should be present in the amount of 15-30% of total caloric intake, wherein saturated fatty acid should not be more than 10%, trans fatty acid should be lower than 1%, and cholesterol should be lower than 300 mg. However, the fat content of common meat products are generally between 20-50%.
In order to solve the problem of excess fat contained in meat products, there have been many technologies related to the formation of a low-fat meat product.
U.S. Pat. No. 5,603,973 discloses that one or more dextrin (glucose equivalent of each is less than 20) are embedded in sodium alginate, gum, pectin or a konjac gel matrix to manufacture an animal fat substitute. However, an initial step for mixing each raw material mentioned above needs to be performed at 73-95.
JP Patent Publication No. 2003-204772 discloses that colloid particles composed of water, fat, collagen hydrolyte and a polysaccharide thickener are mixed with a sausage composition, and then mixed with konjac gel to improve the chewing texture for low-fat sausages.
However, the above mentioned technologies have the problems of minute and complicated forming process and/or not low enough fat content for products, and shape change at high temperatures. Therefore, a novel substitute for the fat found within meat is needed, wherein the meat-fat substitute has the advantages of a simple process, low calories, low fat and shape consistency at high-temperature cooking.
The invention provides a meat-fat substitute, the forming composition thereof comprising: at least one edible gum; at least one starch; and water, wherein the at least one edible gum is present in an amount of about 0.5-20 parts by weight, the at least one starch is present in an amount of about 0.5-10 parts by weight and the water is present in an amount of about 60-99 parts by weight.
The invention further provides a method for forming a meat-fat substitute, comprising: (a) mixing at least one edible gum, at least one starch and water to form a mixture, wherein the at least one edible gum is present in an amount of about 0.5-20 parts by weight, the at least one starch is present in an amount of about 0.5-10 parts by weight and the water is present in an amount of about 60-99 parts by weight; and (b) heating the mixture to clot the mixture to form a meat-fat substitute.
A detailed description is given in the following embodiments with reference to the accompanying drawings.
The present invention can be more fully understood by reading the subsequent detailed description and examples with references made to the accompanying drawings, wherein:
The following description is of the best-contemplated mode of carrying out the invention. This description is made for the purpose of illustrating the general principles of the invention and should not be taken in a limiting sense. The scope of the invention is best determined by reference to the appended claims.
In one aspect of the present invention, the present invention provides a meat-fat substitute. The “meat-fat substitute” mentioned herein is able to be generally called “fat meat”. In addition to having the appearance and texture of the original fat, the meat-fat substitute provided by the present invention has the advantages of low calories and low fat.
In one embodiment, a forming composition for the meat-fat substitute mentioned above may comprise, but is not limited to, at least one edible gum, at least one starch and water. In the forming composition mentioned above, the at least one edible gum may be present in an amount of about 0.5-20 parts by weight, the at least one starch may be present in an amount of about 0.5-10 parts by weight and the water may be present in an amount of about 60-99 parts by weight.
The at least one edible gum may comprise curdlan, locust bean gum, carrageenan, gellan gum, xanthan gum, guar gum, gelatin, sodium alginate or the combination thereof, but is not limited thereto. In one embodiment, the at least one edible gum consists of curdlan and locust bean gum. Curdlan is a polysaccharide polymer composed of (1-->3)-β-glucan. β-glucan is considered to be a substance that is not easy to digest; a cellulose which is not easily metabolized by the digestive tract and hard to dissolve, and thus will not produce calories. Accordingly, curdlan can be applied to dietary calorie control and control of obesity. In addition, locust bean gum derives from locust bean pods. The locust bean pods are subjected to a pulverizing process, the beans removed and then subjected to a heating process, and locust bean gum is obtained accordingly. Locust bean gum, a tasteless, white powder, is a polysaccharide formed by galactose bonding to mannoside, and the molecular weight thereof is about 300,000 Daltons. Locust bean gum is an excellent thickener and stabilizer. Dried locust bean gum is capable of absorbing 50 times its weight in water, and dried locust bean gum dispersed in cold water and heated is capable of becoming a uniform, transparent solution. Locust bean gum is able to cause a synergistic effect with other natural gum, and that substantially enhances its properties of viscosity and gel formation.
