The invention discloses a method for preparing slowly digestible wheat starch through the coordination of a biological enzyme and low-temperature freeze-thawing, which comprises the following steps: performing debranching treatment on starch through a biological enzyme method; forming a structure the most of which is in the form of a compact perfect crystal under retrogradation action; and performing low-temperature repeated freeze-thawing treatment to destroy the perfect crystal of the starch so as to form a structure the most of which is in the form of an imperfect crystal, thus increasing content of the slowly digestible starch.

The present invention describes the use of fish protein (namely cod protein) and soy protein to improve the peripheral insulin resistance in a human or non-human animal. Fish and soy protein were administered to rats submitted to high-sucrose or high-fat/sucrose diets, which are animal models for diabetes. It was found that fish and soy protein efficiently control glucose utilization, and that fish protein is particularly effective in muscle tissue. This effect is not observed when rats are given casein. Fish and soy protein are therefore promising for controlling insulin-resistance, diabetes and complications resulting therefrom, such as obesity.

This invention relates to the production of succinic acid and other chemicals derived from phosphoenolpyruvate (PEP) by fermentation with a microorganism in which the fermentation medium contains one or more sugars, and in which one or more of the sugars is imported into the cell by facilitated diffusion. As a specific example, succinic acid is produced from a glucose-containing renewable feedstock through fermentation using a biocatalyst. Examples of such a biocatalyst include microorganisms that have been enhanced in their ability to utilize glucose as a carbon and energy source. The biocatalysts of the present invention are derived from the genetic manipulation of parental strains that were originally constructed with the goal to produce one or more chemicals (for example succinic acid and/or a salt of succinic acid) at a commercial scale using feedstocks that include, for example, glucose, fructose, or sucrose.
