The composition of amylopectin is the determinant of rice eating quality under certain threshold of protein content and the ratio of amylose and amylopectin. In molecular biology level, the fine structure of amylopectin is determined by relative activities of starch branching enzyme (SBE), granule-bound starch synthase (GBSS), and soluble starch synthase (SSS) in rice grain under the same ADP-G...

In-home evaluations of the M. vastus lateralis, M. rectus femoris, M. semimembranosus, and M. adductor (n=266) muscles that were either blade tenderized, enhanced with a salt and phosphate solution, or served as a control (no tenderization or enhancement treatment) were conducted. Consumers (n=261) cooked these steaks and were asked to document cooking method and degree of doneness, and provide...

The neurosteroid allopregnanolone may increase feeding by altering food palatability; however, it may also increase feeding by reducing anxiety (neophobia). Moreover, it is unclear whether this induced hyperphagia is selective to safe, palatable foods only. Male rats were injected with allopregnanolone 20 min prior to behavioral testing. The taste reactivity test was used to examine possible sh...

The pet food industry continues to grow steadily as a result of new innovative products. Quality control and product development tests for pet foods are typically conducted through palatability testing with dogs and cats. Palatability is the measure of intake of a food that indicates acceptance or the measure of preference of one food over another. Pet food palatability is most commonly measure...

Benzodiazepines such as chlordiazepoxide (CDP) promote feeding in a number of species. This effect has been interpreted generally to be an indirect consequence of benzodiazepine anti-anxiety action, although some have questioned whether it might not reflect instead a direct action upon the reinforcing properties of foods. The present study employed a behavioral measure that can discriminate bet...

this research was conducted to recognize sibak-sardab watershed rangeland potentials, evaluate and determine of suitability classes for sheep grazing. in this research, we used the proposed method of fao (1992) and for information layers crossing used in geographical information system (gis). in this research, sensitivity to erosion, water resources and forage production are three basic compone...

The effects of 19 meals of different caloric content on slides on palatability and hypothetical duration of consumption were investigated in 7 patients with anorexia nervosa, 17 patients with bulimia nervosa at the beginning and after 8 weeks of hospital treatment. Nine healthy females served as controls. At the beginning of treatment, palatability of low caloric food was significantly higher a...

The taste of foods, in particular the palatability of these tastes, exerts a powerful influence on our feeding choices. Although the lateral hypothalamus (LH) has long been known to regulate feeding behavior, taste processing in LH remains relatively understudied. Here, we examined single-unit LH responses in rats subjected to a battery of taste stimuli that differed in both chemical compositio...

Feeder steers (n=471) were fed for 100, 130 or 160 days, then slaughtered, and carcass grade data were collected. A wholesale rib was removed from each carcass, vacuum packaged, and aged for 12 to 14 days, and steaks were obtained. Palatability of the steaks generally increased as marbling score increased; however, the differences in palatability associated with each successive increase in marb...
