While some reports show that physical characteristics of the baru fruits (Dipteryx alata Vog.) differ within and among the Brazilian Savanna regions, a study shows that there are differences in the nutritional composition of baru almonds from different trees from the same Savanna area. It is unknown, however, whether the Savanna’s region influences the nutritional quality of this native almond....

The aim of this study was to determine if taste interactions occur when bitter stimuli are mixed. Eight bitter stimuli were employed: Denatonium benzoate (DB), (L-phe), Ranitidine-HCl, and Tetralone®. The first experiment constructed individual psychophysical curves for each subject (n=19) for each compound to account for individual differences in sensitivities when presenting bitter compounds ...

Taste plays a crucial role in the life of honey bees as their survival depends on the collection and intake of nectar and pollen, and other natural products. Here we studied the tarsal taste of honey bees through a series of behavioral and electrophysiological analyses. We characterized responsiveness to various sweet, salty and bitter tastants delivered to gustatory sensilla of the fore tarsi....

The sense of taste is critical in determining the nutritional suitability of foods. Sweet and bitter are primary taste modalities in mammals, and their behavioral relevance is similar in flies. Sweet taste drives the appetitive response to energy sources, whereas bitter taste drives avoidance of potential toxins and also suppresses the sweet response [1, 2]. Despite their importance to survival...

BACKGROUND Bitter taste is the primary culprit for rejection of pediatric liquid medications. We probed the underlying biology of bitter sensing and the efficacy of two known bitter blockers in children and adults. METHODS A racially diverse group of 154 children (3-10 years old) and their mothers (N = 118) evaluated the effectiveness of two bitter blockers, sodium gluconate (NaG) and monosod...

Food contains complex blends of structurally diverse bitter compounds that trigger bitterness through activation of one or more of the ∼25 human TAS2 bitter taste receptors. It remains unsolved, however, whether the perceived bitterness of binary bitter-compound mixtures can be considered an additive function of all bitter-inducing chemicals in the mouth, suggesting that little mutual interacti...

three experiments were conducted to evaluate the nutritional value of bitter vetch. experiment 1 was conducted to determine the metabolisable energy content of bitter vetch. sixteen adult leghorn roosters were used. forty grams of bitter vetch were precision-fed individually to 12 roosters. in addition, 4 birds were not fed and served as a control treatment in the measurement of metabolic fecal...

the quality evaluation of agricultural products is one of the key factors in promoting their quality. in this study, a method based on combined image processing technique and artificial neural network was presented. separation of touching almonds under different positions is a very important step in design of grading devices. in this study, an image processing algorithm based on extracting crit...
