Effects of texture modification on the flavor of foods for elderly people with dysmasesis

The aroma and flavor of food before and during eating is a major determinant of the pleasure which drives us to eat. The aim of this study was to investigate how texture modification influences the aroma and flavor of two types of texture-modified teriyaki-based salmon foods (chopped salmon teriyaki and steamed salmon teriyaki-paste) as compared to original salmon teriyaki using gas chromatographyolfactometry and retronasal olfactometry analyses. The results indicated that the odor of soy sauce was weaker in the modified foods as compared to the original, with the past having even less odor than the chopped salmon teriyaki. The sensory evaluation corresponded with the gas chromatography results, and showed that odor was an important factor contributing to preference. Steamed salmon teriyaki-paste is suitable for elderly people with dysmasesis because it is easy to chew and swallow ; thus, optimal cooking conditions to improve its odor should be developed.研究ノー

A Molecular Design towards a Highly Amphoteric and Polar Molecule (HAPM) to Assemble Novel Organic Solid-State Structures (INTERFACE SCIENCE-Molecular Aggregates)

A molecular design towards a highly amphoteric and polar molecules (HAPM) to fabricate a novel molecular assembly with notable electronic properties is proposed. This design stresses the combination of electrondonating and accepting segments with a pseudo-delocalized π-electron system. To examine the suggested contrivance, 2-(4-dicyanomethylenecyclohexa-2,5-dienylidene)-4,5-ethylenedithio-1,3-dithiole, 1, was designed and synthesized as a test molecule. Results from semiempirical MO calculations and several kinds of experiments imply most characteristics expected for HAPM in principle

The chemical compound bubblin induces stomatal mispatterning in Arabidopsis by disrupting the intrinsic polarity of stomatal lineage cells

Stem cell polarization is a crucial step in asymmetric cell division, which is a universal system for generating cellular diversity in multicellular organisms. Several conventional genetics studies have attempted to elucidate the mechanisms underlying cell polarization in plants, but it remains largely unknown. In plants, stomata, which are valves for gas exchange, are generated through several rounds of asymmetric divisions. In this study, we identified and characterized a chemical compound that affects stomatal stem cell polarity. Highthroughput screening for bioactive molecules identified a pyridinethiazole derivative, named bubblin, which induced stomatal clustering in Arabidopsis epidermis. Bubblin perturbed stomatal asymmetric division, resulting in the generation of two identical daughter cells. Both cells continued to express the stomatal fate determinant SPEECHLESS, and then differentiated into mispatterned stomata. Bubblin-treated cells had a defect in the polarized localization of BREAKING OF ASYMMETRY IN THE STOMATAL LINEAGE (BASL), which is required for asymmetric cell fate determination. Our results suggest that bubblin induces stomatal lineage cells to divide without BASL-dependent pre-mitotic establishment of polarity. Bubblin is a potentially valuable tool for investigating cell polarity establishment in stomatal asymmetric division
