［Objective］ To investigate the effect of garlic paste addition on volatile flavor substances and color attributes of crayfish tails, and provide a theoretical basis for flavor standardization in industrial production.［Methods］ This paper adopts gas chromatography-ion mobility spectrometry (GC-IMS ) combined with colorimetric analysis to study the characteristics of volatile components and color parameters (L*,a*,b* values ) of crayfish tails under garlic paste additions of 0%,4.4%,8.8%,13.2%,17.6%,and 22.0%. Principal component analysis (PCA ) is applied to analyze flavor differences.［Results］ Colorimetric analysis reveals that garlic paste addition significantly decreases L* from 45.69 to 34.50 and b* from 39.24 to 29.94 (P<0.05), while a* values show a significant difference under the garlic paste addition of more than 13.2% (P<0.05). A total of 53 volatile substances are identified by GC-IMS, and their total content increases gradually with the rising garlic paste addition (highest value in the 22% group at 18 749 and lowest value in the control group at 10 758). Camphene, 2-ethylbutanoic acid, 2-methylbutyl acetate, allyl isothiocyanate, and heptanal are identified as intrinsic flavor markers of crayfish meat. Key contributors to flavor include camphene, 1-heptanol, 3-pentenenitrile, 2,3-pentanedione, diacetyl, and isopropanol. PCA shows that the 13.2%~17.6% group exhibits significantly different flavor characteristics from other groups (PC1 contribution rate of 76%).［Conclusion］ Under the garlic paste addition of 8.8%~13.2%, the optimal balance between flavor and color attributes is achieved, while excessive addition of more than 17.6% results in aldehyde overaccumulation and accelerated browning.

Examining The Ligands, Location, And Function Of Toll-Like Receptor 10, Kiefer Keanu Tam

Master's Theses

Toll-like receptors are a class of innate immune pattern recognition receptors that detect pathogen-associated molecular patterns and regulate downstream inflammatory responses. Toll-like receptor 10 remains the only human TLR whose ligand specificity, cellular localization, and immunological function are not fully defined. Emerging evidence suggests that TLR10 may play an anti-inflammatory role and can heterodimerize with TLR2 to modulate immune signaling. Previous studies from our laboratory demonstrated that stimulation with heat-killed Mycobacterium tuberculosis promotes TLR2-TLR10 heterodimerization and trafficking to the cell surface. In this study, we expanded our ligand panel to include additional gram-positive bacteria, particularly anti-inflammatory probiotic species, to further …
