Food and Machinery

［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.

(Re)Claiming Homeplace: Dance As Embodied Resistance & Healing For Health & Spatial Justice, Preeya G. Kannan

University Honors Theses

This thesis argues that dance functions as both an upstream public health intervention and a form of radical spatial resistance; creating healing, agency, and belonging among historically marginalized communities. Drawing on bell hooks' concept of homeplace, Jasbir Puar's assemblage theory, Nancy Krieger's eco-social theory, and Katherine McKittrick's Black geographies, I position the body as both an ecological and political landscape shaped by histories of colonialism, racial capitalism, displacement, and resilience.

Through this community-based participatory research study, Homeplace, I explore dance as a form of social prescription that centers liberation rather than pathology. Movement is often reduced in public health discourse …
