［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.

Department of Agricultural Economics Faculty Publications
Many topics in the behavioral sciences and epidemiology require researchers to directly observe entities (e.g., individuals, households) over a long time to identify lasting effects. Long-term panel data collection is more common in high-income countries than in small-scale rural societies (SSRS) of low-income countries. SSRS are mobile, nature-dependent, linguistic minorities, and highly autarkic. Analyzing such data using a life-course perspective can help uncover patterns that align or upend what we know from high-income countries. This study a) reviews long (>∼10 year) panels in SSRS (n = 9), b) extends the analysis to cover somewhat comparable societies of smallholders (n …

The Cooperative Extension Service (CES) relies on systematic needs assessments to guide program development; yet, traditional approaches often depend heavily on stakeholder input and professional judgment, offering limited insight into consumer level needs. This mixed methods study explored Google Trends as a complementary, consumer driven data source for assessing Family Resource Management (FRM) needs within the Arkansas CES. Grounded in Witkin and Altschuld’s three level needs assessment framework and Uses and Gratifications Theory, the study integrated three data sources representing stakeholders, service providers, and consumers: (1) Family and Consumer Sciences (FCS) advisory committee reports, (2) survey of Family Consumer Science …

Unveiling Factors Influencing Extract Yield From Milled Rice In Brewing, Matthew Aitkens
Graduate Theses and Dissertations
Rice (Oryza sativa L.) presents a locally sourced, climate-resistant starch source for the brewing industry. As barley faces increased uncertainty due to rising temperatures, Arkansas-grown rice offers a more stable and cost-effective alternative starch source. However, the use of milled adjunct rice by brewers has remained limited, largely due to knowledge gaps about cultivar-specific properties relative to brewing. Chapter 1 provides an overview of rice as a brewing adjunct, reviewing the physiochemical properties important to brewing success. These properties include kernel size, kernel breakage, amylose content, and gelatinization temperature. Mashing strategies for multiple different brewing layouts are overviewed, showing practical …

Validation Of Rice Tissue Sampling For In-Season Nutrient Management Of Nitrogen, Phosphorus, And Potassium, Tanner Smith
Graduate Theses and Dissertations
Nitrogen (N), phosphorus (P), and potassium (K) are the 3 most important nutrients involved in rice (Oryza sativa L.) growth and development. Tissue sampling has been proven to be a potential tool to provide inseason information about plant nutrient concentrations at specified timings and growth stages. With increased interest in tissue sampling and improving nutrient management effectiveness, more information is needed to validate plant tissue concentrations at which additional fertilizer inputs may be warranted. Experiments were conducted in 2024 and 2025 at the Rice Research and Extension Center (RREC) near Stuttgart, Ark.; Pine Tree Research Station (PTRS) near Colt, Ark.; …
