A Meta-Analysis Of Seafood Species Mislabeling In The United States, Sarah Ahles, Christina A. Mireles Dewitt, Rosalee S. Hellberg

Food Science Faculty Articles and Research

Seafood is vulnerable to mislabeling due to complex global supply chains, varying prices, and the similar appearance of species. While numerous studies have been published on seafood mislabeling, the focus is often on species known to be commonly substituted. Therefore, the overall mislabeling rates of seafood sold in the U.S. remain unknown, especially for the most consumed species. The objective of the current study was to compile the results of seafood mislabeling studies into a single resource to provide informative statistics on U.S. seafood mislabeling. A meta-analysis was conducted on U.S. seafood mislabeling studies that tested commercial samples of bony …

Using Bivalves As An Indicator For Fecal Bacteria, Kamala Chuss

Honors Scholar Theses

This project focuses on the integration of fecal bacteria from warm-blooded animals into bivalve tissue, and the utilization of bivalves as an indicator for fecal bacteria in waterways. Bivalves may give a more representative long-term average of fecal bacteria in water as compared to direct water testing. The primary objective is to create a standard operating procedure to use bacterial testing of bivalves as a proxy for bacteria concentration in the water. This method can be used in places where bivalves do not already exist by adding them to a body of water, or by collecting bivalves that already exist …

Food Safety, Livestock Health, And Productivity Of A Layer Farm Following Implementation Of A Certified Haccp System In Japan, Hiroshi Akaike, Makoto Nagai, Tomomitsu Alexandre Okatani, Sumalee Boonmar, Yukio Morita

The Thai Journal of Veterinary Medicine

This study examined the safety and productivity of a layer farm over a 3-year period following the implementation of a farm Hazard Analysis and Critical Control Points (HACCP) system in 2019. The critical control point was “automatic egg collection” and no deviations from critical limits were observed, indicating the eggs were safe. In addition, the egg production rate increased and the feed conversion rate decreased. In contrast, the viability after the introduction of a farm HACCP system, in which the replenishment of new hens was discontinued after forced molting, showed an increasing trend. These results suggest that the HACCP system …

Preferential Binding Of Polyphenols In Blackcurrant Extracts With Milk Proteins And The Effects On The Bioaccessibility And Antioxidant Activity Of Polyphenols, Ting Mao, Fnu Akshit, Iresha Matiwalage, Subha Sasidharan, Caren Meyn Alvarez, Philip Wescombe, Maneesha S. Mohan

Dairy Science and Food Science Faculty Publications: 2022 to Present

Milk proteins are well-known delivery agents; however, there is no clear understanding of the competitive interactions of milk proteins with polyphenols in mixed complex systems. Here, we investigate the preferential competitive interactions of different polyphenols present in blackcurrant extract with milk proteins by quantifying the protein-bound polyphenols and comparing the factors affecting these interactions. In addition, bioaccessibility and antioxidant activity were studied after in vitro gastric digestion. Our results indicated that polyphenols from blackcurrant extracts were preferentially bound to caseins more than whey proteins, with noncovalent interactions causing secondary structural changes in the protein. The hydrophobicity and the charge of …

The Effect Of Soluble Soybean Polysaccharide Addition To Permeate Concentrate On Lactose Crystallisation, Growth And Recovery During Lactose Manufacturing, Venkateswarlu Sunkesula, Prafulla Salunke, Lloyd E. Metzger

Dairy Science and Food Science Faculty Publications: 2022 to Present

Lactose is manufactured from permeates of cheese whey, milk protein concentrate and a mix of both using a crystallisation process. Several factors, such as solute supersaturation, cooling rate and impurities, influence lactose crystallisation. This study focussed on the effect of soluble soybean polysaccharides (SSPS) on crystallisation during lactose manufacture from concentrated permeate solutions by evaluating lactose crystal growth and recovery with and without SSPS addition. Adding 0.1% (w/w) SSPS resulted in a significant difference (P > 0.05) in lactose crystal size and yield. The results suggest that using SSPS during lactose manufacturing from permeate concentrates could influence lactose crystallisation and recovery

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Lotic waterways are vital for habitat, food, water, and flood protection, but urbanization poses a major threat to their integrity. Runoff from urban surfaces leads to pollution, flashiness, loss of biodiversity, and other symptoms, also known as Urban Stream Syndrome (USS). Streams can be restored in order to combat USS, but most restorations are not monitored, so their long-term effectiveness is unknown. This study quantitatively evaluated a decade-old stream restoration in Fayetteville, Arkansas, to assess its effectiveness in combating USS and achieving set restoration goals, and to gain insights for future restoration projects. Restoration goals included decreasing erosion and sedimentation, …

Evaluating Efficiency And Accuracy Of Three Texture Analysis Methods For Blackberry Fruit, Rhys M. Brock, Carmen Johns, Katelyn Lust-Moore, Margaret Worthington

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

A major objective of the University of Arkansas System Division of Agriculture (UADA) Fruit Breeding program is to improve the texture of blackberry (Rubus subgenus Rubus Watson). Blackberry varieties with improved fruit firmness transport and store well and may maintain superior quality under challenging postharvest conditions than softer varieties. Increased firmness may also make cultivars less susceptible to red drupelet reversion (RDR), a postharvest disorder of blackberries in which fully black drupelets revert to red after harvest. This research project aims to assess the efficiency and accuracy of three methods applied in evaluating blackberry firmness. The study compares instrumental analysis …
