Identification Of Shark Species In Commercial Products Using Dna Barcoding, Rosalee S. Hellberg, Rachel B. Isaacs, Eduardo L. Hernandez
Identification Of Shark Species In Commercial Products Using Dna Barcoding, Rosalee S. Hellberg, Rachel B. Isaacs, Eduardo L. Hernandez
Food Science Faculty Articles and Research
Sharks are harvested globally and sold in a variety of commercial products. However, they are particularly vulnerable to overfishing and many species are considered protected or endangered. The objective of this study was to identify species in various commercial shark products and to assess the effectiveness of three different DNA barcoding primer sets. Thirty-five products were collected for this study, including fillets, jerky, soup, and cartilage pills. DNA barcoding of these products was undertaken using two full-length primer sets and one mini-barcode primer set within the cytochrome c oxidase subunit (COI) gene. Successfully sequenced samples were then analyzed and identified …

The antioxidant capacity of dried Agaricus bisporus mushrooms (DAB) in beef has previously been assessed. However, interactions between lipid oxidation products, mushroom polyphenols, and bovine proteins present in beef to explain the mushroom's antioxidative effect, has not been determined. Oven-dried or lyophilized DAB with and without 15 g NaCl/kg beef (1.5%) or 20 g NaCl/kg beef (2%) were added to sarcoplasmic protein homogenates from top round beef. Malondialdehyde and volatile aldehyde binding to sarcoplasmic protein (SP) were monitored. Oven dried had 64% higher total phenolic compared to lyophilized DAB, leading to ∼50% lower malondialdehyde content in beef with oven …
Almond Milk Powder Fortification With Flaxseed Oil (Linum Usitatissimum) As An Alternative Non-Dairy Milk Powder For Infants And Toddlers, Federico Bueno
Almond Milk Powder Fortification With Flaxseed Oil (Linum Usitatissimum) As An Alternative Non-Dairy Milk Powder For Infants And Toddlers, Federico Bueno
LSU Master's Theses
Lactose intolerances in toddlers have become a major concern. Almond milk (AM) has nutritional benefits and a texture like dairy milk without the content of lactose. Because of longer stability and storage, milk is often stored in powdered form. An almond milk fortified with flaxseed oil in powdered form may be an alternative. Flaxseed oil (FO) contains high amounts of alpha-linolenic acid (ALA) which is a precursor to DHA and EPA. The objectives of this study were: the development of an AM spray-dried powder with microencapsulated FO (AMFOP), the determination of the mass and energy balance of that AMFOP production, …
Extractable And Non-Extractable Polyphenols From Mango, Yuchao Ma
Extractable And Non-Extractable Polyphenols From Mango, Yuchao Ma
Masters Theses
Polyphenol from fruits and vegetables have been proved that can lower the risk of many chronic disease. However, most studies are only focus on the extractable polyphenols right now. Non-extractable polyphenols may also have many important biological effects. The objective of this study was to find the difference between the extractable polyphenol and non-extractable by alkaline hydrolysis, acid hydrolysis and enzyme hydrolysis, compare the total phenolic content, flavonoid content and tannin content, and study their anti-inflammation effect, anti-cancer effect and antioxidant effect. The results showed that NEP alkaline hydrolysis was the best way to extract mango polyphenol. It had the …
Evaluating Consumer Sensory And Composition Attributes Of Arkansas-Grown Fresh-Market Blackberries, Aubrey N. Dunteman, Renee T. Threlfall, John R. Clark, Margaret L. Worthington

Blackberries are grown worldwide for commercial fresh markets. Three Arkansas-grown fresh-market blackberry genotypes (‘Natchez’, ‘Ouachita’, and A-2418) were evaluated for consumer sensory and compositional attributes at the University of Arkansas Food Science Department, Fayetteville. The compositional attributes of the blackberries were within an acceptable range for commercial markets (soluble solids=8.20-11.90%, pH=2.79-3.18, titratable acidity=1.09-1.32%). In terms of soluble solids to titratable acidity ratio, ‘Ouachita’ (10.92) had the highest ratio, followed by ‘Natchez’ (8.93) and A-2418 (6.25). A consumer sensory panel (n=80) evaluated fresh-market blackberry attributes using a 9-point hedonic scale for overall impression, overall flavor, sweetness, and sourness and a 5-point …
