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 …

Catfish belong to the order Siluriformes and include both the Ictaluridae and Pangasiidae families. However, U.S. labeling laws require only species of the family Ictaluridae to be marketed as catfish. The lower production price of Pangasiidae, combined with changes in regulations over time, have resulted in high potential for species substitution and country of origin mislabeling among catfish products. The objective of this study was to conduct a market survey of catfish products sold at the U.S. retail level to examine species mislabeling and compliance with Country of Origin Labeling (COOL) regulations. A total of 80 catfish samples were collected …
