Efficacy of water, sodium hypochlorite, peroxyacetic acid, and acidified sodium chlorite for reducing microorganisms on in-shell hazelnuts

Creator:: Weller, Lisa D.
Abstract:: Hazelnuts are commonly consumed raw and are valued for their numerous health benefits and antioxidant properties. Increased foodborne illness outbreaks associated with Salmonella and Escherichia coli O157:H7 contamination of tree nuts and peanuts generate a need for improving agricultural sanitation procedures. Food-safe chemical sanitizers have shown promise for reducing pathogenic...

Development and characterization of shelf-life and sensory properties of restructured albacore tuna (Thunnus alalunga) rolls

Creator:: Roblero, Josef G.
Abstract:: Albacore tuna (Thunnus alalunga) rolls were developed using two albacore meat levels and three different treatment combinations. Albacore meat levels of 82 and 88% (Alb82 and Alb88) of the total weight formulation were examined. The different treatments consisted of 0.3% sodium tripolyphosphate (STPP), 0.3% STPP plus nitrites (150 ppm), and...

Extraction and production of n-3 polyunsaturated fatty acid concentrate from Pacific sardines (Sardinops sagax)

Creator:: Okada, Tomoko
Abstract:: Intrinsic characteristics of Pacific sardines were determined. The lipid content in sardines was initially low (6.79%) in the beginning ofthe season, increased to 22.95% in mid-August, and decreased slightly by the end of September. An inverse correlation (R² = -0.90) was found between lipid and moisture content. Analysis showed that...

Application of ozone as a disinfectant for commercially processed seafood

Creator:: Hansen, Jenny K.
Abstract:: Pacific oysters (Crassostrea gigas), Alaska pink salmon (Oncorynchus gorbuscha) roe and chum salmon (Oncorynchus keta) fillets were treated with aqueous ozone in both pilot plant and commercial settings to determine its effect on shelf-life and microbial changes. The microbial quality was analyzed by conducting pyschrotrophic and coliform plate counts on...
