Effect of sensory properties and health information on consumer acceptance and purchase of colorful fresh market potatoes

Creator:: Wechsler, Linda J.
Abstract:: Potato varieties characterized by non-conventional skin and flesh colors (purple, red, yellow) have the potential to revitalize consumer demand for fresh market potatoes because of their unique appearance and health benefits. Red and purple potatoes contain anthocyanins, which are flavonoids responsible for red, blue, and purple pigments in plants. Yellow...

Experimental investigation of carbon dioxide (CO₂) laser perforation as a potential skin pretreatment for sugar infusion process of frozen blueberries

Creator:: Fujimaru, Tomomi
Abstract:: The purpose of this research was to examine the feasibility of carbon dioxide (CO2) laser perforation and its potential utilization as a novel skin pretreatment for the sugar infusion process of IQF (individually quick frozen) blueberries. In the first study, IQF blueberries were treated with varying degrees of laser perforation...

Evaluation of the off-flavor in English sole (Parophrys vetulus) using descriptive analysis techniques and consumer testing

Creator:: Geise, Laura Ann
Abstract:: English sole (Parophrys vetulus) is a flatfish found in abundance in the Pacific Ocean and is part of the Pacific Northwest's and California's commercial trawl fishery. Stock levels of this fish are at all time highs but there are decreased landings due to low demand and acceptability. With new regulations...

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...

Characteristics of Northern squawfish (Ptychocheilus oregonensis) and feasibility for utilization as human food

Creator:: Lin, Dongdong
Abstract:: The characteristics of Northern squawfish (Ptychocheilus oregonensis) and the feasibility of utilization of this species for human consumption were investigated. In the first experimental phase, the iced storage characteristics of squawfish were determined. Quality changes were monitored over 24 days of storage by chemical, physical, microbiological and sensorial methods of...

Effect of salt and pH on surimi gels made from Pacific whiting (Merluccius productus)

Creator:: Chung, Yun-Chin
Abstract:: The effect of salt (0, 0.9, 1.7, 2.5%) and pH (range 4 to 10) on surimi gels made from Pacific Whiting (Merluccius productus) was investigated. Gel-forming ability was measured by the torsion test. In general, surimi gels increased in gel strength with increased pH. Breaking shear stress increased to a...

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...

Physical and chemical changes in stabilized mince from Pacific whiting during frozen storage

Creator:: Magnusdottir, Edda
Abstract:: Cryoprotection in stabilized mince from Pacific whiting (Merluccius productus) was investigated by monitoring changes in physical and chemical properties during 32 weeks of frozen storage. The effects of 4 different cryoprotectants were evaluated by torsion test, color analysis, extractability of salt soluble proteins, and formation of dimethylamine (DMA) and 2-thiobarbituric...

Effect of high pressure processing on the survival of Vibrio parahaemolyticus strains in pure culture and Pacific oysters

Creator:: Calik, Hakan
Abstract:: Different strains of Vibrio parahaemolyticus (Vp) in broth cultures and Vp-inoculated live Pacific oysters (Crassostrea gigas) were subjected to high pressure processing (HPP) at 241, 276, 310, and 345 MPa. Results showed Vp numbers were reduced by HPP in both pure culture and whole oysters. Vp inactivation was dependent on...
