  • Descriptive analysis of Pinot noir juice and wine qualities

    Creator:
    Ludwig-Williams, Nancy
    Abstract:
    The overall purpose of this study was to develop sensory evaluation methodology whereby wine quality can be predicted from juice quality. Descriptive analysis was used by a trained panel to describe Pinot noir juice and wine from three sources. From each source, one wine and four juice samples (a control...

  • Financial recordkeeping practices of self-employed dietetic practitioners

    Creator:
    Cox, Nancy R.
    Abstract:
    The practice of dietetics has changed over the past several years to include an increasing number of dietitians working in private practice. The 1986 census of The American Dietetic Association identified 2,383 (4.3%) of the membership as active in the Consulting Nutritionist in Private Practice group. Private practice opportunities have...

  • Textural and electrical properties of Pacific whiting surimi under ohmic heating

    Creator:
    Yongsawatdigul, Jirawat
    Abstract:
    Feasibility of ohmic heating to overcome gel-weakening in Pacific whiting surimi was investigated. An ohmic heating apparatus was developed using two rhodium-coated stainless steel electrodes inside a polyvinyl chloride (PVC) tube, a variable transformer, and voltage and current transducers. Rapid heating associated with the ohmic process quickly inactivated endogenous proteinase(s),...

  • 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...

  • The significance of glutathione conjugation for aflatoxin B₁ metabolism in rainbow trout and coho salmon

    Creator:
    Valsta, Liisa M.
    Abstract:
    In rodent models as well as in fish models there are significant species differences in the susceptibility toward aflatoxin B₁ (AFB₁) carcinogenesis. Mouse is less susceptible toward AFB₁ carcinogenesis than rat. Researchers have come to the conclusion that the lower susceptibility of mice is not a result of less effective...

  • Characterization of Pacific whiting protease and food-grade inhibitors for surimi production

    Creator:
    Weerasinghe, Vasana C.
    Abstract:
    Cathepsin B was the most active cysteine proteinase in the Pacific whiting (Merluccius productus) fish fillet, and cathepsin L in surimi when the activities of the most active cysteine proteinases (cathepsin L, B, and H) were compared. Cathepsin L showed maximum activity at 55°C in both fish fillet and surimi,...

  • Biological preparation of ¹⁴C labeled aflatoxin

    Creator:
    Schoenhard, Grant Louis
    Abstract:
    Selected parameters that affect crude toxin production in both primary culture (growing cell culture) and resting culture were examined during efforts to produce sufficient crude toxin for purification. The parameters included carbohydrate and label source and concentration, cell concentration, incubation time and temperature and shaker speed. A higher yield of...

  • Utilization of wastes from Pacific whiting surimi manufacturing : proteinases and protein hydrolysate

    Creator:
    Benjakul, Soottawat
    Abstract:
    Both liquid and solid wastes from Pacific whiting surimi manufacturing were characterized and value-added products were recovered. A proteinase in surimi wash water (SWW) was determined to be cathepsin L with Mr 54,200 on SDS-substrate gel. Heat treatment and acidification shifted the activity zone to M [subscript r] 39,500. No...

  • Kinetic properties and characterization of purified proteases from Pacific whiting (Merluccius productus)

    Creator:
    Wu, JuWen
    Abstract:
    Kinetic properties of the two proteases, causing textural degradation of Pacific whiting (Merluccius productus) during heating, were compared and characterized with the synthetic substrate, Z-Phe-Arg-NMec. Pacific whiting P-I and P-II showed the highest specificity on Z-Phe-Arg-NMec, specific substrate for cathepsin L. The K [subscript m] of preactivated P-I and P-II...

  • The effects of cyclopropenoid fatty acids on the growth, blood lipids, and viral infectivity of White Leghorn chickens

    Creator:
    Swanson, Joy Emily
    Abstract:
    Three studies were designed to evaluate the promoting effect of cyclopropenoid fatty acids (CPFA) on avian myeloblastosis virus (AMV) infection in White Leghorn chickens. In the first study effects on growth parameters, blood serum and erythrocyte lipid composition of White Leghorn chickens were investigated at 100 ppm and 300 ppm...
