A study of factors affecting the efficiency of maturity separation of peas by sodium chloride brine flotation

Creator:

Chavasit, Visith

Abstract:

The problem in green pea grading system by using brine flotation is loss of some less mature peas (generally regarded as higher in quality and price) in the sinker fraction (lower quality). Green peas were sampled from the production line as follows: (1) blanched but ungraded peas, (2) floater fraction,...

A study of the DNA excision repair capabilities of rainbow trout (Salmo gairdneri) exposed to dietary cyclopropenoid fatty acids

Creator:

Collier, John Mark

Abstract:

The DNA repair capabilities of rainbow trout (Salmo gairdneri) were studied vising the method of autoradiography. Trout were fed a semi-purified control diet containing 0 ppm, 50 ppm, or 300 ppm cyclopropenoid fatty acids (CPFA) for 6-9 weeks. Liver slices were prepared and exposed in vitro to a control treatment,...

Adhesive property of bacteria and its relationship to microbial spoilage of shrimp

Creator:

Smith, John B.

Abstract:

Pacific shrimp (Pandalus jordani) was washed repeatedly and the eluted bacteria were enumerated and identified. Selected isolates were tested for their adhesive properties. Washing reduced the microbial load by 3.84 to 42.04%. The bacteria which most resisted wash-off were Staphylococcus and Pseudomonas spp. The easiest to wash off was Flavobacterium...

Aflatoxin mutagenesis and metabolism and their dietary modification in rainbow trout (Salmo gairdneri)

Creator:

Coulombe, Roger A.

Abstract:

Aflatoxin B₁ (AFB₁) is a mold-produced toxin which has been shown to be a potent hepatocarcinogen in many animal species. Of the species studied thus far, rainbow trout have proven to be the most sensitive. Experiments were conducted to investigate various aspects of AFB₁ metabolism in this species, including in...

Alteration in levels and synthesis of proteins in trout hepatocytes due to dietary cyclopropenoid fatty acid[s]

Creator:

Perdew, Gary H.

Abstract:

Cyclopropenoid fatty acids (CPFA) are unique compounds that contain a highly strained and reactive cyclopropene ring structure. These compounds have been shown to cause a number of toxic effects in a variety of animals. Rainbow trout (Salmo gairdneri) have proven to be particularly sensitive to CPFA. Studies have revealed that...

An analytical and sensory evaluation of the aroma volatiles of Tuber gibbosum

Creator:

Marin, Anna B.

Abstract:

The aroma of Tuber gibbosum, a native Oregon truffle, was characterized using two distinct techniques. Volatile aroma constituents were identified by chemical analysis, and sensory characteristics were determined by examining response of the general populace to the truffle aroma. Truffle samples from four maturity ranges, as determined by microscopic examination...

An improved procedure for holding round pink shrimp (Pandalus jordani) post-catch

Creator:

Toledo-Flores, Luis Javier

Abstract:

Chilling (2-4°C) (10 min) in a solution containing 10% condensed phosphate, 5% potassium sorbate, and 0.9% citric acid (pH 6.7) stabilized round shrimp to microbial spoilage. This treatment procedure allowed refrigerated storage of round shrimp eliminating the need for ice and the accompanying deteriorative effects of water absorption and protein...

An improved solvent extraction of onion oil

Creator:

Hernandez-Molinar, Ernesto

Abstract:

A simple process to obtain onion oil by direct solvent extraction was proposed. Several solvents commonly utilized in the food industry were tested for their selectivity in the extraction of the oil of onion. Diethyl ether and methylene chloride appeared to be the most suitable solvents for the extraction operation....

An investigation of the effects of nutritional status on the action of insulin in rainbow trout (Salmo gairdneri)

Creator:

Ablett, Richard F.

Abstract:

Three studies were conducted to evaluate the relationship between insulin and nutritional parameters in rainbow trout. In the first study effects on growth parameters and tissue composition of rainbow trout were investigated following injection of bovine insulin at two dose levels every 48 hr for 56 days. In addition, [¹⁴C]-leucine...

Anthocyanin pigment, nonvolatile acid and sugar composition of red raspberry juice

Creator:

Spanos, George A.

Abstract:

Seven red raspberry (Rubus Ideaus L.) samples from Oregon, Washington, British Columbia and New Zealand were processed into juice. These, along with three juice samples supplied from West Germany were analyzed by high performance liquid chromatography, (HPLC), for nonvolatile acid, sugar, anthocyanin and anthocyanidin composition. In order to quantitate the...
