Mid-Infrared Spectral Characterization of Aflatoxin Contamination in Peanuts
Contamination of peanuts by secondary metabolites of certain fungi, namely aflatoxins present a great health hazard when exposed either at low levels for prolonged times (carcinogenic) or at high levels at once (poisonous). It is important to develop an accurate and rapid measurement technique to …

Development of standardized dry roasting procedures for Virginia type peanuts
Peanuts are grown around the world and in United States where most peanuts are consumed after roasting. Peanuts are roasted to a specified color on L*a*b* scale as it is correlated with quality and acceptability. Two batches of Virginia type peanuts were acquired, one normal and other a high oleic …

The role of birds in spreading the Cylindrocladium Black Rot of peanuts
Bird utilization of twenty fields was observed at monthly intervals for one year, from May 1977 to April 1978. The 20 fields were located in 2 areas of southeastern Virginia. A total of 30 bird species were observed using the fields. The migratory and movement patterns of some of the species were …

Simulation of deep-bed drying of Virginia peanuts to minimize energy use
A deep-bed drying model simulating the drying of peanuts in a fixed bed is required for designing energy-efficient and automatically controlled dryers. A deep-bed drying model consists of a thin-layer drying model to calculate the moisture release from the material and a set of mass and energy …

Movement patterns and phenology of the tobacco thrips, Frankliniella fusca (Hinds), in Virginia peanuts
… tobacco thrips, Frankliniel/a fusca (Hinds), in peanuts were studied in 1990 and 1991 in the City of Suffolk, Virginia. The long-term goal was to improve our understanding of the role of tobacco thrips in the epidemiology of tomato spotted wilt virus in peanuts; the short-term goal was to develop …

The effects of the three soil-inhabiting fungi on peanuts grown under germ-free conditions
Excised peanut embryos were sterilized by treatment with 1% NaOCl tor 5 minutes, and placed in 250-ml flasks containing nutrients and expanded granular shale. Nutrients consisted of Hoagland's solution supplemented with 1% sucrose and 0.03 ppm gibberellic acid. Plants were grown for 4 weeks in …

Effects of Storage Conditions of Aspergillus Growth and Aflatoxin Production in Peanuts. A Study in Ghana
Peanuts (Arachis-hypogaea) are one of the staples in Ghana, Sub-Saharan Africa, and other developing countries. This leguminous crop is frequently contaminated with aflatoxins, which are secondary metabolites of some Aspergillus fungi, mostly Aspergillus. flavus and Aspergillus parasiticus. …

Detection of freeze damage in Virginia peanuts (Arachis hypogaea L.) by conductivity, tetrazolium, dipicrylamine, and visual tests
… been controversy over the accuracy of grading peanuts for freeze damage by United States Department of Agriculture (USDA) guidelines. Several other tests for estimating freeze damage in peanuts were investigated. The conductivity test, which measures electrolyte leakage from cells, and the …

Maximum of oil output of a treadle-powered peanut oil press
… oil is obtained by manually pressing it from peanuts. In order to more efficiently and easily express oil from peanuts, a design for a treadle-powered peanut oil press was created. My thesis work will attempt to further increase the amount of oil extracted by optimizing the design of this …

An analysis of demand and price relationships between peanuts and cashew nuts in the United States, with emphasis on the salted nut trade
This study concerns the competitive position of peanuts and cashews in the salted nut trade of the United States. The effect of the price support and production control program for peanuts is evaluated in regard to the demand and price relationships between salted peanuts and cashews. This research …
