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...
Both consumer and descriptive analyses were used to study the shelf-life of packaged, roasted and ground coffee in order to evaluate the utility of using sensory data in a shelf life model, and to examine the ability of consumers to detect a difference between treated and control samples. Two types...
Machine separated flesh from American shad (Alosa
sapidissima) was evaluated for preparing heat set gel products.
Round fish frozen for 15) to 10 months at -18°C served as raw
material for processing investigations. The effectiveness of
various additives and processing procedures for improving gel
strength and sensory characteristics were determined....
In this issue, our group of winegrape researchers throughout the state has comprised a summary of the statewide incidence and damage caused by Short Shoot Syndrome and mites over the past few years. Be sure to check this out as it provides some interesting information! Also, a vineyard update has...
2020 and 2021 brought the first reported outbreaks of salmonellosis epidemiologically linked to dry bulb onions in the United States. Outbreak investigations were not able to implicate a specific source of the contamination but speculated that contaminated water was a significant contributor. The Produce Safety Rule established minimum standards for...
A partial cystatin cDNA from rainbow trout was
generated by reverse transcription polymerase chain reaction
with two degenerate primers. The partial cystatin PCR
product was 168 bp and used to screen trout liver λgt 11
cDNA library. Four positive clones were isolated and
designated as cstl, cst2, cst3 and cst4....
Mycobacterium avium subsp. paratuberculosis (MAP) is a cause of
Johne's disease (JD) in cattle and other ruminants. MAP infection in the bovine
host is not well characterized. It is assumed that crossing the bovine intestinal
mucosa is important for MAP to establish infection. MAP's ability to infect
bovine epithelial cells...
Methodology for characterization of the phenolic profile of
apple, pear and grape juice was developed. It utilized High
Performance Liquid Chromatography (HPLC) for separation of
individual phenolic compounds and Diode Array Detection for
recording the Ultra-violet (UV) spectrum of chromatographic
peaks. The high resolution achieved and the ability of recording...
Stability, substrate and inhibitor specificity and electrophoretic
properties of a crude polyphenol oxidase (PPO) preparation extracted
from d'Anjou pears (Pyrus communis L.) were investigated. Levels
of polyvinylpyrrolidone and pH of buffer for extraction were found
to affect the specific activity of the extracted enzyme. An extract
prepared with 1.5 g...
