Pasteurization radiation offers a new means of extending the
refrigerated storage life of foods. This procedure avoids many of
the undesirable changes which result when sterilization radiation is
used and still eliminates most of the spoilage organisms.
Shrimp was treated with 5 ppm chlortetracycline and subjected
to pasteurization levels of...
The over-tenderization of irradiated-sterilized meat is one
of the more important adverse effects resulting from the use of
irradiation for the preservation of meat. Although research has
been reported on the activity and effect of the inherent proteolytic
enzymes of irradiated meat, very little work has been directed toward
the...
Compounds belonging to the vitamin K family possess anti-hemorrhagic
property, and are used in treating patients suffering
from hypoprothrombinemia and obstructive jaundice. Some of
these compounds also exhibit marked antimicrobial activity toward
various microorganisms. Vitamin K₅, 4-amino-2-methyl-
1-naphthol hydrochloride, a water-soluble analog of vitamin K
has been shown to possess...
The storage life at 43°F of ground dover sole fillets (Microstomas pacificus) was determined microbiologically after treatment with
ionizing radiation and antimicrobial agents. Sodium benzoate, potassium
sorbate and the sodium salts of the methyl and propyl esters
of parahydroxybenzoic acid (MPB and PPB) all approximately doubled
the refrigerated storage life...
The two naturally occurring cyclopropene fatty acids, sterculic
and malvalic, have been synthesized. The cyclopropene ring was
made by inserting a methylene unit into an acetylenic linkage.
The synthesis of methyl sterculate was repeated using diethyl
aluminum chloride, diazomethane, and methyl stearolate.
Methyl malvalate was totally synthesized. Diethyl malonate
was...
Certain chlorinated insecticides can be identified by electron capture gas-liquid chromatographic (EC-GLC) analysis of the prepared sample before and after treatment with ultraviolet irradiation, Upon U.V. treatment, characteristic degradation products arise from the insecticides investigated. Comparison of the degradation pattern obtained by EC-GLC of unknown and authentic insecticides provides an...
Effects of high temperature aging upon certain characteristics
of bovine l. dorsi muscle were studied. Paired wholesale ribs of
carcasses were obtained subsequent to slaughter. The left rib of
each pair was held at 30°C for 24 hours, then stored at 3°C.
Analogous right ribs were immediately stored at 3°C....
Diets containing cyclopropenoid fatty acids (CPFA) were fed to
rainbow trout. At a level of 223 ppm (from Sterculia foetida oil),
these CPFA in six weeks reduced weight gain by as much as 50 percent
over the control fish on the same diet without CPFA. Compounds
containing the intact cyclopropene...
