Two hundred and eight commercial blocks of imported frozen minced fish examined for aerobic plate count, fecal coliforms, and coagulase-positive staphylococci were found to be in compliance with the proposed standards of the International Commission on the Microbiological Specifications for Foods. There was no significant correlation between aerobic plate count (35 C) and certain indicator organisms (coliforms, fecal streptococci, and coagulase-positive staphylococci).

In this study, minced turkey meat samples were subjected to electron-beam irradiation with dosages of 0, 1.5, 3, and 5 kGy, and then microbial (mesophilic and psychrotrophic bacteria), physiochemical (pH, water activity [a], thiobarbituric acid reactive substances [TBARS], and peroxide value [PV]), and sensory (color, odor, texture, and overall acceptability) analyses were performed at 0 and 6 months of freezing storage (-18°C). Results showed that by 5 kGy irradiation and freezing treatments, the counts of psychrotrophic and mesophilic bacteria reduced remarkably ( < 0.

Myofibrillar proteins are crucial for gel formation in processed meat products such as sausages and meat patties. Freeze-thaw cycles can alter protein properties, impacting gel stability and product quality. This study aims to investigate the potential of thawed drip and its membrane-separated components as potential antifreeze agents to retard denaturation, oxidation and gel deterioration of myofibrillar proteins during freezing-thawing cycles of pork patties.

This study employs sensory evaluation, headspace gas chromatography-ion mobility spectrometry (HS-GC-IMS), and headspace solid-phase microextraction gas chromatography-mass spectrometry (HS-SPME-GC-MS) techniques to investigate the effect of different pretreatment of fresh silver carp mince (running water rinsing 0, 1, or 2 times) and commercially frozen surimi on the odor characteristics of fish noodles. The free choice profiling (FCP) and check all that apply (CATA) sensory analysis methods were utilized to identify 10 characteristic descriptors, which include "grass, fish fragrance, unpleasant fishy, fatty, roast, ammonia, caramel, warmed-over, earthy, and mushroomy". HS-GC-IMS and HS-SPME-GC-MS detected 80 and 37 volatile compounds (VCs) in fish noodles.

Mouse embryonic fibroblasts (MEFs) are primary fibroblasts purified from mouse embryos at a defined time post-fertilization. MEFs have versatile applications, including use as feeder cell layers or sources of untransformed primary cells for a variety of biological assays. MEFs are most commonly isolated between embryonic day (E)12.
