Geosmin (GSM) and 2-methylisoborneol (2-MIB), microbial-derived terpenoid compounds prevalent in aquaculture systems, impair fillet quality disrupt physiological homeostasis aquatic species by inducing oxidative stress lipid peroxidation. Despite their significant impact, effective strategies for eliminating these from fish tissues remain underexplored. In this study, we employed primer-mediated PCR amplification to identify strains that produce 2-MIB GSM evaluated the efficacy of Bacillus licheniformis strain BL23 (BL23) suppressing S. thermocarboxydus (ST), a key contributor synthesis. Experimental were allocated three groups (n = 30 per group): Group C (control, standard feed), T1 (BL23-supplemented T2 (BL23 + ST coculture). Probiotic concentrations tanks maintained at 106 CFU/mL under controlled conditions (30 °C). Tissue aqueous samples collected intervals analysis texture, growth performance, concentrations, with measurements triplicate. Subsequently, B. (BL23), which exhibits inhibitory effects against (ST) growth, was cultured introduced into both specimens systems. The outcomes inoculation cultivation experiments demonstrated emergence an inhibition zone surrounding actinomycetes inoculated BL23. results liquid coculture assays revealed reduction concentration 48 h 101 72 post-coculture initial period. An tissue confirmed exhibited effect on ST, leading substantial decrease content (p < 0.05). However, no statistically improvements observed performance (weight gain, feed conversion rate) or meat texture parameters (hardness, elasticity).

As an effective risk management mechanism, agricultural insurance can reduce the of uncertainty in production and guarantee food security. Based on Chinese provincial panel data from 2003 to 2020, this study uses Entropy Method measure security systematically examines impact climate change as well its mechanisms. The present found that change, especially extreme temperatures, has a significant negative production. promotion effect increases with increased investments technology, education, other factors. Furthermore, our findings suggest presence geographical variations contribution ensuring security, greater coverage major food-producing regions. Additionally, maize yields are better protected by than wheat rice yields.

Processing Technology and Quality Change during Storage of Fish Sausages with Textured Soy Protein

Foods, Journal Year: 2022, Volume and Issue: 11(22), P. 3546 - 3546

Published: Nov. 8, 2022

The addition of textured soy protein (TSP) to surimi products extends the supply fish and improves nutritional sensory properties, which has attracted considerable research interest. In this study, a single-factor experiment orthogonal were used determine optimal process conditions assess quality indicators sausages during frozen storage. results indicated that as follows: 15% TSP, 8% potato starch, 5% lard oil, resulting in gel strength 1894.32 g·cm. During storage formulation-optimized for 180 days, water-holding capacity, whiteness, texture all decreased, whereas cooking loss, thawing thiobarbituric acid reactive substances value, total volatile base nitrogen value increased. Consequently, TSP is beneficial improve score sausages. with added was acceptable after at −18 °C, 120 days.

Differences in nutrient and undesirable substance concentrations in Maurolicus muelleri across the Bay of Biscay, Norwegian fjords, and the North Sea

Frontiers in Marine Science, Journal Year: 2023, Volume and Issue: 10

Published: July 20, 2023

Introduction We are having pressing issues of global food insecurity and malnutrition. Mesopelagic communities in the North Atlantic have been estimated to high biomasses organisms. Some these low-trophic organisms known be nutrient-dense may thus contribute security nutrition. Here, we aim understand variation nutrient undesirable substance concentrations a common mesopelagic species, Maurolicus muelleri Ocean. Methods sampled M. from Bay Biscay (BB), Norwegian fjords (NF), Sea (NS). The micro- macronutrients, metals, persistent organic pollutants (POPs) were measured composite whole fish samples. Results found no difference across sampling areas selected micronutrients except that NF NS samples had higher vitamin A1 than BB fat, fatty acids, POPs but lower cadmium samples; differences fat acids only marginal NF-BB pair. arsenic samples, erucic acid mercury Comparing values against existing EU regulation for nutrients substances human consumption, cause safety concerns due their concentrations, while all qualified as good sources iron, selenium, A1, ω-3 acids. Discussion This study confirms Ocean play an important role However, potential variations related seasonality, body size, maturity level shall taken into consideration prior exploiting such marine resource. Further understanding trophic ecology, life cycles, productivity is essential investigate drivers behind observed concentrations.
