Dynamic changes in the gel properties, microbial community, and volatile flavor profile of Spanish mackerel () sausages inoculated with CY1-2.

Spanish mackerel is an important economic fish species in China, but corruption undermines its overall economic value. Fermentation serves as a crucial technique for preserving perishable fish in developing countries. This study aimed to examine the dynamic changes in the gel properties, physicochemical properties, microbial diversity, and volatile flavor compounds (VFCs) of Spanish mackerel sausages inoculated with CY1-2 during fermentation.

Fermented Vegetables: Health Benefits, Defects, and Current Technological Solutions.

This review summarizes current studies on fermented vegetables, analyzing the changes in nutritional components during pickling, the health benefits of fermented vegetables, and their safety concerns. Additionally, the review provides an overview of the applications of emergent non-thermal technologies for addressing these safety concerns during the production and processing of fermented vegetables. It was found that vitamin C would commonly be lost, the soluble protein would degrade into free amino acids, new nutrient compositions would be produced, and the flavor correlated with the chemical changes.

Effect of partial substitution of wheat flour with kiwi starch on dough rheology, microstructure, the quality attributes and shelf life of Chinese steamed bread.

Chinese steamed bread (CSB), a conventional high-GI staple food, with a short shelf life and a single flavor. In this work, 10-20 % kiwi starch (KS) was used to substitute wheat flour for the production of CSB and the effects of different substitution ratios on the quality and shelf life of mixed flour, dough, and CSB were explored. The results showed that the substitution of KS could improve the water binding capacity of mixed flour and lead to easier pasting in the system, lower the cooking power consumption, increase and improve the viscoelasticity and gas holding capacity of the dough, and make the microstructure more compact and uniform.

Synergistic effect of ultrahigh pressure and allicin on gel properties, flavor characteristics, and myosin structure of the obturator muscle of the scallop (Patinopecten yessoensis).

The synergistic effects of the combination of ultrahigh pressure (UHP) with allicin on the gel properties, flavor characteristics, and myosin structure of scallops were investigated. The results indicated that chewiness reached maximum, uniform, and dense microstructures at B-300 MPa, and scallops with favorable gel properties. In addition, the electronic nose and tongue could clearly distinguish the olfactory and gustatory properties of scallops, and the interaction of UHP and allicin increased the variety of volatile compounds in scallops, which mainly included 1-hydroxy-2-propanone, 1-hexenal, 2-butanone-D, and 1-octen-3-ol.

Optimization of strains for fermentation of kiwifruit juice and effects of mono- and mixed culture fermentation on its sensory and aroma profiles.

In this study, a quality evaluation model of fermented kiwifruit juice (KJ) based on strain growth characteristics, sensory quality and functional characteristics was established by PCA, and the effects of mono- and mixed culture fermentation on the sensory and aroma profiles of KJ were comparatively studied. Experiments determined that (LB) was the optimal strain for monoculture fermentation, and (LP2):LB = 1:2 was the optimum ratio for mixed fermentation. The results showed that lactic acid bacteria (LAB) fermentation significantly reduced the pH, soluble solid content and lightness, and improved its functional characteristics and viscosity.

Complete Genome Analysis Reveals the Quorum Sensing-Related Spoilage Potential of PF08, a Specific Spoilage Organism of Turbot ().

is a common specific spoilage organism (SSO) of aquatic products. The spoilage ability of SSO can be regulated by the quorum sensing (QS) system. However, the QS system in and their relationship with the spoilage potential have not been systematically analyzed.

Modification in structural, physicochemical, functional, and in vitro digestive properties of kiwi starch by high-power ultrasound treatment.

Kiwi starch (KS) is a fruit-derived starch; in order to improve its processing performance and increase its added value, it is necessary to modify KS to enhance the positive attributes and to enlarge its application. In this study, KS was modified by high-power ultrasound treatment (HUT) to reveal the relationship between the structure and function of KS with different treatment powers (0, 200, 400, and 600 W) and different treatment times (0, 10, 20, and 30 min). The results showed that HUT destroyed the granular morphology of KS, formed holes and cracks on the surface, and reduced the particle size and the short-range molecular order of KS.

Perspectives of small molecule inhibitors of activin receptor‑like kinase in anti‑tumor treatment and stem cell differentiation (Review).

Activin receptor‑like kinases (ALKs), members of the type I activin receptor family, belong to the serine/threonine kinase receptors of the transforming growth factor‑β (TGF‑β) superfamily. ALKs mediate the roles of activin/TGF‑β in a wide variety of physiological and pathological processes, ranging from cell differentiation and proliferation to apoptosis. For example, the activities of ALKs are associated with an advanced tumor stage in prostate cancer and the chondrogenic differentiation of mesenchymal stem cells.

Isolation of antioxidative peptide from the protein hydrolysate of Caragana ambigua seeds and its mechanism for retarding lipid auto-oxidation.

Background: Peptides can act as antioxidants in emulsion, although the mechanism involved is poorly understood. Caragana ambigua seed is a potential protein source for which the commercial applications have not been explored yet. In the present study, we aimed to evaluate the bio-economic potential of C.

Activin A regulates activities of peripheral blood natural killer cells of mouse in an autocrine and paracrine manner.

Activin A, a multifunctional cytokine of transforming growth factor-β (TGF-β) superfamily, can be produced by the diverse immune cells. NK cells in peripheral blood are one of the major immune cells applied to cancer therapy in recent years. However, whether activin A can be produced by natural killer (NK) cells and be involved in regulation of peripheral blood NK cells activities of mouse are not well characterized.
