Fermentation is an important processing technology in the modern food industry, which can be used to produce fermented meat products on a large scale. This paper explores the role of fermentation technology in regulating the quality of meat products, and summarizes the current research and application of fermentation agents and fermentation processes in meat processing from three aspects: Screening and construction of fermentation agents, inoculation strategies of fermentation agents, factors affecting fermentation, and process optimization. It also discusses the development trend of fermentation technology in the application of meat products industry in China. Overall, the application of new fermentation technology will break the limitations of the traditional meat industry. In the future, people can adjust the fermentation processes and strategies for the demand characteristics of different fermented meat product qualities to produce nutritious, delicious, safe, and diverse fermented meat products that meet the needs of modern people’s life.

Certain infants and children have relatively high risk of the onset of anaphylaxis when exposed to the foods containing cow milk protein. This pathogenic immunological process is mainly mediated by IgE. Currently, the chief methods eliminating the sensitization of milk protein include heat treatment, high pressure treatment, enzymatic hydrolysis, and glycosylation modification, etc. Based on different mechanisms, each technique has specific advantages, nevertheless, also accompanied with ineluctable shortcomings, such as reducing the nutritional value or generating odd flavors. As a type of secondary metabolites with wide botanical resources, polyphenols exhibit pleiotropic bioactivities involving anti-aging, antibiosis, anti-inflammation and antioxidation. It is well known that polyphenols have strong affinity to proteins via covalent or non-covalent binding, which is so-called 'polyphenol-protein interaction (PPI)'. Accumulating reports showed that phenolic compounds could reduce the immunoreactivity of diverse food allergens through PPI. This review summarizes and discusses the role of PPI on the desensitization of lactoproteins, and proposed some promising conceptions in the light of up-to-date researches, hoping to provide new ideas and theoretical foundations for the development of safe dairy products of low-sensitization.

In order to explore the effect of edible mushroom on the protein flavor adsorption capacity of meat products, beef myofibrillar protein (MP) was treated with Volvariella volvacea extract (VV) and the changes of MP protein intermolecular force and flavor adsorption capacity before and after VV treated were analyzed. The results showed that the extract improved the adsorption capacity of MP to phenylacetaldehyde, 1-octen-3-ol, 2-heptanone, benzaldehyde and D-limonene in different degrees. After VV incorporated, the proportion of the above flavor substances in the MP-extract system decreased by 2.09%, 6.1%, 6.41%, 9.85% and 11.66%, respectively, compared with the untreated group. Urea, guanidine hydrochloride, propylene glycol and β-mercaptoethanol were used to destroy the protein interaction force, and it was found that the hydrophobic force between protein molecules played a dominant role in the process of flavor adsorption, followed by hydrogen bond, covalent bond and ionic bond. VV may improve the adsorption capacity of MP on 2-heptanone, 1-octen-3-ol and D-limonene by enhancing the non-covalent bond between MP molecules, and improve the adsorption capacity of MP on benzaldehyde by enhancing the covalent interaction between MP molecules.

In order to explore the effect of hammering time on the quality of beef gel, beef gel prepared by beating process was used as control group, the color difference, myofibrillar protein oxidation degree, cooking loss rate, fat exudation rate and texture characteristics of beef gel with different beating time were determined, and the mechanism of the impact of beat time on beef gel quality was studied through observing the changes of meat size, protein two level structure and microstructure of beef gel. The results showed that with the extension of beating time, the L* value and W value first decreased and then increased, and the a* value and b* value increased first and then decreased. The oxidation degree of myofibrillar protein increased, total thiol decreased, the carbonyl value and bromphenol blue binding capacity increased, cooking loss rate decreased and then increased with fat exudation, and the hardness and chewiness of gel texture increased gradually. Resilience, cohesion and resilience increased first and then decreased. 30 min was the cut-off point, and the gel quality of 30 min was on the rise, which was more than 30 min. The increasing of gel quality was due to the decreasing of meat particle size and the increasing of protein two level structure beta fold. The degradation of gel quality after 30 min was due to the deepening of protein oxidation and the change of gel microstructure. The results showed that the hammering process could improve the quality of minced meat, but excessive hammering could cause the quality deterioration of minced meat.
