The aim of the present work was to evaluate the effect of reducing nitrite content on the physicochemical, microbiological, proteolytic, and volatile properties of Cantonese sausages during fermentation and storage. The Cantonese sausages were divided into six groups based on the amount of nitrite added (0, 30, 60, 90, 120, and 150 mg/kg). Results showed that among the physicochemical parameters, moisture, weight loss, a* value, thiobarbituric acid reactive substance value, and nitrite residue levels were significantly affected (p < 0.05) along with nitrite reduction. In addition, the total viable counts and Gram-positive cocci increased with the reduction of nitrite, while lactic acid bacteria decreased. The band densities of actin (48 kDa) increased with the reduction of nitrite, while no major change in sarcoplasmic protein bands was observed. The results of volatile compounds suggested that the reduction of nitrite mainly affected compounds originating from carbohydrate fermentation, esterase activity, and lipid oxidation.

Contemporarily, depression has become a common psychiatric disorder that influences people's life quality and mental state. This study presents a systematic review analysis of depression based on a hierarchical structure approach. This research provides a rich theoretical foundation for understanding the hot spots, evolutionary trends, and future related research directions and offers further guidance for practice. This investigation contributes to knowledge by combining robust methodological software for analysis, including Citespace, Ucinet, and Pajek. This paper employed the bibliometric methodology to analyze 5,000 research articles concerning depression. This current research also employed the BibExcel software to bibliometrically measure the keywords of the selected articles and further conducted a co-word matrix analysis. Additionally, Pajek software was used to conduct a co-word network analysis to obtain a co-word network diagram of depression. Further, Ucinet software was utilized to calculate K-core values, degree centrality, and mediated centrality to better present the research hotspots, sort out the current status and reveal the research characteristics in the field of depression with valuable information and support for subsequent research. This research indicates that major depressive disorder, anxiety, and mental health had a high occurrence among adolescents and the aged. This present study provides policy recommendations for the government, non-governmental organizations and other philanthropic agencies to help furnish resources for treating and controlling depression orders.
