Promoting the ESG concept is of great significance for the realization of the 'Carbon Peaking and Carbon Neutrality' Goals and ESG has gradually become a comprehensive system for evaluating sustainable development. Based on the 2015 ESG ratings of SynTao Green Finance as a quasi-natural experiment and based on the panel data of China's A-share listed companies from 2010 to 2020, this study deeply explores the impact of ESG ratings on the continuous innovation ability of enterprises by constructing a multi-temporal double-difference model and a triple-difference model. The results show that ESG ratings can significantly enhance firms' continuous innovation ability, a conclusion supported by a series of robustness tests. The positive impact of ESG ratings is more prominent for firms with low market attention, state-owned enterprises, and firms with high digital transformation. The impact mechanism suggests that ESG ratings advance firms' ability to continuously innovate by increasing employment, improving employee income, and enhancing firm value. It is further found that ESG ratings are more effective in enhancing the continuous innovation ability of heavy polluters and capital – and technology-intensive firms than other firms. The findings of the study help to promote the sustainable development of enterprises and realize the synergy between ESG construction and high-quality development. [ABSTRACT FROM AUTHOR]

In this work, we have presented a new method for species origin verification of collagen peptides based on DNA techniques. First, we investigate the changes in DNA during the preparation of collagen peptides including the total amount of collagen peptide DNA and the DNA degradation under different processing conditions. Secondly, we discussed the possibility of using polymerase chain reaction (PCR) for follow-up detection of collagen peptides. The results showed that the total amount of DNA decreased as the treatment intensity increased. The size of the cleaved fragments of DNA are mainly concentrated between 200 and 500 bp. On this basis, the combined PCR results finally determined that trace collagen peptide DNA can be effectively amplified with amplicons of about 300 bp to complete the verification of the species origin of collagen peptide. This study provides a new strategy for determining the authenticity of food labels for bovine collagen peptides., Competing Interests: Declaration of competing interest The authors declare no conflict of interest., (Copyright © 2024 Elsevier Ltd.

This study examined the potential of hyperspectral techniques for the rapid detection of characteristic indicators of yak meat freshness during the oxidation of yak meat. TVB-N values were determined by significance analysis as the characteristic index of yak meat freshness. Reflectance spectral information of yak meat samples (400-1000 nm) was collected by hyperspectral technology. The raw spectral information was processed by 5 methods and then principal component regression (PCR), support vector machine regression (SVR) and partial least squares regression (PLSR) were used to build regression models. The results indicated that the full-wavelength based on PCR, SVR, and PLSR models were shown greater performance in the prediction of TVB-N content. In order to improve the computational efficiency of the model, 9 and 11 characteristic wavelengths were selected from 128 wavelengths by successive projection algorithm (SPA) and competitive adaptive reweighted sampling (CARS), respectively. The CARS-PLSR model exhibited excellent predictive power and model stability., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2022 The Author(s).)
