PurposeAlthough there are many efforts within organisations to improve the financial performance of business processes, the results of studies on the impact of internal factors on the financial performance of business processes in an organisation are inconsistent, even contradictory. Therefore, this paper aims to examine the extent and trends of the impact of factors inside companies on the financial performance of business processes and discover lessons learned to improve the financial performance of business processes.Design/methodology/approachThis analysis was done through a quantitative study of listed companies in Vietnam. Pooled OLS regression, REM, FEM and robust regression were performed on 566 companies.FindingsThe results provide four main findings. First, firm size and operational efficiency strongly correlate with financial performance. Second, financial leverage has a negative, significant connection with financial performance. Third, net working capital has a positive and meaningful relationship with EPS and a negative association with ROE. Fourth, liquidity does not have any significant association with financial performance.Research limitations/implicationsThis study only restricts the internal factors affecting the financial performance of business processes without mentioning the external factors. Furthermore, this study is limited to one emerging country and has not been compared with companies in different countries.Practical implicationsThe findings of this study may help inform users inside and outside the organisation to understand the factors that affect the financial performance of business processes. As a result, information users will focus more on aspects that can improve their financial performance to make informed decisions.Originality/valueThis study has many differences compared to previous studies. First, it focuses on the internal factors affecting the financial performance of business processes in non-financial listed companies in Vietnam, which has an emerging economy. First, it focuses on the internal factors affecting the financial performance of business processes in non-financial listed companies in Vietnam, which has an emerging economy. Second, this study analyses data in companies' financial statements for the ten years from 2012 to 2021, when the Vietnamese economy, in particular, and the world economy experienced many fluctuations due to the impact of the post-financial crisis 2007–2008 and the COVID-19 pandemic. Third, this study provides empirical evidence to support RBV, RDT theories and the trade-off theory of capital structure.

The paper studied on the optimization of extraction condition of total polyphenols and flavonoids from dried coffee cherry pulp (Cascara) by response surface methodology. The effect of extraction conditions such as solvent (water)-to-material ratio (X1); temperature (X2) and time (X3) were studied. The results showed that the best combination of extraction conditions for dried coffee cherry pulp was at 1: 40.77 solid- sovent ration, 71.59oC and 48.39min. At optimal extraction conditions, total polyphenol content achieved 23.816 mgGAE/g and total flavonoid 11.365 mgQE/g of dry basis.Applying the optimization conditions of extraction process to drinking water products from coffee cherry pulps and implementing sensory methods according to the ranking test method to determine the mixing formula. Results obtained syrup ratio 90bx, citric acid content is 0.01%. According to the consumer acceptance test, the final product of this research was rated 4.7 on a scale of 7, the studied product has good organoleptic properties and sterilization standards, ensuring food safety for consumers. Our research results indicated potential of using dried coffee cherry pulp (Cascara) as promisisng resources for extracting natural antioxidants.Key words: coffee cherry pulp, Cascara, polyphenol, flavonoid…

Kappaphycus alvarezii is a type of seaweed containing numerous carbohydrate with biological activities, especially fucoidan. About chemical aspect, fucoidan is fucose polysaccharides (FCSPs) with diverse biological activities including antioxidant, anticoagulant, anti-inflammatory, antiviral, antitumor... Fucoidan is found not only in brown algae but also in K. alvarezii alga from the central coast of Vietnam. In this study, fucoidan purification, fucoidan structure and biological activities of K. alvarezii alga (collected at Dam Mon area, Khanh Hoa province) were investigated. The yield recovery of two-stage precipitation by ethanol 99% was 84.4%. The protocol of fucoidan purification by ion-exchange chromatography was applied with tris-HCl buffer, elution solvent NaCl 1M; The yield was 60.99%. The structure of fucoidan from K. alvarezii was determined by 1H-NMN spectrum with the specific characteristic properties of fucoidan. The antioxidant activity of the purified fucoidan via IC50 was 303.51±0.12 μg/mL (DPPH assay), 299.97±3.12 μg/mL (ABTS essay). The purified fucoidan was shown better ability in cases of anti-coagulant, antibacterial activities than that of the crude extract. The anti-coagulation time of the purified fucoidan was 22.52 minutes. The minimum inhibitory concentrations (MICs) of the antibacterial activity (Bacillus cereus, Escherichia coli) were 400μg/mL. MICs was 500 μg/mL (Aspergillus flavus) and 600 μg/mL (Aspergillus niger).
