ASEAN Journal on Science and Technology for Development

The COVID-19 pandemic has significantly impacted organizations, underscoring the critical role of financial factors in determining performance. Maintaining a healthy financial stance during crises necessitates effective risk management, prompting the exploration of a Risk Management Committee (RMC) as a focal point for addressing risk issues and managing internal controls. A study spanning 2017 to 2021 assessed 11 listed companies in the Telecommunication and Media Sector, revealing that a combined RMC did not enhance financial performance, indicating its ineffectiveness during the crisis. The study advocates for a separate risk management committee due to the audit committee’s limitations in performing both functions. …

The composition of fats and oils significantly impacts the flavour, nutrition, and appearance of food. Excessive consumption of saturated fatty acids, primarily found in animal fats, raises the risk of coronary heart disease. To address this, plant-based fats are used as substitutes, with microalgae offering unique nutritional benefits as a fat source. This study evaluates the performance of structured plant-based fats, incorporating microalgae (Aurantiochytrium sp. SW1), as a fat substitute in chicken patties. Four formulations were tested: 0% (control), 5%, 7%, and 10% structured microalgae-based fat. Colour, texture, water-holding capacity, cooking loss, and microstructure in both raw and cooked samples …

ASEAN Journal on Science and Technology for Development

Sugar content is a superior quality indicator for the post-harvesting and ripening status of climacteric fruits. Total soluble solids (TSS) represented by °Brix index is a measure of the sugar content. The conventional way to measure TSS is by invasive (IN) technique using manual or digital refractometers. While non-invasive (NIN) infrared refractometer devices have been developed in recent years for various agricultural and food science applications, its accuracy to measure fruit TSS directly is not straightforward, as the device is only dedicated to uses for a specific fruit. This study aims to investigate the suitability of the use of a …
