Abstract

Phaseolus vulgaris L, known as red bean, is a staple food in Indonesia. The temperature sensitivity of red bean limits the applications despite the high starch content. Therefore, this research aims to analyze the effects of heat-moisture treatment (HMT) on the properties of red bean starch, focusing on the functional and morphological characteristics. The effects of HMT (4, 5, and 6 hours at 110°C) were elevated on fresh and dried red bean starch using Completely Randomized Design. The results show that significant alterations were observed in starch properties due to HMT. Water absorption capacity (WAC) varied with HMT duration and fresh bean starch peaked at 4 hours (198.0 ± 0.1%) before declining at 6 hours (159.5 ± 0.7%). In contrast, dried bean starch showed a decrease from the native capacity of 223.5 ± 5.0% to 176.5 ± 5.0% after 6 hours of HMT. Oil absorption capacity (OAC) also changed markedly and fresh bean starch increased from 68.0 ± 2.8% to 85.5 ± 0.7%. Similarly, dried beans increased from 67.0 ± 1.4% to 83.5 ± 0.7% since the effectiveness of HMT enhanced starch interaction with water and oil molecules. In fresh and dry beans, swelling power decreased and increased with prolonged HMT, reaching a peak at 4 hours (8.57 ± 0.15 g/g). However, solubility index decreased in both types following an increase in HMT duration. The morphology of starch granules transitioned from round or elliptical shapes to more polyhedral and irregular forms, reflecting substantial structural changes. In conclusion, HMT effectively modified the functional properties of red bean starch to offer potential benefits for application in food industry.

Abstract

In Indonesia, the surge in online food Small and Medium Enterprises (SMEs) has underscored the critical need for stringent sanitation and hygiene practices. Utilizing a cross-sectional approach, the research assessed knowledge levels through a questionnaire, complemented by an evaluative tool aligned with guidelines from the Indonesian food and drug regulatory authority. From a sample of 132 SMEs spanning various Indonesian cities and regencies, it was observed that 57.6% had an adequate grasp of sanitation principles. Furthermore, a significant correlation between knowledge and its practical application emerged. Notably, there was a discernible difference in practice scores between participants with limited knowledge compared to those with a deeper understanding, evidenced by a mean difference of 10.62±3.77. This highlights a substantial inconsistency in translating knowledge into practice. Despite a reasonable level of awareness, the practical execution of sanitation and hygiene standards remains uneven among these enterprises. This gap indicates a need for focused interventions to enhance the consistent application of sanitation practices in the Indonesian online food SME industry, ensuring better compliance with established hygiene standards.
