PERUBAHAN ALERGENISITAS PROTEIN KACANG KEDELAI DAN KACANG BOGOR AKIBAT PENGOLAHAN DENGAN PANAS

ISOLASI PROTEIN KACANG MERAH DAN KACANG HIJAU MENGGUNAKAN METODE ASAM BASA DIKOMBINASIKAN DENGAN PROSES ENZIMATIS

Red beans (Phaseolus vulgaris L.) and greens beans (Phaseolus raditus L.) proteins contain high amount of essential amino acids lysine and leucine. The study aimed to determine the optimum conditions for protein isolation process from red beans and green beans flour to produce the highest protein content. Additionally, an enzymatic hydrolysis was aimed to produce isolates or protein concentrates of red beans and green beans with good digestibility. The research method used was the Response Surface Methodology (RSM) Box-Behnken Design with Design Expert 10. The variables used in this process were extraction temperature (30-50°C), extraction pH (8.50-9.50), and time extraction (30-60 minutes). The results showed that the optimum conditions for the extraction of red beans protein were extraction pH of 8.60, temperature of 30°C, and time of 30.1 minutes, with the resulting protein content of 86.88±1.38% with and a validity value of 0.91. Meanwhile, the optimum conditions for the green beans protein extraction process were extraction pH of 8.83, extraction temperature of 30°C, extraction time of 30 minutes which yielded protein content of 88.27±1.08% and a validity value of 0.97. Enzymatic hydrolysis using of 3% (w/w) bromelain enzyme on red bean and mung bean protein concentrate powder was able to increase protein digestibility by 15.61 and 14.51%, respectively.

Analysis of Household Food Security Based on the Proportion of Food Expenditures and Energy Consumption in Flood-prone Areas in Wajo District

BACKGROUND: Floods that inundate almost all areas in Wajo district caused difficulties for people in this district to access their daily needs, especially for foods as the distribution was inhibited. This situation was exacerbated as the food price increased leading to a greater risk of food insecurity of the household in this area. AIM: The current study aimed to determine food security in flood-prone areas in Wajo District. METHODS: This study was a cross-sectional conducted in the three subdistricts in Wajo Regency. The study was conducted from March to May the year 2018. A total of 304 study participants were involved in this study. The data have been collected using the developed questionnaire and observation sheet. All data analyses were performed using SPSS. RESULTS: The result of the study shows that 139 households (46%) included in this study were in the condition of lack of food and 165 households (54%) were food insecure. Households with food-resistant and food vulnerable status were not found in the study area. CONCLUSION: Therefore, households with food insecurity should manage their income by considering providing nutritious foods based on their income situation.
