Abstract

Black glutinous rice (Oryza sativa var. glutinosa) tape fermented with various yeast, mold, and bacteria is often rich in phenolics compounds and can contribute positively to health through its antioxidants activity. Despite the potential, these compounds have limited bioavailability value due to their structure, degree of glycosylation or polymerization, and interactions with other components. Therefore, this study aims to determine the effect of fermentation on bioavailability and bioaccessibility of phenolics compounds in black glutinous rice tape. During the procedures, cooked black glutinous rice was inoculated with ragi tape for 72 hours. Sampling was then performed every 24 hours to analyze bioaccessibility of phenolics compounds, flavonoids, and antioxidants activity. Subsequently, absorption was carried out using an everted gut sac model. The results showed that phenolics compounds were released from the food matrix during gastric and small intestine digestion. Fermentation was shown to increase the content of accessible phenolics compounds from 19.89% to 27.31%, flavonoids from 68.88% to 81.72%, and antioxidants activity from 13.56% to 22.89%. During fermentation, the highest increments were obtained after 72 hours, with 27.31% for total phenolics compounds, 81.72% for flavonoid compounds, and 22.89% for antioxidants activity. The products obtained after 72 hours of fermentation exhibited significantly highest absorption, but no significant differences were observed between the duodenum and ileum segments. The absorption of these compounds in the jejunum from the extract was significantly higher in fermented samples. Therefore, fermentation significantly enhanced bioavailability of phenolics compounds in black glutinous rice tape.

Abstract

Several types of local Indonesian legume have the potential to be developed into plant-based milk yogurt, including pigeon peas, soybeans, and mungbeans. However, the protein contained in legume milk is characterized by low digestibility and bioavailability, underscoring the need to combine several types of legume and proper bioprocessing. Fermentation of legume milk by L. bulgaricus and S. thermophilus has been shown to improve the sensory and nutritional value of yogurt. Therefore, this study aims to analyze the nutritional value, protein digestibility, and total LAB of yogurt from a single type of legume (pigeon peas) and a combination (pigeon peas, mungbeans, and soybeans). The experiment used a completely randomized design with one factor, namely the composition of each legume, consisting of 4 treatments and 5 repetitions. The treatment of the study consisted of P1 (pigeon peas), P2 (pigeon peas + mungbeans 1:1), P3 (pigeon peas + soybeans 1:1), and P4 (pigeon peas + mungbeans + soybeans 1:1:1). The results showed that composition of legume type had a significant effect on proximate levels, dissolved protein, protein digestibility, lactic acid, and pH, but not the total lactic acid bacteria LAB of yogurt. The protein content, digestibility, and the soluble protein of legume-yogurt increased by approximately 1.21-1.86%, 0.36-0.44%, and 0.81-1.30%, respectively. In conclusion, yogurt from a single type of legume produced lower proximate levels, dissolved protein, protein digestibility, lactic acid, and low pH, while the combination of two or three types showed higher values for these parameters. Among the combinations, pigeon peas yogurt + soy produced higher proximate, dissolved protein, protein digestibility, lactic acid, as well as lower pH compared to pigeon peas yogurt + mungbeans.
