Physicochemical property of oil palm leaves and utilization of cellulose microfiber as probiotic encapsulant

Abstract. Pato U, Ayu DF, Riftyan E, Restuhadi F, Pawenang WT, Firdaus R, Rahma A, Surono IS, Jaswir I. 2021. Physicochemical property of oil palm leaves and utilization cellulose microfiber as probiotic encapsulant. Biodiversitas 22: 2937-2944. The vast land (Elaeis guineensis) in Indonesia has a huge potential for solid waste, which can be used various human needs. physiochemical analysis performed was proximate fiber content, FTIR X-ray diffraction analysis, an vitro test on viability resistance to acid bile during storage at room refrigerated temperatures. main content carbohydrates, especially followed by ash, protein, fat. Fiber from is mainly composed lignin hemicellulose. showed that the crystal index 10.1%. enormous absorption value, stretching vibrations -OH group ranging 2919.17 2914.82 cm-1. Cellulose maintained L. fermentum InaCC B 1295 up 28 d survival strain B1295 low pH presence very high, characterized decrease number cells less than 0.5 log CFU/mL 35 Therefore, encapsulant probiotics.
