EJECTION CHARACTERISTICS, TENSILE STRENGTH AND PROTEIN CONTENT OF COMPACTED WINGED BEAN (KACANG BOTOL) SEED CONTAINING LACTOSE

Abstract

Currently, there is a lack of information in the literature regarding the compaction of winged bean seed into tablet form. Therefore, this research study into the compaction of winged bean seed powder containing lactose monohydrate as an excipient into tablet form. Winged bean, an underutilized legume, holds a great potential for innovative health solutions due to its high protein content. The research was conducted to develop a chewable tablet containing different compositions binary mixture consisting of winged bean seed powder and lactose monohydrate powder using uniaxial compaction method. This work focus on determining the winged bean seed chewable tablet ejection characteristics during the compaction process, tablet tensile strength, and its protein content. The tablet ejection characteristics were determined from the force-displacement data obtained during the ejection stage of the compaction process. The tablet tensile strength was measured using the indirect tensile strength test. Meanwhile the protein content was determined using the Kjedahl method.Based on the results obtained, increasing the composition of lactose powder improves the tensile strength of the tablet by increasing the tensile strength up to 0.27 ± 0.05 MPa. Moreover, a higher amount of lactose powder results in higher maximum ejection force during tableting up to 1.06x10^-5 ± 6x10^-6 kJ. The maximum protein content was obtained for pure winged bean seed tablet at 29.55 g/100g. The results obtained are useful for developing winged bean seed chewable tablets.
