Sacha inchi (Plukenetia volubilis Linneo) is a plant from the Euphorbiaceae family known for its green star-shaped fruit and brown seeds. This plant has high nutritional value and significant antioxidant activity (Nuha and Sriwidodo 2022). This study aims to identify secondary metabolite compounds and determine the total phenolic content of the methanol extract of Plukenetia volubilis Linneo leaves. The samples were extracted using the maceration method, then phytochemical tests and total phenol...

This research aims to formulate and examine the physicochemical characteristics and antioxidant activity of sacha inchi (Plukenetia volubilis L.) as a plant-based milk. Moreover, this research also aims to conduct organoleptic tests on the products. The sacha inchi milk is formulated with five ratios: SI1 (sacha inchi 1:10 parts water), SI2 (sacha inchi 2:10 parts water), SI3 (sacha inchi 3:10 parts water), SI4 (sacha inchi 4:10 parts water), and SI5 (sacha inchi 5:10 parts water). Organoleptic...
