     Abstract Abstract. Sacha inchi meal (SIM), Plukenetia volubilis, is a by-product obtained from oil pressing process. It is rich in protein and omega-3 fatty acid. However, it contains antinutritional factors (ANFs) which cause low digestibility and growth of fish. This research was aimed to evaluate the nutritional quality, antinutritional factors and nutrient digestibility of SIM by methanol-soaked treatment (soakedSIM), compared to SIM and soybean meal (SBM), as protein ingredients in the diet of juvenile Nile tilapia, Oreochromis niloticus. SIM was soaked in 80% methanol (1:10 w/v) for 48 h before drying. Crude protein of soaked-SIM (63.3%) was higher than those of SIM (56.5%) and SBM (45.5%). Crude fiber of soaked-SIM and SIM was lower than that of SBM. Soaked-SIM and SIM were rich in linoleic acid, linolenic acid, the ratio ω6/ω 3 was 0.92 and 1.01, respectively. The arginine and leucine content of soaked-SIM and SIM were higher than SBM while soaked-SIM had the lowest amounts of tannins, phenolic, saponins and trypsin inhibitor. The in vitro protein digestibility was conducted in juvenile Nile tilapia, result showed that soaked-SIM displayed significantly higher protein digestibility than any others (p < 0.05). Apparent digestibility coefficients of dry matter, protein, and lipid of soaked-SIM were significantly greater than of SBM (p < 0.05). Our finding suggested that methanol soaking method could improve the quality of SIM in terms of crude protein content, nutrient digestibility, and reduced amounts of ANFs. Besides, as nutritional value was improved in soaked-SIM, this suggests that soaked-SIM is a sustainable alternative protein source for fish feed.
