The market demand of fortified or functional food is increasing nowadays because of health-consciousness of consumers (Charalampopoulos et al., 2002). Beverages have been fortified with micronutrients like calcium, iron, zinc, etc. and vitamins and proteins. Beverages are also fortified with herbal extracts, phytochemicals and dietary fibers (Ahmad & Ahmed, 2019;Gruenwald, 2009). Sattu is a popular food product made from roasted Bengal gram in some eastern parts of India like Uttar Pradesh, Bihar, West Bengal, and Odisha. It is used to make traditional drink called Sattu sharbat, which is digestive and thirst quenching. It is rich in protein, dietary fiber and minerals but low in phytochemicals (Jukanti et al., 2012).Phytochemicals inhibit the activity reactive oxygen species (ROS) and prevent chronic diseases like cardiovascular disease, diabetes, cancer, Alzheimer's etc. (Holst & Williamson, 2008). Hence, the phytochemicals (e. g., flavonoids) must be incorporated into the food, as they possess antioxidant activity (Erlund, 2004). Rutin is a flavonoid belonging to subcategory flavones. It has anticarcinogenic, antispasmodic, antiviral, antitumor properties and inhibits lipid peroxidation (Yang et al., 2008). Rutin was not detected in the UPLC analysis of chickpea varieties (Fratianni et al., 2014). Hence, chickpea products can be fortified with rutin to increase the flavonoid content
