| Popis: | This study evaluates proximate, antinutrient, and antioxidant activities of raw and processed quinoa flour (RQF and PQF). Product development and sensory evaluation were also addressed to provide prospects for human consumption. Methods: Quinoa was processed by two methods - soaking and roasting. Some nutrients like moisture, ash, protein, carbohydrate, crude fibre, fat, iron, calcium, vitamin C, phytic acid, saponins, total phenol, and 2,2-diphenylpicrylhydrazyl (DPPH) were analyzed. The recipes were made and conduct acceptability evaluation by a 9-point hedonic scale. The mean, standard deviation, and One-Way Analysis of Variance (proximate, antinutrient, antioxidant) were utilized as the statistical approach for the analysis of data. Results: The study revealed that some nutrient composition of RQF was found to be impressive with moisture (11%), ash (2.1%), protein (16.6%), crude fibre (2%), iron (11.6%), and calcium (76.1%) as compared to PQF; however, carbohydrate (69.9%), fat (9.6%), and vitamin C (9.1%) was increased in PQF, and phytic acid and saponins were decreased in all the PQF. DPPH’ free antioxidant potential was observed that RQF lowered free radical scavenging activity. In all PQF, the total phenol content was both raised and reduced. Also, proximate and antioxidant activity showed significant differences (P0.05). The two recipes were prepared as upma (soaked for 48 h), and chakli (roasted at 145 °C). Sample B of upma (50% semolina with 50% soaked quinoa flour) and sample A of chakli (75% refined flour with 25% roasted quinoa flour) were more acceptable. Conclusion: This study concluded that the use of domestic processing of quinoa seeds decreases some nutrient value compared with RQF and also infers the dietary importance of quinoa. |
