RESUMO
BACKGROUND: Noodle products are popular throughout the world, and they can be prepared from cereal like wheat, maize, and rice. Nowadays, healthy and nutritious product requirement has been increasing. Thus, research on the nutrition-rich but neglected crop is becoming visible nowadays to ensure global food security and to satisfy the nutritional need. Research indicated that moringa tree leaf powder has good nutritional value, but it is not yet customized and properly consumed. METHOD: The study is aimed at developing noodles from wheat flour and moringa leaf powder and evaluating proximate composition, antinutritional content (phytate and tannin), microbial load (total plate count and yeast and mold count), and sensory acceptability. The experiment contains four treatments and one control. The data from proximate composition, antinutritional content, microbial load, and sensory acceptability were subjected to SAS version 9 software. A complete randomized design was used to analyze the proximate composition, antinutritional content, and microbial load data, and a randomized complete block design was used to analyze the acceptability test. RESULT: The study revealed that in the noodles formulated from 80% durum wheat flour and 20% of moringa leaf powder, the ash, protein, fat, fiber, gross energy, phytate, and tannin content were increased by 39.39%, 10.86%, 153%, 42.2%, 3.43%, 39.83%, and 329.78%, respectively, as compared with noodles made from 100% durum wheat flour. However, moisture, total bacteria count, and yeast and mold count were decreased by 28.71%, 45.52%, and 55.93%, respectively. Similarly, the study also revealed that the acceptability test of noodles was decreased as moringa leaf powder concentration is increased. CONCLUSION: In conclusion, besides the good nutritional profile and antimicrobial capacity, moringa has antinutritional content and influences the sensory acceptability of products. Therefore, limiting the moringa leaf powder concentration is needed during the development of products using moringa leaf powder.
RESUMO
BACKGROUND: Breads are made throughout the world. Bread can be prepared from cereal like wheat, maize, and rice. Nowadays, gluten intolerance, requirement of healthy, and nutritious products have increased and interests towards underutilized crops have also been increasing with the aim of improving global food security and to ease an adverse effect of climate changes. Amaranth is one of nutritionally balanced and naturally grown underutilized crops, but it is mainly considered weed in Africa including Ethiopia. METHOD: The aim of the study is to develop bread from wheat and Amaranthus and to evaluate proximate composition, antinutritional, microbial, and sensory acceptability of bread. The experiment contained 100% wheat as control and four blending proportions (90% wheat and 10% amaranth, 80% wheat and 20% amaranth, 70% wheat and 30% amaranth, and 60% wheat and 40% amaranth). A complete randomized design is used for proximate composition, antinutritional, and microbial data analysis whereas a randomized complete block design with three replications was applied for sensory acceptability. SAS for windows version 9 was used for data analysis. RESULT: The study revealed that moisture, protein, fat, fiber, and antinutritional content were increased as Amaranthus concentration is increased from 10% to 40%. However, carbohydrate, microbial load, and sensory acceptability were decreased. But the gross energy is constant. CONCLUSION: From the study, it can be concluded that beside the good nutritional profile of Amaranthus, it has antinutritional content which needs to limit the concentration of Amaranthus in blending with other grains during product development.
