Kokoro, a maize-based snack was made from maize flour and supplemented with Moringa seed flour (MSS) and defatted sesame flour (DSF) flours with the aim of improving its nutritional quality. An experimental design was carried out using optimal mixture model of response surface methodology which yielded 16 formulations in which three blends in terms of the best proximate composition and the control sample (100% maize) were selected. The snacks were analyzed for proximate, mineral, amino acid composition, sensory and antioxidant properties. Proximate analysis results showed significant (p<0.05) increase in protein (9.25–24.23%), fat (15.07–35.25%), ash (2.25–4.25%) content, and energy value (508.43–607.71 KJ/ g), while crude fiber (7.58–5.80%), moisture (4.58-3.64%) and carbohydrate (61.27–26.83%) content decreased with inclusion of MSF and DSF. Potassium (4.02-5.03mg/100 g) was the predominant mineral, followed by calcium (3.31-5.41mg/100 g) and potassium (1.67-3.75mg/100 g). Glut...
Quality Attributes of Snack made from Maize Substituted with Groundnut
Ceylon Journal of Science, 2020
Snacks made of maize are popular in Nigeria, but deficient in two essential amino acids (Tryptophan and lysine) and niacin. In this study, the quality attributes of maize snacks fortified with groundnut paste (10-40%) of boiled and roasted groundnut were studied. The functional properties of the flour blends were analysed. Snacks were analysed for proximate, colour and sensory attributes. Results showed significant differences (p<0.05) in the proximate composition of the blends. Protein content increased with the substitution of groundnut paste (13.15 to 24.31%), which could be responsible for the improved nutrition recorded in the snack samples produced. The ash, fat, and fibre contents also increased accordingly, with values ranging from 0.97-3.02%, 14.63-16.69%, and 1.50-1.67% respectively, but the carbohydrate content decreased with increasing substitution of the maize flour with the groundnut paste. The water and oil absorption, as well as the swelling capacities significantly decreased when increased levels of groundnut paste were used. Sensory evaluation revealed that the snacks made with 10 and 20% roasted groundnut paste substitution were better accepted and therefore can be recommended for large scale production.
Formulation, Development and Quality Assessment of Nutri-Rich Snack Food (Sev)
Asian Journal of Dairy and Food Research, 2019
The study was carried out in the Department of Food Science and Technology, JNKVV, Jabalpur, MP, India, with the objectives to develop the Nutri-rich snack food (Sev) based on Minor Millet, (Kodo) and to evaluate the sensory and nutritional quality of the product. Chickpea and soybean is an important legume with a rich source of protein and dietary fiber. Millets are nutritionally superior to other cereals. Minor millet Kodo is a nutritious millet with the highest dietary fiber (14.3%) makes it ideal food. On the basis of present findings it was concluded that S 3 (60:20:20 ratio of chickpea, Kodo and soy flour) was highest acceptable with respect to all sensory attributes like colour and appearance, taste, flavor, texture and overall acceptability and physical characteristics of final product with the nutritional value of carbohydrates, protein, ash, fat and crude fibre with the percentage of 52.16, 25.06, 2.80, 8.80 and 5.0 respectively. Functional properties are directly related to the quality of the final product. In the present investigation, the high content of oil in the blends having a high ratio of soy flour may develop off-flavor. Thus it could not be used beyond 20 percent.
Chemical, Physical, Nutritional and Sensory Properties of High Fiber Healthy Corn Snacks
High fiber low calorie healthy snacks were prepared using yellow corn grits incorporated with different fiber sources (soybean, carrot and pea hulls). The fibers sources were added to the yellow corn grits at 10-40% fibers to 90-60% yellow corn grits. The effects of added fibers on chemical (moisture, protein, fat, ash, crude fiber, total dietary fiber and carbohydrate), physical (expansion index, bulk density, water absorption, water solubility indexes, color attributes and breaking strength), nutritional (protein digestibility, carbohydrate digestibility and calorific value) and sensory (appearance, aroma, color, taste and texture) characteristics of extruded products were evaluated. Adding the soybean fiber, to the yellow corn grits, enhanced the sensory characteristics of the final extruded products displayed a great ability to produce an excellent extrudates compared with other fiber sources.

Malnutrition is one of the century's most pressing challenges. If malnutrition is not addressed early, people may suffer from non-communicable diseases. A proper, nutritious diet is necessary to overcome diseases like malnutrition. The technology like extrusion can develop rich fortified food products by retaining high nutrition content. In this study, extrusion technology was used to develop protein and carbohydrate snacks with proper nutrition based on the physical properties of commodities by combining different ratios of corn grits, apple pomace, and mung beans. The objectives of the study focused on the development of a food product based on engineering aspects and the quality cum nutritional evaluation of the finished product that can be used as a diet to combat malnutrition. Physical properties like color, rehydration ratio, porosity, bulk density, water solubility index, texture, sensory evaluation, hardness, and crispiness were studied in detail. The energy content of protein and carbohydrates was measured for nutritional assessment using Food Data Central as a standard, provided by the United States of America Department of Agriculture. Results reveal significant variations among treatments, with the addition of apple pomace impacting bulk density, water solubility index, and color attributes. Mung bean supplementation demonstrates a direct correlation with increased hardness and influences porosity. The rehydration ratio is positively affected by apple pomace. Sensory evaluation underscores the substantial impact on color, texture, crispiness, taste, and overall acceptability, providing valuable insights for snack formulation.

Kokoro is a popular maize-based snack in Nigeria, which is consumed by adults and children but characterized by low protein content. The snacks were produced from blends of maize flour supplemented with protein hydrolysate from pigeon pea at 100:0 (control), 95:5, 90:10, 85:15, and 80:20. Flour blends were evaluated for functional and pasting properties, while snacks were analyzed for proximate composition and sensory qualities. Proximate analysis results showed significant (p < 0.05) increase in protein (9.64-11.12%), fat (13.40-20.17%), ash (1.83-2.38%) content, and energy value (431.84-468.97 kcal/100 g), while fiber (1.19-0.96%) and carbohydrate (68.17-60.74%) content decreased with inclusion of protein hydrolysate. No significant difference (p < 0.05) occurred in the sensory qualities of products from 100% maize and 80:20 flour blend. Hence, acceptable Kokoro snacks from an 80:20 (maize: protein hydrolysate) blend have been formulated, which could enhance the nutritional wellness of the target consumers.
The effect of treated Distillers' spent grain (DSG) supplementation on the nutritional and sensory properties of kokoro, a maize-based snack, was investigated. Treated DSG was used to replace 5%, 10%, 15%, 20%, 25%, 30% and 35% of maize flour. Mean water absorption capacity of DSG was 291%, swelling capacity 2.27 bulk density was 58%, oil absorption capacity 216, protein content of 27% and a total dietary fibre content 24.2%. The swelling, water and oil absorption capacities of the flour blends increased while bulk density decreased significantly. The ash, fat, protein, insoluble and total dietary fibre and total nonessential and essential amino acids contents of the flour blends increased with DSG inclusion. Processing the flour blends to kokoro slightly increased the ash, fat and protein contents, while the total nonessential and essential amino acids, total sugar and total dietary fibre decreased. The addition of DSG increased the lysine and tryptophan contents of kokoro. Although the sensory evaluation results indicate that kokoro with 5%, 10% and 15% DSG were well accepted and compared favourably with those made from whole maize for overall acceptability, it was observed that generally, there is a consumer dislike of the new product as the amount of DSG added increased.
Physical properties and consumer acceptance of maize-baobab snacks
Heliyon, 2019
In this study, an instant maize meal (IMM) was composited with baobab fruit powder (BFP) and commercial starch (CS) which was used as a binding agent. The formulation for the snack was optimised with response surface methodology using design expert software. Thirteen experimental runs were generated by the software and prepared into composite snacks. The snacks were baked using a pilot scale baking oven and microwave oven. The maize-baobab snacks were analysed for colour and texture using different probes (compression force, guillotine, v-shaped and puncture probe). The optimised snacks were evaluated for consumer acceptability and textural properties (instrumental). The results showed an increase in the hardness, fracturability, crunchiness and thickness as the instant maize meal and baobab concentrations increased in the formulation. The colour of the snacks was significantly affected as the concentration of baobab fruit powder and commercial starch increased in the formulation. However, significant correlations existed between sensory attributes and textural parameters in both baking methods except for puncture and aroma of oven-baked snacks.

Most snacks are prepared from basically cereal flours which are nutritionally inadequate. There is the need to complement the nutrient content of these snacks by varying the food sources. Chin-chin snacks were produced from composite flours of Maize, soybean and OFSP with the following formation; sample A (50%: 25%: 25%), B (25%: 25%: 50%), C (25%: 50%: 25%), D (0%: 50%: 50%) and E (50%: 50%: 0%). Wheat flour (100%) served as the control F. The flour bends were analysed for functional properties while the chin-chin snacks were analysed for their nutrient and sensory qualities. The result of functional properties of the flours showed that bulk density of wheat flour (F) was the highest (0.746 g/ml). OFSP flour enhanced the water absorption capacity of the flour blends. Flour blends with soybean recorded higher values in foam capacity (11.20 - 22.55%). In proximate composition, the moisture was low (3.80 – 4.80%) in the chin-chin. Higher fibre content (2.60 - 4.20%) was obtained in sa...
