The present study was concerned with the preparation of potato flour with various treatments and to formulate the chapatti and biscuit incorporating potato flours were prepared by treating the raw potato slices as blanched, blanched plus potassium meta-bisulphite (KMS) treatment and one as control. Various substitution levels from 15 % to 30 % of potato flour was used in the formulations of chapatti and biscuit in conjunction with wheat flour. Chapatti and biscuit prepared with either blanched or blanched plus KMS treated sample of potato flour had very good physical and baking quality. And chapatti prepared with 20% potato flour and biscuit containing 25 % had the most suitable baking properties among other proportions. The statistical analysis of sensory evaluation data indicated that the baked products prepared with potato flour from blanched plus KMS-treated samples ranked very well and were more acceptable than those made from blanched sample.

The study aimed to demonstrate how irradiation affects the chemical composition and amino acids of Spunta potato flour, and the sensory evaluation of biscuit samples partially composed of irradiated potato flour. The potato flour was irradiated with 50 and 150 Gy. Protein, fat, total dietary fibre, ash, carbohydrates, ascorbic acid, and amino acids were analysed. Sensory evaluation of biscuits was conducted after adding potato flour as a partial replacement for wheat flour at ratios of 5, 10, and 15%. The results showed that potato flour contained ascorbic acid, which was absent in wheat flour. Potato flour had less total protein and carbohydrate and more ash and fibres than wheat flour. Total essential amino acids appeared at the highest percentage, particularly lysine at 8.29 ± 0.02, compared with non-essential amino acids in the samples irradiated at a dose of 150 Gy. The biscuits were prepared with different ratios of the irradiated potato flour at dose 150 Gy to white flour. Sensory evaluation for biscuits with 10% of potato flour scored 8.61 ± 0.01, 8.33 ± 0.02, 8.77 ± 0.02, and 8.38 ± 0.00 for overall acceptance, colour, texture and appearance, respectively. This study recommends using 10% of irradiated potato flour at 150 Gy blended with wheat flour to produce biscuits.

Yam (Dioscorea spp.) is a tuberous plant of high energy and nutritional value, with great importance for the industry and as a food because of its composition. With the purpose of developing bakery products and determining its acceptability, cake, biscuit, pasta, pancake, bread, and pizza were prepared with 0 to 20% of starch in substitution for wheat flour. Yam starch was obtained when arriving at the industry in Caapiranga-AM, the flagship yam processing town in the region. Sensory evaluation was carried out by a target audience of 50 individuals, using a hedonic scale. For the statistical analysis, the Tukey’s test was used, and it was found that in the overall analysis, the best treatments were the control (no yam starch) and the one with 5% of yam starch. The production of these byproducts is viable, adding value to yam and delivering a product with better quality to consumers.

Sweet Potato Flour

Purpose The purpose of this paper is to investigate the effect of partial substitution of wheat flour with sweet potato flour on the nutrient composition and sensory properties of bread. Design/methodology/approach Sweet potato flour was blended with wheat flour at 5, 10, 15, 20 and 25 percent levels of substitution for bread production. Proximate, minerals and antinutritional factors of the breads were investigated using AOAC methods. Sensory evaluation was carried out by a panel of 50 consumers. Data were subjected to analysis of variance and means were separated by Tukey’s comparison test at p <0.05. Results were reported as mean ± SD. Findings The nutritional and sensory quality of bread made from wheat flour supplemented with sweet potato flour at 5, 10, 15, 20 and 25 percent was investigated. Blending of sweet potato flour with wheat flour had significantly decreased the protein content (4.76–7.78 percent) while the ash (1.35–3.07 percent), crude fiber (0.24–1.03), carbohydrate contents (88.39–90.45 percent), iron, zinc, phosphorus and vitamin A contents were significantly increased ( p<0.05) with increasing sweet potato flour in the formulations. The tannin and phytate contents of the composite breads were low. Sensory evaluation of the breads revealed a mild reduction of the bread’s general acceptability with increase in the substitution level by sweet potato flour. Originality/value This study showed that the wheat flour used in making breads could be substituted with up to 15 percent sweet potato flour without compromising its nutritional quality, with only a mild reduction in sensory quality.

Purple Sweet Potato

The objective of the study was to determine the concentation ratio between purple sweet potato flour and wheat flour in order to produce purple sweet potato cookies having particular nutritional content and preffered by consumers. A completely randomized experimental design was applied in this study. One experimental factor which was ratio of purple sweet potato flur and wheat flour consisting five level of treatments, was as signed i,e 100%: 0%, 80:20%, 60%:40%, and 20%: 80% respectively. Variables measured were chemical composition (protein, fat, moisture, anthocyanin content) and sensory properties (colour, taste, texture, overall likeness). Results showed that most variables were influenced by the ratio of sweet potato flour and wheat flour, excluding moisture content. The ratio of 80% sweet potato flour : 20% wheat flour resulted in cookies with good characteristics and mostly preffered by parelists. Anthocyamin content of this particular cookies (80%: 20%) was similar to that of sweet potato flour.  Keywords: cookies, purple sweet potato flour, wheat flour   ABSTRAK  Penelitian ini bertujuan untuk menentukan konsentrasi tepung ubi jalar ungu dan tepung terigu yang tepat untuk menghasilkan kue kering ubi jalar ungu dengan kandungan gizi tertentu dan disukai.

Sweet potato and jackfruit seeds are local resources that can grow well in tropical climate of Indonesia that has a high level of productivity. Thus, food diversification program through the use of local resources is expected to address people's reliance on products of flour-based noodles. This study is divided into three main stages, namely formula optimization, analysis, and organoleptic. Optimization stage formula begins by determining the maximum and minimum points substitution of each flour. For jackfruit seed flour, sweet potato flour and wheat flour made wet noodle-making with the level of substitution of 10% to 80%. Analysis of the product consists of a physical analysis ie water absorption in the range of 8.5% to 9.5%. Chemical analysis of water content with the result of 0.83% to 0.97%, Abu 0.0087 to 0.0094 levels, protein content of 8.5% to 9.5%, fat content of 0.0075 to 0.0084, starch 27.74 until 27.78, crude fiber 0.02 to 0.07, and a yield of 1 to 1.7. The solution formula with the most optimal response,ie wet noodle formula with 33.33% jackfruit seed flour, sweet potato flour 33.33%, 33.33% wheat flour
