scholarly journals Optimization and Development of Gluten-free Noodles from Foxtail Millet using Response Surface Methodology

The current study is being conducted to optimize the use of Composite flours of Wheat and Foxtail millet, Guar gum through Response Surface Methodology (RSM) to pro duce gluten-free millet noodles. For the current research, the base materials such as wheat flour (40-80 g), Foxtail millet flour (20-60g) and Guar gum (0.50-1.00 g) assumed as independent variables which are optimized after performing RSM .The following responses are predicted for Gluten content, Glycemic index, cooking loss, cooking time and Sensory traits. 17 Exceptional combinations are generated within the experimen tal design and are analyzed in order to know the influence of inde pendent variables on responses.The values of processed raw mate rials such as wheat flour, foxtail millet flour and guar gum are re spectively obtained as 60 g, 40 g and 0.75 g.The Gluten content, Glycemic index, cooking loss, Cooking time and sensory characteristics are found 14 g, 49 index, 10 min, 12.6 % and 5, respectively.

Abstract In this study, the possible usage of chestnut flour in gluten-free cake formulation was investigated. Response surface methodology was used to evaluate the effects of water, xanthan and guar gum mixture and potato starch. Crust and crumb attributes, sensory and textural properties of the cake samples were investigated. Considering all cake properties, better results were obtained by increasing xanthan gum in the gum blend. Increasing the amount of potato starch in the chestnut flour–potato starch blend decreased the batter density, consistency, hardness and chewiness, but increased the specific volume, cohesiveness and scores of the interior and exterior attributes. Optimum concentration of gum mixture was found as 0.225% xanthan gum, 0.075% guar gum and ratio of chestnut flour to potato starch was 7:3. Then, four different levels of transglutaminase were added to control and optimized gluten-free cake formula. The highest desirability value was obtained in gluten-free formula containing 0.25% transglutaminase. According to the results of the sensory analyses, no significant difference was observed between control and gluten-free cake.

The purpose of this study was to develop non wheat millet pasta. Box Benhken Design (BBD) under Response Surface Methodology (RSM) was used to find the better composition by considering cooking quality parameter such as cooking time, solid gruel loss, volume expansion and bulk density. Pasta was prepared using tapioca flour, foxtail millet flour and barnyard millet flour, corn flour, water and salt. The corn flour and the salt quantities were kept constant and the remaining flours varied. The dough prepared manually and extruded using cold extruder followed by it was steamed at 80ºC for 10 min and dried at hot air oven at 60ºC. Ingredients were optimized based on derringer’s desirability function. The optimized composition was found to be tapioca flour (50%), foxtail millet flour (24.6%) and barnyard millet flour (65.78 %), at this composition cooking time was 7.17 min, solid gruel loss was 6.198%, volume expansion was 6.99%, bulk density was 321.95kg/m3, carbohydrate was 71.5%, protein was 4.6% and fat was 1.1% with the desirability of 0.829.

Необходимость разработки безглютеновых продуктов обусловлена ростом численности людей страдающих целиакией, распространенность которой составляет 1 случай на 100–200 человек населения. Решение проблем, возникающих при производстве безглютеновых мучных кондитерских изделий, делает актуальным поиск новых видов сырья, не содержащего глютен и способного улучшать потребительские свойства изделий. В качестве источника безглютенового сырья была выбрана гречневая мука (ГМ). Получено безглютеновое печенье из ГМ в сочетании с различными гидроколлоидами – камедями акации, трагаканта, гуаровой и ксантановой, которые по отдельности добавляли в образцы ГМ в количестве 1г/100 г, и исследовано его физико-химические и сенсорные свойства в сравнении с аналогичными свойствами печенья из пшеничной муки (ПМ). Установлено, что образцы ГМ с добавкой камедей имеют более высокое содержание влаги, а печенье, полученное из смеси ГМ с камедью по разработанной нами технологии, – большую толщину, массу и сниженную прочность при разрушении по сравнению с ГМ и печеньем, изготовленным из нее. При сенсорной оценке качества изделий, проведенной по девятибалльной гедонистической шкале, установлено, что самые высокие показатели качества имеет печенье из ПМ, самые низкие – печенье, приготовленное из ГМ. Внесение камедей улучшило сенсорные показатели изделий на основе ГМ. Лучшим признан образец печенья на основе ГМ с добавлением ксантановой камеди. Таким образом, использование гидроколлоидов улучшает водосвязывающую способность муки и сенсорные показатели изделия – цвет, аромат, вкус и дает возможность получить безглютеновое печенье достаточно высокого качества, сопоставимого с качеством печенья из пшеничной муки. The need to develop gluten-free products is due to the growing number of people suffering from celiac disease, the prevalence of which is 1 case per 100–200 people of the population. Solving the problems that arise in the production of gluten-free flour confectionery products makes it relevant to search for new types of raw materials that do not contain gluten and can improve the consumer properties of products. Buckwheat flour (BF) was chosen as a source of gluten-free raw materials. Gluten-free cookies from BF were obtained in combination with various hydrocolloids-acacia, tragacanth, guar and xanthan gums, which were separately added to BF samples in the amount of 1 g/100 g, and its physical and chemical and sensory properties were studied in comparison with similar properties of wheat flour cookies (WF). The purpose of this work is to obtain gluten-free cookies from BF in combination with various hydrocolloids – acacia gum, tragacanth, guar gum and xanthan gum, which were separately added to BF in the amount of 1 g/100 g, and to study its physical, chemical and sensory properties in comparison with similar properties of cookies from WF. It was found that the samples of BF with the addition of gums have higher moisture content, and the cookies obtained from a mixture of BF with gum according to the technology developed by us – a greater thickness, weight and reduced strength at destruction compared to BF and cookies made from it. In the sensory evaluation of the quality of products conducted on a nine-point hedonistic scale, it was found that the highest quality indicators are cookies made from WF, the lowest – cookies made from BF. The introduction of gums improved the sensory performance of BF-based products. A sample of BF-based cookies with the addition of xanthan gum was recognized as the best. Thus, the use of hydrocolloids improves the water-binding ability of flour and the sensory characteristics of the product – color, aroma, taste, and makes it possible to obtain gluten-free cookies of sufficiently high quality, comparable to the quality of cookies made from wheat flour.

The aim of this research was to optimize the processing of dried sago noodle. Sago noodle was made through a process using twin screw extruder with the addition of GMS (Glycerol Monostearate) and ISP (Isolated Soybean Protein).Process optimation was performed with RSM (response surface methodology) using three process variables, i.e. extruder temperature (65-80oC), GMS concentration (0-5%), and ISP concentration (0-10%). The optimum processcondition was temperature of 80oC, GMS of 4.5%, and ISP of 3.7%. The optimum condition produced dried noodlehaving a hardness of 2499.62 gf, stickiness of 235.12 gf, elongation of 168.96% and cooking loss of 6.23%.Keywords: Noodle, sago, starch, optimization ABSTRAKPenelitian ini bertujuan melakukan optimasi proses pada pembuatan mi sagu untuk menghasilkan mi sagu dengan karakteristik fisik yang baik.
