Purple water yam tubers (PWYTs) or Dioscorea alata are edible tubers containing bioactive compounds that are beneficial to human health. Its high carbohydrate content can be used to make flour or starch to increase its shelf life and food diversification. However, this food is unpopular among several communities in Indonesia, particularly for the juveniles due to limited processing knowledge. Therefore, this study aims to characterize the physicochemical properties of purple water yam flour (PWYTF) and starch (PWYTS) in order to assess consumers' acceptability toward gluten-free cookies. The PWYTF was prepared by drying peeled tubers, which was subsequently grounded. Meanwhile, the PWYTS was prepared by homogenizing the peeled tubers with water, the sediment from supernatant was dried. The chemical properties, such as moisture, ash, fiber, protein, and lipid, were determined using the Indonesian national standard procedures for flour. The physical properties, namely pH, bulk density (BD), water/oil absorption capacity (W/OAC), water/oil binding capacity (W/OBC), swelling power (SP) and solubility (Sol) were evaluated. The PWYTF and the PWYTS were used to make gluten-free cookies, with their physical properties and consumer's acceptability evaluated using semi-trained panelists. Yields of both the PWYTF and the PWYTS were 36.10% and 26.63%, respectively. The chemical compositions of the PWYTF and the PWYTS were significantly different (p0.05) for carbohydrate (80.34 and 80.78 %), crude protein (0.78 and 0.81%), and crude fiber (2.0 and 1.9%) except for the ash content (2.6 and 0.5%), lipid (0.3 and 0.1%), and moisture (13.77 and 15.70%). Furthermore, their physical properties were also significantly different (p0.05) for pH (6.62 and 5.84), BD (0.46 and 0.68 g/mL), WAC (2.07 and 0.46 g/g), WBC (1.07 and 0.49 g/g), SP, and Sol except OAC (1.63 and 1.49 g/g) and OBC (0.63 and 0.49 g/g). The cookies made from the PWYTS were appreciated with the highest hardness and rated from panelists. Therefore, the PWYTS can be used in place of a commercial wheat flour to make cookies..

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.

Purpose The preparation of gluten-free bread is a challenge because the gluten in wheat is the main ingredient responsible for the retention of the gases which cause the bread to rise. This paper aims to develop breads without gluten and fat, and to evaluate the effect of the use of chia (Salvia hispanic L.) flour on the physical, nutritional and sensory properties of the breads that were developed. Design/methodology/approach Three formulations were developed with different proportions of chia flour (2.5, 5 and 7.5%), fat-free. Physiochemical, sensorial analyses were performed out in three repetitions (p-value = 0.05). Findings In the nutritional assessment, the results demonstrated that 7.5% chia showed higher levels of protein (15.1%), lipid (3.43%), total fiber (7.04%) and lower levels of carbohydrates (22.49%), with significant nutrient enrichment (p-value = 0.05). The specific volume and the elevation of the dough decreased with the addition of chia flour. In the sensorial analysis, the treatments with chia flour showed no significant difference regarding flavor and texture when compared to the standard. The addition of chia improved the nutritional and sensory properties (p-value = 0.05). Originality/value The chia flour improved the nutritional characteristics of the breads, in the reduction of carbohydrate content and the increase in the content of protein, minerals and fiber. It presented good acceptability and good nutritional characteristics, providing a healthy and differentiated variation in this segment.
