The present work was aimed to prepare dried vegetarian soup supplemented with some legumes. Potatoes, hull-less barley flour, carrot, tomatoes, onion, garlic, salt, black pepper, coriander and cumin (served as F 1) were used in combination with lentil, green pea and chickpea to formulate F 2 , F 3, and F 4 , respectively. Chemical, physical, rheological and sensory evaluation was performed. The results indicated that supplementation with legumes significantly enhanced the nutritional characteristics, where the dried vegetarian soup mixtures had reasonable amounts of the required nutrients particularly, protein, carbohydrates, fats, Fe and Zn with good in vitro protein digestibility and mineral availability. Moisture content and water activity predicted the extended shelf-life and stability of the dried soup mixtures. The four resultant soup samples F 1 , F 2 , F 3 and F 4 had a noticeable viscosity pattern characterized by a non-Newtonian pseudoplastic flow behavior. Supplementation with legumes significantly (p ≤ 0.05) affects taste, color, flavor attributes and overall acceptability of the resultant soup samples. But, it had no significant effect on thickness and appearance. The results clearly demonstrated the usefulness of supplementing the dried vegetarian soup mixtures with legumes to enhance nutritional and technological quality of the resultant soup and lentil was the most valuable addition with the highest acceptability.

The purpose of this paper is to investigate some quality attributes of low fat ice cream (LFIC) substituted with hulless barley flour (HBF) and barley ß-glucan (BBG). The methodology included in this paper is based on adding HBF (1, 2, 3 and 4 %) as a partial substitution of skim milk powder (SMP) and BBG (0.40 %) as a complete substitution of carboxy methyl cellulose (CMC). All mixes and resultant ice cream samples were evaluated for their physicochemical properties as well as the sensory quality attributes.The results indicated that substitution of SMP with HBF significantly increased total solids (TS), fat and crude fiber, while crude protein and ash significantly decreased in ice cream mixes. BBG exhibited the same manner of control. Specific gravity was gradually increased with adding HBFand BBG in the mixes and therefore the overrun percent was significantly changed in the resultant ice cream. Adding HBF in ice cream formula led to significant decrease in acidity with higher freezing point and the product showed higher ability to meltdown. BBG treatment showed the same trend of control. Values of flow time and viscosity significantly increased with increasing HBF in the ice cream mixes, but these values significantly decreased in BBG mix. The time required to freeze ice cream mixes was decreased with increasing the ratio of HBF but, increased in BBG treatment. The substitution of SMP with 1 and 2 % HBF significantly (P ≤ 0.05) enhanced sensory attributes of ice cream samples. While, BBG treatment achieved mild score and acceptability.

The influence of incorporating dry-heated wheat bran, at 5, 10, 15, and 20 g/100 g levels with dry-heated wheat germ at 3 g/100 g level, on fino dough rheology and bread quality was studied in comparison with fino bread containing unheated fractions, and white wheat bread. Dry heat treatment showed insignificant effects on the chemical composition and the dietary fibers of wheat bran and wheat germ, but was effective in reducing lipase activity by half in wheat bran, and by 100% in wheat germ. Dough containing dry heated fractions lowered the water absorption, extended the development time, strengthened the protein network, and increased the stability time, starch gelatinization, hot-gel stability, and starch retrogradation. Fino bread had larger loaf volume, darker crumb color, and lesser firm, gummy, and chewy texture. Sensory acceptability of fino bread loaves containing heated fractions indicated significant (P B 0.05) improvement in taste, flavor and overall acceptability scores. Fino bread provided 9.0 to 21.5% of the dietary fiber intake (DFI) for the adults, showed significant loss of phytic acid (30-34%), had higher significant total phenolic contents (109.2-198.2 mg GAE/100 g), and antioxidant activity (40.17-47.46%). Levels of 10 and 15 g heated bran with 3 g heated germ/ 100 g showed acceptable results among all studied characteristics. Dry heat treatment could be applied on wheat bran and wheat germ to mitigate their negative influences on dough rheological behavior, and to deliver functional fino bread to consumers, with more dietary fiber, highquality nutrients and antioxidant activity.

Three hulless barley varieties were grown under normal conditions during 2017/2018 and 2018/2019, to improve their agronomic yield, and to assess how the genotype influences β‐glucan contents, and its structural, thermal, rheological, and functional properties, as intended to be used in food applications. The extracted gums with hot water at 55 °C and pH 8.0, showed contents from 5.75% to 6.41% (w/w), and concentrations from 68.55% to 79.29% of β‐glucan, with some starch and protein impurities. The results of the agronomic trail indicated the highly significant (P ≤ 0.01) influence of the genotype on all studied characteristics, and on the β‐glucan contents (0.28** and 0.33**) at both seasons. The morphology of the three gums was significantly different in the distribution and structure of networks. Peak intensities of the –OH and –CH groups and CH2 stretching were higher and wider in Giza129 and Giza131. β‐Glucan networks melt from 71.5 to 87.18 °C, and Giza131 exhibited the highest thermal stability. The aqueous dispersions (1%) of β‐glucan gums exhibited a non‐Newtonian behavior, and Giza130 presented the highest significant (P ≤ 0.05) apparent viscosity (η) and foaming stability. Giza129 showed the highest significant water and fat binding capacities, whereas Giza131 showed the highest significant foaming capacity. β‐Glucan gums showed different potentials in food applications as fat replacers, stabilizers, thickeners, and foaming agents in food systems. This study suggests planting the proper barley variety in breeding and genetic improvement programs to supply the food industry with the expected β‐glucan content with consistent structural, thermal, rheological, and functional properties. Practical Application β‐Glucans play an important technological role in processed foods. Little current information is available on β‐glucan contents, and its potentiality on food applications, as influenced by variability among hulless barley genotypes. Accordingly, knowledge of β‐glucan levels in barley varieties is a valuable attribute for both consumers and food processors, and it will create an opportunity for scientific cooperation between food technologist and breeders to identify the suitable barley varieties to be used in breeding programs, to obtain barley with required β‐glucan contents, targeted for specific end uses.

Purpose -The purpose of this paper is to investigate the potential quality of Kamut s (triticum turgidum turanicum) as an ancient relative of modern durum wheat for food preparation and Egyptian consumption. Design/methodology/approach -The methodology included in this paper is based on quality evaluation of Kamut wheat of the Dashure-Fayume geographical origin physically, chemically and technologically compared to Beni Suef 1, Beni Suef 3 and Suhag 3, the most dominant durum varieties in Egypt. After that, producing a specific end product (traditional couscous) regarded the critical quality aspects in Kamut wheat. Findings -The results obtained showed that Kamut grains had higher physical properties indicating higher milling yield potential. Besides, Kamut flour was remarkable with higher protein and oil content. The use of a farinograph for assessing the rheological properties of Kamut dough has proven a useful quality for its measured characteristics compared to the Egyptian durum varieties. The good physical and rheological properties, coupled with high protein content, validated that Kamut is a valuable addition to the Egyptian diet and suited for the production of pasta and/or couscous. The sensory attributes of traditional couscous were significantly (po0.05) highly acceptable to the panelists. Originality/value -These results lead to valuable addition and improvement of the Egyptian diet which consider The Sustainable Agricultural Development Strategy (SADS) towards 2030 in Egypt based on achieving higher rates of food security in strategic goods in regard to improve food quality and safety, especially Kamut wheat which produces high quality grains without artificial fertilizers and pesticides.

Abstract:The aim of this study is to produce Gluten-Free rolled paper from broken rice by using different hydrothermal treatments. Pressure parboiling, dry roast parboiling, and popping treatments were applied to enhance the functionality of lowamylose broken rice flour. The effects of hydrothermal treatments on the morphological, physicochemical, as well as sensory properties of the produced Gluten-Free rolled papers were studied. Morphological examination of hydrothermal treated flours showed gelatinized and enlarged starch granules with different shapes, and fractures in the surface, especially in dry roasted parboiled flour. For chemical composition (g/100g), protein (6.7 -3.57), total starch (81.67-76.36) and amylose (17.27 -14.18) significantly decreased in rice papers produced from hydrothermal treated flours, while fat (1.67 -1.82) and ash (1.62 -2.68) significantly increased. In vitro starch digestibility showed a significant increase (80 -99.73 g glucose/ 100g) in rice papers produced from dry roast parboiling and popping treatments. Rice paper batters produced from hydrothermal treatments had a noticeable viscosity pattern characterized by a non-Newtonian pseudoplastic flow behavior. A significant reduction in lightness value (89.77 to 60.42) occurred, while a significant increase in redness (0.33 to 1.54) and yellowness (3.75 -20.59) values were observed in all rice papers produced from hydrothermal-treated flours. Tensile strength (0.14 -0.36 N/mm 2 ) and % elongation at break (43 -57%) significantly increased in rice papers produced from parboiling treatments, while fracture toughness increased (2.76-5.51 N/mm 3/2 ) in rice paper produced from popping treatment. Sensory evaluation indicated significant improvement in freshness, rollability, and the overall scores in rice papers produced from parboiling treatments. Results could be a value addition for processing of low-amylose broken rice flour and delivering high quality rice paper to consumers who are more concerned about Gluten-Free products.
