Wild Almond

This research aimed to investigate the quality of fruit bars prepared with different ratios of sapodilla-wild almond seed (80:20 and 70:30 w/w) and sugar substitution with stevia (0, 1/3, and 2/3 as equivalent sweetness basis). Physical properties (moisture and water activity), sensory acceptability, and preference mapping of the fruit bars were investigated. The samples formulated with a higher proportion of sapodilla pulp had higher moisture and water activity than those with less sapodilla pulp. Increasing the sugar substitution with stevia tended to decrease the moisture and water activity of the fruit bars. The stevia incorporation had effects on sensorial attributes, especially the flavor depending on how much sapodilla pulp proportion used in fruit bar preparation. The fruit bars formulated with 80:20 of the sapodilla-wild almond seed and 2/3 sugar substitution and that with 70:30 and full-sugar perceived the highest overall acceptability. The preference mapping revealed the importance of product attributes, and the texture was an important attribute on sensorial acceptance. In conclusion, the fruit bar prepared with 80/20 of sapodilla-wild almond seed and 2/3 sugar substitution with stevia was the most preferred formulation.

Gluten free products remain the cornerstone for celiac patients. Insufficiency, poverty and little offered about gluten free products (quality and quantity) represented a high obstacle for Egyptian celiac patients. Therefore, the purpose of this research is to modify a single screw extruder to produce gluten–free pasta (GFP) (tagliatelle type). The GFP was made from corn flour under screw rotation speed (N) of 10, 25 and 50 rpm at 40, 65, 90 and 115 ºC of barrel temperature (BT). Extruder performance was evaluated as specific mechanical energy (SME) and expansion ratio (Er). The cooking quality of GFP as optimum cooking time (OCT), cooked yield (CY), swelling (Sw), cooking losses (CL) and sensory characteristics (appearance, colour, taste, mouth feel and overall acceptability) were evaluated. The better results of the GFP sensory evaluation were obtained at BT= 80 ºC, N =25 rpm and Er ≈ 1.38 with OCT ≈ 3.3 min, CY= 196%, Sw = 210% and CL= 16.3%. All parameters were given a direct proportion with processing variables N and BT, except CL. Furthermore, it can be predicted cooking properties values for GFP by SME value using the following equation; SME » 1.8675 (Er) + 0.8037 » 0.0608 (OCT)1.5984  » 8×10-17 (CY)6.7878 » 2×10-9 (Sw)3.494  » -0.0306 (CL) + 0.7877.

Positive Effects

Effects of partial replacement of wheat flour with corn flour (2.93–17.07%) blended with xanthan gum (0.1172–0.6828%) on physical properties, textural and sensory characteristics of sponge cakes were evaluated by response surface methodology (RSM). The significant regression models (P ≤ 0.05) were established to explain the influence of corn flour and xanthan (Xan) on the dependent variables and optimize the formulation. Xanthan significantly increased moisture content, hardness and chewiness, but it decreased specific volume and springiness (P ≤ 0.001). Corn flour had significant positive effects on specific volume, hardness, springiness, colour and overall acceptability (P ≤ 0.05). Hence corn flour and xanthan significantly improved the baking quality of sponge cakes (P ≤ 0.05) and thereby augmented the potential for using wheat-corn blend flours in cake baking. Based on RSM optimisation, a balance between amounts of corn flour (12.7%) and xanthan (0.416%) led to products with desired physical properties and acceptable sensory quality.

Flat breads are popular all over the world. There are several forms of flat bread, which differ in their methods of preparation. In comparison to pan breads, the leavened flat breads have shorter fermentation period. Nowadays, the use of additives has become a common practice in the baking industry. In this paper, supplementation of several hydrocolloids having different chemical structure and diverse origin to the flatbread making process is presented. Hydrocolloids comprise a number of water-soluble polysaccharides providing a range of functional properties that make them suitable to this application. They provide proper texture, control moisture, improve overall product quality and stability, reduce cost, and facilitate processing in the flat breads. Various gluten-free formulations have applied hydrocolloids to mimic the viscoelastic properties of gluten. Hydrocolloids have been used for retarding the staling and for improving the quality of the fresh products. In addition to this, good sensory properties for visual appearance, aroma, flavor, crunchiness, and overall acceptability were obtained.

This study aims to investigate the potential of white and bronze whole-grain sorghum flour to develop gluten-free bread (GFB) with acceptable sensory properties. Two 22 factorial designs, with two central point repetitions each, were used to study the effects of white (WS) or bronze sorghum (BS) flours and water (W) levels on the physical properties, acceptability scores, and proximate composition of GFB. The WS or BS levels ranged from 50 to 100% when blended with potato starch, and the W levels ranged from 100 to 140% (flour weight basis). Independent of the amount applied, GFB formulations containing BS were well accepted (acceptability scores for appearance, color, odor, texture, flavor and overall liking ≥ 6.29 on a 10 cm hybrid hedonic scale). No significant differences were observed between the acceptability scores of single and composite formulations for all of the evaluated sensory attributes. Moreover, the W levels had no effect on the acceptability of GFB made with BS. Composite formulations prepared with 50 and 75% WS were also well accepted (acceptability scores for appearance, color, odor, texture, flavor, and overall liking ≥ 7.43 on a 10 cm hybrid hedonic scale). However, increased W levels are required in single formulations to increase the scores for texture and overall acceptability. GFB made with 50% and 75% WS/BS can be classified as a source of fiber since the fiber content is higher than 3 g per 100 g, while GFB made with 100% WS/BS can be classified as high in fiber, as the content of this component is higher than 6 g per 100 g. This research highlights the great potential of whole-grain sorghum flours for producing nutrient-dense and acceptable GFB, which is important for consumers who choose or must adhere to a GF diet.

Orange Fleshed Sweet Potato

Background Protein-energy deficiency (PEM) is still a major health issue in developing countries, and it is the leading cause of disease and death in children under the age of 5 years. Methods 100:0:0; 90:5:5; 80:10:10; 70:15:15; 60:20:20; and 50:25:25 per cent wheat:haricot bean: orange-fleshed sweet potato (OFSP) flours were used to make composite cookies. Standard methods were used to evaluate the proximate structure, physical properties, and sensory assessment. A one-way analysis of variance (ANOVA) model was used to statistically evaluate the data using the statistical analysis system (SAS) software package, version 9.0 standard methods. Results The results showed that partially replacing wheat with haricot bean and OFSP increased the proximate composition significantly. When wheat was replaced with haricot bean and OFSP, the physical characteristics of the biscuits did not vary significantly from those of biscuits made entirely of wheat flour. Sensory acceptability (appearance, color, flavor, taste, and overall acceptability) was higher in the composite biscuits with up to 40% wheat substitution than in the 100% wheat flour biscuits. Conclusions Based on the findings of this report, using OFSP and a haricot bean to wheat flour blend in biscuit formulation appears to be promising in terms of nutritional quality, acceptability, and cost. It is proposed that these products be marketed to vitamin A deficiency (VAD) customers as a newly established product to help mitigate food insecurity.
