Date Seed, Oat Bran and Quinoa Flours as Elements of Overall Muffin Quality

Muffins are desirable bakery products both for their sensorial properties and for ease to be baked with numerous ingredients. Flours of date seed (D), oat bran (O) and quinoa (Q) with different insoluble dietary fibre contents were used in this study, as substitutions to wheat flour either individually (10%, w/w) or as combinations (5% each, w/w) in muffin samples. Suggested combined usage of ingredients aimed to increase the dietary fibre content of muffins while pertaining their overall quality attributes. Total moisture, ash and protein, dietary fibre, weight loss %, volume, specific volume, weight, colour and textural parameters were tested. Results revealed that, quinoa and oat bran flour substituted samples (QO) had the highest cake volume (84.5 ml) and specific volume (2.63 ml/g). Date seed and quinoa flour substitution (DQ) was the best combination with the closest hardness values to control (muffins with 100% wheat flour) samples (0.6 N), rather than an increase. Springiness (2.40 N) and cohesiveness (0.81 mm) were also close to that of control. Samples having date seed flour and quinoa (DQ) and date seed flour and oat bran flour (DO), had also the highest fibre contents, respectively. Thus, combining different fibrous ingredients instead of using them individually efficiently prevented the muffin quality loss. The best combination achieved was the date seed flour with quinoa flour (DQ) giving promising results to achieve healthier muffin production.

Study on the Effect of Xylitol and Maltitol as Alternative Sweeteners in Sponge Cakes

Background: As the main sweetener in sponge cakes, sucrose provides not only energy and structure, but also acts as a stabilizer and tenderizer. Due to its high-calorie content, alternative sweeteners such as xylitol and maltitol are used in its place. Objective: The purpose of this study is to substitute sugar with xylitol and maltitol in sponge cake. Methods: In this study, the possibility of producing sugar free sponge cakes with xylitol and maltitol was evaluated (control: 100% sucrose, M1: 100% xylitol, M2: 75% xylitol-25% maltitol, M3: 50% xylitol-50% maltitol and M4: 25% xylitol- 75% maltitol). Sensory evaluations and physicochemical properties of the final product such as water activity, moisture content, firmness, cake volume, crust color and sensory analyses were determined. Results: Based on the results obtained from the four samples, M3 and M4 resulted in a significant decrease in volume. The highest specific volume was obtained in M2. The last two samples, M1 and M2 showed lower water activity than the control. In addition, the highest dark crust color was obtained in M1. M2 produced a softer texture and thus produced cakes with the highest flavor. Conclusion: The results of the study showed that complete substitution of sucrose with 75% xylitol and 25% maltitol (M2) produced samples with similar crust color, firmness, volume and porosity in comparison with control cakes.

Characteristics of Coconut (Cocos nucifera) Flour and Its Application in Cake

Aims: The aim of the study was to evaluate the physicochemical, sensory and functional properties of coconut flour (CF), coconut wheat composite flour (CWCF) and Cake produced from CF and CWCF. Methodology: Flour was prepared from matured ripe coconut fruit (CF). It was then blend with wheat flour (WF) into coconut wheat composite flour (CWCF) to produce cake. The CF and CWCF were subjected to proximate composition and functional properties analyses. Also, the physical properties, proximate composition and the sensory attributes of the cakes produced from CF and CWCF were determined. Results: The moisture content of CF and CWCF ranged from 4.5 to 9.04 g/100 g, the ash content of CF and CWCF ranged from 4.10 to 6.41 g/100 g and the dietary fiber content of CF was 11.16 g/100 g. CWCF exhibited a higher (87.1± 0.6) water absorption capacity and packed bulk density (0.79 ± 0.3 g/ mL). In this study, the cake volumes increased significantly (P < 0.05) in wheat flour (WF) as compared to CWCF and CF. The specific cake volume observed ranged from 1.48 to 2.01 mL/g. The blend of 50% coconut and 50% wheat flour increased significantly (P < 0.05) the moisture content of the CWCF cakes. The total carbohydrate content of the cakes varied from 20.40 ± 0.02 g/ 100 g to 63.05±0.14 g/ 100 g. Fat, ash and crude fiber and minerals (Ca, K, P Zn, Mg and Fe) increased in CWCF cakes. The sensory analysis conducted showed that there was a significant difference (P < 0.05) between CF cakes, WF cakes and CWCF cakes in the sensory qualities of appearance, texture, flavour and overall acceptability. In terms of appearance, the panelists scored coconut cake highest, but was significantly different (P < 0.05) from coconut wheat cake and wheat one. The least liked sample in terms of texture was wheat one. Conclusion: The present study underscored the potential application of coconut flour in the production of cake and possibly other bakery products.

Batter Rheology and Quality of Sponge Cake Enriched with High Percentage of Resistant Starch (Hi-maize)

Addition of resistant starch (RS) to foods improves their health benefits. However, quality and sensory properties of the products are scarified when high amounts of RS (>20%) are added. The main purpose of this study was to develop an acceptable cake containing high level of RS (>20%) and to fix the associated problems by addition of gluten powder. Wheat flour was replaced with 30%, 40% and 50 % of reconstituted flour; a mixture of RS and gluten powder (9:1, w/w) and some quality aspects of the batter and cakes were studied. With increasing the RS+gluten levels, pasting temperature increased while peak and final viscosities decreased. Batter density, viscosity, storage and loss moduli reduced whereas the size of air bubbles increased. Cake volume, height, porosity and hardness reduced, while the crust lightness and crumb darkness increased. Based on the sensory analysis a maximum of 40% RS+Gluten resulted in an acceptable cake quality.

Effect of Green Banana Peel Flour Substitution on Physical Characteristics of Gluten-Free Cakes

Celiac Disease is the most common food-sensitive entoropathy in humans that is triggered by the consumption of wheat gluten as well as related with protein in barley, rye and oat. The only treatment ever known for celiac disease is gluten-free diet. Most gluten-free food product on the market is rich in starch but poor in terms of other nutrients, functional and health benefitial ingredients. Green (unripe) banana is a good source of resistant starch, non-starch polysaccharides including dietary fiber, antioxidants, poliphenols, essential minerals such as potassium, various vitamins e.g. provitamin A, carotenoid, B1, B2, C which are important for human health. In this research, it is aimed to develop nutritious and functional gluten free cake formulations by substituting green banana peel flour (GBPF) with rice flour (5%, 10%, 15% and 20%) and to investigate physical properties of GBPF substituted cakes. Cake volume, specific volume, density, baking loss and height of the cakes were in the range of 831.44 – 1034.11 cm3, 1.91-2.41 cm3/g, 0.41-0.52 g/cm3, 16.38-18.14% and 4.36-5.77 cm respectively. As a result, GBPF substituted gluten free cakes were successfully produced. Physical analyses of gluten free cakes showed that 5% and 10% GBPF substitution did not affect gluten free cake volume, specific volume, density and baking loss negatively. 5% and 10% GBPF substituted cakes were not different from control cake statistically (p>0.05). However, substitution levels of 15% and 20% resulted in poorer physical properties. Sensory analysis (data not shown) indicated that all GBPF substitution levels were acceptable, as determined by hedonic scala tests. By developing a nutritious gluten free cake alternative, it is expected to provide an alternative in the dietary diversity of individuals with celiac disease.

Cake Flour Chlorination and Alternative Treatments (Review)

In order to produce satisfactory cake, ingredients must be balanced accurately. Flour acts as building structure that contributes in the crumb properties. Chlorine treatment of soft wheat flour has been widely used since the 1920s. The functional effect of chlorination is partially de-polymerizing and oxidizing of flour starch. Oxidized starch granules are able to swell more rapidly after the starch reaches the gelatinization temperature and the resulting batter system will be adequately viscous to support the cake’s structure without collapsing. Batter expansion is superior for treated flours, even at the lowest chlorination rate, than for untreated flour. Alternatives to chlorine treatment need to be developed because of the potential carcinogenic effect of chlorination. Egg albumin contributes strength to cake crumb and improves cake volume. Acceptable cake volume can be achieved by heating but the dryer, stiffer crumb that springs back upon compression is not produced by heated flours. Xanthan gum L-cysteine, and hydrogen peroxide plus peroxidase to heat-treated flour and obtained volumes equivalent to cakes produced using chlorine-treated flour. Ozone treatments also are applied in cake flour with some benefits instead of chlorination.

Effects of powder from white cabbage outer leaves on sponge cake quality

The main objective of this study was to develop high fibre cakes utilizing and valorising cabbage by-products - cabbage outer leaves. Cabbage outer leaves were dried and milled in order to produce cabbage leaf powder. The cabbage leaf powder was added at 0, 10, 20% into sponge cake. All of the samples were subjected to physicochemical analysis and sensory evaluation. Methods of descriptive sensory analysis were used for a comparative analysis of the sponge cakes with cabbage leaf powder and the cake without cabbage leaf powder. Addition of cabbage leaf powder in sponge cakes significantly affected the cake volume and textural properties. Springiness of cakes with cabbage leaf powder and crumb tenderness were lower, while the structure was stable at high loads, as expressed by lower shrinkage in comparison with the control cake. The nutritional value of the sponge cakes with cabbage leaf powder was lower than the control cake. The cells cakes modified by cabbage leaf powder were smaller and almost equal, uniformly distributed in the crumb, and at the same time had thicker walls. The cakes with addition of cabbage leaf powder showed the springiness and their crumb tenderness were lower, while their structure was stable at high loads. Control cake showed higher water-absorbing capacity compared to the cakes with 10 and 20% cabbage leaf powder.

Effect of Tiger Nut Residue Flour Inclusion on the Baking Quality of Confectionaries

Cakes and biscuits were prepared from blends of wheat and tiger nut residue flours produced using raw and dry extraction method and substituted at 5%, 10%, 15% and 20% levels. The cakes and biscuits were analyzed for proximate composition, physical characteristics and sensory properties. Results for proximate composition indicated that moisture, fibre, ash, protein and fat contents increased with an increase in tiger nut residue substitution. Ash content for cake increased from 0.93% in sample A (100% wheat flour) to 1.40% in sample E (80% wheat flour: 20% tiger nut residue flour), while ash for biscuit increased from 1.35% in sample A (100% wheat flour) to 1.85% in sample B (95% wheat flour: 5% tiger nut residue flour). Fibre content for cake increased from 1.08% in sample A (100% wheat flour) to 3.15% in sample E (80% wheat flour:20% tiger nut residue flour) as substitution increased, while for biscuit fibre increased from 1.59% in sample A (100% wheat flour) to 3.13% in sample D (85% wheat flour:15% tiger nut residue flour). Moisture content for cake increased from 21.95% in sample A (100% wheat flour) to 28.49% in sample E (80% wheat flour: 20% tiger nut residue flour) while for biscuit moisture increased from 1.08% in sample A (100% wheat flour) to 2.78% in sample B (95% wheat flour: 5% tiger nut residue flour). There was a statistical significant difference in all samples with increase in substitution. Result for physical characteristics showed a significant (p ≤ 0.05) increase in cake volume and spread ratio of biscuit with increase in level of substitution of tiger nut residue flour. Sensory evaluation result for cakes showed sample E (80% wheat flour:20% tiger nut residue flour) as most acceptable for cakes, in terms of color (4.3), aroma (3.95), taste (4.2), texture (4.05) and general acceptability (4.3) while for biscuits sample B(95% wheat flour:5% tiger nut residue flour) as most acceptable in terms of color (4.15) aroma, (4.0) taste, (4.15) texture (4.3) and overall acceptability (4.35).
