Abstract

Purpose

The study was aimed to compare the effect of three drying techniques viz., spray, freeze and hot air oven (HAO) drying on yield, nutritional parameters, minerals and physicochemical and morphological characterization of wild banana pulp (Musa balbisiana Colla).

Design/methodology/approach

Contents of carbohydrate was estimated by Anthrone reagent, protein by Kjeldahl, fat by Soxhlet, dietary fiber and ash by Association of Official Analytical Chemists (AOAC), minerals by Atomic Absorption Spectrophotometry, gross calorific value by Bomb calorimeter, moisture by moisture analyzer, water activity by water activity meter, morphological characterization by Scanning Electron Microscopy (SEM), statistical level of significance at p < 0.05 by ANOVA, predictive modeling by simple and multiple linear regression.

Findings

Freeze and HAO drying were standardized with matured (stage 2) and spray drying with ripe bananas (stage 6). Freeze drying showed highest yield (76.69 ± 0.15%), minerals viz., K (1175.67 ± 1.41), Fe (2.27 ± 0.09), Mg (120.33 ± 0.47), Mn (4.40 ± 0.28) mg/100 g, protein (7.53 ± 0.14%), lesser moisture (7.95 ± 0.01%), water activity (0.17 ± 0.02aw), hygroscopicity (6.37 ± 1.09%), well dispersed particles by SEM. HAO drying exhibited highest dietary fiber (18.95 ± 0.24%), gross calorific value 357.17 kcal/100 gm, higher solubility (47.22 ± 0.86%). Spray drying showed highest carbohydrate (85.29 ± 0.01%), lowest yield (28.26 ± 0.32%), required 30.5% adjuncts.

Research limitations/implications

Effect of three drying techniques and use of adjuncts were not uniform for ripe and matured bananas.

Practical implications

Commercial utilization of seeded wild banana.

Social implications

Value addition of wild banana in Assam, India

Originality/value

Freeze drying of mature wild banana pulp (M. balbisiana) was found as best technique utilizing lesser energy.

Abstract

Purpose

Malnutrition during childhood precedes growth failure and affects the child’s well-being later in life. This study aims to investigate the potency of iron-fortified klutuk banana (Musa balbisiana Colla) flour on growth parameters and fibroblast growth factor 21 (FGF21) expression in malnourished rat model.

Design/methodology/approach

Rats were allocated into normal control (NC), untreated malnutrition (MC), malnutrition + iron-fortified klutuk banana flour (IBF) and malnutrition + Indonesian Government-issued biscuit (GB). Malnutrition was induced by an isoenergetic low-protein diet for five weeks. The IBF and GB groups were supplemented with IBF 1.2 g/200 gBW and GB 1.2 g/200 gBW, respectively, via gavage daily for three weeks. The body weight and length, the levels of plasma and liver FGF21 and red blood cell indices were analyzed.

Findings

After three weeks of supplementation, the IBF group showed higher body weight (245 ± 13.6 g vs 201.8 ± 16.3 g; p = 0.0004) and length (20.9 ± 0.5 cm vs 19.8 ± 0.5 cm; p = 0.021) compared with the untreated group. The plasma FGF21 level decreased in the IBF group (p = 0.034). The IBF group altered mean corpuscular volume and mean corpuscular hemoglobin, suggesting the IBF might attenuate malnutrition-induced anemia. Overall, the IBF prevented growth failure in malnourished condition. This might be mediated by the suppression of FGF21 expression, along with the prevention of malnutrition and anemia.

Originality/value

This study provides preliminary information about the potential use of rarely consumed banana, klutuk banana, as a supplement to treat malnutrition. This study might help the developing countries to eliminate the widespread malnutrition in economically challenged communities.

The purpose of this paper is to determine the physicochemical and sensory properties of fish patties added with banana peel powder (BPP), Musa balbisiana.

Abstract

Purpose

The purpose of this paper is to determine the physicochemical and sensory properties of fish patties added with banana peel powder (BPP), Musa balbisiana.

Design/methodology/approach

Four different fish patty formulations were produced containing 0 per cent (BPP0) (Control), 2 per cent (BPP2), 4 per cent (BPP4) and 6 per cent (BPP6) of BPP (M. balbisiana).

Findings

The addition of BPP was shown to improve the hardness, cooking yield, water holding capacity (WHC) and redness (a* value) as well as the dietary fibre (DF) content (p<0.05). The BPP, however, also turned the fish patties darker (lower L*) (p<0.05). Sensory evaluation showed that fish patties with a concentration of 2 per cent BPP had the highest overall acceptability, whereas the concentration of 6 per cent BPP was found to be unacceptable compared to that of control sample (p<0.05). The declining sensory acceptability of fish patty with 6 per cent BPP is related to the harder texture and the darker color of the patties compared to the control sample (BPP0).

Originality/value

The addition of BPP can potentially improve the quality of fish patties in terms of textural properties (hardness) by increasing their WHC, reducing the cooking loss and enhancing the DF content.

Abstract

Purpose

The purpose of this paper is to show the dyeing effect of banana peel on polyamide fabric by using various mordants and to reveal alternatives to metallic mordants.

Design/methodology/approach

The simultaneous mordanting method was used in the dyeing process.

Findings

From environmental and economical points of view, this paper studies the use of a natural waste product in textile dyeing. Assessment of domestic organic wastes will provide new possibilities for valorization of biomaterials. It is concluded that colorimetric data are affected by the amount of plant used in extraction, amount and type of mordant and pH of dye bath. Tin II chloride ensured the lightest color shades. No alternative mordants could be presented to iron II sulfate and tin II chloride, as they generated completely different color shades. Acids can be an alternative to 0.8 g/L alum mordant. Ammonium sulfate and sodium acetate also generated similar colors to alum. Ammonium sulfate can be substituted for citric acid and alum. Banana peel can be considered as a natural dye source for polyamide elastane blend fabric.

Originality/value

Banana peel can be suggested as a natural colorant with good wash fastness for dyeing of polyamide elastane blend fabric.

Abstract

Purpose

This study aims to develop nutritious and functional gluten-free cakes for celiac patients by substituting rice flour with unripe banana peel flour (UBPF) (0%, 5%, 10%, 15% and 20%) and to propound some chemical, textural and sensorial properties of cakes. A secondary purpose was also to contribute to waste management of the banana products industry by reevaluating the peel.

Design/methodology/approach

One-way analysis of variance and Duncan’s multiple comparison test (p < 0.05) were used to determine differences among the mean values. Proximate analysis, color, texture profile analysis, antioxidant activity, mineral composition and sensorial analysis were carried out. Data was analyzed using SAS software. Cake production was carried out in three replications.

Findings

UBPF in this study had high protein (11.2%) and dietary fiber (18.3%) as well as high antioxidant activity. In all, 5%–20% UBPF-substituted cakes had enhanced dietary fiber (2.5%–3.7% dry matter), ash content (1.6%–1.9% DM) in comparison to control cake (1.4% and 1.4%, respectively). 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity of enriched gluten-free cakes increased by 102%–534%, whereas ferric-reducing antioxidant power increased by 29.6%–143%. Up to 10% UBPF substitution resulted in texturally and sensorially acceptable, nutritious gluten-free cakes.

Practical implications

The developed product can be used practically for several applications as a healthy alternative. The use of unripe banana peel represents a promising strategy to increase the nutritional value and number of ready-to-eat food in the gluten-free market.

Social implications

This study propounds a nutritious, functional and sensorially acceptable gluten-free cake for celiac people to use practically while socialization. Cakes which are appreciated by panelists in sensory analysis will create product variety in kitchens, markets and social areas, in particular for those people suffering from celiac and gluten intolerance.

Originality/value

This is the first study to consider UBPF as an ingredient in gluten-free cake formulation. The product may positively contribute to the life quality of celiac people by propounding a gluten-free snack food for consumption in their social life. This study is also an example of the contribution of banana by-products toward the implementation of the circular economy.

Abstract

Purpose

The objective was to evaluate the effect of banana peel into cake (a bakery product that may add bananas) and panettone (a product that never is added to bananas) formulations on consumers' acceptance and perceived attributes and the effect on the technological properties of the product.

Design/methodology/approach

Bakery products were produced with banana peel in the formulation and control samples without residue. Volunteers scored their acceptance and checked all attributes applied to the four samples in the blind and informed tests. The texture, color, proximate composition and bake properties were measured.

Findings

The acceptance of both cakes, with and without banana peel, was not affected when consumers were informed that there was a residue in both cakes. Relative risk indicated that information had no influence on acceptance. Panettone with banana pulp showed a reduction in acceptance when volunteers were informed of the presence of banana peel. Risk analysis showed a significant relative risk of product rejection when consumers were aware of information. The addition of banana peel enhanced panettone chewiness and crumb hardness, reduced bake loss of cakes, reduced the volume of both products and changed some color parameters of both products.

Originality/value

Banana peel is a source of functional compounds, but it is not clear how consumers react when informed that the food presents it.

Abstract

Purpose

The purpose of this research is to develop an environmentally friendly antimicrobial dyeing of cotton fabric from the root of Euclea racemosa. Textile phytochemical finishing is in high demand worldwide because of its low toxicity, low pollution, ease of availability, renewability, pharmacological effects and non-carcinogenic properties, as well as its multifunctionality, rapid process stages and potential health benefit.

Design/methodology/approach

The cotton fabric was dyed with aqueous extracts of Euclea racemosa root dyes. Dyes were extracted for 20 min at pH 7.43 at room and boiling temperatures with material-to-liquor ratios (MLRs) of 1:5, 1:10, 1:15 and 1:20, altering one variable at a time, and the cotton fabric was colored using a post-mordanting procedure at 50°C with an MLR of 1:20. Using a properly cleaned Petri plate, the colored samples were tested in vitro for antibacterial activity. A spectrophotometer was used to assess color strength and shade depth, as well as wash fastness and annual rubbing fastness tests for both wet and dry.

Findings

L* = 36.29, a* = 58.56, b* = 32.46 and K/S = 0.51 were the CIELAB values for dye extracted at boiling temperature. L* = 47.14, a* = 42.23, b* = 49.61 and K/S = 0.38 were the CIELAB values for dye extracted at room temperature. The wash and rubbing fastness of the dyed samples were outstanding and the dyed cotton fabrics were found antibacterial against Gram-negative bacteria Escherichia coli.

Originality/value

Dyes derived from the E. racemosa root could be used to develop a new antibacterial cotton fabric dye.

Abstract

Purpose

The purpose of this article was to study the influence of oyster mushroom powder (Pleurotus ostreatus) as a partial substitute for sodium pyrophosphate in frankfurters made from red tilapia (Oreochromis spp.) fillets.

Design/methodology/approach

This study looks at adding oyster mushroom powder (OMP) to the emulsion at concentrations of 0, 0.075, 0.150, 0.225 and 0.300% (p/p) in combination with sodium pyrophosphate (PS), which was added at concentrations of 0.225, 0.150, 0.075 and 0%, respectively. A sausage with only sodium pyrophosphate added was evaluated as the control sample. The proximal chemical composition, physicochemical parameters, color, texture, lipid oxidation and sensory characteristics were determined for each treatment.

Findings

The results revealed that adding OMP up to 0.150% (w/w) provided the best conditions for the sausages in terms of pH, lipid oxidation, moisture retention capacity and cooking losses. In addition, the characteristics of texture and color, as well as the sensory evaluation, showed the best values for this OMP and SP ratio, meaning a substitution of sodium pyrophosphate with oyster mushroom powder at this concentration is suitable.

Originality/value

This paper discusses the beneficial properties of oyster mushroom powder, thereby showing potential for the establishment of health-promoting effects of the fish sausages.

Abstract

Purpose

People are increasingly concerned about food and health and are seeking enriched products. One way to add nutritional value to yogurt consists of the addition of nutritional flour. However, it is necessary to optimize formulations that meet the consumers’ expectations. Thus, the purpose of this paper is to aim at sensory optimization of a strawberry yogurt enriched with different flours.

Design/methodology/approach

The optimal concentrations of each flour were defined using the Just-about-right-scale test. Then, an acceptance test was used to assess the samples at optimal concentrations.

Findings

It was observed that the strawberry yogurt should include 1.275 percent golden flaxseed flour, 1.093 percent green banana flour, 1.075 percent eggplant flour and 3.420 percent oatmeal flour. All formulations had good acceptability and the yogurt added with the addition of golden flax flour and the traditional product received similar sensory acceptance. Thus, it is possible to add nutritional value to strawberry yogurt by maintaining its sensory quality.

Research limitations/implications

More detailed studies on the shelf-life of yogurt are necessary to enable the incorporation of flours into yogurt as heat, light and oxygen can reduce the beneficial effects of flours. Therefore, researchers should test the proposed propositions further.

Practical implications

Optimization of an enriched yogurt is a good alternative to provide a product that meets consumers’ expectations, besides adding value to the product. However, there are technological challenges when adding functional components in foods. Thus, this study aimed at sensory optimization of a strawberry yogurt enriched with different flours.

Social implications

The authors aimed to provide a healthy product to the market as well as contribute toward product variety in the market.

Originality/value

There are few studies in respect to the sensory aspects of enriched yogurts. Therefore, this work will aid future studies, supporting the optimization of functional products and contributing toward product variety in the market.

The purpose of this paper is to investigate the effect of partial substitution of wheat flour with sweet potato flour on the nutrient composition and sensory properties of bread.

Abstract

Purpose

The purpose of this paper is to investigate the effect of partial substitution of wheat flour with sweet potato flour on the nutrient composition and sensory properties of bread.

Design/methodology/approach

Sweet potato flour was blended with wheat flour at 5, 10, 15, 20 and 25 percent levels of substitution for bread production. Proximate, minerals and antinutritional factors of the breads were investigated using AOAC methods. Sensory evaluation was carried out by a panel of 50 consumers. Data were subjected to analysis of variance and means were separated by Tukey’s comparison test at p <0.05. Results were reported as mean ± SD.

Findings

The nutritional and sensory quality of bread made from wheat flour supplemented with sweet potato flour at 5, 10, 15, 20 and 25 percent was investigated. Blending of sweet potato flour with wheat flour had significantly decreased the protein content (4.76–7.78 percent) while the ash (1.35–3.07 percent), crude fiber (0.24–1.03), carbohydrate contents (88.39–90.45 percent), iron, zinc, phosphorus and vitamin A contents were significantly increased ( p<0.05) with increasing sweet potato flour in the formulations. The tannin and phytate contents of the composite breads were low. Sensory evaluation of the breads revealed a mild reduction of the bread’s general acceptability with increase in the substitution level by sweet potato flour.

Originality/value

This study showed that the wheat flour used in making breads could be substituted with up to 15 percent sweet potato flour without compromising its nutritional quality, with only a mild reduction in sensory quality.
