Abstract

Commercially sold white bread is often enriched with cow's milk in its formulation, which is often avoided by vegetarians. Hence the need for alternative bread products that use plant-based ingredients. Alternatives to cow's milk, namely plant-based milks, have gained popularity due to their various health benefits. Milk made from nuts has been identified as a suitable alternative for individuals allergic to cow's milk or those seeking plant-based options due to lifestyle. Therefore, this study aimed to utilize nut milk in the manufacture of white bread in terms of its physicochemical characteristics. The research method consists of four steps, namely making nut milk, making white bread, physicochemical analysis, and statistical analysis. In this study, bread texture was tested with the parameters of hardness, cohesiveness, springiness, gumminess, chewiness, fracture force, adhesive force, adhesiveness and stiffness. However, after statistical analysis using ANOVA (Analysis of Variance) on these parameters, there was parameter that did not have significant differences, namely the fracture force parameter. While in the proximate analysis, all parameters (carbohydrate, protein, fat, water, and ash) had significant differences after statistical analysis using ANOVA. It can be concluded that milk made from legumes can be utilized as an alternative to cow's milk in making bread.

Abstract

Introduction: Gluten-free bread is a type of bread product made without gluten, and its consumption has increased in recent years, especially for individuals with celiac disease or driven by health considerations. The absence of gluten in gluten-free bread presents challenges in achieving the desired texture and structure. The incorporation of psyllium husk and chia seed into gluten-free bread formulations offers numerous benefits, both in terms of improving the bread's physical properties. Therefore, this study aims to find gluten-free bread formulations from a mixture of psyllium husk and chia seed seen from physical and sensory characteristics. Methods: This research method consists of the making of gluten-free bread, physical analysis (texture), sensory analysis, and statistical analysis. Results: For physical characteristics, psyllium husk, and chia seed incorporation affect springiness index, chewiness, adhesive force, and adhesiveness parameters in gluten-free bread, while for sensory characteristics several parameters have significant differences, namely aroma, taste, texture, and overall parameter, meanwhile appearance parameter has no significant difference. For the overall parameter, gluten-free bread with only psyllium husk (Formulation 1) received the highest rating preferred by the panelist. Conclusion: The incorporation of psyllium husk and chia seed affects the physical and sensory characteristics of gluten-free bread.

Abstract

Introduction: Green banana flour (GBF), rich in resistant starch and dietary fiber, has gained attention as a functional ingredient for improving gut health and metabolic regulation. While GBF has been applied in conventional bread, its effect on sourdough bread remains underexplored. This study aimed to evaluate the physical and sensory properties of sourdough bread incorporated with GBF. Methods: Sourdough bread was prepared using wheat flour (control, TC) and GBF substitution at 10% (TP1), 20% (TP2), and 30% (TP3), with identical hydration and processing conditions. Texture profile analysis was performed using a texture analyzer, while sensory evaluation was conducted with 50 untrained panellists using a 5-point hedonic scale. Data were analyzed by ANOVA followed by Duncan’s test (α = 5%). Results: Texture analysis revealed that increasing GBF substitution significantly elevated hardness, springiness, and stiffness, while reducing fracture force compared to TC. Sensory results indicated that TC scored the highest in all parameters, especially taste (4.20 ± 0.67) and overall acceptability (4.26 ± 0.76). TP1 remained acceptable, showing comparable scores to TC in aroma (3.68 ± 0.74) and texture (3.84 ± 0.57). However, TP2 and TP3 demonstrated lower consumer acceptance, with TP3 recording the lowest scores in taste (3.14 ± 0.78) and overall acceptability (3.36 ± 0.88). Conclusion: GBF incorporation modifies sourdough bread texture by increasing firmness and structural density, while sensory acceptance declines at higher substitution levels. Up to 10% GBF can be added without compromising consumer preference, offering potential for developing nutritionally enhanced sourdough bread.

Abstract

Sourdough bread is increasingly recognized not only for its nutritional benefits but also for its potential to incorporate local ingredients that improve sensory and functional qualities. Dangke (Enrekang cheese), a traditional Indonesian dairy product, contains protein and lipid components that may influence the texture and flavor profile of sourdough bread. This study aimed to evaluate the effect of Dangke incorporation on the physical and sensory characteristics of sourdough bread, with a focus on identifying the optimal concentration that enhances bread quality. Texture analysis was performed using a texture analyzer to measure hardness, cohesiveness, springiness, gumminess, chewiness, fracture force, adhesiveness, adhesive force, and stiffness and sensory analysis was conducted to assess visual, taste, aroma, texture, and overall acceptance. Statistical analysis was conducted using ANOVA and Duncan’s test. Significant differences were observed in hardness, fracture force, and stiffness, while other parameters showed no statistical differences. Moderate incorporation of Dangke (10–20%) reduced hardness and stiffness, producing softer crumb structures. However, at higher concentrations (30%), hardness and stiffness increased, likely due to competition for water absorption and disruption of gluten networks. Sensory results showed improved flavor, aroma, and overall acceptance with increasing Dangke levels, with the highest scores obtained at 20–30%. Incorporating Dangke at optimal levels (20–30%) significantly improves the sensory quality of sourdough bread while maintaining desirable texture. These findings highlight the potential of Dangke as a functional ingredient for product diversification and nutritional enrichment in sourdough-based bakery products.

Abstract

Introduction: Sourdough bread has gained popularity due to its nutritional and sensory benefits, with lactic acid bacteria fermentation improving digestibility, glycemic response, and bioactive compound availability. The incorporation of nutrient-dense superfood leaf flours such as Moringa oleifera, Sauropus androgynus, and Centella asiatica may further enhance its functional properties. Methods: Sourdough bread was formulated with wheat flour partially substituted by superfood leaf flours at 5%, 10%, and 15% levels. Physical properties were analyzed using a Texture Analyzer (hardness, cohesiveness, springiness, chewiness, stiffness, etc.), while sensory acceptability (appearance, aroma, taste, texture, and overall preference) was evaluated by 50 untrained panelists. Data were statistically analyzed using ANOVA and Duncan’s Multiple Range Test (α = 5%). Results: Textural analysis showed significant differences across treatments, particularly in hardness, cohesiveness, springiness, chewiness, and stiffness. Higher substitution levels of leaf flour generally increased crumb hardness and chewiness due to reduced gluten structure. Sensory analysis indicated that the control bread (100% wheat flour) received the highest overall rating. Among the modified breads, the 5% Centella asiatica formulation (TP1) was the most preferred, likely because moderate substitution imparted a mild herbal flavor and retained a soft crumb structure, while higher levels reduced sensory acceptability. Conclusion: The incorporation of superfood leaf flours significantly influenced both physical and sensory characteristics of sourdough bread. While control bread was most preferred, 5% Centella asiatica substitution emerged as the optimal formulation among the enriched variants, balancing improved nutritional potential with favorable consumer acceptance.

Abstract

Vegetable consumption in Indonesia is low, particularly among preschool-aged children, who often do not meet daily intake recommendations. Sensory factors, such as taste, texture, and appearance, strongly influence children’s acceptance of vegetables. Previous studies have shown that modifying vegetables and using play-based learning can improve children’s interest. This study aimed to develop an edible folding paper made from vegetables, serving as both a nutritious food product and an interactive learning tool. Spinach, purple cabbage, and pumpkin were chosen for their good acceptance, nutrient content, and color appeal. The product was analyzed for macronutrients (proximate analysis) and micronutrients, including vitamin C, antioxidant activity, and iron (Fe) content. The results showed adequate levels of energy, protein, fat, and carbohydrates. Micronutrient analysis indicated 3.31 mg of iron, 53 mg of vitamin C, and 56.21% antioxidant inhibition per 100 g of product. Texture evaluation using origami-style folding confirmed good flexibility and tear resistance, supporting its function as an edible paper. Overall, the product retained substantial nutrients and could be folded into origami shapes without losing its structural integrity. This innovation has the potential to increase vegetable intake in children and improve dietary quality during early childhood.

Abstract

This study investigated the effect of beetroot powder incorporation on the physicochemical, textural, and sensory properties of sourdough bread as part of efforts to develop nutritionally enhanced bakery products with acceptable quality. Four formulations of composite flour of 300 g were prepared: a control (without beetroot powder) and sourdough breads substituion of beetroot powder of 5, 10, and 15%. The physicochemical and textural characteristics were evaluated using texture profile analysis, including hardness, cohesiveness, gumminess, chewiness, adhesiveness, stiffness, and springiness, while sensory attributes were assessed based on appearance, aroma, taste, texture, and overall acceptability. The results demonstrated that increasing beetroot powder levels significantly affected most textural parameters. The highest values of hardness (254.79 gf), gumminess (57.75), and chewiness (4.51) were observed in bread with substitutuion with beetroot powder of 15%, indicating a denser crumb structure at 15% substitution level. Cohesiveness and stiffness increased with beetroot addition, whereas springiness generally decreased, suggesting a trade-off between structural rigidity and elasticity of the dough. Sensory evaluation revealed that the control bread achieved higher scores across most attributes; however, the bread with beetroot powder substitution of 10% recorded the highest overall acceptability among the beetroot-enriched breads (3.90 ± 0.84). Moderate beetroot incorporation enhanced the visual appeal and flavor balance without masking the characteristic of the sourdough. However, excessive beetroot substitution negatively affected sensory quality due to the dominant earthy flavor and less desirable texture. In conclusion, 10% beetroot powder substitution provides an optimal balance between nutritional enhancement, textural quality, and consumer acceptance, offering valuable insights for the formulation of functional sourdough bread products.

Abstract

Red betel leaf (Piper crocatum) is a plant growing in tropical areas and previously known as an ornamental plant, but then later used as medicinal plant. Previous researches found that red betel leaves contain bioactive compounds such as alkaloids, flavonoids, tannins, and many more that have potential to be used as antioxidant. The extractions were carried out using variations of solvent types (ethanol, water, and ethyl acetate) and feed to solvent (F:S) ratios in g/ml (F:S=1:20, F:S=1:25, F:S=1:30). The best conditions from this research were the usage of ethanol as the solvent. In addition to its ability to extract the compounds potential as antioxidant and F:S ratio of 1:30, it could give highest yield of extract. Variation of solvent type and variation of F:S have significant effect on the value of antioxidant activity (IC50) of the red betel leaf sample.

Abstract

Edible flower adalah jenis bunga yang aman untuk dikonsumsi. Edible flower kaya akan senyawa bioaktif seperti asam fenolik, karotenoid, dan flavonoid. Penelitian ini bertujuan untuk mengeksplorasi dua jenis edible flower, yaitu Nasturtium (Tropaeolum majus) dan Torenia (Torenia fournieri) guna pengembangannya sebagai produk teh celup. Teh celup bunga Rosella yang sudah dikenal luas digunakan sebagai produk pembanding. Pengolahan teh celup terdiri dari beberapa tahapan yaitu persiapan dan pengeringan edible flower dan proses penyeduhannya. Seduhan teh edible flower kemudian dianalisis total flavonoid, aktivitas antioksidan, dan sifat sensorisnya. Hasil penelitian menunjukkan bahwa seduhan teh celup bunga Torenia  mempunyai total fenol dan aktivitas antioksidan paling tinggi, yaitu 58,04 mg QE/g ekstrak dan IC50 9,18 mg/L, disusul oleh seduhan teh celup bunga Nasturtium (45,12 mg WE/g ekstrak dan 11,62 mg/L) dan teh celup bunga Rosella (19,55 mg QE/g ekstrak dan 19,77 mg/L). Seduhan teh bunga Torenia mendapatkan respons sensoris hedonik yang setara dengan seduhan teh bunga Rosella untuk atribut warna, aroma dan rasa, yaitu disukai, tetapi lebih baik untuk atribut keseluruhan (disukai dibanding agak disukai). Sedangkan teh bunga Nasturtium mendapatkan respons sensoris hedonik lebih rendah dari keduanya. Diantara dua teh edible flower yang diuji, teh bunga Torenia lebih berpotensi untuk dikembangkan menjadi teh herbal karena mempunyai respons sensoris setara dengan teh bunga Rosella tetapi mempunyai aktivitas antioksidan yang lebih tinggi.
