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.

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.

Indonesia has variety of fruits that have the potential to be used as botanical water in sourdough bread making, especially those with high sugar content. Salak pondoh (Salacca zalacca var pondoh) is one of Indonesia's native fruits that has a distinctive flavor and is favored by the public. This research aims to utilize botanical water from salak pondoh in the making of sourdough bread. This research method consists of several stages, namely making botanical water, making starter, evaluating yeast activity, and white bread production. The analysis performed on white bread includes physical analysis, chemical analysis, and sensory analysis. Yeast activity in this study showed that the use of sourdough starter with the percentage of 30% had the highest activity level of 1.035 ± 0.002 ml/hour. Proximate test results showed significant differences in protein content, water content, and fiber content, while carbohydrate, fat, and ash content were not significantly different. The results of the texture test showed significant differences for hardness and springiness parameters, while for other texture parameters there were no significant differences. Overall, white bread using sourdough starter from salak pondoh can develop well and can be accepted like white bread in general, even in this study white bread with the addition of sourdough starter obtained a higher hedonic rating compared to white bread sample control.

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.

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.

Purple sweet potato and Cilembu sweet potato offer unique advantages when added to bread dough formulations. Purple sweet potato, known for its rich nutritional profile and vibrant colour, while Cilembu sweet potato is known for its sweetness. Both purple sweet potato and Cilembu sweet potato offer opportunities to diversify bread formulations, especially with a number of health benefits on offer. By utilizing these two sweet potatoes by adding them to a previously researched sourdough bread dough, this study aimed to examine the physical characteristics of the final sourdough bread. The research method consisted of selecting and processing sweet potatoes for bread formulation, making sweet potato sourdough bread, physical analysis namely colour and texture and statistical analysis. The results showed that the addition of sweet potato, both purple and Cilembu, caused significant differences in all colour parameters, namely parameters L, a and b of the bread. In texture characteristics, the addition of Cilembu sweet potato caused significant differences in stiffness parameters while purple sweet potato caused significant differences in hardness, springiness and springiness index parameters. The addition of purple sweet potato and Cilembu yam to white bread affects the physical characteristics especially in colour and texture.
