Abstract

Self-rising starch is a development product of self-rising flour. This product  minimizes the process, especially in the salt and leavening agent weighing stage, so that it reduces the time in the serving process.  Self-rising flour is generally made of wheat flour.  Currently, due to some medical considerations, many people cannot consume this product. Based on some research results, gluten compound in wheat flour or wheat triggers for the development of type-1 diabetes. This fact has caused Indonesia to be ranked fifth in the world for the diabetic diseases. Thus, one of the ways to overcome this problem is by utilizing the raw materials originating from Indonesia too, namely tubers. Indonesia has a variety of tubers. Some of these tubers, however, have not been explored. These tubers have not only the function as the good sources of carbohydrates but also the bioactive compounds and more functional values, such as water soluble polysaccharides (WSP), diosgenin, inulin and glycemic index. They increase the functional properties of the starch that are produced. The tubers that currently have not been cultivated are the genus Dioscorea. The various tubers that are included in dioscorea family are uwi, gembili, gadung, tomberoso and jebubuk. All of these tubers are good sources of carbohydrates. Uwi, gembili and gadung are tubers that have been cultivated by the people for many years. On the hand, tomberoso and jebubuk tubers grow wildly in the forest that only become the foods for the wild animals in it. The starch derived from the disccorea tubers can be used as self-rising starch because it has the property as food developer. It contains high carbohydrates and bio-active compound, therefore, it is healthier to consume.

Abstract

Color is the main attraction in choosing food; therefore, manufacturers do various ways to produce good colors without considering the consumer's health. Natural colors are a safe choice for health; besides being safe, natural dyes can also provide functional properties to those who consume them. The study aimed to determine the activity of natural dyes and their functional properties when mixed with chemically modified arrowroot starch. This study used a factorial design with chemical modification factor A and factor B, a ratio of dragon fruit extract to the amount of starch, with three repetitions. The best treatment was A2B3 (cross-link, starch with dragon fruit 1:2) because it had the treatment with the most visible color. This treatment has an antioxidant content of 38.95%, a polyphenol content of 106.19 mg GAE/g, a color of 76.88, and an anthocyanin content of 0.71 mg/100g.

Abstract

Gambier (Uncaria gambir Roxb.) contains potent bioactive compounds with strong natural antimicrobial properties, making it a promising ingredient for acne treatment. However, its application in topical formulations remains limited due to a lack of understanding regarding the impact of processing conditions, particularly heating, on its functional efficacy. This study investigated the effect of heating duration on the characteristics of an acne treatment balm formulated with black cube gambier. Experiments using a completely randomized design (CRD) were carried out for 0, 30, 60, 90, and 120 minutes of heating durations to evaluate the balm's physical, chemical, and microbial properties. The results demonstrate that heating duration significantly influenced key parameters, including homogeneity, spreadability, melting point, irritation potential, texture, color, pH, total phenol content, and antibacterial activity (p < 0.05). The most optimal results were obtained at 120 minutes, yielding a balm with superior homogeneity, spreadability (4.47 cm), melting point (50°C), pH (7.44), total phenol content (54.28%), and diameter of the inhibition zone (16.35 mm). FTIR analysis confirmed an increase in phenolic compound stability, indicating enhanced antibacterial potential. These findings suggest that extended heating duration improves the stability and performance of gambier-based formulations. The optimized acne balm formulation highlights the potential of locally sourced gambier as a natural, eco-friendly acne treatment. Further research is recommended to evaluate product shelf-life, consumer acceptability, and industrial scalability.
