Abstract

Aloe vera gel contains antioxidative phenolic compounds. Fresh aloe vera gel is less accepted by the community due to its bitter taste from its latex. An acceptable alternative to aloe vera products is an aloe vera gel beverage because people of all ages currently favor light drinks. This study aims to produce aloe vera gel beverages with high antioxidant content by varying the gel size and boiling duration for easy consumption and preference by panelists. This research employed a completely randomized design (CRD) with two treatment factors, namely variations in gel size (0.5x1 cm, 1x2 cm, 2x3 cm) and boiling duration (10 minutes, 15 minutes, 20 minutes). The obtained data were subsequently analyzed Analysis of Variance (ANOVA). If differences were found, Duncan's Multiple Range Test (DMRT) was conducted at a significance level of 5%. The research results indicate that variations in gel size and boiling duration affect antioxidant activity, moisture content, total sugar content, gel texture, and preference level. The acceptable aloe vera gel beverage, preferred by the panelists which made with a gel size of 0.5x1 cm and a boiling duration of 10 minutes, with exhibited the highest antioxidant activity 6.72% RSA, moisture content 94.15%, total sugar content 13.35%, hardness (6.25 g/cm2, and deformation 2.81 mm.

Abstract

Muffin is a wheat flour-based snack with gluten content and high glycemic index, so substitution is needed to reduce the impact of excess consumption on health. The ingredients used are purple sweet potato and red bean which have high content of energy, carbohydrates, protein and low GI. The study aimed to determine the effect of substituting wheat flour with sweet potato flour and red bean flour on the nutritional value of muffins. This was an experimental study with a single-factor completely randomized design (CRD) with one control group and three treatment groups with the proportion of wheat flour: purple sweet potato flour: red bean flour namely 100:0:0 (P0), 30:20:50 (P1), 30:35:35 (P2), dan 30:50:20 (P3). They were repeated 3 times.  The results showed that there was an effect of wheat flour substitution with sweet potato flour and red bean flour on the nutritional value of muffins (p<0.001). The highest average nutritional value of each treatment is water content P3 (34.45%), ash content P3 (3.06%), protein P1 (9.92%), fat P1 (9.39%), carbohydrate P3 (44.67%), and energy P1 (294.23 kcal). The nutritional value of 50g muffins is in accordance with the quality standards according to SNI and the standard requirements for children, but the fat content is above the standard if it is consumed as snacks for DM patients, therefore it needs to reformulate to fulfill the standard.

Abstract

Dioscorea pentaphylla L. tubers, locally known as tomboreso tubers by Indonesian people, grow wild in forests in various parts of Indonesia but are not well-underutilized. This article aims to comprehensively review the phytochemistry, nutritional, anti-nutritional, and bioactivity of tomboreso tubers. The method used is a literature study with a database of online articles downloaded from Google Scholar related to the topic discussed. Various earlier studies reported that tomboreso tubers are rich in phytochemical compounds, such as alkaloids, flavonoids, polyphenols, terpenoids, tannins, glycosides, and saponins. Tomboreso tubers are also rich in complete nutritional content, such as protein content (1.69-9.20%), fat (0.14-6.24%), fiber (1.28-7.24%), starch (3.71-61.26%), minerals, amino acids, and fatty acids. Furthermore, tomboreso tubers also contain anti-nutritional compounds that are less beneficial to health, such as tannins, oxalates, hydrogen cyanide, phenols, flavonoids, phytates, a-amylase inhibitors, and trypsin inhibitors. Tomboreso tubers have been shown to have various biological activities, such as anti-bacterial, anti-mutagenic, and antioxidant, from various earlier studies. To make tomboreso tubers safe to eat and an alternative food source with low anti-nutritional content, further research must be done on their exploration, utilization, and further processing to reduce anti-nutritional compounds.

Abstract

Purple yam is one of the tubers that serves as a source of antioxidants but has not been optimally utilized. Therefore, it needs to be diversified by processing it into snack bars. This study aims to develop snack bars made from purple yam flour, sorghum flour, and mung bean flour, which have the potential to serve as antioxidant sources and are preferred by panelists. In this study, snack bars were prepared using composite flour (sorghum:mung bean) and purple yam flour in varying ratios: 95:5, 90:10, 85:15 for the composite flour and 20%, 30%, and 40% for the purple yam flour. The snack bars were evaluated for color, texture, moisture content, antioxidant activity, and preference level. Selected samples were further analyzed for ash content, protein content, fat content, anthocyanin content, and crude fiber content. The experimental design used was a Completely Randomized Design (CRD) with two factors. The snack bars with a composite flour ratio (sorghum:mung bean) of 85:15 and 30% purple yam flour were identified as the best treatment, preferred by panelists and exhibite high antioxidant activity. These snack bars had a moisture content of 13.40%, ash content of 8.83% (db), protein content of 19.75% (db), fat content of 8.80% (db), crude fiber content of 9.54% (db), antioxidant activity of 68.02% (RSA), and anthocyanin content of 37.40 mg/100g

Abstract

Chitosan is a natural polysaccharide derived from chitin, commonly found in the shells of crustacean animals. The production of chitosan involves several stages: deproteinization, demineralization, and deacetylation, which require the use of acidic and alkaline solutions. This study aimed to evaluate the effectiveness of various types of organic acids and a natural acid source, Averrhoa bilimbi (bilimbi fruit) extract, in the chitosan extraction process from Vannamei shrimp shells. The study employed a completely randomized design with a single factor consisting of four acid treatments: acetic acid (AA), citric acid (CA), lactic acid (LA), and bilimbi fruit extract (BE), each replicated three times. The chitosan obtained from each treatment was analyzed for its chemical characteristics and mineral content, and the results were further analyzed using Principal Component Analysis (PCA). The best results were obtained from the citric acid treatment, which produced chitosan with a moisture content of 6.59%, a degree of deacetylation of 91.72%, ash content of 2.68%, and magnesium and calcium contents of 2.56 mg/100g and 0.15 mg/100g (dry basis), respectively. In contrast, the bilimbi extract treatment resulted in an ash content of 41.64%, with magnesium and calcium contents of 1456.52 mg/100g and 4.17 mg/100g (dry basis), indicating that the bilimbi fruit extract still has low demineralization effectiveness.

Abstract

Ready-to-drink (RTD) chocolate beverages are increasingly popular, yet traditional formulations often contain dairy components while some consumers are lactose intolerance. The primary challenges in RTD chocolate beverages include achieving acceptable flavor profiles and managing cocoa powder precipitation. This study aimed to formulate a non-dairy ready-to-drink chocolate beverage using a hedonic test and  enhance its physical stability through varied xanthan gum concentrations applying Completely Randomized Design (CRD).A hedonic test involving 30 untrained respondents determined the most preferred formula with the highest preference level (3.7), which consisted of 40% local cocoa powder from Kulon Progo, Yogyakarta, 15% commercial cocoa powder, and 45% castor sugar. Stability analysis involved incorporating xanthan gum at concentrations of 0.1%, 0.15%, and 0.2% (w/v). Results demonstrated that 0.2% xanthan gum concentration yielded the highest viscosity (98 N.s/m²), significantly differing from the control. The lowest precipitation was observed at 0.2% concentration (p-value 0.048). Particle size analysis revealed progressive reduction from 21 μm to 5 μm with increasing xanthan gum concentration. The study conclusively identified 0.2% (w/v) xanthan gum as the most effective concentration for improving chocolate beverage stability, offering a promising approach for developing innovative, dairy-free RTD products.
