2024-08-24T22:29:55+07:00

The purpose of this study is to ascertain the optimal concentration and the impact of adding durian seed flour to the ice cream's physical, chemical, and sensory characteristics. This investigation was carried out experimentally with three replications and six treatments using a totally randomized methodology. UD1 (control), UD2 (with 0.2% durian seed flour added), UD3 (with 0.4% durian seed flour added), UD4 (with 0.6% durian seed flour added), UD5 (with 0.8% durian seed flour added), and UD6 (with 1.0% durian seed flour added) was the treatments that were employed. Descriptive and hedonic sensory evaluations of softness, total solids, protein content, and melting speed were all significantly impacted (P<0.05) by variations in durian seed flour in terms of lowering overrun. The selected treatment in this study was treatment UD3 (addition of 0.4% durian seed flour) with overrun of 31.85%, melting speed of 20.29 minutes, total solids of 42.95%, protein of 5.82%, and fat of 7.85% with characteristic light purple color, not smelled of durian seed flour, not taste of durian seed flour, very soft texture, and overall the panelists liked it.

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.

Substitution of wheat flour with purple sweet potato and red bean increased energy value, protein, and fat content of muffin

2024-10-26T14:20:38+07:00

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.

Formulation and physical characteristics of ready-to-drink chocolate beverages with the addition of xanthan gum

2025-03-06T10:59:51+07:00

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.

Phytochemicals, nutritional, anti-nutritional and bioactivity of Dioscorea pentaphylla L. tuber : A review

2024-10-27T13:40:39+07:00

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.
