Abstract

The use of mangrove leaves as a functional ingredient is associated with secondary metabolites such as steroids, saponins, tannins, phenols, flavonoids, antioxidants, magnesium, sodium, potassium and calcium. This research determined the total phenol content (TPC), total flavonoid content (TFC) and antioxidants (IC50) in dry and fresh mangrove leaf infusion extracts. The method used was infusion extraction. The materials used are fresh mangrove leaves and dried leaves (dried in the oven). The data obtained then discussed descriptively based on the average obtained in the calculations. The research results showed that the type or condition of leaves used has an influence on TPC, TFC and Antioxidants (IC50). Oven drying can produce higher levels of secondary metabolites compared to fresh leaf infusion (TPC, 36 mg GAE/g; TFC 4.12 mg QE/g; IC50 225,706 ppm). Dried leaf extraction has better potential in producing secondary metabolic compounds and antioxidants. The choice of extraction method and type of solvent is highly recommended for further research objectives, because it suits research interests. It is recommended that when making functional drinks (tea) from mangrove leaves, to add other sources of ingredients such as dried lemon or mint leaves so that the resulting flavor is fresher and provides a better linking assessment of preferences.

Abstract

Yogurt is a fermented product that is popular and easily accepted by the public because of its benefits and good nutrition. However, the presence of lactose intolerance disorder caused by milk is an obstacle to getting the benefits of yogurt, so it is necessary to develop by using low-lactose milk in yogurt drink products . This research is an experimental study that aims to compare the nutritional content and sensory value of yogurt drink based on whole milk and low-lactose milk with the addition of L. Plantarum Dad 13. pH test, proximate analysis and sensory analysis of yogurt drink were carried out. The results showed that fresh milk yogurt drink samples had a lower final pH compared to samples using low lactose milk (p>0.05). Meanwhile, the low lactose yogurt had a lower sugar content compared to whole milk-based yogurt (p>0.05). Although the content analysis showed insignificant results, yogurt drink with the addition of L. plantarum Dad-13 showed good nutritional content compared to whole milk yogurt. Sensory test showed that probiotic yogurt drink tended to be preferred due to its flavor and higher acceptance level compared to whole milk yogurt.

Abstract

Nitrite is a common food additive used to enhance the safety and shelf life of processed meat products. However, recent concerns have emerged regarding its potential link to colorectal cancer in humans. Despite this, the effectiveness of different cooking methods in removing nitrite from processed meats remains unclear. This study aimed to identify cooking methods that effectively reduce nitrite content in ham. Three cooking methods—boiling, pan-frying, and microwave heating—were evaluated. Nitrite content in ham was measured using the diazotization-coupling reaction. The results showed that boiling significantly reduced the nitrite content in ham compared to the uncooked state. In contrast, pan-frying and microwave heating had no significant effect. Long-term storage also reduced nitrite levels, and combining storage with boiling had a synergistic effect in further reducing nitrite content. Additionally, soaking ham in condiments prior to cooking was found to be effective in lowering nitrite levels. Notably, soaking in grain vinegar resulted in a substantial reduction. Overall, the study demonstrated that boiling is an effective method for reducing nitrite content in ham. Furthermore, extended storage and pre-soaking in condiments, particularly grain vinegar, also contributed to nitrite reduction.

Abstract

This study aims to determine the effect of pretreatment, temperature, and drying time on the organoleptic properties of tempeh gembus flour. Tempe gembus is a fermented product derived from tofu waste with high protein content, but it has limitations in terms of shelf life and sensory characteristics that are difficult to accept in society. This study employed an experimental design with variations in pre-treatment (steaming and roasting), drying temperature (70°C and 80°C), and drying time (5 and 6 hours). Trained panelists conducted sensory evaluations to assess the color, aroma, taste, texture, and appearance of the resulting flour. Based on the sensory evaluation, the best tempe gembus flour was produced with a pre-treatment of 15 minutes of steaming, dried at 80°C for 5 hours. Chemical analysis of the best sample revealed a composition of 42.15% carbohydrates, 33.56% protein, 5% fat, 11.95% moisture, 0.31% ash, and 6.87% fiber.

Abstract

Rubber seeds (Hevea brasiliensis) have great potential as an alternative food source, particularly as a substitute ingredient in tempe production, due to their high protein and oil content. However, the presence of toxic hydrocyanic acid (HCN) remains a major obstacle to their utilization. This study aimed to investigate the effectiveness of soaking and heating processes in reducing HCN content and their effects on the nutritional composition of rubber seeds. A quantitative descriptive method with a Completely Randomized Design (CRD) was employed. The soaking treatment was applied for 0, 12, 24, and 36 hours, followed by two heating methods, namely steaming and boiling, each conducted for 30, 60, 90, and 120 minutes with three replications. HCN content was analyzed using spectrophotometry, with data processed using ANOVA and further tested with DMRT at a 5% significance level, while proximate analyses were analyzed descriptively. The results indicated that 24-hour soaking effectively reduced HCN levels to 0.14%, while heating for 120 minutes via steaming and boiling reduced HCN levels to 15.98 ppm and 14.21 ppm, respectively, below the safe consumption limit of 20 ppm. Proximate analysis showed no significant changes in the main nutritional components, although a slight decrease in fat and protein content was observed with longer heating durations. The study concluded that the combination of soaking and heating effectively reduced cyanide levels in rubber seeds without causing significant nutrient loss. Further research is recommended to explore fermentation processes, sensory characteristics, and food safety aspects of tempe made from rubber seeds as a local food diversification effort.

Abstract

COVID-19 has placed a substantial burden on global healthcare systems. Nutritional improvement through dietary supplementation with vitamin C, vitamin D, and zinc plays a critical role in supporting the immune system. This study aimed to evaluate the effect of combined supplementation with vitamins C, D, and zinc on the length of hospital stay in COVID-19 patients. This study employed a retrospective observational design conducted in a hospital setting. A total of 81 patient were included as research subjects. The majority of patients were aged 50–64 years (45.7%) and female (51.9%). Data were analyzed using the Kruskal–Wallis test, followed by post hoc analysis. The results showed that the group receiving the combined supplementation of vitamins C, D, and zinc had the shortest average hospital stay (10.00 ± 4.299 days), compared to the vitamin D group (12.29 ± 4.165 days) and the vitamin C and D group (12.69 ± 2.869 days), with a statistically significant difference (95% CI; p = 0.004). This study concludes that the combination of the three micronutrients (vitamins C, D, and zinc) significantly reduces the duration of hospitalization in COVID-19 patients compared to those receiving vitamin D alone or a combination of vitamins C and D.
