Abstract

Noodle products are classified as low-nutrient noodles because they have a high carbohydrate content but low protein, vitamins and minerals. Marine fish such as tuna and mackerel are food ingredients with high protein content, and they are abundant in Indonesia. The purpose of this study was to partially substitute wheat flour with tuna flour and mackerel flour and analyze the physical (rehydration power, cooking loss, elasticity power) and chemical (protein) characteristics of the resulting wet noodles. The data obtained were analyzed statistically using a simple group randomized design and repeated 3 times. The results showed that the physical and chemical characteristics of wet noodles with the addition of mackerel flour had a cooking loss value of 11.51-16.42%, elasticity value of 29.82-17.12 gf, rehydration power of 177.33-140.65%, and protein 11.25-15.24% db. The addition of tuna fishmeal to wet noodles has a cooking loss value of 15.11-20.03%, elasticity value of 30.12-19.22 gf, rehydration power of 183.15-160.72%, and protein 13.37-21.72% db. The addition of mackerel flour and tuna flour to wet noodle products increased protein content while affecting the product's physical properties. It is hoped that this research can provide comparative insights into the utilization of marine resources as fortification ingredients in noodle products.

Abstract

Yogurt is a fermented milk product known as a functional food. Food diversification efforts by finding alternative yogurt raw materials to replace animal milk are necessary to provide products for people who want alternative non-dairy yogurt products. One of the plant-based milks that has a nutritional content similar to animal milk is coconut (Cocos nucifera). Moringa leaves (Moringa oleifera) are reported to contain antioxidant compounds and have therapeutic benefits, making them potentially suitable for use as a fortifier in cocoyogurt functional drinks. The purpose of this study was to obtain the most appropriate formula for adding moringa leaf extract to produce cocoyogurt products that are high in antioxidants and have physicochemical and organoleptic properties that are acceptable to consumers. The design used in this study was a completely randomized design (CRD) with 4 treatments, namely: P0 = without the addition of moringa leaf extract; P1 = moringa leaf extract 1 g/L; P2 = moringa leaf extract 2 g/L; and P3 = moringa leaf extract 3 g/L. The data obtained were analyzed using the Analysis of Variance (ANOVA) statistical method and continued with Duncan's Multiple Range Test if there was a significant difference (P ≤ 0.05) between treatments. Based on the results of the study, it is known that the addition of moringa leaf extract to coconut milk yogurt produces cocoyoghurt with a low acidity (pH) (4.5-44.3), which is in accordance with the SNI standard (2981-2009) for yogurt quality. Overall, the best treatment in cocoyoghurt was the addition of 3 g/L of moringa leaf extract with an IC50 value of 148.33 µg/ml, with free radical inhibitory activity in the moderate category, and the sensory properties of taste, aroma, color, and texture showed the most preferred values ​​by the panellists. These findings have broader implications for functional food innovation, particularly in developing plant-based, nutrient-enriched products that cater to lactose-intolerant populations and health-conscious consumers seeking natural sources of antioxidants.

Abstract

Increased awareness of healthy lifestyles has spurred the growth of functional food trends among communities. Iron deficiency causes anemia, a major nutritional problem in Indonesia. Mangrove crab shells are a local source of iron. In most cases, the edible portion of crabs is limited to the meat, while the shells are discarded, leading to their high potential as a source of waste. The purpose of this study was to determine the effect of adding mangrove crab shell powder on the iron content of cookies. This study employed an experimental design using a Complete Randomized Design (CRD), with treatments of adding different concentrations of mangrove crab shell powder (0%, 3%, 6%, 9%, 12%, 15%). The data were analyzed using ANOVA and Duncan’s multiple range test. Findings indicated that adding mangrove crab shell powder significantly affected the iron content of the cookies. The iron content of the modified cookies ranged from 64.13 to 187.54 mg. The higher the concentration of crab shell flour added, the higher the iron content of the cookies. It is recommended that further research be conducted, encompassing organoleptic evaluation, microbiological contamination analysis, and heavy metal contamination assessment, to ensure the product's safety and quality. It is hoped that this research can serve as a reference on the use of crab shell waste as a source of iron that is beneficial to health.

Abstract

Oxidative stress, which arises from an imbalance between free radicals and the body’s antioxidant defences, is a major factor in the development of degenerative diseases, making the search for natural antioxidants an important area of research. Black goji berry (Lycium ruthenicum) is known to be rich in anthocyanins and polyphenols, while Chinese jujube (Ziziphus jujuba) contains high levels of vitamin C, flavonoids, and polysaccharides; both have been traditionally used in herbal medicine and are considered promising natural antioxidants. This research is the first study that examines the synergistic antioxidant effect of black goji berry and Chinese jujube. An experimental laboratory study was conducted with five treatment groups consisting of Chinese jujube (100%); black goji berry (100%); black goji berry 75% : Chinese jujube 25%; black goji berry 25% : Chinese jujube 75%; and black goji berry 50% : Chinese jujube 50%. Infusion samples were analyzed for antioxidant activity, and data were further analyzed statistically using one-way ANOVA followed by Tukey’s post hoc test. The results demonstrated significant differences in antioxidant activity among treatments (p < 0.05). Chinese jujube exhibited the weakest activity with an IC50 value of 35,695.24 ppm, while the 50:50 combination of black goji berry and Chinese jujube showed the strongest activity with an IC50 of 1,605.07 ppm. Groups containing black goji berry, either alone or in combination, consistently displayed better radical scavenging activity than Chinese jujube alone. These findings indicate that both black goji berry and Chinese jujube possess antioxidant potential; however, their combination, particularly in equal proportions, enhances this effect, suggesting a synergistic interaction. The results support the potential of these herbal mixtures as a complementary source of antioxidants to mitigate oxidative stress and prevent chronic diseases. They also highlight the value of studying plant combinations rather than single extracts.

Abstract

Adequate balance of nutrient intake is crucial due to its biological functions in supporting growth and muscle formation, particularly protein. Jackfruit seeds and mung beans are high-protein raw materials with potential for incorporation into protein-enriched foods, such as crackers. The purpose of this study was to determine the effect of jackfruit seed–mung bean composite flour fortification on protein content and sensory acceptability, and to identify the optimal fortification ratio in crackers. This experimental study employed a Completely Randomized Design (CRD) with five treatments representing different wheat-to-composite flour ratios. Data were analyzed using one‐way ANOVA to test for significant differences, followed by Duncan’s multiple range test to identify the best treatment. Findings indicated that the highest protein content (11.13 %) was achieved in treatment P5 (50 % wheat flour: 50% composite flour). Panellists rated color at 3.93 (like), aroma at 3.56 (like), texture at 3.86 (like), taste at 3.63 (like), and overall acceptability at 3.70 (like). The optimal fortification ratio was identified as P2 (80 % wheat flour: 20% composite flour). Fortification of crackers with jackfruit seed–mung bean composite flour enhances protein content and maintains favorable sensory attributes, with an 80:20 wheat-to composite flour ratio yielding the best overall results.

Abstract

Researchers have widely reported that Kombucha is a probiotic drink with health benefits. Some researchers are innovating to find other kombucha media sources besides tea that contain high bioactive compounds. Kecombrang flowers contain high bioactive compounds and have physiological functions for health, but this plant has not been widely explored for other innovative beverage or food products. This study aimed to determine the optimal fermentation time of kecombrang flower kombucha (Etlingera elatior) to produce the highest antioxidant activity during fermentation. The experimental design used was a complete randomized design (CRD) with 7 variations of fermentation time (days 0, 3, 6, 9, 12, 15, and 18) with a sugar concentration of 10% b/v, and this treatment was repeated four times. In this research, pH, total acid, and total flavonoid tests were also carried out to see the characteristics of the kecombrang flower kombucha drink during fermentation. Data analysis was performed with an ANOVA at P < 0,05. The results showed that the length of fermentation time had a very significant effect (P < 0,01) on the antioxidant activity of Kombucha. These results indicate that the size of fermentation time affects the antioxidant activity of kecombrang flower kombucha. Optimal antioxidant activity was obtained after the kombucha drink was fermented for 6 days, as indicated by the low IC 50 value of 37,73 g/mL, with a pH of 3,7, total acid of 0,33%, and total flavonoids of 5,9 mg/L QE. Based on a research study, kecombrang flower kombucha has strong antioxidant activity (IC50 < 50 ppm), so kecombrang flower kombucha can be used as a choice for functional drinks.
