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

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.
