Abstract

A Calcium is an important macromineral that plays a role in bone and tooth formation and helps maintain bone density. Calcium deficiency can increase the risk of osteoporosis. Tuna bone meal is a fairly high source of calcium that can be used as an ingredient in food products such as nuggets. The objective of this study is to help identify and develop alternative calcium sources that can be used in functional food products, such as tuna fish bone flour (Thunnus sp), which has the potential to increase calcium intake in the community. This study used a non-factorial Complete Randomized Design (CRD) consisting of three treatments: P1 (30% tuna fish bone flour), P2 (40% tuna fish bone flour), and P3 (50% tuna fish bone flour). Hedonic testing was conducted on the attributes of color, aroma, taste, texture, and overall quality using a scale of 1–5 by 33 moderately trained panelists. Calcium content analysis in the nuggets was performed using the Atomic Absorption Spectrophotometry (AAS) method. Statistical analysis used the Kruskal-Wallis test and the Mann-Whitney test. The preference test results showed no significant differences in color (p=0.251), aroma (p=0.308), and texture (p=0.643), while there were significant differences in taste (p=0.036) and overall quality (p=0.038). The preference test results showed that panelists preferred formulation P1 in terms of color, aroma, taste, and overall quality, making P1 the best formulation with a calcium content of 3.29%. One serving of tuna fish bone flour nuggets (40g) can meet ±100% of the daily calcium requirement.

Abstract

Diabetes mellitus is a metabolic disease whose prevalence continues to increase and is associated with high sugar consumption. One of the strategies for managing diabetes is the development of low-calorie functional beverages that remain sensorially acceptable. This study aims to test the acceptability and analyze the total sugar content of soft drinks based on roselle flowers (Hibiscus sabdariffa L.) and stevia (Stevia rebaudiana Bertoni) as a natural zero-calorie sweetener. This research uses an experimental method with a non-factorial Completely Randomized Design (CRD). Four formulations were tested, namely: F0 (2.5% roselle + 16% granulated sugar), F1 (2.5% roselle + 0.5% stevia), F2 (2.5% roselle + 0.7% stevia), and F3 (2.5% roselle + 1% stevia). A hedonic test was conducted on the parameters of color, aroma, taste, and texture by semi-trained panelists with inclusion criteria (students had already received material related to hedonic testing, were willing to be panelists, were physically and mentally healthy, and had eaten more than 30 minutes prior) and exclusion criteria (flu or anosmia, ageusia or loss of taste, a history of stomach acid, and smoking). Data were analyzed using Kruskal-Wallis followed by Post Hoc Mann-Whitney. The results of the hedonic test for taste (p=0.0039) and color (p=0.0035) attributes showed significant differences, while there were no significant differences for aroma (p=0.2796) and texture (p=0.1975) attributes. Post-hoc analysis showed that F1 was preferred over F3. The total sugar content of F1 was 9,74%, while that of F0 was 7,54%. The independent t-test showed a significant difference between the total sugar content of F1 and F0 (p=0.0003).
