Abstract

This study aimed to analyze the effect of different boiling time on protein content, total soluble solids (TSS), and sensory characteristics, including taste and aroma, of probiotic soy milk (Glycine max L.). The experiment was conducted using a Completely Randomized Design (CRD) consisting of four boiling time treatments of 5, 10, 15, and 20 minutes, each replicated three times, resulting in a total of 18 experimental units. The observed parameters included protein content, total soluble solids (TSS), and sensory evaluation performed by trained panelists using a hedonic test (five-point scale). Scores ranged from 1 (“dislike extremely”) to 5 (“like extremely”), where higher values indicated greater sensory preference. The collected data were statistically analyzed using Analysis of Variance (ANOVA), and when a significant difference was observed (p < 0.05), the analysis was continued with Duncan’s Multiple Range Test (DMRT) at a 5% confidence level. Data processing was performed using SPSS version 25. The results showed that boiling time had a significant effect on protein content, total soluble solids, and hedonic scores for taste and aroma attributes. The 15-minute boiling treatment produced the highest protein content (3.11%), optimal TSS value (8.9 °Brix), and the highest acceptance scores for both taste and aroma. Therefore, boiling at 95–100°C for 15 minutes can be considered the optimal condition to produce probiotic soy milk with the best balance between protein stability, total soluble solids concentration, and sensory quality.

Abstract

The phytochemical profile of tea beverages under different brewing conditions should be further examined using sensory evaluation to measure preference levels, which are essential for product development. This study aims to comprehensively review the sensory profile of tea beverages with different adjustments to the brewing conditions from recent 10-year publications. This study used the methodological standards outlined in the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols (PRISMA-P) across five databases (Scopus, Web of Science, ScienceDirect, ProQuest, and CABI). The Office of Health Assessment and Translation (OHAT) was used for risk bias assessment. A total of 1555 articles were identified, yielding 24 eligible studies. Various brewing conditions were identified in the study, mostly adjusted across three parameters: tea-to-water ratio, brewing temperature, and brewing duration. Preference level quantification is conducted using different hedonic scales with varying point levels, including 3-point, 5-point, 9-point, and 10-point scales. The quality assessment of tea is measured using various standards, including: Chinese national standard for sensory evaluation of tea, Check All That Apply (CATA), Percentage grading system, unstructured quantitative descriptive analysis, and degree of satisfaction difference. It could be concluded that studies about brewing condition in tea are focused on hot brewing and cold brewing with the optimum value of tea to water ration is 1:50. The sensory evaluation of tea from this different brewing condition is mainly conducted by trained panelists using 10-point hedonic scales as quantitative preference level and Chinese national standard for sensory evaluation of tea as a quality assessment method.

Abstract

Rice husk charcoal powder is traditionally used in Indonesia as a natural black food colorant, offering potential as an eco-friendly additive while valorizing agricultural waste. However, ensuring its food safety is critical for broader market adoption. This study evaluated the safety and production quality of rice husk charcoal powder produced by a small-to-medium enterprise (SME) in Purworejo Regency, Central Java, using a combined Good Manufacturing Practices (GMP) assessment and laboratory testing. GMP compliance was assessed against 18 parameters outlined in the Indonesian Ministry of Industry Regulation No. 75/M-IND/PER/7/2010, scored on a 0–60 scale. Laboratory analyses measured heavy metal content, moisture, ash, pH, and Salmonella contamination. The facility scored 480/1,080 points (44.44%), classified as Category C (Adequate), with key deficiencies in process monitoring, product labeling, documentation, and recall procedures. Major deviations were linked to open-air carbonization and uncovered cooling, while minor deviations included partial personal protective equipment (PPE) use and semi-open storage. Laboratory results confirmed compliance with safety standards, with Pb <0.04 ppm (≤1.0 ppm limit) and negative Salmonella detection. However, moisture content (18.86%) exceeded typical thresholds for dry powdered additives, correlating with suboptimal storage and drying practices. The findings indicate that while the product meets basic food safety requirements, targeted infrastructural upgrades, improved moisture control, formalized SOPs, and enhanced worker training are essential to elevate GMP compliance and support domestic and export market readiness for natural food colorants.
