Abstract

Minimal processing of tomatoes (Solanum lycopersicum L.) have become increasingly popular due to their ability to preserve nutritional content and organoleptic characteristics. The minimal processing method offers advantages in minimizing natural changes in the product; however, the main challenge lies in maintaining the quality and freshness of the product during storage. This research aims to determine the shelf life of minimally processed tomatoes using the ASLT method with the Arrhenius model and to identify quality changes that occur during storage of minimally processed tomatoes. The Accelerated Shelf Life Test (ASLT) method proves to be an effective approach for predicting the shelf life of a product rapidly. The Arrhenius model, detailing the relationship between temperature and the rate of chemical reactions, is employed to analyze the kinetics of reactions during accelerated storage. The combination of these two methods provides an accurate overview of the product's shelf life. In this research, minimally processed tomatoes were packaged using wrapping plastic, HDPE (High-density polyethylene), and PP (Polypropylene), then stored at temperatures of 10°C and 30°C. The research results indicate that the highest pH value at 10°C with the wrapping packaging treatment was 3.6, and at 30°C, the highest pH value with wrapping packaging was also 3.6. The highest weight loss of tomato fruit at 10°C was observed with the wrapping packaging treatment at 1.25%, and at 30°C, the highest weight loss was 1.55% with wrapping packaging. The highest total soluble solids value was 4.27% with wrapping packaging at 10°C, and at 30°C, the highest total soluble solids in tomato fruit was 4.1% with wrapping packaging. The estimated shelf life of minimally processed tomatoes obtained results for the longest shelf life was wrapping packaging with an estimated shelf life of 15 days at 10°C, while the shortest shelf life was 2 days at 30°C with HDPE packaging. These findings provide insights into the stability of minimally processed tomato products and lay the foundation for the development of optimal storage strategies. The application of ASLT with the Arrhenius model can assist the food processing industry in enhancing efficiency and product quality, particularly in the case of minimally processed tomato products.

Abstract

This research investigates the impact of drying temperature on the antioxidant content of Beluntas leaf tea (Pluchea indica L.). Beluntas, a widely recognized medicinal herb, is renowned for its potential health benefits attributed to its antioxidant properties. This quantitative study employs a Factorial Completely Randomized Design with two factors: the drying time of Beluntas leaves (factor W) and the drying temperature (factor S). The research aims to evaluate the effects of drying time and temperature of Beluntas leaves on pH, yield, moisture content, antioxidant content, tannin content, and organoleptic properties of Beluntas leaf tea. Drying times of 120, 140, and 160 minutes were used, while drying temperatures were 50, 60, and 70°C. Beluntas leaf tea was then brewed with 200 ml of hot water at 90-100°C temperatures and steeped for 10 minutes. The results of the research can be summarized as follows: 1) Drying temperature and time significantly affect pH, yield, moisture content, antioxidant content, and tannin content. Higher drying temperatures and longer drying times decrease, pH, yield, moisture content, antioxidant content, and tannin content. 2) The optimal treatment of drying temperature and time to obtain optimal antioxidant content is in sample S1W2 (drying temperature of 50°C for 140 minutes) with a moisture content of 7.74%, pH of 5.92, yield of 74.66%, antioxidant content of 59.12%, and tannin content of 14.90%. 3) Based on organoleptic tests, the sample preferred by the panelists is S3W2 (drying temperature of 70°C for 140 minutes) with a tea color that tends towards greenish-yellow, slightly characteristic aroma of Beluntas, non-bitter taste, and a pleasant aftertaste. The results indicate a significant impact of drying temperature on the antioxidant content of Beluntas leaf tea, with clear trends observed with varying temperatures. Understanding the relationship between drying temperature and antioxidant content is crucial for optimizing the production process of Beluntas leaf tea to maximize its health-promoting properties. This research provides valuable insights into the cultivation and processing of Beluntas as a functional beverage with enhanced antioxidant activity.

Abstract

Functional food products have garnered significant attention, particularly among individuals seeking both palatable and nutritionally enriched dietary options. Among these, fish nuggets, as a processed fish product, emerge as a promising candidate for fulfilling daily nutritional requirements. This research aims to explore the quality characteristics of fish nuggets enriched with beluntas leaves and assess the fat and protein content, positioning them as functional food products. The research adopted a Completely Randomized Design (CRD) with two factors: beluntas leaves and mackerel, each featuring three distinct treatments. Beluntas leaf concentrations comprised 10%, 20%, and 30%, while mackerel concentrations included 90%, 80%, and 70%. Data analysis utilized Analysis of Variance (ANOVA), with subsequent application of the Duncan 5% test if significant treatment effects were observed. Results indicated that the most effective treatment for protein content was I1BI, exhibiting an average value of 88.66%. Meanwhile, the I1B3 treatment yielded the optimal fat content, averaging at 0.161%. This suggests that elevating the percentage of beluntas addition positively correlated with increased crude protein content, while significantly reducing fat content. This research contributes valuable insights into formulating fish nuggets with the incorporation of beluntas leaves as functional food. The outcomes serve as a foundational platform for advancing the development of functional food products based on fish, offering not only diverse flavors but also enhanced nutritional value. Such innovations align with the growing demand for healthier food alternatives and underscore the potential of fish-derived functional foods to address nutritional deficiencies and promote overall well-being.
