Abstract

The advancement of post-harvest technology in Indonesia has provided accurate models for predicting grain behavior during storage. This study aimed to determine the best sorption isotherm model for describing the equilibrium moisture content of Ciherang and Ciliwung rice varieties. Rice samples were stored in 18 desiccators containing salt solutions with relative humidity (RH) levels of 10–80% at temperatures of 30, 40, and 50°C. Water content parameters were measured and three models (Oswin, Kuhn, and Chung-Pfost) were evaluated based on their coefficient of determination (R²). The results indicated that the Chung-Pfost model yielded the highest R² values for both varieties. For Ciherang, the R² values were 0.921 (30°C), 0.938 (40°C), and 0.931 (50°C), while Ciliwung showed R² values of 0.894 (30°C), 0.915 (40°C), and 0.920 (50°C). The study concluded that the Chung-Pfost model effectively represents water absorption behavior in these rice varieties, with higher temperatures reducing the equilibrium moisture content

Abstract

This study investigates the effects of hot water blanching and air velocity on the color stability of chilli (Capsicum frutescens L.) during thin-layer drying. The objective was to determine optimal pre-treatment and drying conditions that preserve visual quality and enhance drying efficiency. A controlled laboratory-scale dryer was used, applying blanching at 90°C for 3 minutes and air velocities of 1.0 m/s and 1.5 m/s. Color parameters (L*, a*, b*), total color change (?E*), and hue angle shift (?H*) were measured periodically. Statistical analysis was conducted using ANOVA and Tukey HSD tests. The results show that blanching significantly improved color retention and reduced enzymatic browning. Higher air velocity accelerated drying and enhanced uniformity, with the combination of blanching and 1.5 m/s airflow yielding the best outcomes in terms of color stability and drying time. Interaction effects between blanching and airflow were synergistic, contributing to improved product quality. These findings align with previous studies and reinforce the importance of integrated drying strategies. In conclusion, the study demonstrates that combining blanching with optimized airflow enhances drying kinetics and preserves the visual quality of chili. These insights are valuable for small-scale processors and contribute to the development of efficient postharvest technologies. Future research should explore nutrient retention, aroma profiles, and advanced modeling of drying behavior.

Abstract

Post-harvest handling, particularly fermentation and soaking, significantly affects cocoa quality. This study investigates the effects of fermentation duration (3, 5, 7 days) and soaking time (1, 2, 3 hours) on the moisture content of MCC 02 cocoa beans. The fermented beans were sun-dried, and moisture content was analyzed using the wet/dry basis method. Results showed the lowest wet basis moisture content of 55.65% for beans fermented for 3 days and soaked for 1 hour, and the highest of 63.1% for beans fermented for 3 days and soaked for 2 hours. After drying, the control sample had a moisture content of 7.7% (63.5% before drying), while the lowest moisture content for beans fermented for 5 days with 1-hour soaking was 7.95%, and the highest was 10.65% for beans fermented for 3 days with 1-hour soaking, exceeding the SNI standard (6-7%). Temperature fluctuations (28 - 37°C) and weather-dependent drying prolonged the process, resulting in higher moisture content than the standard, indicating the need for controlled drying methods.

Abstract

Coconut water (Cocos nucifera L.) is a natural beverage widely recognized for its high nutritional and health benefits. It contains essential electrolytes such as potassium, magnesium, and calcium, along with various vitamins and antioxidants; however, the quality deteriorates over time during storage. This study compares changes in the quality of young and mature coconut water stored at cold and ambient temperatures over a specific period of time. The research method includes measuring turbidity levels, pH, and total dissolved solids (TDS). The results indicate that both young and mature coconut water experience degradation in quality during storage, although at different rates. Storage at ambient temperature leads to a more rapid decline in quality than cold storage for both maturity types. Additionally, microbial growth is more frequently detected in coconut water stored at ambient temperature, particularly in mature coconut water. This study summarises that the quality of young and mature coconut water is influenced by storage temperature, with mature coconut water deteriorating at a higher rate. These findings can be recommended for storing coconut water at cold temperatures and consuming it shortly after opening it.

Abstract

The isotherm shorpsi curve is essential for estimating drying time, packaging, and material stability during storage. Based on the static method, the equilibrium moisture content of the material is obtained in a state of still air at a constant temperature. This research aims to make an incubator with constant temperature control. The method used in this study consisted of several stages, namely the design and assembly of the device, sensor calibration, and temperature rise testing. The results of the calibration of the tool show an average value of R2 = 0.998. This value indicates that the temperature readings from the sensor used with the mercury thermometer readings are very close. The temperature rise in the storage room experiences a constant increase until it reaches the setting point.

Abstract

Freeze drying is an effective method for preserving heat-sensitive fruits such as dragon fruit (Hylocereus costaricensis) by removing moisture through sublimation. This study aimed to evaluate the effect of blanching pretreatment on the quality attributes of freeze-dried dragon fruit, including moisture content, color, total soluble solids (TSS), and texture. A completely randomized design with two treatments (blanched at 90°C for 3 minutes and unblanched) and three replications was employed. Samples were cut into 1 mm and 3 mm thicknesses and freeze-dried at –50°C and 20 Pa for 24 hours. Results showed that blanching significantly reduced moisture content (final difference ≈1%), but also led to greater color degradation (lower L∗  and a∗  values, higher ΔE) and softer texture compared to unblanched samples. TSS values were lower in blanched samples. In conclusion, blanching enhances drying efficiency but compromises color, texture, and soluble solids retention in freeze-dried dragon fruit.
