Abstract

Shallots are an important food commodity for the needs of various Indonesian cuisines and other uses that are widely utilized. However, currently shallot farmers complain about post-harvest shallots that are easily damaged such as rotting, wrinkling, porous, root growth and fungal growth. To reduce this damage, preservation is needed. One alternative technology is Co-60 Gamma Ray Irradiation based on the principle of electromagnetic radiation that produces high-energy photons that cause ionization and excitation in the material it passes through. The nature of Gamma rays used in the preservation process has great penetrating power and does not cause temperature changes in the irradiated food. The purpose of this study was to determine the effect of Co-60 gamma ray irradiation on the optimization of the shelf life of post-harvest preservation of shallots with variations in control doses: low, medium and high, variations in temperature and quality parameters. The method of this research stage is: 1) Sample preparation. 2) Gamma Ray Irradiation of Co-60 with variation of control dose: low, medium and high 3) Analysis of temperature measurement and measurement of quality parameters (water content, weight loss, damage and hardness) against the irradiation dose. The results showed that gamma ray irradiation of Co-60 affected the length of shoots based on variation of dose and temperature, namely on day 1 and day 14 the combination of 650Gy treatment at 350C had the smallest shoot length, water content was relatively high, weight loss was relatively small, damage was relatively small and hardness was relatively high.

Abstract

Shallots (Allium ascalonicum L.) are a horticultural commodity that is highly susceptible to post-harvest damage due to their high moisture content. One effective method to extend the shelf life of shallots is through drying. This study aims to optimize the drying process of shallots using a food dehydrator at various drying temperatures (40°C, 50°C, and 60°C). The optimization was conducted by evaluating parameters such as moisture content, color, texture, flavonoid content, total phenolic content, and antioxidant activity. In addition, drying characteristics and drying rates, thin-layer drying models, rehydration ratios, and color changes were also analyzed to determine the optimal temperature for the dehydration process. The research methodology involved the following steps: (1) Preparation of materials and equipment, (2) Drying of shallots at 40°C, 50°C, and 60°C and analysis of moisture content, color, texture, flavonoid content, total phenolic content, and antioxidant activity, and (3) Statistical analysis of the data to determine the optimal drying temperature for maintaining shallot quality. The results of this study are expected to provide recommendations for effective drying parameters to maintain post-harvest shallot quality and to improve storage and distribution efficiency.
