Zingiber Officinale Roscoe

Ginger is a spice plant that is usually used as a seasoning in cooking or raw material for medicine, traditional or industrial medicine. Ginger has a high-water content so its easily contaminated with microbes and has active ingredients (gingerol) which are easily damaged by high temperatures. Ginger drying is intended for maintaining the quality of dry ginger and keep ginger from microbes. The drying process has done in continuously with solar dryer using flat plate type collector during the day and at night using the Molecular Sieve 13x desiccant. Drying varies the thickness of ginger 2 mm, 4 mm, and 6 mm, and the amount ratio of desiccant: 1:1; 1:2; and 1:3.  To get drying characteristics, every 1-hour mass calculated using an electric scale, and data logger every 5 minutes calculates the temperature and humidity rate (RH) in the drying chamber. The result from ginger drying is the thickness of 6 mm needed more than 20 hours of drying process so that it needed the combination of dryer compared to other thickness, and from quality analysis results of dry ginger, ash content parameters already accordance with SNI standards, and 1:1 material and desiccant ratio is the variation that most closely matches the SNI standard.

The aim of this study was to determine the effect of differentiated air relative humidity during the drying process on selected quality features of TSG (traditional specialties guaranteed) pork and poultry-pork kabanosy. After heat treatment and 24-hour cooling at 4–6°C, the products were placed in three chambers at 15°C with differentiated air relative humidity: 60, 70, and 80%, respectively. The drying process was carried out until all variants of kabanosy achieved the required final yield of the product (<68%). Color components, water activity and shear force, water, protein, fat, and salt content, and the TBARS indicator values were determined. The drying process might be shortened (~50%) by a reduction of humidity in the drying chamber from 80 to 60%. The changes in the content of chemical components in pork kabanosy compared to poultry-pork ones demonstrated the different dynamics of the drying of the two types of kabanosy and the need for the selection of optimum drying conditions relative to raw material composition.
