Abstract

Dragon fruit is one of the fruits with a fairly high water content which causes an increase in water activity and accelerates the growth rate of microorganisms. research was conducted to determine the shrinkage that occurs in the fruit. Two different sample sizes were used in this study. Both were cylindrical in shape with a diameter of 2.5 cm and different lengths. 3 cm (Sample A) and 1.5 cm (Sample D). The number of samples used for sample A and sample D was 5 pieces each. Measurements of weight and dimensions (sample length and diameter) were repeated every 15 minutes during the drying time at 45 ºC. Once the sample weight was constant, the material was put back into the oven at 105 ºC for 72 hours. After 72 hours, the sample was weighed and measured to determine the dry weight of the sample. Based on the study of the pattern of changes in the dimensions of red dragon fruit during the drying process, it can be concluded that the pattern of changes in volume ratio to KAbb is a linear pattern with an R2 value of 0.9946. The pattern of changes in volume ratio to KAbb is polynomial degree 2 and 3, but the R2 value is greater for degree 3, so degree 3 is more suitable for estimating the volume ratio of KAbb.values.

Abstract

Cherry tomatoes have a fairly short shelf life due to the influence of high water content and enzymes present in the fruit. Blanching is used to inactivate enzymes that can damage the quality of tomatoes. This research was conducted with the aim of studying the effect of blanching on the drying rate and sorption isotherm of cherry tomatoes. Blanching was done at 60 °C, 70 °C, 80 °C. After blanching, the samples were dried at 60 °C. After drying the samples were stored in a desiccator containing a solution for 24 days using NaOH, MgCl2, K2CO3, NaNO2, and NaCl. The results obtained in the blanching process have a lighter color than before blanching based on the L.a.b value. The moisture content of the sample during drying can be seen from the MR and drying rate which have almost the same value, only the time to reach 12% moisture content is different. The sorption isotherm process in the control treatment, blanching with temperatures of 60 °C, 70 °C and 80 °C with time (15, 30 and 45 minutes) experiences two processes, namely desorption (water release) at low RH and absorption (water binding) which occurs at high RH. The conclusion obtained is that the sorption process only occurs at 60 °C blanching with a time of 15 minutes at low RH and other treatments experience desorption.

Abstract

Statistical data shows that rice production increases every period along with the increase in demand. Harvested paddy must be dried immediately to avoid damage due to microbial attack that can live in high moisture content. Therefore, the main objective of drying is to reduce the moisture content from the harvest moisture content (23-27%) to a safe moisture content for storage (14%). Currently, there are several dryers made as a solution in post-harvest handling of grains such as green beans, soybeans, grain and so on. One example of this dryer is the Fluidized Bed Dryer. This tool is a mechanical dryer that can be used in drying grain. The advantage of this tool is that the temperature can be controlled and can produce quality and uniform drying results. The purpose of this study was to determine the drying characteristics of Inpari 42 grain using a fluidized bed dryer. This research method uses speed variations of 1.5 m/s, 2.0 m/s, and 2.5 m/s with sample masses of 200 g, 250 g and 300 g, using a temperature of 55 ℃. The research parameters include moisture content, drying rate, damaged grain. The drying process shows that the change in sample mass is influenced by the air velocity used. Along with the increase in moisture content, the drying rate will affect the rate of drying obtained in this study the drying rate pattern is decreasing. It can be concluded that air velocity affects the drying rate and air velocity affects the cracked grain.
