Abstract

In the fractional distillation process, the pressure that used is one of the important factors determining the operating conditions to obtain optimal product. This research aims to determine the effect of pressure on the fractinal distillation process of patchouli oil. The research method that used in this research was an experimental method with descriptive analysis. This research was conducted with three treatments that is different pressure treatments and repeated twice. The pressure treatments that used in the fractional distillation process are A = 5 mmHg, B = 10 mmHg, and C = 15 mmHg and arranged to produce five (5) fractions of each treatment. The parameters that measured including the yield of fractional distillation, distillation process time, specific gravity, and refractive index. The lower the pressure used in the distillation process, the greater the yield and the faster the distillation process time. The results of this research indicate that the variation of pressure that used does not have a significant effect on the characteristics of patchouli oil such as specific gravity and refractive index. The application of 5 mmHg pressure is good enough to separate the distillate yield into 5 fractions and is more efficient because it obtains the highest total yield of 93.5% with a distillation process time of 18.16 hours.

Abstract

The needed for tomatoes was not comparable with the abundant of production, so tomato prices at the farm level were low. Tomato processing was needed to maintained and increased the selling value of tomatoes, it can be processed into tomato pulp powder. Tomato powder can be made by foam-mat drying method and to shortened the drying time can be done by using microwave oven. The purpose of this study was to determine the effect of the drying power used on physicochemical properties of tomato pulp powder and drying rate of foam-mat drying with microwave oven. This study conducted with laboratory experimental method with descriptive analysis. Three repetitions consisted of three treatments based on drying power used (30%, 50% and 70%). The observed parameters were total yield value, color, drying rate, drying efficiency and physicochemical properties such as color, foam density, bulk density, moisture content, ash content, water absorption index, and vitamin C content. The results showed that the average moisture content of tomato pulp was 91.73% (w.b.) and foamed tomato pulp was 90.86% (w.b.). The value of water content of tomato pulp powder ranges from 9.18% (w.b.) to 12.50% (w.b.). In this study, the best results were found in tomato pulp powder with 70% drying power without addition foaming treatment with total yield of 0.58%; 4.26 g/min drying rate; 5.86%; foam density 1 g/cm3; bulk density 0.65 g/cm3; moisture content; 9.18%; ash content 6.43%; water absorption index 19.68%; vitamin C content 154.87 mg/100g and drying efficiency was 48.27%. All of drying power used with and without foaming treatment were resulting yellow-red chromatic colour characteristic.

Abstract

Water loss by transpiration causes withering in tespong (water celeries). Crisping can be considered to maintain the availability of water in tespong. The crisping is a process of diffusing water into vegetables through a soaking process by employing the mechanism of opening and closing of stomata and other natural openings which is influenced by surrounding temperature. The purpose of this study was to determine the effect of temperature and soaking time on the crisping process in maintaining the freshness quality of tespong. Tespong samples were immersed at 30°C and 40°C soaking temperatures for 3, 5, 7, and 10 minutes of soaking time, followed by a cooling process in cold storage at 5±2 °C for 16 hours before being stored in a chiller at 8±2°C for 4 days. Tespong’s weight loss, moisture content, color, and texture were observed during the storage time. As a control treatment, 2 groups of tespong were prepared. Control 1 was placed directly in a chiller with a temperature of 5±2°C whereas control 2 was in a laboratory room. The results showed that crisping treatment with 30°C soaking temperatures and 3 minutes soaking time gave better results in maintaining tespong’s freshness where weight loss, moisture content, L, a*, b*, and texture were -5.67%, 89.36%, 52.40, -14.54, 23.84, and 388.44 g/d, respectively.

Abstract

Red ginger contains volatile components that are essential oils. Essential oils can be obtained through the distillation method. Hydrodistillation is a method of distillation that involves providing direct contact between the materials and water at a high temperature, which is influenced by several factors, including time and the solvent feed ratio (SF ratio). This study aimed to determine the best conditions for high yields and essential oil quality using SNI No. 06-1312-1998 as a reference. The research method used was experimental research, and optimization was carried out using Response Surface Methodology (RSM) with CCD design. The treatments for distillation were time (2 hours, 4 hours, and 6 hours) and solvent feed (SF) ratio (8:1, 10:1, and 12:1). The parameters observed were yield, residual solvent content, specific gravity, refractive index, and acid number. The results showed that the time and SF ratio variables had no significant effect on the yield but had a significant effect on the residual solvent content. The optimization process resulted in a time of 6 hours and a solvent volume of 720 ml (ratio 1:12), yielding 0.14 with a residual solvent content of 3,557%. The characteristics of the essential oils produced were 0.8794 for the specific gravity, 1.473 for the refractive index, and 2.13  for the acid number. Red ginger essential oil met the requirements of SNI ginger oil on the parameters of specific gravity and refractive index.

Abstract

Lemon contains essential oil compounds found in the peel, namely the flavedo. This section can produce essential oils by various methods, including the distillation method. Differences in distillation methods can affect the quality of essential oils. In the essential oil production process, paying attention to the distillation method and the samples of raw materials used is necessary. This study compares the process of extracting lemon peel oil using hydrodistillation and hydro-steam distillation methods.This research has enormous benefits for obtaining the best essential oils using a method that has stable quality and at a not too high cost. The process conditions are carried out by applying the influence factors of temperature, distillation time, and the ratio of raw materials to yield and aroma characteristics. The heating temperature is 100 oC, the distillation time is 4 hours, the raw material ratio is 1:5, as well as the pretreatment process of raw materials. The resulting steam is condensed, and the distillate, a mixture of oil and water, is separated using a separatory funnel. The oil is purified with anhydrous sodium sulfate (Na2SO4) to separate the oil from the remaining water. The best results were obtained from the research results in the hydrodistillation method with a heating temperature of 100 oC, a distillation time of 4 hours, and a raw material size of 1 cm with a % yield of 0.99%. As well as, the aroma produced is not too strong to get a value of 1 for the hydrodistillation method, and the aroma characteristics are quite strong with a scale of 3 produced by the hydro-steam distillation method. As well as the % yield value generated is 0.495%.

Abstract

Carrot pulp is a by-product of juice production with a source of pectin and carotene precursors of vitamin A. One way to use carrot pulp is through a drying process, such as convection drying, to produce carrot pulp flour. The purpose of this study was to determine the optimal conditions for drying carrot pulp using a food dehydrator, to determine the characteristics of carrot pulp powder under optimal conditions, and to determine the potential of carrot pulp powder in preparing peel off gel masks. The parameters in this study were moisture content, ash content, and drying yield. In addition, the parameters observed in the optimum carrot pulp flour were color and antioxidant activity. The dryer used was a food dehydrator operating at a temperature range of 45°C to 65°C for a duration of 20 to 26 hours. This research method was an experimental method with optimization using the Response Surface Methodology (RSM) type Central Composite Design (CCD) in the Design Expert 13 application. RSM determined the optimal drying process condition to be 65°C for 26 hours. This condition resulted in a product with a moisture content of 3.033%, an ash content of 5.326% and a drying yield of 11.062%. Carrot pulp flour produced under optimal drying conditions, when formulated into a peel off gel mask preparation, exhibited a drying time of 15-21 minutes.
