Abstract

Edible casing which has good mechanical properties can substitute synthetic packaging to protect products from the evapouration of water, O2 and CO2 transmission, extend shelf life of product and prevent environmental pollution and it can be consumed along with product which packed in it. Therefore, it is important to evaluate permeability of edible casing in order to determine the value of water vapour transmission, O2 and CO2 gas transmission and thickness. The aims of this research were to determine the amount of water vapour transmission by following ASTM Standard E-96 and and evaluate gas permeability. The gas barrier properties of the casing films were analysed using manometric method (ASTM D 1434). The experimental design used in this research was Randomized Block Design with 2 factors; plasticiser type (glycerol, sorbitol, sucrose) and garlic concentration (2.5%, 5%, 10%) with three replicates. The properties evaluated were thickness and value of O2 and CO2 gas transmission. The results showed that type of plasticiser and concentration of garlic affect significantly on thickness, water vapour transmission, O2 and CO2 gas transmission. The interaction of two factors has also significantly affected on thickness, water vapour transmission, O2 and CO2 gas transmission. The best combination according to Zeleny method was obtained on sucrose plasticiser and garlic 5% with thickness 0.073 mm, water vapour transmission 0.56 g/m2/h, O2 gas transmission 1.6 × 10-4 cc.mm/m2.24h.kPa and CO2 gas transmission 3.4 × 10-4 cc.mm/m2.24h.kPa.

Abstract

Fresh fruit respiration information is essential optimizing food storage systems. Meanwhile, respiration is defined as the process of oxygen production and carbon dioxide release during storage in a closed respiratory chamber. Therefore, this study aims to design a low-budget computerized respiratory chamber for enhancing fruit packaging and storage system. Real-time fruit respiration can be measured by applying wireless gas sensors network. The respirometer consisted of 3,600 mL glass jar with a screw stainless lid, while the electrochemical and non-dispersive infrared sensors were mounted on the cover of the glass jar for collecting data on the oxygen, carbon dioxide, and temperature during mangoes’ respiration. Arduino USB port was used to record all measured parameters consisting of oxygen (%) and carbon dioxide concentrations (ppm, as well as temperature in the respiration chamber. Additionally, a controlled cooling chamber was applied to maintain the temperature during storage, while data communication was supported by Xbee S2C based on radio frequency. According to the respirometer real-time reading, there was a decrease in oxygen concentration caused by increasing carbon dioxide release with temperature. The low-budget respirometer was used to measure the respiration rate and record the data through a wireless sensor network system. The data plot shows that the respiration rate increased as the storage temperature and the respiratory quotient ranged from 0.32-0.44.

Abstract

Oxygen scavenging active film can be used to prevent diffusion of free oxygen due to the action of permeation mechanism. In this study, biodegradable oxygen scavenging plastic film was designed by incorporating an antioxidant agent into plasticized polylactic acid or PLA-PEG (PPLA). Butylated hydroxytoluene (BHT) was added at different concentrations into the matrix of the PPLA film using a direct casting method to produce oxygen scavenging active film. The antiradical activity of the oxygen scavenging active film was observed, which could be applied for preventing vitamin C degradation in cut lemon during storage. The antiradical activity of the active film composite reduced after 4 days of storage at 28 °C. Initial antiradical activities were measured at 99.90%–99.91% after introducing 1%, 5%, and 10% concentrations of BHT into the matrix of the PPLA film. DPPH analysis indicated that a larger concentration of BHT exhibited higher antiradical activity after 4 days of storage surrounded with free oxygen. The final antiradical activities were 35.45%, 54.56%, and 81.65% at 1%, 5%, and 10% BHT concentrations, respectively. Therefore, incorporating a higher BHT fraction into the oxygen scavenging active film composite can certainly prevent the oxidation of cut lemon. The respective final vitamin C levels were 13.5%, 20.6%, and 22.5% after 4 days of storage.

Abstract

            Lerak (Sapindus rarak DC.) is one of the fruits with a main active compound called saponin. Saponins function as natural surfactants with foaming and emulsifying properties. Lerak in Indonesia is widely used as a traditional detergent. Using lerak essence as a detergent, batik washing can be done well without fading colors and is more environmentally friendly. Lerak essence can be applied as an additional component in preparing solid laundry soap. Adding lerak essence is to replace the anionic surfactant Sodium Lauryl Sulfate (SLS). Therefore, the risk of pollution can be lowered, as well as keep batik cloth from easily fading out. This study was conducted using Randomized Block Design (RBD) with two factors, including the concentration of lerak essence (10%, 7.5%, and 5%) and NaOH molecules (0.5 mol and 0.375 mol). This study aimed to analyze the effect of variation in lerak essence concentration and NaOH molecular on the physicochemical properties of solid laundry soap. The results showed that the higher the concentration of lerak essence and NaOH molecules, the more it reduces the water content in solid laundry soap. Concentrations of 10% lerak essence and 0.5 mol NaOH molecules have the highest value for foam stability and the lowest value for moisture content. Among the tensile strength, pH, brightness level and yellowness level, the highest value was in the concentration of 7.5% lerak essence and 0.5 mol NaOH molecules. Treatments of the variation of lerak essence concentrations significantly affect pH, while the treatment of NaOH molecular variation significantly affects pH, tensile strength, foam stability, brightness level (L*) and yellowness level (b*)

Abstract

Milk contains complete nutritional components such as fat, protein, calcium, vitamins and other minerals. To produce skim milk and cream, centrifugation technology is needed. Centrifugation is a method that uses the principle of sedimentation, where centripetal acceleration is used to separate substances that have different densities. By centrifugation it is possible to break down the emulsion and separate the dispersion of fine liquid droplets, although in this case the suspended phase is in the form of liquid droplets which will coalesce after separation. The purpose of this study were to analyze the effect of temperature and rotational speed of centrifugation on the physical properties and nutritional content of milk cream. This study uses two parameters, namely centrifugation speed and temperature. The variation in temperature used are 30, 40 and 50 ° C and the centrifugation speed are 6000.G, 7000.G and 8000.G. The results showed that centrifugation using the conical disc centrifuge was able to separate fat from fresh milk. The highest fat content is 20.42% and the highest protein is 1.577% at 6000.G centrifugation speed. Increasing temperature and rotation speed will increase yield, density, water content and conductivity of milk cream. On the other hand, it can shorten the processing time, reduce the viscosity and boiling point of milk cream.

Abstract

Tomatoes are fruits that contain a number of important nutrients, such as carbohydrates, vitamin C, vitamin A, vitamin B1, vitamin B2, lycopene, iron, fiber, minerals, and so on. However, tomatoes include climatic fruit, which will rot if not consumed immediately. Under these conditions it’s necessary to process tomatoes into potential products such as tomato paste. Tomato paste production is done by the evaporation process to remove some of the water content. But giving heat to evaporation can damage the nutritional content of the paste. Electroosmosis dewatering is method for reducing water content by placing colloidal suspensions between two electrodes. This method is an interesting to concentrate the suspension that is sensitive to heat. Based on this, research is needed to determine the effect of electroosmosis on reducing water content in tomato paste. In this study, the DC voltage variations used were 0 V, 4.5 V, 9 V, 18 V and 36 V with 100 minutes processing time. The parameters measured based on these variations are changes in DC current during the EOD process and water content of tomato paste. The results showed that DC electric current decreases with increasing processing time, and increases with increasing voltage. the electric current at the lowest voltage variation (4.5 VDC) is 41.40 mA - 59.7 mA, while the electric current at the highest voltage variation (36 VDC) reaches 231.86 mA - 776.67 mA. The increasing DC voltage, the tomato paste water content decreases, so the best stress for the dewatering process is 36 V.

Abstract

Extraction is one of the important processes for obtaining anthocyanins as natural dyes. The aim of this study is to investigate the performance of the extraction apparatus using ohmic technology to produce anthocyanins. This study used a series of ohmic heating consisting of tubular pipes with a diameter of 6 cm and a length of 5.5 cm with a volume capacity of 100 ml. This extraction machine was completed with two electrodes that each have a thickness of 10 mm. The performance of extraction machines using ohmic technology was analyzed by using various voltages of 20, 30, 40, 50, and 60 Volts/cm. The result showed that the voltage affected the electric current of the machine. The voltage of 60 Volts/cm was able to produce the largest average electric current of 5.28 A with the greatest electric current achievement of up to 6.21 A. The result showed that increasing the voltage during the extraction process reduced the time needed to reach the expected temperature. The fastest time was achieved in the voltage of 60 Volts/cm with an average time of 11.3 seconds. The increased voltage in the extraction treatment also affects the total anthocyanin produced. The highest total anthocyanin was obtained from a voltage gradient of 60 Volts/cm with a value of 288.014 mg/L and a yield of 14.4%.
