Abstract

Red fruits’ oil contains 12,000 ppm carotenoid compounds and among them β-karoten was found as the major carotenoid compound. However, the application of red fruits’ oil as the food ingredient is rarely investigated due to its low solubility in aqua-phase, phenolic aroma and bitter aftertaste. Therefore , emulsification of red fruits’ oil in water (oil in water, o/w emulsion) using CMC (carboxymethyl cellulose) as the emulsifier and stabilizer agent considered as alternative to overcome those limitations. In the present work, the optimum concentration of red fruits’ oil emulsion added into Java tea-based functional drink increased the total carotenoid content, gave red color and might enhanced its antioxidant activity. The optimum formula was performed by Response Surface Methodology approach utilizing Design Expert 10.0.7® (DX10) Trial software whereas the emulsion concentration of red fruits’ oil as the variable factor. Red fruits’ oil emulsion which has been prepared from 20% red fruits’ oil and 1.50% CMC as emulsifier and stabilizer was having total carotenoid content of 72.93±1.33 ppm. The optimum concentration of red fruits’ oil emulsion added to Java-tea based functional drink was 5.86%. The addition of red fruits’ oil emulsion increased the total carotenoid content from 0.37±0.13 ppm to5.28±0.05 ppm. The results showed that red fruits’ oil emulsion could be used as red colorant agent in the functional drink while increasing the total carotenoid content, however, reduced the flavor sensory acceptance in high amount

Abstract

Andaliman (Zanthoxylum acanthopodium DC.) is a plant endemic to North Sumatra. Its fruit has a very specific citrus-like aroma, gives a tingling sensation and is commonly used for seasoning in Bataknese traditional cuisine. To extend the shelf life and preserve the quality of andaliman fruit, post-harvest handling is needed. Seven drying methods were applied and compared, i.e. sun, air, fluidized bed, oven, far infrared, freeze, and spray drying. Considering the physicochemical and sensory properties and efficiency, oven drying was selected for further study. The optimum condition for drying was temperature at 54 °C for 8 h resulting in 0.67 desirability level based on the response surface method (RSM). Spray drying encapsulation of andaliman fruit extract was performed at an inlet temperature of 150 °C with an extract to carrier ratio of 1:8. Maltodextrin (MD) and gum arabic (GA) with a ratio of 3:2 was chosen as the carrier agent. The quantitative descriptive analysis (QDA) result showed that the encapsulated andaliman powder had a flavor that resembled fresh andaliman with a more pronounced taste, a citrus-like trigeminal sensation, and a sour floral citrusy aroma.

Abstract

This research was conducted to identify volatile compounds of pluchea and basil essential oils and their antioxidant capacity to scavenge a DPPH (1,1-diphenyl-2-picrylhidrazyl) free radical and inhibit lipid peroxidation. Essential oil of pluchea and basil leaves was prepared by hydrodistillation method and then their volatile compounds were identified by GC-MS. The volatile compounds in the essential oil of pluchea leaves consist of 66 components with (10S,11S)-Himachala-3-(12)-4-diene (17.13%) made up the highest proportion of volatile compounds. Basil leaves had 70 volatile components in which the major components were (E)-3,7-dimethyl-2,6-octadienal  (23.98%) and (Z)- 3,7-dimethyl-2,6-octadienal (17.35%). Total phenol levels in pluchea and basil essential oils were 275 and 209 ppm, respectively. DPPH scavenging activity of the essential oil of pluchea leaves was lower than that of basil leaves, conversely inhibition activity of lipid peroxidation in palm oil of pluchea essential oil was higher than that of basil leaves.

Abstract

Functional drinks containing the leaves of Java tea has been shown to offer many health functionalities, particularly to lower blood glucose levels, due to its bioactive compounds. Nanoencapsulation technology was reported being able to protect these bioactive compounds and also enhance their bioavailability. This study examined the use of nanoencapsulation techniques to improve the bioavailability of Java tea-based functional effervescent drink and enhance its antihyperglycemic activity. Three versions were prepared in this study: ready to drink (RTD) as the control, microencapsulated, and nanoencapsulated. They were all measured for their total phenolic content (TPC) before being tested for their antihyperglycemic activity. The TPC of RTD, microencapsulated, and nanoencapsulated Java tea-based functional drinks (JTFD) were 998,425, 735,433, and 663,517 ppm, respectively. The antihyperglycemic activities were evaluated by feeding each beverage to streptozotocin-induced diabetic Sprague Dawley rats for fourteen days. Nanoencapsulated JTFD was found to be more superior than the other two formulations to decrease the blood glucose level (7.98%), maintain the feed intake, body weight, improve the viability of Langerhans and beta-cells by 49.09%, 32.50%, respectively.

Abstract

Obesity has become a global health issue and is one of the factors that trigger degenerative diseases. The correct food consumption management could be a solution for treating obesity. Soybean is a food that is rich in bioactive components and has antiobesity properties through various mechanisms. In Indonesia, nearly 60% of the soybeans are consumed in the form of tempe. The process of fermenting soybeans into tempe causes a bioconversion of nutrients and bioactive components, improving the active physiological abilities. The bioactive components that play a role in the treatment of obesity are isoflavones, proteins, and peptides. These bioactive components help in reducing body weight, lowering the body fat ratio and improve lipid profile. Thus, optimation and popularization of tempe as a functional food in the daily menu supported with correct tempe processing could be a solution in treating obesity.

Abstract

Some Researches indicated that oryzanol had antioxidant activity, however, the information about the oryzanol role in the prevention of low density lipoprotein (LDL) and human lymphocyte from oxidation under oxidative stress was still limited. The objective of this study was the investigate the antioxidant activity of oryzanol at concentrations based on rice bran beverage model in preventing LCL and lymphocyte from oxidation. Human plasma were supplemented with the samples of : rice bran oil (RBO), unsaponifiable matter and oryzanol IR-64, oryzanol IR-64 3x and oryzanol standard at the concentrations of 308.3, 22.2, 5.2, 10.4, and 10.4 µg/ml, respectively. Afterward, the human LDL were collected by ultracentrifuge and diluted until a concentration of 200 µg protein/ml was reached. Human LDL isolates were then oxidized with CuSO4 5 µM for measuring antioxidant activity of the sample. The length of incubation, H2O2 concentration, period of sample supplemented into human lymphocyte culture were determined before the antioxidant activity of RBO and its fraction in lymphocyte was measured. The samples used in the lymphocyte were RBO IR-64, unsaponifiable matter IR-64, and oryzanol standard at the concentrations of 133.2 – 2, 132.0 µg/ml, 9.6 – 153.6 µg/ml, and 2.4 – 37.7 µg/ml, consecutively. The result showed that malonaldehyde concentration in human LDL decreased significantly (α = 0.05), 15 – 41% and 39 – 56% compared to the control. The absorbance of living lymphocyte cell in culture was not influenced by the type and concentration of RBO and its fraction. The addition of hydrogen peroxide (H2O2) 3 mM into culture sifnificantly lowered the absorbance as compared to culture without (H2O2). Key words :Oryzanol, oxidative stress, LDL-oxidized, lymphocyte and antioxidant activity.
