Abstract—Main problem in the processing of Dioscorea alata’s tuber into flour is the changing of colour. One factor in color changing is attributed to antocyanin reaction in the tuber. Several methods can be applied to minimise the browning and hence maintain the natural colour preferred by the consumers. This research was conducted to obtain the combination of age of harvest, blanching temperature and blanching length which produce the highest content of antocyanin in Dioscorea alata’s flour. The responses measured was anthocyanin content. The result showed that age of harvest was the main factor for anthocyanin content of Dioscorea alata flour. The optimum anthocyanin content is predicted to be achieved by using tuber harvested at 9.6 months, temperature of blanching 86.12oC and blanching time for 0.56 menit.

To evaluate the practicability of full substitution of eggs in production of a cake, different concentrations (0.5%, 1.0% and 1.5%) of xanthan gum were used. The results showed that substituting eggs with 0.5% xanthan gum inside a cake produced a harder cake and lower its moisture content, water activity and volume compared to control (1599.66 and 1945.69 g, 28.87 and 26.97%, 0.91 and 0.89, 523.33 and 425.00 cm3, respectively). The sensory evaluation result showed that the addition of 0.5% xanthan gum to an eggless cake received the highest acceptability among other eggless cakes. In conclusion, the addition of 0.5% xanthan gum produced the most promising substitute for eggs in cakes.

This study aims to determine the optimal temperature for drying kernel flour from tea seeds which will be used as raw material in the production of tea seed oil (TSO) by maceration method using n-hexane solvent. The study used a completely randomized design with 6 treatments for drying temperatures, namely: 60, 70, 80, 90, 100, and 110oC. The results showed that the optimal temperature for drying kernel flour from tea seeds was 80oC with a drying time of 3.5 hours. At the optimum temperature obtained TSO yield of 16.12% with free fatty acid content of 0.40%, iodine number 30.16 g I2/100 g of material, peroxide number 0.16 meq KOH /100 g, saponification number 144.55 mg KOH/g TSO, specific gravity 0.94 g/ml, refractive index 1.67, and melting point 2.0oC.

Coffea Liberica is a coffee plant that grow at lowlands and specifically on peatlands. Unlike Arabica and Robusta, Liberica coffee is large and able to grow up to 9 meters in height. Tea as a refreshing drink made from coffee skin which called cascara tea, had been developed in Indonesia and around the world. However, tea that made from green coffee skin is rarely been produced. This study used vary drying temperature (70, 80, 90℃) and time (12, 18, 24 hours). Refreshing drink products had a yellowish brown color with a hint of bitterness and tea leaves aroma. Drying condition with temperature of 90℃ and 12 hours of time duration is resulted in the most preferred beverage. The dried green coffee skin had 5.73% moisture content, 12.58% crude fiber, 4.78% ash content, pH 3.8, 9.95 of total polyphenols and 86.08 of antioxidant content.

Until now, no literature exists to explain about the impact of time, and environmental parameters, when using typical commercial grade transparent linear low density polyethylene (LLDPE) packaging for protecting vegetable cooking oil during typical shelf-life conditions. We tested long-term impact of temperature and illuminance (light: 100 to 150 lux and darkness <1 lux) on refined bleached deodorized palm olein (RBDPOL), fortified with vitamin A. Results showed degradation of fortified RBDPOL with 70 ppm vitamin A was approximately 15% at 18-22oC in Light, 10% at 18-22oC in Darkness, 19% at 32-33oC in light and 17% 32-33oC in darkness. Similar trend was observed at 45 ppm vitamin A. Exposure to heat and light impacted vitamin A degradation, but is primarily attributed to temperature, irrespective of packaging. This investigation builds on our previous work (Silalahi et al., 2017), and confirms the impact of challenging environmental conditions on vegetable cooking oil shelf-life over long time periods.

Avocado spread is an alternative condiment for a healthy consumption due to the abundance of unsaturated fatty acids in the avocado flesh. The avocado spread mixed with food hydrocolloids (guar gum, inulin, carboxymethyl cellulose) at 3% (w/w) was studied on rheology, texture, colour and sensory evaluation in comparison with no hydrocolloid addition. For the flow analysis, all spread formulations are the non-Newtonian shear thinning fluids. Addition of food hydrocolloids increased the viscosity, oscillation stability, and heat resistance. Inclusion guar gum with the fruit spread strongly affected the hardness and work of shear. The avocado spread added with inulin showed higher greenness than the other treatments. Among the spread samples containing 3% carboxymethyl cellulose secured the highest score for spreadability, colour, flavour, taste, and overall acceptability

The aim of this research was to study whether the frying time and temperature affected fatty acids profiles of blanched potato chips. Factorial designs were carried out using a completely randomized design (CRD) two factor (time and temperature) and three levels with two replications. Frying temperature was set up at 160 0C, 180 0C and 200 0C. The potato chips were fried for 3, 5, 7 minutes. The oil type used was sunflower. The fatty acids profiles were analyses with capillary gas liquid chromatography (Varian 3400) equipped with an auto sampler and a flame ionization detector (FID) using a 50 m x 0.32 mm (I.D) fused silica bonded phase capillary column (BPX70, SGE, Melbourne, Australia). The experiments were run in duplicate and the present results are the average of the obtained values. ANOVA analysis of the results was carried out using SPSS software (version 11, 2004). The key plot software for making three dimensions was the sigma plot scientific graphing software. The results showed moisture content and colour index of blanched potato chips decreased significantly with increasing frying time and temperature. Furthermore, unsaturated fatty acids (cis oleic and linoleic) decrease after long period frying.

The aim of the present study was to determine the proper concentrations of whey protein isolate (WPI), Arabic gum (AG), and Zedo gum (ZG) for the encapsulation of Nigella sativa seed oil (NSO). WPI, AG, and ZG were used as wall materials for the encapsulation of NSO by mixture design and then the optimum sample with minimum Z-average, PDI, and a* and maximum zeta potential, conductivity, encapsulation efficiency, and b* was selected for examining FT-IR and SEM. The findings demonstrated that lower particle size and particle dispersion index were obtained at higher amounts of AG and WPI with the least a*. Desirability function results indicate that the mixture of 39.05% WPI, 16.758% AG, and 4.192% ZG led to the production of the optimum sample. Microencapsulation of Nigella sativa seed oil using the optimum wall composition was recognized to be useful to preserve bioactive compounds and provide flavor stability, enabling the use of microcapsules in food formulations.

Observations about the impact of environmental parameters and time, on fortified vegetable oil, using typical commercial grade linear low density polyethylene (LLDPE) packaging during typical shelf-life conditions, are minimal. We tested the long-term (12 months) impact of temperature and illuminance (light: 100 to 150 lux and darkness <1 lux) on refined bleached deodorized palm olein (RBDPOL), fortified with vitamin A, and without antioxidant. Results showed degradation of fortified RBDPOL with 70 ppm vitamin A was approximately 19% at 18-22oC in Light, 18% at 18-22oC in Darkness, 38% at 32-33oC in light and 24% 32-33oC in darkness. A similar trend was observed at 45 ppm vitamin A. Exposure to both heat and light impacted vitamin A degradation, but was primarily attributed to prolonged exposure at elevated temperature, irrespective of the packaging material. This short study validates extensive research by Silalahi et al., (2017), doi:10.1111/ijfs.13462 on the impact of environmental effects of fortified vegetable frying oil, during extensive storage life periods.
