Abstract

One factor that influenced colloidal structure is the composition of water, oil, and surfactant in the emulsions. This study aims to build a Winsor phase diagram of a mixture of water, eugenol, and Tween 20 and understand the physical differences in a range of micellar structures from the different compositions of the combinations. There were eleven samples with varying compositions of water, eugenol, and tween 20, and then were mixed and observed in parameters such as phase, appearance, and consistency. The results showed that the emulsion's compositions ingredients affected the character of the final emulsion. There were three categories of emulsions as described in the Winsor phase diagram. Water in oil (w/o) microemulsion was formed in the higher oil composition. In contrast, the lower oil content was macroemulsion/ coarse emulsion. The balance of oil and water composition was categorized as a bicontinuous microemulsion. This diagram will further help in constructing the suitable emulsion category for specific purposes.

Abstract

Food foams provide texture and structure for many food products, such as meringues. Meringues, a fundamental of culinary arts,  commonly consist of whipped egg white and sugar and have about most of the air phase. These types of composition allow for making different products with the same ingredients; thus, meringue design is essential to investigate foam stability and ability. This study aims to examine the foam stability of meringue using the different components such as protein as emulsifiers (egg white and gelatin) and the composition of sugars (icing and granule) on the foam stability and formation of meringue. Using gelatin as an emulsifier showed the foam more stable than egg white (>24 h), and adding the icing sugar with gelatin made the foam texture smoother. On the other hand, foam formation was faster when using emulsifier egg white, but stability was less than gelatin. The more stable foam produced by the combination of emulsifier and sugar ingredients would provide a better texture of meringue after baking, a smooth surface, no hole, and a more crunchy sweet taste. It was concluded that the composition of the ingredients and type of emulsifier would affect the stability and ability of foam, resulting in the character of the meringue after baking.

Abstract

Curcumin has been identified as the most abundant bioactive constituent in turmeric (Curcuma longa) extract (2 - 8% w/w). Curcumin is used as a preservative, flavoring, and yellowish colorant agent in the food industry. Modern scientific studies have confirmed its anti-inflammatory, antioxidant, anti-carcinogenic, and antimicrobial properties. Curcumin is easily oxidized and light-damaged, and it is insoluble in water. This product's shelf life should be increased. Curcumin microencapsulation into powder solves these issues. This process has been used because of its low cost, equipment availability, continuous production, and ease of industry. Curcumin powder in food could be crude turmeric powder (0.58 - 3.14%w/w), curry powder (0.11 - 0.58%w/w), or spray dried turmeric oleoresin curcumin powder (40 - 50%w/w). Spray drying coats the curcumin core material into the matrix powder, improving stability. The wall material (gum arabic, maltodextrin, or chitosan) and emulsifying agent were dispersed in continuous phase with the curcumin core material to prepare the microencapsulated flowing powders. Several formulation modifications in spray drying methods, such as co-dried and binary blend materials, have been investigated to improve the stability of curcumin. Curcumin powder is becoming more popular as a treatment for a variety of ailments, as well as a compound that is generally regarded as safe. As a result, its application as a nutraceutical or functional food has the potential to be expanded further.

Abstract

Coffee is a popular drink due to its special aroma and taste. Coffee contains caffeine that contributes a distinctive aroma to coffee, which can also be used as a quality parameter. However, if consumed excessively, it can have a negative impact on health. The decaffeination process using fermentation is one of the alternative methods to reduce the caffeine content without altering the characteristic taste and aroma of coffee. The objective of the study was to determine the influence of starter concentration (0-15%) and variety of coffee (Arabica and Robusta) in the decaffeination process using fermentation on reducing caffeine and the antioxidant activity of coffee products. The parameters were investigated regarding the chemical characteristics, including the concentration of caffeine, total flavonoid content (TFC), total phenolic content (TPC), and antioxidant activity tests using the DPPH free radical and FRAP methods. The results showed that the starter concentration and variety of coffee beans had a significant effect on the chemical characteristics (TPC and TFC) and antioxidant activity of decaffeinated coffee (p-value < 0.05). At a starting starter concentration of 5%, caffeine concentration was higher than a starter rate of 1% and did not significantly increase as stater up. Robusta coffee showed a higher decrease in caffeine compared to Arabica coffee.
