Abstract

Microencapsulation techniques have been used to improve the stability of carotenoids and in the development of food fortification. The aim of this study was to determine the effect of the ratio of the coating material formulation (maltodextrin (MD) and soy protein isolate (SPI)) to the core material crude palm oil (CPO) on the physicochemical characteristics of the CPO microcapsules. Microencapsulation were carried out with ratios of coating material (MD:SPI = 2:1(w/w)) and CPO of 1:1.0, 1:1.2, 1:1.4, and 1:1.6 (w/w). The mixtures were homogenized at 12.000 rpm for 3 minutes and then spray dryed at inlet temperature of 180°C and outlet temperature at 80°C. The CPO microcapsules were analysed for yield, moisture content, solubility, and encapsulation efficiency. The results showed that the formulation ratio of 1:1.6 (w/w) was the best because it had the highest yield (20.12±0.02%), total carotenoids (295.2±0.32 µg/g) and encapsulation efficiency (59.95±1.50%). The best CPO microcapsules had spherical shape and smooth surface with an average size of microcapsules of 1-12 μm. The results of X-ray diffraction (XRD) showed that microcapsules were in crystalline state with crystallinity and amorphous value of 69.3 and 30.7%, respectively.

Abstract

 Betle leaf (Piper betle L.) essential oil and catechu nut  (Areca catechu L.) extracts have been known to be able to inhibit biofilm formation of S. mutans. This research aimed to characterize the chemical compounds of betle leaf esssential oil, screen the phytochemicals in catechu nut ethanol extract, and assess the inhibitory potential of betle and catechu in chewy candy on biofilm formation by S. mutans. The experiment included preparation of extracts and chemical characterization of the raw materials, formulation of chewy candy, measurement of biofilm inhibition, and sensory evaluation of the candy. In vitro examination for inhibitory potency of betle and catechu chewy candy against biofilm formation S. mutans ATCC 31987 was performed in adhesion phase (4 hours) and active accumulation phase (18 hours). Antibacterial assay was performed in BHI broth media on microplate 96 wells. Crystal violet 0.5% was used to stain the biofilm and Optical Density (OD) was measured at λ 450 nm. The GC-MS analysis detected 32 compounds in the essential oil of betle leaf. The Betle leaf essential oil contained chavicol acetate, isoeugenol, chavibetol acetate, chavicol, and allylcatechol 3.4-diacetate, while catechu nut ethanol extract contained flavonoids and tannins. The components were possibly the inhibitory agents of S. mutans biofilm formation. Chewy candy containing 0.8% betle leaf essential oil and 2.3% catechu nut extract had effective inhibitory potential for S. mutans biofilm formation. Inhibition during adhesion phase was 74.5±0.7%, while that for accumulation phase was 60.8±1.8%. Sensory analysis suggests that the candy was slightly liked by the panelists (5±2).

Abstract

Abstract. Shelf life of food products is one of the most important information listed on food packaging labels. A dry crisp food product has a relatively long shelf life with sogginess as damage parameters. This research is aimed to obtain a validated procedure for shelf life estimation of dry crisp food products by critical moisture content method, so it can be used as a standard procedure in shelf life estimation. The research was conducted with seven repetitions by using potato chips as food model and it started by determination of initial moisture content, critical moisture content, weight of dry food solids, other variables, and determination of MSI curve of GAB model to obtain slope b and equilibrium moisture content. Shelf life was calculated by using Labuza’s Equation, then shelf life data obtained and the parameters affecting it, were validated by using precision criteria based on Relative Standard Deviation (RSD) less than 2/3 RSDH (Horwitz equation) value. The result showed that both of shelf life data and all affecting parameters, has been validated. Shelf life at 75 and 80% RH were 22.21±0.08 months and 11.44±0.08 months, RSD value were 0.37 and 0.74%, as well as 2/3 RSDH value were 0.84 and 0.92% respectively. Thus, it can be concluded that procedure of shelf life estimation of dry crisp food products by using critical moisture content method was a valid and an appropriate method for its purpose, and can produce accurate shelf life calculation.
