Abstract

This research was conducted to determine the effect of the addition of CPO (Crude Palm Oil) lecithin as an Emulsifier on the physicochemical and sensory characteristics of dark chocolate, and to determine the amount of lecithin addition as an appropriate Emulsifier to produce chocolate with the best physico-chemical and sensory characteristics. This study used a completely randomized design (CRD) method with a treatment level of 0%. 0.1%, 0.2%, 0.3%, 0.4% with 4 repetitions to obtain 20 experimental units. Parameters observed included color degee, antioxidant activity, fat blooming, stability level, color sensory test, taste, aroma, texture and overall acceptability. The data obtained were analyzed using ANOVA levels of 1% and 5%. If there is a significant effect on the treatment, it will be continued with the Duncan's Multiple Range Test (DNMRT) at the 5% level. The best concentration of adding lecithin to dark chocolate is 0.3% which contains 66.76% antioxidant activity, color degee L*28.58, a* 13.67, b* 22.67, hue 58.75, good stability (melting properties), able to prevent fat blooming, has good color very chocolatey (4.20), very distinctive aroma of chocolate (4.44), bitter taste (2.68), smooth texture (3.36) and the overall acceptance of the panelists really liked it (8.16).

Abstract

Abstract— This research was conducted in two stages, first stage, looking for the best concentration of natural sweetener with organoleptic. Second stage analyzed the physicochemical characteristics using the best concentration of first stage. This research was carried out using a Completely Randomized Design, with various natural sweeteners consisting 6 levels, namely: stevia sweetener (0.05%, 0.75%, 0.10%), sorghum sugar (10%, 15%, 20%), corn sugar (10%, 15%, 20%), coconut sugar (14%, 15%, 16%), palm sugar (7.5%, 10%, 12.5%), and honey (15%, 25%, 35%) and 3 replications so that 18 experimental units. The addition of various types of natural sweeteners significantly affected the hedonic test (taste and overall acceptance), water content, pH, total dissolved solids, total sugar, and color but did not significantly affect the hedonic quality test (texture), hedonic test (texture and color), crude fiber content, syneresis and gel hardness. Keywords— Agar, Natural Sweeteners, Rice Bran

Abstract

Abstract— This research aimed to identify the effect of the substitution of super red dragon fruit peel (Hylocereus costaricensis) towards the physical and organoleptic characteristic of low-fat ice cream, todeterminethe best formulationof the Substitution of super red dragon fruit peel (Hylocereus costaricensis)intolow-fat ice creamand to determine whether the best formulation of low-fat ice cream with the substitution of super red dragon fruit peel (Hylocereus costaricensis)is as acceptable as commercial ice cream. This research was designed using a completely randomized design (CRD) with the substitutionof super red dragon fruit peel (0, 6, 8, 10, and 12% w/w) as the treatments. The parameters of overrun, melting time, viscosity, colour (L*, a* and b* values), and organoleptic evaluation including hedonic quality of colour and texture and overall acceptance were analyzed. The best treatment of organoleptic evaluation then was analyzed by paired comparison evaluation method with commercial ice cream. The result showed that the substitutionof super red dragon fruit peel was significantly different (P<0,01) on overrun, melting time, viscosity, colour (L*, a* and b* values), hedonic quality of colour and texture, and overall acceptance. The substitutionof 8% super red dragon fruit peel was found to be the best treatment based on organoleptic evaluation with overrun of 38,40%, melting time of 16,11 minutes, viscosity of 551,03 cP, colour; L* 63,80, a* 12,78, b* 19,25, hedonic quality of colour 3,10 (pink), texture 4,15 (smooth, non-snowy) and overall acceptance 4,45 (like moderately). The best formulation of low-fat ice cream with the substitution of 8% super red dragon fruit peel was not significantly different on the paired comparison evaluation with the score of 0,20 (Similar). Keywords— Ice cream; Low-fat; Peel; Super Red Dragon Fruit.
