2023-03-08T05:21:46+00:00

Tapak dara flower (Catharanthus roseus) is an ornamental plant originating from Central Amerika. This natural pigment derived from the tapak dara flower is made in powder with maltodextrin as a drying agent. This experimental study uses a one-factor, Completely Randomized Design (CRD) research method with 3 levels of maltodextrin concentration, namely 20%, 30%, and 40%. The data obtained were analyzed statistically using the ANOVA test and continued with the DMRT as a posthoc test if there were significant differences. The results showed that adding maltodextrin with concentrations of 20%, 30%, and 40% and repeated twice had significant differences in water content, pH, level of sweetness (°brix), color, solubility, and total dissolved solids. The results of the chemical analysis of tapak dara corolla dye powder with a maltodextrin concentration of 40% had a water content, and the lowest pH was a water content of 4,90% and a pH value of 3,41. Maltodextrin concentration of 20% has the lowest sweetness level (°brix) of 5,35%. The results of the physical properties study showed that tapak dara corolla dye powder with 40% maltodextrin concentration had the lowest color brightness level (L*) of 32,91; the lowest reddish color level (a*) of 35,26 and yellowish color level (b*) the lowest is 35,26. The concentration of 20% maltodextrin has the lowest solubility and total dissolved solids, namely the solubility of 92,84% and the total dissolved solids of 5,35%. Adding maltodextrin with a concentration of 30% gave the best dye results based on water content, pH, level of sweetness (°brix), color, solubility, and total dissolved solids using the De Garmo method.

2023-03-07T04:07:58+00:00

Sago starch from traditional industries in West Kalimantan has a sour aroma and brownish color, so it is only used to make traditional cakes. This study aimed to evaluate the physicochemical sensory characteristics of bubble pearl tapioca substituted for sago starch produced from a traditional industry in West Kalimantan. The results of this study are expected to diversify the use of local sago starch. Bubble pearls were made with various proportions of tapioca and sago starch (100:0 90:10 80:20 70:30%) and analyzed for water content, hardness, cooking loss, cooking time, rehydration capacity, and hedonic analysis (color, taste, aroma, and Springiness). The results showed that substituting sago starch in bubble pearls affected the water content, hardness, cooking loss, cooking time, rehydration capacity, color, and aroma of bubble pearls. Substitution of sago starch does not affect the taste and elasticity of the bubble pearls. A higher substitution of sago starch increased the bubble pearls' water content, hardness, and rehydration capacity. A higher substitution of sago starch decreased cooking loss, cooking time, color, and aroma of bubble pearl decreased. Sago starch from the local traditional industry of West Kalimantan can be used to substitute tapioca bubble pearls. However, panelists prefer bubble pearls from 100% tapioca in terms of color and aroma. Sago starch from the local industry has the potential to be used as bubble pearls by improving the color and aroma of sago starch.

THE EFFECT OF THE ADDITION OF NaOH IN WATER DEGUMMING AND ALKALI REFINING PROCESS TO THE QUALITY OF RED PALM OIL OLEIN (RPOO)

2023-03-30T05:42:25+00:00

Red Palm Oil Olein (RPOO), obtained from Crude Palm Oil (CPO) processing, can be a potential source of provitamin A due to its high carotene. Water degumming and Alkali refining are alternative methods that are not widely used to remove gum and Free Fatty Acids (FFA) in making RPOO with relatively low heating temperatures. This study aims to determine the effect of increasing the amount of NaOH during neutralization on RPOO yield, FFA levels, β-carotene content, vitamin A, and preference level for RPOO. This study used Complete Randomized Design (CRD) with one treatment factor, namely variations in the addition of the amount of NaOH. The results showed that the variation of the addition of NaOH had a significant effect on decreasing FFA RPOO to range from 0.24 to 0.07. The content of β-carotene produced ranges from (635.87 to 645.54 ppm) and the content of provitamin A ranges from (105.97 to 107.59 μgRE). In addition, the RPOO yield decreased with an increase in NaOH use, ranging from (53.24 to 42.26%). Organoleptic tests showed that adding NaOH significantly affects the level of liking for the color and aroma of RPOO. Increasing the use of NaOH in alkaline refining could produce RPOO with good quality, but at the same time, it could reduce the yield of RPOO produced.
