Abstract

Peanuts are one type of nuts that are quite a lot in Indonesia. Peanuts processing in Indonesia is still very limited. It is necessary to diversify the processing of peanuts into other food products. One of the efforts to diversify the peanuts process is to process them into flour. Peanuts have a weakness, namely, peanuts contain compounds of anti-nutritional substances which are mostly dominated by phytic acid and the presence of an unpleasant odor. This weakness can be overcome by the fermentation process. tempe is one of the processed products fermented in beans. The purpose of this study was to determine the functional characteristics of fermented peanut flour with variation in yeast concentration and fermentation time; and the best combination of the treatments. This study used a completely randomized design (CRD). The factors tested were the concentration of tempe yeast (3, 5 and 7%) and length of fermentation (24, 28, 32 dan 36 hours). The result of the study showed that all treatments had a significant effect on the functional characteristics of fermented peanut flour. The result shows that fermentation treatment with variations used increase the levels of water absorption capacity, solubility in water, total phenol, and antioxidant activity; but decrease the levels of oil absorption capacity and emulsion capacity. Fermented peanut flour with the best functional properties was obtained at 7% yeast concentration and 36 hours of fermentation (R3F4) treatments.

Abstract

Temperature and relative humidity are factors that affect the microbial profile and brix value of coconut sap. High temperature and relative humidity tend to support microbial growth. On the other hand, high relative humidity will reduce the brix value and total coconut sap sugar. Therefore, it is necessary to study the relationship between agro-climatic conditions with microbial profile, brix value and total sugar in organically run coconut sap in Gandatapa Village. This research is expected to provide benefits for those who need coconut sap as a source of S. cerevisiae and as a raw material for the manufacture of brown sugar. Coconut sap samples were taken using a simple random technique. Temperature and relative humidity were recorded for each sampling. 250 ml of coconut sap was put into a sterile plastic bottle and then using an ice box, it was taken to the Agricultural Technology Laboratory for analysis. The analysis carried out included total microbes, total yeast, total bacteria, yeast percentage, brix value and total coconut sap sugar. The data were analyzed using Pearson correlation to determine the relationship and the degree of closeness. The results showed that temperature and relative humidity were positively correlated with the microbial profile of organically dissolved coconut sap. At an air temperature of 28.4oC and an air humidity of 81%, the total microbes of organically run coconut sap were 6.45 logs, the total yeast was 4.28 log cfu/ml, the total bacteria were 2.52 log cfu/ml and the yeast percentage was 72, 75%. Brix values ​​and total sugar under the same conditions were 16.7% and 8.25%. The value of brix and total sugar of coconut sap is negatively correlated with temperature and relative humidity. There is a strong relationship between temperature and total microbial, brix value and total sugar. The correlation coefficient is 0.71, respectively; -0.81 and -0.78. Strong correlations were also observed between relative humidity and total microbial, total yeast and brix values. The correlation coefficient is 0.85, respectively; 0.82; and -0.83.

Abstract

Annatto pigment has the potential to be used as a natural dye. The addition of coating material is expected to act as a carrier and binder of annatto seed pigment in karak crackers. This study aims to determine the effect of the addition of annatto seed pigment and the type of coating on the color of coral crackers. Pigment coating is carried out using starch and maltodextrin. As a comparison, the pigment is directly added to the cracker dough, and as a control karag cracker is made without the addition of pigment. Coated annatto seed pigment was added as a colorant to the karag cracker dough with various concentrations of 2, 3, and 4%. Using the Munsen color dictionary, the potential of coated pigments as coloring agents was observed by measuring the hue, value, and chroma of the karag crackers. The results showed that the hue of karag crackers with the addition of annatto pigment produced a red color and mostly yellow-orange (YR) while the control (without the addition of pigment) produced a yellow color with a Hue (color) value between 2.5 to 5YR except for starch coating with a concentration of pigment 2% produces a red color. The use of maltodextrin coatings resulted in a lower value (brightness) (4.89) than starch (5.44) and without coatings (5.33), but chroma (color density) was not affected by the type of coating with chroma values ​​ranging from 7.56 up to 8.44. Increasing the concentration of coated annatto pigment by 4% decreased the value of coral crackers, but the addition of both coated and uncoated annatto pigment concentrations was not able to increase chroma.
