Abstract

The Roselle petals contain anthocyanin pigment which functions as an antioxidant and a natural food colorant. The objective of this research was to study the effect of three enzymes: pectinase, cellulase, and glucoamylase, on the quality of the extract of the Roselle petals. The fresh and dried Roselle petals were extracted using distilled water in a ratio of 1:4 and divided into five parts, in which each part was added by pectinase (P) of 1000ppm; pectinase and cellulase (PC) of 500:500ppm; pectinase and glucoamylase (PG) of 500:500ppm; and pectinase, cellulase and glucoamylase (PCG) of 333:333:333ppm, and without enzyme (TE) as a control. Furthermore, 1% of citric acid was added to all treatments. Determination of the chosen treatment used was based on residue extract, anthocyanin analysis, and the pH value. The results showed that fresh Rosella extract with PC has a yield value of 7.60% and it was not significantly different from the extract with PCG which yielded 7.37%.  Dried Rosella extract with PCG had the highest yield of 22.10% compared to the control (without enzyme) of 12.96%. However, the PCG addition generated a sticky product. Both fresh and dried Roselle extracts with PC contained the highest anthocyanin content of 156.64±1.30mgL-1 and 35.09±0.04 mgL-1, respectively. The pH values of fresh and dried Roselle extracts were 2.65 and 2.24, respectively. This research showed that the treatment of fresh and dried Roselle petals with the addition of  P, PC, or PCG increased the extraction yield value. Additionally, these enzymes could also increase the anthocyanin content of the extracts.

Abstract

Sweet potato has great potency to be developed as an alternative carbohydrate source in the form of modified sweet potato flour. Autoclaving retrogradation is a physical modification method to improve the physicochemical characteristics of flour. The purpose of this study was to determine the effect of the autoclaving retrogradation method on the characteristics of various sweet potato flour: dietary fiber, resistant starch, starch digestibility, nutritional content, and antioxidant, and to determine the best modified sweet potato flour. The experimental design used a non-factorial completely randomized block design with four replications. The treatment consisted of 6 types of sweet potato, namely control (purple sweet potato without treatment), orange sweet potato, purple sweet potato, honey-sweet potato, red sweet potato, and purple white sweet potato). The results showed that there were significant differences in dietary fiber, levels of resistant starch, digestibility of starch, nutritional content, and antioxidant activity amongst various types of modified sweet potato flour. The best modified sweet potato flour was found in modified red sweet potato flour which contained 44.64% dietary fiber, 19.75% resistant starch, 13.50% starch digestibility, 66.32%  antioxidant activity, with comparable nutritional content.

Abstract

One form of honey adulteration is label adulteration for some premium honey such as uniflora honey from the honeybee species Trigona sp. One of the analytical methods that are currently developing and have the potential to perform the classification of premium honey in Indonesia is the UV spectroscopy method. In this study, an investigation was carried out on the effect of dilution on the performance of UV spectroscopy in the process of classifying Indonesian honey with different honeybees. A total of 4 types of honey samples with 10 samples each were used in this study. The honey sample was then diluted using distilled water. Each type of honey was given two dilution treatments, namely 1:20 (volume: volume) dilution of 5 samples and 1:40 (volume: volume) dilution of 5 samples. Spectral data were taken using a UV-visible spectrometer with a wavelength of 190-1100 nm (Genesys™ 10S UV-Vis, Thermo Scientific, USA) using the transmittance mode. The results of spectra analysis generally show that the sample with a 1:20 dilution has a higher absorbance intensity for both the original and modified spectra. The PCA results for each dilution showed that the honey samples could be separated into four different clusters for both 1:20 and 1:40 dilutions. The results of PCA analysis using all samples showed that the honey samples were classified into eight different clusters showing a significant effect of differences in honey sample dilution on the classification process of honey samples based on differences in the types of honeybees.
