Volatile compounds are one of the important characteristics of vinegar, where the content and composition of these compounds is an account for the aroma profile of vinegar. The difference in production technology used in making vinegar produces vinegar with different characteristics. There are two general methods commonly used in the production of vinegar, namely the slow method and the fast method. This meta-analysis was used to conclude several studies that examined the differences in volatile compounds in vinegar produced through the slow methods and the fast methods. From this study, it can be seen that comparison of volatile compounds characteristics in vinegar produced by the slow method and the fast method where the slow method tends to produce vinegar with a high concentration of acetate ester group and alcohol group, and the fast method tend to produce vinegar with a high concentration in a volatile acid group.

The study aimed to explore the influence of fermentation and non-fermentation on cocoa processing (Theobroma cacao L.) on physical properties, chemical properties, fatty acid profiles and sensory properties of cococa butter. The study was conducted using an experimental method with two treatments and three replications. Analysis of cocoa butter consisted of yield, color, moisture content, free fatty acids, iod numbers, peroxide numbers, determination of fatty acid profile using GC-MS, and analysis of sensory properties. The results showed that the yield was between 20.82-21.00%. The color of fermented cocoa butter has a value of L* 17.88, a*8.70, and b*7.99 while for nonfermented cocoa butter has a value of L* 14.88, a* 8.96, and b* 6.78, water content between 0.10-0.12%, free fatty acids 0.51-0.56%, iod numbers 26.40-26.50 g I2/100g, peroxide numbers between 0.40-0.70 meq peroxide/kg fat, 190.23-191.40 mg KOH/g fat. The fatty acid profile using GC-MS showed that the dominant fatty acid constituents contained in fermented and nonfermented cocoa fats are oleic acid (29.39-29.57%), heptadecanoic acid (25.85-26.77%), and palmitic acid (21.49-21.83%). Based on sensory analysis of cocoa butter with fermented treatment is preferred because it has a more attractive color, taste, and aroma compared to nonfermented cocoa butter.

Purpose: This work aimed to analyze the profiles of amino acids in the ficin enzyme isolated from Ficus aurata (Miq.), and to determine the efficiency of these amino acid concentrations under two types of drying – solar drying and freeze drying. Methodology: The enzyme ficin was obtained from fig tree, and the presence of amino acids was determined by UPL chromatography. The applied methods of drying were solar and freeze. However, the primary objectives were aimed at investigating the influence of these treatments on the level of amino acids present in all the samples. Results: The findings indicated that freeze drying techniques retained more amino acids in figs than was observed in the case of solar drying. In particular, the amount of L-glutamic acid in freeze drying was 2.39 mg/g, while that of solar drying was 1.43 mg/g. Similar results were observed in L-lysine and L-aspartic acid, which were relatively higher in freeze drying than solar drying, with concentrations of 2.43 mg/g and 2.55 mg/g, respectively, as opposed to 0.99 mg/g and 1.76 mg/g in solar drying. Besides, freeze drying showed better L-serine, L-phenylalanine, and L-histidine preservation. Findings: It was observed that freeze drying gave the best opportunity to reduce the loss of amino acid of the ficin enzyme. The drying method, in particular, resulted in a concentration of some important amino acids like L-glutamic acid, L-lysine, L-aspartic acid, L-serine and L-phenylalanine, and L-histidine as compared to solar drying. Novelty: This study focused on different types of solar energy and freeze energy economic systems in enzymatic activities in the ficin enzyme extracted from Ficus aurata (Miq.). The novel contribution of this research lies in its objective, which is to show how the drying methods used affected the retention of the most influential and critical amino acids in the enzymatic processes. Originality: The novel aspect of the study was the attachment of ultra vortices to different drying techniques, such as solar drying and freeze drying in select ficin enzymes from Ficus aurata. It opens up a new perspective toward the development of drying parameters for the enhancement of important enzymatic characters from this particular variety. Conclusion: This research considers the changes in amino acid content during the drying of ficin enzyme from Ficus aurata through different drying methods. It is shown that freeze drying enhances the retention of critical amino acids and is thus one of the most efficient methods for the enzymatic processing of this plant species. Type of Paper: Empirical research paper.
