Abstract

Technological developments in the food preservation process are increasingly advanced, including the use of coconut shell smoke into liquid smoke which is used as a natural food preservative. The use of liquid smoke as a preservative in powder form is more efficient in the process of preserving food products. One of the preserved food ingredients is beef. The purpose of this study was to determine the manufacturing process and characteristics of smoked powder and to analyze the effect of using smoked powder on the quality of beef. This research was compiled based on a completely randomized design (CRD), making powdered liquid smoke with 4 variations consisting of 2 factors, namely maltodextrin (25 and 50 grams) and chitosan (25 and 50 grams) with 3 replications. Research data were analyzed using the ANOVA test, Kruskal-Wallis test, and Mann-Whitney test. Variables measured: characteristics of liquid smoke powder (weight, pH, total acid, moisture content, and color), Total Plate Count (TPC) on the beef and beef organoleptic test (color, smell, and texture). The results showed that from the characteristics of the liquid smoke powder, a good variation of powder was found, namely variation 1, with a ratio of 50:25 grams of encapsulation usage. The results of the total bacteria count (TPC) showed that with the addition of smoked powder variation 1 (50:25), the growth of bacteria in beef was two times slower than without the addition of smoked powder. The results of organoleptic test of beef with the addition of smoked powder are redder in color, the texture is harder and the smell is less pungent than without the addition of smoked powder, the color is pale red, the texture is soft and the smell is pungent.

Abstract

Bibliometric analysis is a crucial way to understand trends and progress in a field of research. Using the VOSviewer application for bibliometric analysis becomes an effective tool to demonstrate research patterns, networking, and research focus. This study explains the analysis of scientific publications related to rotary dryers using the VOSviewer application. This study aims to find trends through analyzing bibliometric data on rotary dryer research for 10 years (2014–2023). Data was collected from the Scopus database. The method used is descriptive causality, using VOSviewer to visualize relationships between keywords, authors, institutions, countries, and network collaborations between authors. The study showed 1,356 articles relevant to rotary dryers between 2014 and 2023. After elimination by document type (article, conference paper, review, and conference review) and language type (English), 465 articles were obtained. The bibliometric analysis results show changes in research trends, from performance studies to the study of the use of energy resources in rotary dryers and their integration with intelligent systems. There are five keyword clusters, with primary keywords in each cluster. The number of articles on the topic of rotary dryers has increased from year to year, with China being the country with the most publications and citations. Still, the number of links and strength of the author's relationship with other countries in carrying out joint publications remain relatively low. The results of this bibliometric analysis provide a helpful overview of research progress and prospects with the topic of rotary dryers and help the authors plan further research.
