Safety and quality, as the major concerns of meat, are highly dependent on the ingredients and packaging techniques used. A basic combination of active and intelligent packaging is believed to be capable of preserving product quality, extending shelf life, and monitoring product deterioration. Therefore, this study aimed to extend and monitor the beef quality at cold temperatures (4 ± 1 °C). The active packaging applied garlic extract (0%, 15%, and 20% (w/w)) to release anti-microbial agents. Meanwhile, the intelligent paper applied a combination of bromothymol blue (BTB) and phenol red (PR) solutions at pH 5.00. The results showed that beef packed without the addition of garlic extract had already deteriorated on the 6th day of storage while, and with the addition of garlic extract (15% and 20%) rotted on the 12th day. The intelligent indication label’s color profile changed from dark yellow (fresh), to reddish-yellow (to be consumed immediately), to faded red (rotten). The color change of the intelligent indicator label in response to all meat deterioration criteria demonstrates a linear correlation for determining the extent of rottenness during storage. Therefore, this simple combination of active paper and intelligent indicator can be used to extend the shelf life and monitor meat quality.
Traditional food is a heritage of a country and therefore brings pride to a country or region. A bibliometric analysis of traditional Indonesian food was conducted in this paper to see the trend over the last decade, analyze thecontribution of countries, and analyze the most frequently used keywords. A total of 102 documents were gathered from 66 different sources, including 57 articles, 36 conference papers, 4 reviews, 4 book chapters, and 1 data paper. According to this review, Indonesia is the most productive country in terms of producing articles (92) in this field, as well as having the most citations (315), despite having the lowest average number of citations perarticle. Surya R was the most productive author, with four documents, and Nuraida L had the most citations, with 111. Tempeh was also the most frequently used keyword, with 13 occurrences. It was hoped that this overview would help to advance research in traditional Indonesian food.
Perishable food really needs proper handling. Therefore, various industries and researchers continue to innovate, especially in the development of packaging. The development of active packaging is a new innovation in the field of packaging technology. This packaging innovation was designed to maintain the quality of packaged food. This study aimed to obtain the best concentration of antimicrobial garlic ingredients with a mixture of paper as an active packaging material. The concentration of garlic extract used in this study was 0%, 5%, 10%, and 15%. Based on the result obtained, it could be concluded that the active paper with the addition of garlic extract concentration of 15% had the best effectiveness then followed by concentrations of 10%, 5%, and 0%. The effectiveness could be seen from the diameter of inhibition zone formation resulted.
In recent years, much attention has been paid to the use of biopolymers as food packaging materials due to their important characteristics and properties. These include non-toxicity, ease of availability, biocompatibility, and biodegradability, indicating their potential as an alternative to conventional plastic packaging that has long been under environmental scrutiny. Given the current focus on sustainable development, it is imperative to develop studies on biopolymers as eco-friendly and sustainable food packaging materials. Therefore, the aim of this review is to explore trends and characteristics of biopolymer-based biodegradable films for food packaging, analyze the contribution of various journals and cooperation between countries, highlight the most influential authors and articles, and provide an overview of the social, environmental, and economic aspects of biodegradable films for food packaging. To achieve this goal, a bibliometric analysis and systematic review based on the PRISMA method were conducted. Relevant articles were carefully selected from the Scopus database. A bibliometric analysis was also conducted to discuss holistically, comprehensively, and objectively biodegradable films for food packaging. An increasing interest was found in this study, especially in the last 3 years with Brazil and China leading the number of papers on biodegradable films for food packaging, which were responsible for 20.4% and 12.5% of the published papers, respectively. The results of the keyword analysis based on the period revealed that the addition of bioactive compounds into packaging films is very promising because it can increase the quality and safety of packaged food. These results reveal that biodegradable films demonstrate a positive and promising trend as food packaging materials that are environmentally friendly and promote sustainability.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
