Abstract

Weeds are plants that live wild on cultivated land, which can reduce the productivity of cultivated plants. Phytochemical content in weeds has various benefits besides food, such as vegetable pesticides, pharmaceuticals, industry, and cosmetics. For this reason, this research aims to analyze the content of secondary metabolite compounds and measure the levels of allelopathic phytochemical compounds in several weed plants. Various substances have been identified in the form of allelopathy, namely flavonoids, tannins, phenolic acids, ferulic acid, coumarins, terpenoids, steroids, cyanohydrins, quinones, cinnamic acid, and their derivatives. Compounds identified as allelochemical compounds are flavonoids, tannins, phenolic acids, ferulic acid, coumarins, steroids, terpenoids, cinnamic acids, and their derivatives. Exploratory methods to identify plant types, experimental methods with phytochemical screening tests to characterize types of secondary metabolite compounds, and allelopathic toxicity tests Based on the results and discussion that have been presented, it can be concluded that the weeds Echinochloa crus-galli, Panikum repen, Euphorbia hirta, Ageratum conyzoides, and Imperata cindrica contain flavonoid, tannin, and phenol compounds. The weeds with the highest scores in the phytochemical test are Echinochloa crusgalli and Ageratum conyzoides.

Abstract

Acrylamide, a potentially carcinogenic compound, forms during high-temperature food processing and has garnered significant attention in the coffee industry due to its implications for public health and food safety. This study analyzes research trends on acrylamide formation and mitigation in coffee processing over the past decade, utilizing bibliometric methods and VOSviewer software. A dataset of publications from 2014 to 2024 was examined to uncover key research themes, leading contributors, and collaborative networks in the field. The analysis reveals a growing body of research focused on understanding the mechanisms of acrylamide formation, developing mitigation strategies, and balancing quality preservation with regulatory compliance. Emerging trends, such as metabolomic approaches and advanced roasting techniques, highlight a shift towards more targeted and sustainable solutions. Additionally, the findings emphasize notable international collaborations, though further interdisciplinary research is needed to address existing gaps and enhance practical applications. This bibliometric study provides valuable insights into the scientific landscape of acrylamide research in coffee processing, offering a foundation for future studies and innovations aimed at ensuring food safety while maintaining coffee quality.
