“…Green and purple samples result in the best color separations, probably because yellow and red components are strongly retarded by corn starch. Starch is a polysaccharide with a combination of maltose units, containing many hydrophilic groups . Yellow and red should be the more polar components in the samples.…”

In light of the COVID-19 pandemic situation, the separation of the primary colors of ink markers and food coloring was performed using a simplified column chromatography setup at home to accomplish the educational outcome of the course. The virtual class instruction, for the students enrolled in the Organic Techniques Laboratory course, allows the understanding of the basic principles of chromatography in a way similar to that in the face-to-face experience. The materials proposed for conducting the experiment are readily available at home or easily found in a drugstore or in a grocery store. A wide variety of results were observed where the separation of at least two primary colors was achieved by 80% of the students.

“…However, there are methods that facilitate the isolation of pigments after extraction and before purification/characterization of chlorophyll. These preparatory methods are thin-layer chromatography or column chromatography, which reduce time and effectively separate the chlorophyll [238,242].…”

Red Seaweed Pigments from a Biotechnological Perspective

Algae taxa are notably diverse regarding pigment diversity and composition, red seaweeds (Rhodophyta) being a valuable source of phycobiliproteins (phycoerythrins, phycocyanin, and allophycocyanin), carotenes (carotenoids and xanthophylls), and chlorophyll a. These pigments have a considerable biotechnological potential, which has been translated into several registered patents and commercial applications. However, challenges remain regarding the optimization and subsequent scale-up of extraction and purification methodologies, especially when considering the quality and quantity needs, from an industrial and commercial point of view. This review aims to provide the state-of-the-art information on each of the aforementioned groups of pigments that can be found within Rhodophyta. An outline of the chemical biodiversity within pigment groups, current extraction and purification methodologies and challenges, and an overview of commercially available products and registered patents, will be provided. Thus, the current biotechnological applications of red seaweeds pigments will be highlighted, from a sustainable and economical perspective, as well as their integration in the Blue Economy.

“…Preservice teachers (tertiary education-pedagogical studies) were addressed in nine articles. Some of these articles described examples of the integration of green chemistry experimental work [39,83,[92][93][94][95][96][97], whereas others evaluated activities for integration of green chemistry into experimental work [95,97,98]. The incorporation of green chemistry experiments into the education of pre-service teachers was recognized as a way to promote the development of students' pro-environmental attitudes, values, knowledge, and motivation [39,[95][96][97].…”

Experimental work is an important component of science subjects at all educational levels. The implication of green chemistry ideas indicated the need for optimization of traditional experimental work by implementing green chemistry principles to promote sustainable development. The aim of the study is to present findings from a systematic literature review on the use of experimental work in science education from green chemistry perspectives in the literature from 1995 to 2020. Thus, three electronic databases were reviewed following the Preferred Reporting Items for Systematic Reviews (PRISMA) guidelines. The literature search identified a total of 1199 papers from Web of Science (N = 419), Scopus (N = 578), and Education Resources Information Center (ERIC) (N = 202). After applying inclusion/exclusion criteria, 263 papers were obtained and then analyzed in further detail. The findings highlighted trends in the integration of green chemistry principles into experimental work from primary to tertiary education levels and identified a literature gap, as well as the challenges and the possibilities for future development. The review outlined various opportunities for active learning within experimental work from green chemistry perspectives using a range of methods, with a particular focus on practical, hands-on, and laboratory activities.
