Abstract

Green tea is widely known as a beverage rich in antioxidants with numerous health benefits. However, excessive consumption may have negative effects, particularly on gut health. This article discusses the impact of excessive green tea consumption on stomach irritation, mineral absorption disruption, gut microbiota imbalance, and caffeine-related side effects. It concludes that moderate consumption of green tea (2-3 cups per day) is safe and beneficial. Proper consumption management can maximize green tea benefits without adverse effects on gut health.

Abstract

This study aims to examine the role of biochemistry in the processing of functional foods and its impact on the nutritional content and bioactive compounds. The method used is a literature review, collecting and analyzing relevant literature on biochemistry, food processing, and functional foods. The results show that biochemical processes, such as fermentation and heating, can affect the nutritional content of food. Fermentation can increase the content of probiotics and unsaturated fatty acids that are beneficial for health, while excessive heating can damage sensitive compounds like vitamin C. Proper processing can enhance the bioavailability of bioactive compounds, thus optimizing the health benefits of functional foods. The conclusion of this study emphasizes the importance of understanding biochemical processes in food processing to maximize health benefits.

Abstract

Microscopic staining is an important technique in observing plant tissue to increase contrast and clarify cellular structures. One of the dyes commonly used in plant tissue studies is Safranin, a cationic base compound from the azo group that has a high affinity for cell components that produce negative impacts such as lignin and nucleic acids. This study aims to determine the effectiveness of Safranin as an alternative dye in microscopic observation of spinach leaf tissue (Amaranthus spp.). The practicum was carried out using the wet preparation method, using cross-sections of spinach leaves stained with Safranin solution, then observed under a light microscope. The results showed that Safranin was able to provide good red color contrast to cell walls, cell nuclei, and blood vessel tissue, so that structures such as epidermis, palisade tissue, sponges, and xylem and phloem could be clearly identified. However, obstacles arise in the regulation of concentration and duration of staining, where excess of both can cause excess and excessive structural accuracy. Therefore, adjustment of technical parameters is needed to obtain optimal results. These findings indicate that Safranin is effective as a microscopic dye and has the potential to be used in educational practicum activities, because it is economical, safe, and easy to apply. This study also applies the interdisciplinary application of chemistry and biology in science learning.

Abstract

This study aims to observe the phases of mitosis in the meristem cells of shallot roots (Allium cepa) through microscopic observation as part of the Cell Biology learning model. Mitosis is an important part of the cell cycle that plays a role in growth, tissue repair, and asexual reproduction in organisms. A deep understanding of the mitosis process is an important foundation in various branches of biology, including genetics, biotechnology, and histology. Shallot roots were chosen because they have actively dividing meristem tissue at the root tip,as well as a large and transparent cell structure that facilitates the staining and observation process. Preparation was carried out by soaking the onion roots in a solution of acetic acid and alcohol for fixation,then staining with acetocarmine acid so that the chromosomes are clearly visible. The process of crushing the root tip and pressing it on a glass object (squash method) was used to expand the observation area. A light microscope with a magnification of 400x and 1000x was used to identify the division phases. Observation results show the presence of all phases of mitosis, namely prophase (nucleolus and nuclear membrane begin to disappear,chromosomes condense), metaphase (chromosomes line up at the equator), anaphase (chromatids separate to opposite poles), and telophase (nuclear membrane and two daughter cell nuclei re-form). Visual documentation in the form of microscopic photographs and descriptive tables clarify the identification of these phases, thus facilitating student understanding.From a pedagogical perspective, this microscopic practicum-based learning has been proven to improve students' observational skills, laboratory skills, and conceptual understanding of cell division. Students not only memorize theories, but directly experience the scientific process through exploration and discussion of observation results. Evaluation of learning outcomes is carried out through post-practicum quizzes and student worksheets, showing an increase in understanding scores of more than 30%.
