Tannins are naturally occurring polyphenolic compounds found in various plants, contributing to the astringency, color, and flavor of foods and beverages like wine and tea. They play a crucial role in plant defense mechanisms and have applications in leather production, medicine, and food preservation due to their antioxidant and antimicrobial properties.

Plant defense mechanisms are a series of structural, chemical, and molecular strategies that plants use to protect themselves from herbivores and pathogens. These defenses can be constitutive, always present, or induced, activated in response to an attack, ensuring the plant's survival and reproduction in a hostile environment.

Medicine is the science and practice of diagnosing, treating, and preventing disease, aimed at improving and maintaining human health. It encompasses a wide range of healthcare practices evolved to restore health by the prevention and treatment of illness, employing pharmaceuticals, surgery, therapy, and other interventions.

Food preservation involves techniques and processes that slow down the spoilage and decay of food, extending its shelf life while maintaining nutritional value, texture, and flavor. This is achieved through methods that inhibit the growth of microorganisms, reduce enzymatic activity, and prevent oxidation.

Food Preservation

Antioxidant properties refer to the ability of certain compounds to neutralize free radicals, which are unstable molecules that can cause cellular damage and contribute to aging and diseases such as cancer. These properties are crucial for maintaining cellular health and are found in various vitamins and phytochemicals present in fruits, vegetables, and other foods.

Antioxidant Properties

Antimicrobial properties refer to the ability of a substance to kill or inhibit the growth of microorganisms such as bacteria, fungi, and viruses. These properties are crucial in preventing infections and are utilized in various applications, including medicine, food preservation, and sanitation.
