Abstract

Each processing palm fresh fruit bunches (FFB) into Crude Palm Oil (CPO) will produce solid and liquid waste. One of the forms of liquid waste produced is Palm Oil Mill Effluent (POME). POME waste can cause problems for the environment because it has physical characteristics of dark brown color, high density, rich in organic matter, and bad smell. The POME waste color is thought to come from melanoidin, a biopolymer pigment produced by the Maillard reaction of coconut processing. Apart from melanoidin, phenolic components are detected in POME waste, where this group of compounds is toxic. Several studies have shown that Lactobacillus plantarum can reduce the color of POME by 75%. The decolorization process is thought to involve an enzyme as a waste color-changing agent. However, the efficiency associated with these events has not been further investigated. There are three main methods of melanoidin degradation, such as biological, physicochemical, and enzymatic. This study uses the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyzes) approach in creating a short, concise, and clear summary through various references.

Abstract

Tannins are one of the main compounds in plants with potential health benefits. Gallotannin is one of the biologically active tannins groups produced by some medicinal plants. Gallotannins is a hydrolyzable tannin compound biosynthesized through gallic acid, shikimic acid, and pentagalloylglucose pathways. Gallotannins can be separated by cascade solvent extraction procedures, column chromatography, and preparative HPLC. This review focuses on the discussion of biosynthesis and structure-activity relationship of tannins as antibacterial and anti-inflammatory. The structure-activity relationship (SAR) and biological activity of gallotannins is caused by the molecular bonds between gallotannins and certain other compounds, especially proteins, which make complex compounds, change physiological and morphological processes in bacterial cells or tissues. The biological activities of gallotannin include anti-inflammatory, anticancer or antitumour, antiviral, antioxidant, antibacterial, and antidiabetic. This review used the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) method approach in a short, concise, and clear summary about tannins through various references. Keywords: Biological activities, Biosynthesis, Gallotannins
