Abstract

Katekin merupakan senyawa bioaktif dengan kerangka flavan-3-ol dan menjadi senyawa utama penentu mutu serta dapat memberikan rasa pahit yang khas pada teh. Senyawa turunan katekin yang memiliki aktivitas sebagai antioksidan paling kuat dan melimpah yaitu epigalokatekin galat. Tujuan dari review artikel ini yaitu untuk mengetahui kandungan senyawa katekin dan epigalokatekin galat sebagai antioksidan pada berbagai jenis teh berdasarkan nilai IC50.Metode penulisan review artikel ini dilakukan dengan mencari serta menganalisis studi pustaka dari beberapa jurnal yang berkaitan dengan aktivitas antioksidan pada berbagai jenis teh dengan penelusuran terhadap senyawa katekin, khususnya epigalokatekin galat. Hasil review menunjukkan bahwa aktivitas antioksidan pada pengolahan jenis teh seperti teh hijau, teh oolong, dan teh hitam memiliki perbedaan yang cukup signifikan yang dapat dilihat dari kandungan senyawa katekin dan EGCG dimana semakin besar kandungan senyawa tersebut, maka aktivitas antioksidannya semakin tinggi. Selain itu, tingginya aktivitas antioksidan dapat dilihat dari nilai IC50. Semakin rendah nilai IC50, maka aktifitas antioksidan akan semakin tinggi. Teh hijau terbukti memiliki aktivitas antioksidan yang paling tinggi diantara teh lainnya dengan kandungan katekin sebesar 10,04% dan epigalokatekin galat sebesar 3,28% serta nilai IC50 yang paling rendah yaitu 58,61 µg/mL. Kata Kunci: Katekin, Teh Hijau, Teh Oolong, Teh Hitam, Antioksidan Catechins are bioactive compounds with a flavan-3-ol structure and become a major determinant of quality compounds and can give a distinctive bitter taste of tea. Catechin derivative compounds that have the antioxidant activity as the strongest and abundant are epigallocatechin gallate. The purpose of this article review was to determine the content of catechins and epigallocatechin gallate compounds as an antioxidant in various types of tea based on the IC50 value. The method of writing of this article review was carried out by searching and analyzing literature studies from several journals related to antioxidant activity in various types of tea by tracing catechin compounds, especially the epigallocatechin gallate. The results of the review showed that the antioxidant activity in the processing of types of tea such as green tea, oolong tea, and black tea has significant differences which could be seen from the content of catechins and EGCG compounds where the greater the content of the compounds, the higher the antioxidant activity. Also, the high antioxidant activity can be seen from the IC50 value. The lower the IC50 value, the higher the antioxidant activity. Green tea shows to have the highest antioxidant activity among other teas with a catechin content of 10.04% and an epigallocatechin gallate of 3.28% and the lowest IC50 value of 58.61 µg/mL.

Abstract

The porang plant (Amorphophallus Muelleri) is one of the forest plants in Indonesia with fairly high productivity. Porang tubers contain water-soluble polysaccharides in the form of glucomannan. Glucomannan is a dietary fibre that is soluble in water. The relatively high content of glucomannan makes the porang plant a useful plant, one of which is in the fields of food and health. This journal review aims to examine the use of porang-derived products in the food and health sectors. Journal writing is done by collecting data from various sources obtained from several research journals on the internet such as Google Scholar and DOAJ. Based on the results of the journal review, it can be concluded that porang plants can be used to influence texture in the manufacture of food products such as food bars, white bread, noodles, meatballs, sausages, nuggets, and gelling agents. In addition, the porang plant can be used in the health sector as an ingredient for making capsule shells and emulsion stabilizers, which are used as an alternative diet for people with obesity and type 2 diabetes mellitus.
