Abstract

The aim of this research was to determine the best extraction temperature and concentration of citric acid in the extraction of betacyanin powder from Dentata Ruby leaves (Alternanthera dentata) and to know organoleptic panelist reception in the application of betacyanin pigment as a natural colourant to several food types. The design used in this research is Factorial Random Design (RAL) with 2 factors and 3 replications. The data obtained were analyzed statistically by F test, then if significant effect was continued with HSD-Tukey test at 5% real level. The extraction temperature factor consisting of 2 levels ie cold temperature (8oC) and room temperature (25oC), and the citric acid concentration factor consisting of 4 levels ie 0%, 1%, 3% and 5%. The results showed that the interaction between extraction temperature and citric acid concentration in the extraction process gave significantly different effect on betacyanin concentration, acidity degree (pH), total acid and powder yield. The extract of betacyanin pigment powder extracted at room temperature (25oC) with the addition of 0% citric acid was the best treatment with betacyanin concentration of 214.47 mg / 100 g of material, pH 5.85 and total acid of 1.272% and powder yield of 56.43 %. The application of betacyanin powder extract on jelly, syrup and ice cream can be accepted organoleptically by the best treatment that is the addition at 1.5%concentration. Key words: antioxidants, betacyanin, dentata ruby, colourant ABSTRAK Penelitian ini bertujuan untuk menentukan suhu ekstraksi dan konsentrasi asam sitrat terbaik pada ekstraksi pigmen betacyanin daun kremah merah (Alternanthera dentata) dan mengetahui penerimaan panelis secara organoleptik terhadap aplikasi pigmen betacyanin sebagai pewarna alami terhadap beberapa jenis pangan. Rancangan yang digunakan dalam penelitian ini adalah Rancangan Acak Lengkap (RAL) faktorial dengan 2 faktor dan 3 kali ulangan. Data yang diperoleh dianalisa secara statistik dengan uji F, kemudian bila berpengaruh nyata dilanjutkan dengan uji HSD-Tukey pada taraf nyata 5%. Faktor suhu ekstraksi yang terdiri dari 2 taraf yaitu suhu dingin ( 8oC) dan suhu kamar (25oC), sedangkan faktor konsentrasi asam sitrat yang terdiri dari 4 taraf yaitu 0 %, 1%, 3% dan 5%. Hasil penelitian menunjukkan interaksi antara suhu ekstraksi dan konsentrasi asam sitrat pada proses ekstraksi memberikan pengaruh yang berbeda nyata terhadap konsentrasi betacyanin, derajat keasaman (pH) dan total asam serta rendemen bubuk. Ekstrak bubuk pigmen betacyanin yang diekstraksi pada suhu kamar (25oC) dengan penambahan asam sitrat 0 % merupakan perlakuan terbaik dengan karakteristik konsentrasi betacyanin sebesar 214,47 mg/100 g bahan, pH 5,85 dan total asam 1,272 % serta rendemen bubuk 56,43 %. Aplikasi penambahan ekstrak bubuk pigmen betacyanin pada jelly, sirup dan es krim dapat diterima secara organoleptik dengan perlakuan terbaik yaitu penambahan pada konsentrasi 1,5 %. Kata kunci: antioksidan, betacyanin, kremah merah, pewarna.

Abstract

Instant spice drinks that function to maintain body stability and are believed to be able to increase the body's immunity are developing very rapidly in the era of the Covid-19 pandemic. Ginger is a spice with various benefits, providing opportunities for the Small Business industry. One of them is the instant spice drink industry player "Instant Red Ginger Ar-ridhwan" which produces natural instant spice drinks. However, the processing of instant spice drinks still needs to be improved. In this case, appropriate technology is urgently required to speed up the production process. The purpose of this activity is to introduce technology in the production of instant spice drinks to produce products with more guaranteed quality and to be able to generate additional income for partners through the optimization of processing. The service begins with identification, planning, trial production of instant spice drinks, and evaluation. The stages of implementing this activity are socialization, demonstration/training, and evaluation. The results of the activities that have been carried out show new knowledge for partners in carrying out alternative applications of ginger processing technology, especially in the ginger squeezing process. The spinner tool can shorten ginger's pressing time compared to using the previous press tool. The application of appropriate technology in the production of instant spice drinks needs to be carried out thoroughly at every stage of the processing process to be able to increase the maximum quality and quantity, and product testing is required to produce products with more guaranteed quality and be able to generate additional income for partners and the community.
