Pendugaan Umur Simpan Minuman Teh Lemon Ready-To-Drink Dengan Metode Accelerated Shelf-Life Testing Model Arrhenius

Abstract

Dalam menghadapi dinamika lingkungan bisnis produk pangan, pengembangan produk minuman ready-to-drink (RTD) menjadi salah satu alternatif produk yang cukup prospektif. Minuman RTD ini memberikan kenyamanan dan kemudahan dalam pemrosesan, pengemasan, distribusi, pemasaran, hingga pada tahap konsumsi. Salah satu produk yang dikembangkan oleh Teaching Industry adalah minuman teh lemon dalam kemasan RTD yang wajib mencantumkan tanggal kedaluwarsa berdasarkan peraturan BPOM Nomor 31 Tahun 2018, sehingga perlu dilakukan pendugaan umur simpannya. Penelitian ini bertujuan untuk menduga umur simpan minuman teh lemon RTD menggunakan metode Accelerated Shelf-Life Testing model Arrhenius. Produk teh lemon RTD disimpan pada suhu 35 oC, 40 oC, dan 45 oC serta dianalisis secara berkala selama 35 hari. Parameter mutu yang diamati mencakup analisis objektif berupa pH, kekeruhan, dan warna; serta analisis subjektif berupa analisis organoleptik metode Quantitative Descriptive Analysis meliputi atribut aroma lemon, aroma manis, aroma teh, rasa asam, rasa manis, dan rasa sepat. Selain itu, dilakukan juga analisis terhadap total kapang dan khamir. Perhitungan umur simpan produk teh lemon RTD menghasilkan umur simpan selama 2 bulan 8 hari pada suhu penyimpanan 25 oC berdasarkan penerimaan organoleptik parameter rasa sepat.

In response to the dynamics of the food product business environment, developing ready-to-drink (RTD) beverages has emerged as a promising product alternative. These RTD beverages offer convenience and efficiency accross processing, packaging, distribution, marketing, and consumption stages. One of the products developed by Teaching Industry is RTD lemon tea, which adheres to the requirement stipulated by BPOM Number 31 of 2018 to display an expiration date, necessitating the determination of its shelf life. This study aims to estimate the shelf-life of RTD lemon tea using Accelerated Shelf-Life Testing method of the Arrhenius model. The lemon tea product was stored at temperatures of 35 °C, 40 °C, and 45 °C and subjected to periodic analyses over a duration of 35 days. The quality parameters observed include objective analysis such as pH, turbidity, and color; as well as subjective analysis such as organoleptic analysis using Quantitative Descriptive Analysis method covering attributes of lemon aroma, sweet aroma, tea aroma, sour taste, sweet taste, and astringent taste. In addition, an analysis of the total mold and yeast was also conducted. The shelf-life calculation of RTD lemon tea product resulted a shelf-life of 2 months and 8 days at 25 °C based on the organoleptic acceptance of astringent taste parameter.
