Pengaplikasian Smart Packaging Ekstrak Mawar dan Lengkuas Merah Mendeteksi Kesegaran Udang pada Suhu Ruang: Smart Packaging Application of Rose Flower Extract and Red Galangal to Detect Shrimp Freshness at Room Temperature

Abstract

Shrimp are rich in protein and play a crucial role in meeting community nutritional needs. However, the high protein content also provides an ideal environment for microorganisms to grow, potentially decreasing shrimp quality and making it unsafe for consumption. To mitigate this risk, shrimp are stored and packaged with freshness indicators so that consumers can easily assess the quality of the shrimp. This study aims to evaluate the effect of using red rose and red galangal extracts in smart packaging on shrimp freshness, focusing on pH, organoleptic properties, and color. The indicator film uses ganyong starch with varying concentrations of red rose (14%, 16%, and 18%) and red galangal (1% and 2%). The study tested mean RGB values, weight loss, pH, and color using a Completely Randomized Design (CRD) with three repetitions. The tests were conducted at room temperature of approximately 25°C for 3x12 hours. The results show that red rose and red galangal can be used for indicator film labels in smart packaging because they provide color changes corresponding to pH increases in sea shrimp. Additionally, the weight loss of the shrimp continued to increase with the duration of storage, and the pH value also rose during storage conditions.
