Abstract

One way to extend shelf life and maintain the quality of fresh chicken meat is to implement an active packaging system. This research aimed to develop active packaging in the form of pads used in chicken meat with dual functions: Super Water Absorbent (SWA) as an adsorbent system and Ethanol Emitter (EE) as an antibacterial release system. The packaging in this study was first carried out by making SWA/EE with a ratio of 0, 4, and 2 (b/v). Furthermore, SWA/EE granules were inserted into non-woven PP bags to form an adsorbent active packaging pad. The experimental design used was a Randomized Group Design (RGD) with 2 factors, namely SWA/EE pad ratio 0, 4, and 2 (b/v) with non-pad as control and storage time (0, 1, 3, 5, and 7 days). Each treatment was repeated 3 times. The results showed that the SWA/EE ratio 4 (w/v) had better ethanol release and water absorption rate compared to other treatments. SWA/EE treatment with SWA/EE ratio of 4 (b/v) showed a significant difference on the anti-bacterial activity of S. aureus (34.58 mm) and total bacterial growth on storage days 3, 5, and 7, with the lowest value on day 3 (1.52 log CFU/g). SWA/EE treatment did not significantly different on the antibacterial activity of E. coli and total bacterial growth at day 1 storage. Packaging with an SWA-EE ratio of 4 (w/v) has the potential to be a double active packaging that can be used on fresh chicken meat.

Abstract

Gudeg, a traditional Indonesian dish, is highly susceptible to microbial spoilage. Irradiation technology can be utilized to extend the shelf life of gudeg while preserving its nutritional value. However, the effects of gamma irradiation on the bacterial abundance in food products have not been widely researched. This study investigated how gamma irradiation influences its bacterial community. Vacuum-packed gudeg was gamma-irradiated in a frozen condition at a dose of 20 kGy, with a dose uniformity ratio (DUR) of 1.08. The resulting microbiome was characterized via 16S rRNA sequencing, using non-irradiated gudeg as a comparison. Gudeg samples were then amplified using the standard 16S rRNA V3-V4 primers. After taxonomic classification, alpha diversity indices—Shannon, Margalef, Chao1, and ACE—were applied to compare species richness and evenness in irradiated and non-irradiated samples. The research results showed that irradiation substantially reduced Proteobacteria, particularly staphylococcal species, while preserving beneficial lactic acid bacteria, such as Weissella sp. The overall diversity slightly decreased, but pathogenic risks diminished, indicating extended shelf stability. These findings suggest gamma irradiation as an effective strategy to enhance gudeg's safety and longevity. Furthermore, they offer insights into broader applications of irradiation for preserving high-moisture, ready-to-eat foods and indicate that sustainable research into the effects of irradiation on spoilage microbes and specific pathogens in various traditional food products is possible.
