Special Issue Information

Dear Colleagues,

Food preservation and packaging technologies play a pivotal role in determining the shelf life of fresh products. In the modern food industry, maintaining the quality, freshness, and safety of fresh produce, meats, dairy, and other perishable items is of utmost importance. This not only reduces food waste but also ensures that consumers have access to high-quality, nutritious food.

The development of innovative packaging materials and preservation techniques can significantly extend the shelf life of fresh products. These technologies help in controlling factors such as oxygen, moisture, microbial growth, and enzymatic activity, all of which contribute to the spoilage of fresh goods. For instance, modified atmosphere packaging can alter the gas composition around the product, while new-generation antimicrobial packaging materials can inhibit the growth of harmful microorganisms.

This Special Issue of Foods, titled “Food Packaging and Preservation Technologies for Improving Fresh Product Shelf Life”, invites contributions in the form of original research papers or reviews. The scope of this Special Issue includes, but is not limited to, the following aspects:

  1. Exploration of novel packaging materials, such as biodegradable, intelligent, and active packaging, and their impact on fresh product shelf life;
  2. Evaluation of emerging preservation technologies, like high-pressure processing, pulsed-electric field treatment, and non-thermal plasma, in maintaining fresh product quality;
  3. Understanding the interaction between packaging, preservation techniques, and the biochemical and microbiological characteristics of fresh products;
  4. Strategies for optimizing the combination of packaging and preservation methods to enhance the overall shelf life and marketability of fresh products.

This study proposes a novel non-destructive approach to assessing and predicting the quality of stored date fruits using a composite quality index (Qi) modeled via visible–near-infrared (VIS–NIR) spectroscopy and artificial neural networks (ANNs). Two leading cultivars, Sukkary and Khlass, were stored for 12 months using three temperature regimes (25 °C, 5 °C, and −18 °C) and five types of packaging. The samples were grouped into six moisture content categories (4.36–36.70% d.b.), and key physicochemical traits, namely moisture, pH, hardness, total soluble solids (TSSs), density, color, and microbial load, were used to construct a normalized, dimensionless Qi. Spectral data (410–990 nm) were preprocessed using second-derivative transformation and modeled using partial least squares regression (PLSR) and the ANNs. The ANNs outperformed PLSR, achieving the correlation coefficient (R2) values of up to 0.944 (Sukkary) and 0.927 (Khlass), with corresponding root mean square error of prediction (RMSEP) values of 0.042 and 0.049, and the relative error of prediction (REP < 5%). The best quality retention was observed in the dates stored at −18 °C in pressed semi-rigid plastic containers (PSSPCs), with minimal microbial growth and superior sensory scores. The second-order Qi model showed a significantly better fit (p < 0.05, AIC-reduced) over that of linear alternatives, capturing the nonlinear degradation patterns during storage. The proposed system enables real-time, non-invasive quality monitoring and could support automated decision-making in postharvest management, packaging selection, and shelf-life prediction.

Abstract
This study investigated the effect of cattle age on the color stability of Psoas major steaks under different packaging conditions, including polyvinyl chloride (PVC) film packaging, high-oxygen-modified atmosphere packaging (HiOx-MAP), and carbon monoxide-modified atmosphere packaging (CO-MAP), over a 14-day storage period.

This study investigated the effect of cattle age on the color stability of Psoas major steaks under different packaging conditions, including polyvinyl chloride (PVC) film packaging, high-oxygen-modified atmosphere packaging (HiOx-MAP), and carbon monoxide-modified atmosphere packaging (CO-MAP), over a 14-day storage period. Steaks from old cows had a greater myoglobin content than those from young animals (p < 0.05), resulting in a darker beef color. Regardless of animal age, steaks in PVC and HiOx-MAP exhibited poor color stability during storage, as evidenced by the low color intensity and high surface metmyoglobin (MetMb; p < 0.05). These samples also exhibited a reduced MetMb reducing activity (MRA) and oxygen consumption rate (OCR) and higher 2-thiobarbituric acid reactive substance (TBARS) levels, with these effects being evident in steaks from mature cows. In contrast, steaks stored in CO-MAP had greater redness, MRA, and OCR, along with lower surface MetMb and TBARS levels (p < 0.05), contributing to the limited discoloration of steaks from both age groups. These findings suggest that while both harvest age and packaging affect the shelf stability of bovine steaks, packaging plays a more significant role. CO-MAP proved to be more effective than aerobic packaging and may mitigate age-related differences in color stability. Full article

Abstract
This study investigated the influence of CO2 levels (20–40%: M20, M30, and M40) in high-oxygen modified atmosphere packaging (Hi-O2 MAP) on microbial communities and quality attributes of chilled goat meat stored at 4 °C for 12 days. Alpha diversity indices (Chao1, [...] Read more.
This study investigated the influence of CO2 levels (20–40%: M20, M30, and M40) in high-oxygen modified atmosphere packaging (Hi-O2 MAP) on microbial communities and quality attributes of chilled goat meat stored at 4 °C for 12 days. Alpha diversity indices (Chao1, ACE, Simpson, and Shannon) revealed a significant decline in microbial diversity over time, with storage duration exerting a greater impact than packaging conditions. Nonetheless, MAP played a crucial role in shaping microbial profiles, with air packaging (AP) showing the most distinct community, while M40 differed notably from M20 and M30, particularly by day 12, as shown by beta diversity analysis using principal coordinates analysis (PCoA). Proteobacteria and Firmicutes dominated microbial composition, with Pseudomonas and Brochothrix linked to spoilage in AP, while MAP, especially M40, favored the growth of Lactococcus, Acinetobacter, and Vagococcus, enhancing microbial stability. Despite pathogen levels remaining within safe limits, AP exceeded the spoilage threshold (TVC > 7.00 log colony-forming unit (CFU)/g), whereas all MAPs extended shelf life, with M40 most effectively suppressing microbial growth (p < 0.05). Interestingly, metagenomic functional profiling revealed that elevated CO2 levels (>30%) altered metabolic pathways, shifting spoilage mechanisms from protein degradation in AP to carbohydrate metabolism in MAP, potentially influencing odor and texture attributes. MAP, particularly M40, also reduced protein and lipid degradation and oxidation, as indicated by lower total volatile base nitrogen (TVB-N), thiobarbituric acid reactive substances (TBARSs), and shear force, suggesting better prevention of increased meat hardness and the development of undesirable odors and flavors, although high CO2 negatively affected redness. Overall, M40 provided the greatest microbial stability and shelf life extension, highlighting the potential of optimized CO2 levels in Hi-O2 MAP to preserve goat meat quality and regulate spoilage dynamics.

This paper introduces a novel cold storage: phase-temperature storage, which is characterized by its distinctive coupling jacket structure that connects the sub-storehouse units to the main storehouse. This innovative design facilitates heat transfer while effectively inhibiting mass transfer. Experimental results indicate that polyethylene film, with a thermal conductivity of 0.42 W/m·K, is a more suitable material for constructing sub-storehouses. Enhancing the surface area of the sub-storehouse and increasing convective wind speed are identified as key factors for improving convective heat transfer within the sub-storehouse. Moreover, the optimized design ensures a more uniform temperature distribution inside the sub-storehouse. In contrast to conventional cold storage, the defrosting unit in phase-temperature storage consumes only 5.72 units of energy under equivalent conditions, compared to 154.02 units for conventional cold storage. This demonstrates that the energy expenditure during the defrosting process of phase temperature storage is less than 4% of that required by conventional cold storage, achieving an energy savings rate exceeding 96%. Under identical circumstances, conventional cold storage consumes a total of 36.359 units of electrical energy for defrosting, with 34.231 units being released as defrosting waste heat into the cold storage environment, resulting in a loss rate of approximately 94.13%. Based on apple preservation experiments, phase-temperature storage exhibited significantly superior performance compared to conventional cold storage in terms of apple respiratory peak, weight loss rate, hardness, and TSS content, with respective values of 17.05 CO2 mg·kg−1·h−1, 2.89%, 9.29 N, and 16.3%. In contrast, the conventional cold storage group recorded values of 18.15 CO2 mg·kg−1·h−1, 5.16%, 8.42 N, and 14.9%. These results highlight the exceptional freshness-retention capabilities of phase-temperature storage, underscoring its considerable potential for application in storage systems. Full article

Enzymatic browning poses a formidable obstacle to the commercial sustainability of fresh-cut potatoes. Although the synergistic effects of bio-inductive technologies with natural compounds in anti-browning strategies have been observed, their full potential remains underexplored. To fulfill the demand for synergistic approaches in real-world applications, this research elucidates the complementary effects of short-term high-oxygen (HO, 80%) treatment of whole tubers in conjunction with cod peptides (CP, 0.1%) applied to fresh-cut potato slices in mitigating browning. The results demonstrated that the combined treatment (HO + CP) showed superior anti-browning efficacy compared to single treatments (HO or CP) and the untreated group (control). Specifically, peroxidase (POD) and polyphenol oxidase (PPO) activities were suppressed by 55.7% and 35.1%, respectively, under the synergistic treatment compared with the control after 8 days of storage. Meanwhile, increases in the activities of catalase (CAT), superoxide dismutase (SOD), and phenylalanine ammonia-lyase (PAL), along with an approximately 117% increase in total phenolic content, were noted with synergistic treatment. Furthermore, the combined treatment reduced malondialdehyde (MDA) accumulation by 17.5% on day 8. This effect may be attributed to enhanced antioxidant capacity and the preservation of membrane integrity. In summary, this novel strategy provides a practical synergistic solution for the control of enzymatic browning in fresh-cut potatoes. Full article
