Abstract

The global expansion of ultra-processed meat products (e.g., sausages, nuggets) faces dual challenges: microbiological safety risks from conventional thermal processing and rising consumer demand for clean-label, nutritious options. High-Pressure Processing (HPP) emerges as a promising non-thermal technology to address these concerns by inactivating pathogens while preserving sensory and nutritional quality. However, its industrial adoption is hindered by significant energy efficiency and scalability constraints. This systematic literature review synthesizes recent research to critically analyze these barriers. Methodologically, we conducted a Systematic Literature Review (SLR) using databases such as Scopus, ScienceDirect, Web of Science, and PubMed, focusing on studies related to High-Pressure Processing (HPP) applications in ultra-processed meats. Our analysis reveals that HPP consumes 2.5–3.2 kWh/kg up to 26× more energy than thermal pasteurization primarily due to hydraulic system demands and adiabatic heat dissipation during batch cycling. Scalability limitations stem from batch-based processing (3–7 min/cycle), vessel size constraints (<500 L), and capital costs reaching $2.5 million per unit, resulting in only 18% adoption by large-scale manufacturers. Energy recovery inefficiencies and product matrix variations (e.g., lipid-protective effects in emulsified meats) further exacerbate these challenges. Emerging solutions include semi-continuous systems (35% throughput increase), pulsed HPP protocols (18% energy reduction), and solar-hybrid installations (40% emission cuts), though economic viability remains problematic. We conclude that while HPP offers unparalleled safety and quality benefits, its scalability and energy intensity require coordinated innovations in process engineering, renewable energy integration, and cooperative industry models to achieve sustainable implementation.

Abstract

The release of azo dyes such as Methyl Orange (MO) from the textile industry poses serious environmental problems due to their toxic, stable, and difficult-to-degrade properties. Conventional treatment methods such as adsorption, coagulation, and chemical oxidation have not been able to effectively degrade dyes, so a more efficient and environmentally friendly alternative approach is needed. Photocatalysis technology is a potential solution because it can mineralize organic compounds into harmless products. However, conventional photocatalysts such as TiO2 NPs have limited activity in visible light due to their large band gap and high electron-hole recombination rate. This study aims to improve the photocatalytic performance of TiO2 NPs through the integration of nitrogen-doped carbon quantum dots (NCQDs) synthesized from orange peel waste using a one-step hydrothermal carbonization method, then composited with TiO2 NPs through a low-temperature hydrothermal reaction. Characterization was performed using SEM and SEM-EDX to analyze the morphology and elemental composition. Photocatalytic activity was tested against MO degradation under UV irradiation using a UV-Vis spectrophotometer. The results showed that the NCQDs/TiO2 composite had a homogeneous morphology and strong chemical interaction between NCQDs and TiO2 NPs. Degradation efficiency reached 32.5% in 90 minutes, higher than pure TiO2 NPs by 2.5%, with an increase in the reaction rate constant from 2.81×10⁻⁴ to 4.37×10⁻³ min⁻¹ and a decrease in half-life from 41.1 h to 2.65 h. Thus, the NCQDs/TiO2 nanocomposite based on orange peel has potential as a sustainable photocatalyst for the treatment of MO.
