Special Issue Information

Dear Colleagues,

In the presence of an exponentially growing economy characterized by fierce market competition, the need for feed, energy, and commodities can pose significant challenges regarding the sustainability and operational efficiency of the food and beverage industry. Growing concerns about the environmental impact and the need to optimize production processes have led to the adoption of green processing technologies. Incorporating such methods in the food and beverage sector can greatly decrease resource usage and waste production while ensuring the safety and quality of the food products and beverages. On the other hand, the use of rapid testing technologies offers the possibility of conducting fast and accurate analyses of raw materials, intermediate, and final products. This not only improves efficiency in quality control and food safety but also reduces response times to potential risks or incidents.

This Special Issue is dedicated to discussing advancements in sustainable, non-thermal food processing methods, for instance, ultrasound, high-pressure processing, cold plasma, pulsed electric fields, UV radiation, and microwave. A special focus is also placed on recent developments in chromatographic and spectroscopic techniques (LC-MS, GC-MS, NMR, FTIR, etc.) as well as rapid testing technologies (PCR, RT-PCR, and NGS). We invite the submission of original research and review articles covering any area described above.

Sincerely,

Dr. Konstantina Tsikrika

The high amount of starch in fruits is responsible for its post-processing cloudiness. In the current study, α-amylase from porcine pancreases was immobilized onto carboxymethyl cellulose/polyacrylamide (CMC/PAM) hydrogel. This in-house-built CMC/PAM-Amy hydrogel offers a more efficient and sustainable solution for apple juice clarification. To acquire the best immobilization efficiency, the concentration of glutaraldehyde crosslinker was optimized. Biocatalytic characterization studies were brought into consideration for free and immobilized α-amylase. The synthesized native and immobilized CMC/PAM-Amy hydrogels were also characterized using SEM, FTIR and XRD. Under ideal circumstances, the activity of CMC/PAM-Amy was up to 604 μmolmin−1, and its immobilization efficiency was 96.29 ± 1.15%. A kinetic parameters study resulted in a conspicuously lowered Km value for immobilized amylase, signifying its higher affinity for its substrate. CMC/PAM-Amy showed a half-life (t1/2) 3.5 times higher than free-Amy at 50, 55 and 60 °C. The higher values of the inactivation rate constant (kd), free energy of inactivation (ΔG*), enthalpy of inactivation (ΔH*) and change in entropy (ΔS*) of CMC/PAM-Amy manifested the enhanced thermal stability of amylase after immobilization. A reusability study revealed that immobilized amylase retained roughly 70% of its initial catalytic activity after six successive repetitions of the process. CMC/PAM-Amy displayed improved recycling ability operational stability and biocatalytic activity, rendering it an auspicious tool in decreasing the starch content of crude apple juice to about 61% of its total starch content before treatment. Moreover, the values of Brix, viscosity, acidity and turbidity were also decreased in CMC/PAM-Amyclarified apple juice. Therefore, immobilized amylases with other industrial enzymes could be an efficient tool for potential industrial application. Full article
