Comprehensive Review on Advancements in Food Preservation Technologies for Quality and Sustainability

Food Chemistry International, EarlyView.
Preservatives limit microbial development, oxidation, and enzymatic degradation, resulting in better food quality and extended shelf life. Classified as natural, synthetic, or biological, each preservative has distinctive attributes and modes of action. Growing preference for natural preservatives aligns with clean label trends.

Stabilization Strategies for Catechins and Epicatechins: Recent Advances

Food Chemistry International, EarlyView.
Oxidation, epimerization, polymerization, and hydrolysis, driven by heat, pH, and oxygen, are pathways. Nano‐/microencapsulation maintains integrity with 70%–95% efficiency; biopolymer nanoparticles, starch/polysaccharide nanocarriers improve stability and dispersion. Lipid nanocarriers enhance bioavailability but raise oxidation risk.

Viability of microencapsulated and non-microencapsulated Lactobacilli in a commercial beverage

Biotechnology Reports, 2020
The survival rate of free and encapsulated L. acidophilus and L. rhamnosus into Doogh beverage and simulated gastrointestinal conditions during 42-day were studied. Microencapsulation considerably protected both L. acidophilus and L. rhamnosus in Doogh beverage storage and in gastrointestinal conditions. Microencapsulation provided better protection to
