Techniques to Detect and Quantify the Bacterial Metalloprotease AprX in Bovine Milk: A Review. [PDF]

Compr Rev Food Sci Food Saf
ABSTRACT The heat‐stable metalloprotease AprX, secreted by psychrotrophic Pseudomonas spp., is a major cause of quality deterioration in dairy products, particularly ultrahigh temperature (UHT) milk. This review synthesizes the evolution and current state of detection and quantification techniques for AprX in bovine milk, covering traditional ...

Natural Antimicrobial Activity of Nettle (<i>Urtica dioica</i> L.) Leaf Extract for Shelf-Life Extension of Mashed Potatoes. [PDF]

Food Sci Nutr
NLE exhibited strong antioxidant activity, with DPPH, ABTS, and FRAP values of 21.96 ± 0.76 and 17.51 ± 0.90 μmol Trolox/mL, and 5.93 ± 0.65 μmol Fe (II)/g, respectively. Cytotoxicity assessment using L929 fibroblast cells indicated that the extract was non‐toxic at concentrations relevant for antimicrobial application.
