Article Synopsis
  • Lactobacillus salivarius was successfully encapsulated using agave fructans and sodium alginate, creating microspheres that were tested for different properties and drying methods.* -
  • The study found that oven-dried microbeads performed best in simulated gastrointestinal conditions, while freeze-dried microbeads had better viability in cold storage.* -
  • All microbead samples retained significant viability after digestion, indicating their potential health benefits and suitability for incorporation into food products.*

Article Synopsis
  • * Investigated both corrective and preventive applications of LFUS, finding that the preventive mode significantly improved filtration efficiency by cutting operation time by 50% and increasing membrane permeability by 81%, without damaging the membrane.
  • * The SMF process maintained the physicochemical properties and the total soluble phenol (TSP) content of the juice, marking a novel approach to enhancing juice clarification while preserving bioactive compounds.

Foodborne pathogens are a grave concern for the for food, medical, environmental, and economic sectors. Their ease of transmission and resistance to treatments, such as antimicrobial agents, make them an important challenge. Food tainted with these pathogens is swiftly rejected, and if ingested, can result in severe illnesses and even fatalities.

The effect of chemical modification of fractions of native agave fructans (NAF), high performance (HPAF), and a high degree of polymerization (HDPAF) by lauroylation, acetylation, and succinylation reactions on their prebiotic activity, antibacterial properties were evaluated and survival of in a simulated gastrointestinal system. The characterization of the reactions was confirmed by NMR and FTIR. The lauroylated and succinylated fructan fractions showed higher antibacterial activity against pathogenic bacteria such as and than the unmodified ones.

The postharvest application of high degree of polymerization agave fructans (HDPAF) was tested, evaluating anthracnose disease, defense-related enzyme activities, and quality attributes in avocado fruit. Application of a 20% HDPAF solution showed a reduction in anthracnose severity (60%) and incidence (34%) compared to the other concentrations evaluated and the water-treated control. Polyphenoloxidase activity increased 4.
