Skinless precooked, uncured sausage links with and without potassium sorbate (0.1% wt/wt) were inoculated with salmonellae, Staphylococcus aureus, Clostridium perfringens, and Clostridium botulinum and held at 27 C to represent temperature abuse of the product. Total counts of uninoculated product showed that the normal spoilage flora was delayed 1 day when sorbate was present. Growth of salmonellae was markedly retarded by sorbate. Growth of S. aureus was delayed 1 day in the presence of sorbate, after which growth occurred to the same level as in product without sorbate. C. perfringens declined to below detectable levels within the first day in product with and without sorbate. Sorbate retarded the growth of C. botulinum. Botulinal toxin was detected in 4 days in product without sorbate but not until after 10 days in product with sorbate.

Advanced glycation end products (AGEs) are obtained intermediate from nonenzymatic reactions between reducing sugars and proteins, lipids, or nucleic acids and it's associated with diabetic complications. Today, potassium sorbate (PS), sodium citrate (CIT) and sodium benzoate (SB) were widespread used as food preservatives that can easily enter biological matrices. Here, the interaction between glycosylation Bovine Serum Albumin (BSA) and food preservatives individually and combination of two and three was studied by biochemical and simulation analysis.

Ethanolic cashew leaf extract (ECLE) is rich in phenolic compounds with diverse bioactivities and can serve as a safe natural preservative. This study evaluated the antifungal activity and application of ECLE for shelf-life extension of dried salted tilapia fillets. Several extraction methods, antifungal activity, and application of ECLE in dried salted tilapia fillets were investigated.

Article Synopsis
- Heat stress and low mango yields are major issues for growers, but licorice-root extract (LRE) and potassium sorbate (PS) have been shown to improve growth and fruit quality in mango trees.
- In a study, 'Osteen' mango trees were treated with various concentrations of LRE and PS through foliar sprays, resulting in increased leaf area, number of fruits, and overall yield, while also reducing sunburn damage.
- The treatments not only enhanced fruit quality by increasing sweetness and vitamin C content but also significantly improved antioxidant levels and total chlorophyll, making the combination of 6 g/L LRE and 3 mM PS the most effective for boosting mango productivity.
