Surface decontamination and quality enhancement in meat steaks using plant extracts as natural biopreservatives.

Nine plant extracts were evaluated as biopreservatives to decontaminate and maintain the quality of meat steaks. Most of the extracts exhibited a remarkable antibacterial activity against antibiotic resistant strains from Salmonella Typhimurium and Staphylococcus aureus. The pomegranate peel extract (PPE), cinnamon bark extract (CBE), and lemon grass leaves extract (LGE) were the most effective as bactericides, with minimal inhibitory concentrations (MIC) of 250, 350, and 550 μg/mL, respectively.

Infants exposure to aflatoxin M₁ as a novel foodborne zoonosis.

Occurrence of aflatoxin M(1) (AFM(1)) in infant formula milk powder (IFMP) and maternal breast milk (MBM) was investigated as a risk factor affects the health of newborns in Egypt. A total of 125 IFMP and 125 MBM samples were collected and examined for the presence of AFM(1) using competitive ELISA test. The results indicated that the relative risk (RR) of exposure to AFM(1) via consumption of MBM was higher than IFMP (RR; 1.

Antimicrobial textile treated with chitosan from Aspergillus niger mycelial waste.

The waste biomass of Aspergillus niger, following citric acid production, was used as a source for fungal chitosan extraction. The produced chitosan was characterized with deacetylation degree of 89.6%, a molecular weight of 25,000 dalton, 97% solubility in 1% acetic acid solution and comparable FT-IR spectra to standard shrimp chitosan.

Exploration of Islamic medicine plant extracts as powerful antifungals for the prevention of mycotoxigenic Aspergilli growth in organic silage.

Background: Feed contamination with mycotoxins is a major risk factor for animals and humans as several toxins can exist as residues in meat and milk products, giving rise to carry-over to consumers via ingestion of foods of animal origin. The starting point for prevention, in this chain, is to eliminate the growth of mycotoxigenic fungi in the animal forage. Ten plant extracts, recommended in Islamic medicine, were evaluated as antifungal agents against mycotoxigenic Aspergilli, i.
