Study of Electrospun Membranes Composed of PCL and Tilapia-Skin Collagen with Tetracycline or Chloramphenicol in Contact with Human Skin Fibroblasts for Wound Dressing Treatment.

Diabetic foot ulcers are a common complication of diabetes mellitus and can lead to severe infections and delayed wound healing. The development of effective wound dressings is crucial to promoting faster healing and preventing infections. This investigation aims to fabricate and characterize electrospun meshes composed of poly(ε-caprolactone) and collagen, extracted from tilapia skin.

Influence of pH, ionic strength and isoascorbic acid on the gel-forming ability of Jumbo squid muscle (Dosidicus gigas).

The effect of pH and ionic strength (μ) on the extraction capacity of myofibrillar proteins from Jumbo squid mantle muscle along with the addition of isoascorbic acid (IA) in its gel-forming ability (GFA) were evaluated. The results indicate that μ had a greater impact (p < 0.05) than pH on the extraction of muscle myofibrillar proteins.

Biological and functional properties of peptide fractions obtained from collagen hydrolysate derived from mixed by-products of different fish species.

Fish by-products are excellent sources of collagen. Acid-soluble collagen (ASC) derived from a mixed by-product of different fish species was hydrolyzed to obtain peptide fractions and evaluate their biological and functional activities. All fractions obtained (F1: ≥30, F2: 10-30, F3: 5-10, F4: 1-5, and F5: ≤1kDa) exhibited antioxidant activity at concentrations of 5, 10, and 15 mg/mL.

Effect of ante-mortem hypoxia on the physicochemical and functional properties of white shrimp (Litopenaeus vannamei) muscle stored on ice.

The effect of ante-mortem hypoxia on the physicochemical and functional properties of raw and cooked white shrimp was studied. Hue angle was greater (p ≤ 0.05) for stressed raw shrimp compared to control (greener color); whereas a lower angle was detected for cooked stressed shrimp (redder/orange coloration).
