Distribution of ivermectin residues in different Zebu cattle tissues and its stability in thermally processed canned meat.

Ivermectin (IVM) is one of the most widely used antiparasitic drugs worldwide and has become the drug of choice for anthelmintic and tick treatment in beef cattle production. Drugs used in production animals requires a withdrawal period after treatment to avoid residual concentrations above the defined maximun residue level (MRL). The aims of this study were to quantify the residue level of IVM in different muscles of cattle at several different time periods following 1% or 3.

Application of thermally assisted high hydrostatic pressure to modify sorghum starch: multi-scale structure, techno-functional properties and digestibility.

Unlabelled: The effects of high hydrostatic pressure (HHP) (400-650 MPa) and holding temperature (25-50 °C) in thermally assisted HHP processing on multi-scale structure of starch (granule, crystalline and molecular), techno-functional properties, and digestibility of sorghum starch (SS) were evaluated. Response surface methodology has verified that the process impact on the modification of SS was dependent primarily on the pressure level. As HHP increased, processed SS progressively lost their granular structure and Maltese cross, indicating gradual structural disorder within the granules.
