    Canning Practice

    • Canning Practice (1) Objectives and Tasks


    • Canning practice (2) Explanation of the process


    • Canning practice (3) Pre-treatment; cut of mackerel
      Cut into appropriate sizes for canning.

    • Canning Practice (4) Salted Mackerel and Boehme Density Meter
      Cut mackerel meats are soaked in brine at an appropriate concentration.
      The amount of salt dissolved in the soaking brine is determined using a specific gravity meter (Boehme Density Meter).

    • Canning Practice (5) Salting
      Before filling the cans, the fish meat is immersed in brine.
      The scientific reason for this is explained below.

    • Canning practice (6) Filling mackerel cans
      The meat is packed in empty cans in a specific way.

    • Canning Practice (7) Explanation of Vacuum-can-seaming mechanism


    • Canning practice (8) Sealing cans using the automatic vacuum seaming machine
