Hazard Analysis or “Hurdle Technology”? The past and present view of the safety of dry fermented sausages

Authors: Josef Kameník
Keywords: HACCP, air-conditioned drying chambers, curing, fermentation, starter cultures

The introduction of air-conditioned chambers has become an important factor in the area of quality control ensuring product standardisation and safety in the production of dry fermented sausages. The widespread use of starter cultures in the 1990s also made a contribution in this area. Critical control points alone cannot be relied on when the HACCP … [Read more…]

Co-extrusion technology for comminuted meat products: alginate as a “casing” of casingless meat products

Authors: Josef Kameník
Keywords: alginic acid, calcium ions, gel, production costs

The co-extrusion process is a good alternative to the standard production of small-diameter comminuted meat products whose batter is filled into casings. The principle of the co-extrusion process takes advantage of the ability of sodium alginate to develop strong and elastic gels on exposure to calcium ions. This method can be used in the preparation … [Read more…]

Boar taint

Authors: Josef Kameník and Jaroslav Kratochvíl
Keywords: androstenone, castration, sensory assessment, skatole

Boar taint is caused by a high concentrations of two compounds: androstenone and skatole. The threshold value of androstenone is between 0.5 – 1.0 µg.g-1  of fat, and that of skatole 0.2 – 0.25 µg.g-1  of fat. Both substances affect each other; they have a synergistic effect. In the adipose tissue of boars, the concentration of androstenone … [Read more…]
