VARIATION IN TEXTURE OF FARMED ATLANTIC SALMON ( SALMO SALAR L). RELEVANCE OF MUSCLE FIBER CROSS‐SECTIONAL AREA
ABSTRACT Mechanical properties were studied between and within fillets of 80 conventionally farmed Atlantic salmon (3.5 kg) using a Warner–Bratzler blade (WB) and a 12.5‐mm flat‐ended cylinder. The relationship between the muscle fiber cross‐sectional area versus mechanical response variables was ex...
