2.2. Processing of breakfast sausage
Fresh pork hams, weighing 6.8–7.2 kg each, were purchased
from a local processor at 48 h postmortem. Pork back fat was also
collected. All subcutaneous and intramuscular fat and visible connective
tissues were removed from the fresh ham muscles. Lean
meat and back fat were ground through an 8 mm plate. Breakfast
sausages were manufactured with following formulation; 50% lean
pork meat, 25% pork back fat, 25% ice, 1.5% sodium chloride, 0.15%
phosphate, 0.5% sugar, 0.05% onion powder, and 0.05% monosodium
L-glutamate. Control sample was produced without the addition
of powdered kimchi. Freeze dried kimchi powder (FKP) or hot
air dried kimchi powder (HKP) was incorporated into sausage at
levels of 1% (FKP-1 and HKP-1) or 2% (FKP-2 and HKP-2). The addition
of sodium chloride controlled as kimchi powder level because
kimchi powder had 10% salt content, therefore sodium chloride
added 1.5%, 1.4%, and 1.3%, respectively.
