Emulsion type pork sausage was manufactured with
irradiated pork hams, pork back fat and additives (Table
1). Raw ground pork ham was homogenized and ground
for 1 min in a silent cutter (Nr-963009, Scharfen, Germany).
1.5% salt was added to the meat and mixed for 1
min, back fat was added after 3 min and the batters were
homogenized for 6 min. A temperature probe (Kane-May,
KM330, Germany) was used to monitor the temperature
of the emulsion, which was maintained below 10oC during
batter preparation. Batters were stuffed into collagen
casings (approximate 16 mm diameter; #180, NIPPI Inc.,
Japan) using a stuffer (Stuffer IS-8, Sirman, Italy), and
samples were heating at 80oC until 75oC at core temperature
for 30 min in smoke house and then cooled with cold
water for 10 min until 10oC at core temperature. The produced
samples were vacuum sealed in polyethylene bags
and stored at 4oC during analysis.
