A. Berk et al., INFLUENCE OF VARIOUS VITAMIN-E SUPPLY TO FATTENING PIGS ON QUALITY OFPORK AND BACON DEPENDING ON TIME OF STORING, Zeitschrift fur Ernahrungswissenschaft, 37(2), 1998, pp. 171-177
99 individually kept, fattening pigs(castrated males) were divided int
o 3 groups. 33 animals each were supplemented with 0, 0.5 or 1.0 g alp
ha-tocopheryl acetate per day last 21 days before slaughtering. Sample
s from blood, liver, bacon, and muscle were taken to determine vitamin
E content by HPLC depending on time of storing. TEARS values of muscl
e and bacon, induction-time of bacon (''Rancimat''), pH, drip loss, an
d color of muscle were determined as further criterions of quality. Th
e Vitamin E supply increased significantly the vitamin E content of al
l samples (e.g., serum: 1.5, 2.4, and 2.7 mg/kg; liver: 3.8, 5.6, and
7.0 mg/kg for 0, 0.5, or 1.0 g per animal per day, respectively). Vita
min E content of pork decreased depending on time of storing (3.9, 6.2
, and 7.8 mg/kg vers. 1.9, 4.1, and 5.0 mg/kg after 29 weeks of freeze
storing). Storing time had no significant influence on vitamin E cont
ent of bacon. Vitamin E supply (esp. 1.0 g daily) decreased TEARS valu
es, increased time of induction and improved meat color, but did not i
nfluence pH and drip loss of pore significantly.
