Effects of quality grade, aging period, blade tenderization, and degree of doneness on tenderness of inside round steaks
We used 162 inside rounds to determine the
influence of different quality grades, postmortem
aging periods, blade tenderization passes, and
degree of doneness on thawing and cooking
losses and Warner-Bratzler Shear force (WBS,
tenderness). Select (SEL), Choice (CHO), and
Certified Angus Beefâ„¢ (CAB) inside rounds
were aged for 7, 14, or 21 days and not tenderized
(0X) or blade tenderized one (1X) or two
(2X) times. Steaks from each inside round
were assigned randomly to final endpoint cooking
temperatures of 150, 160, and 170°F.
Percentage of thawing loss was higher (P<.05)
for steaks aged 7 days than steaks aged 14 and
21 days. For CHO steaks only, cooking loss
was higher (P<.05) for the 2X group compared
to the 0X and 1X groups. Steaks aged 14 and
21 days had lower (P<.05) WBS than steaks
aged 7 days. Cooking loss and WBS were
higher (P<.05) with each increase in endpoint
cooking temperature. Postmortem aging (14 or
21 days) and lower endpoint cooking temperatures
were the most effective methods to improve
WBS of inside round steaks
Effects of postmortem aging period and blade tenderization on sensory traits of beef steaks
We used 54 strip loins, 54 top sirloin butts,
and 54 inside rounds, all USDA Choice grade,
to determine the influence of different postmortem
aging periods and blade tenderization
passes on sensory panel traits. Cuts were aged
for 7, 14, or 21 days and not tenderized (0X)
or blade tenderized one (1X) or two (2X)
times. All steaks were cooked to 160°F internally,
and samples were evaluated by a trained
sensory panel for flavor intensity, juiciness,
myofibrillar tenderness, connective tissue
amount, and overall tenderness. Both longer
aging periods and blade tenderization passes
improved tenderness of strip loin and top sirloin
butt steaks without affecting either flavor or
juiciness, but did not affect tenderness of top
round steaks. Therefore, meat purveyors
should use these technologies to improve tenderness
and consistency of strip loin and top
sirloin butt steaks
A survey on the use of blade tenderizers by beef fabrication plants
A questionnaire to determine the use of
blade tenderizers in beef fabrication facilities
was sent to 241 members of the North American
Meat Processors Association (NAMP).
Eighty-four percent of the 90 respondents used
blade tenderizers. These subprimals were at
least sometimes tenderized by the following
percentages of respondents: tenderloins, 7.9;
chuck cuts, 18; round cuts, 36; ribeyes, 38;
strip loins, 56; and top sirloin butts, 62. If a
processor blade-tenderized a particular cut,
they tenderized a majority of their production
for that cut, generally with multiple passes
through the tenderizer. For example, the 62%
of respondents who tenderized top sirloin butts
tenderized 87% of their production of that cut
with an average of 1.6 passes. Cuts were aged
by 70.7% of respondents that used blade tenderizers.
The average aging period was 20
days, and the range was 7 to 60 days. Our
respondents fabricated 75.1% of their beef
products for the hotel/restaurant industry,
13.3% for retail, and 6.0% for other markets
such as export or warehouse distributors.
Blade tenderization is used widely by NAMP
members, most often on ribeyes, strip loins, and
top sirloin butts, and often combined with aging
Effects of quality grade, aging period, blade tenderization, and degree of doneness on tenderness of top sirloin butt steaks
We used 162 top sirloin butts to determine
the influence of different quality grades, postmortem
aging periods, blade tenderization
passes, and degree of doneness on thawing and
cooking losses and Warner-Bratzler shear force
(WBS, tenderness). Select (SEL), Choice
(CHO), and Certified Angus Beefâ„¢ (CAB) top
sirloin butts (n=54 for each) were aged for 7,
14, or 21 days and not tenderized (OX) or
blade tenderized one (1X) or two (2X) times.
Steaks from each top sirloin butt were assigned
randomly to final endpoint cooking temperatures
of 150, 160, and 170°F. Each longer aging
period resulted in lower (P<.05, more tender)
WBS. In addition, steaks blade tenderized 2X
had lower (P<.05) WBS than steaks not tenderized
or blade tenderized 1X. Within each
quality grade, WBS increased (P<.05) as
endpoint cooking temperature increased. When
cooked to 160 or 170°F, CHO and CAB
steaks had lower (P<.05) WBS than SEL
steaks. Increased aging periods and blade
tenderization passes of top sirloin butt steaks
improved tenderness. When cooking to higher
endpoint temperatures, using higher quality
grades will minimize toughness caused by cooking
Effects of quality grade, aging period, blade tenderization, and degree of doneness on tenderness of strip loin
We used 162 strip loins to determine the
influence of different quality grades, aging periods,
blade tenderization passes, and degree of
doneness on thawing and cooking loss and
Warner-Bratzler shear force (WBS, tenderness).
Select (SEL), Choice (CHO), and
Certified Angus Beefâ„¢ (CAB) strip loins were
aged for 7, 14, or 21 days and not tenderized
(0X) or blade tenderized one (1X) or two (2X)
times. Steaks from each strip loin were assigned
randomly to final endpoint cooking
temperatures of 150, 160, and 170°F. For
steaks aged 7 days, all quality grade and blade
tenderization treatments had similar (P>.05)
WBS. For steaks aged 14 days, CHO steaks
had lower (P<.05) WBS than SEL steaks,
CAB tended (P=.07) to have lower WBS than
SEL, 2X steaks had lower (P<.05) WBS than
1X steaks, and 1X steaks had lower (P<.05)
WBS than 0X steaks. For steaks aged 21
days, CAB steaks had lower (P<.05) WBS
than CHO steaks, CHO steaks had lower
(P<.05) WBS than SEL steaks, and 2X steaks
had lower (P<.05) WBS than 1X steaks.
Among the 0X and 2X groups, CAB and CHO
steaks had lower (P<.05) WBS than SEL
steaks. For the 1X group, only CAB steaks
had lower (P<.05) WBS than SEL steaks.
Blade tenderization improved tenderness of strip
steaks but should be combined with high quality
grades, increased aging, and lower endpoint
cooking temperatures to achieve maximum
tenderness
