3.3. Overall acceptability
This attribute provides an idea of whether the consumers
liked the meat since, in addition to tenderness
and flavour quality, there are many sensory attributes
that influence acceptability (juiciness, amount of residue,
greasiness, etc.). The effects of breed, slaughter live
weight and ageing are shown in Table 6.
In light lambs (20–22 kg), meat from Spanish Merino
(Table 7) was the most preferred at all times of ageing, as
previously reported by the taste panel for longissimus
lumborum (Martı ´nez-Cerezo et al., 2005). There was no
specific breed preference with regards to the overall
acceptability of suckling and early fattening lambs, but
in most cases this depended on the muscle and ageing
time. Alfonso (2000) compared the acceptability of leg
meat from 12 different types of lambs by consumers at
home and observed that Churra suckling lambs were
the most appreciated, followed by Rasa Aragonesa light
lambs in Spain. The latter type was also the most preferred
in the European Mediterranean countries. However,
Mendenhall and Ercanbrack (1979) did not
observe differences in consumer acceptance due to breed.
Slaughter live weight (Table 6) had the main effect on
overall acceptability especially for GB (higher F-value).
In general (Table 7), suckling lambs had higher marks in
all breeds, muscles and times of ageing, as expected from
results from tenderness (the most tender) and flavour
quality (the best scores), and as observed by Alfonso
(2000). However, Mendenhall and Ercanbrack (1979)
did not find differences on consumer appraisal at home
(tenderness, flavour, juiciness and acceptability) in eight
groups of lambs weighing 41.5–69.5 kg (slaughter live
weight), possibly because the differences in slaughter
weight were less than in our study.
Ageing did not influence overall acceptability of ST,
but it had the second most important effect on SM
and GB acceptability where intermediate to long ageing
were the best accepted (probably related to the effect of
ageing on tenderness and on flavour quality).
According to tenderness and flavour quality, ST had
the best acceptability scores at short times of ageing (1–2
days), and GB at longer ageing (mainly at 16 days of
ageing).
