Eh. Mansour et Ah. Khalil, Characteristics of low-fat beef burgers as influenced by various types of wheat fibres, J SCI FOOD, 79(4), 1999, pp. 493-498
Hydrated wheat fibres (bran and white and red beeswings) were added at thre
e levels (50, 100 and 150 g kg(-1)) to beefburger as replacement for fat an
d evaluated for chemical and physical properties, energy content and sensor
y traits. Uncooked and cooked beefburgers formulated with wheat fibres had
higher (P less than or equal to 0.05) moisture, protein and carbohydrate co
ntents and lower (P less than or equal to 0.05) fat contents than that of t
he control. However, ash content was increased (P > 0.05) by the addition o
f wheat fibres. The cholesterol content of uncooked and cooked beefburgers
decreased as level of wheat fibres increased or fat content decreased. The
addition of wheat fibres reduced the cholesterol content from 6 to 45% for
uncooked and cooked beefburgers. The energy content of uncooked and cooked
beefburgers was lower (P less than or equal to 0.05) than that of control b
y between and 6 and 41%. The cooking yield and reduction in diameter of bee
fburgers were significantly (P less than or equal to 0.45) improved by the
addition of wheat fibres. The addition of red and white beeswings showed an
improvement in the texture trait. Colour traits, tenderness, juiciness, co
nnective tissue amount, beef flavour intensity and overall palatability wer
e not affected by the addition of wheat fibres to beefburgers. Hydrated whe
at fibres can be used successfully as a fat substitute in ground meat produ
