| Summary: | This study was carried out to determine: the effect of two numbers of
washing cycle (twice and thrice washings) and four types of washing solutions (tap
water, NaCl, NaHCO3, and sodium phosphate buffer) on composition, functional
properties, and microstructure of surimi-like material made from duck meat (DSLM);
the cryoprotective activity of four types of low sweetness cryoprotectants
(polydextrose, trehalose, lactitol, and palatinit), compared to commercial blend
cryoprotectant (sucrose-sorbitol) and control on DSLM during frozen storage and
exposed to freeze-thaw cycles; and the physicochemical, textural and sensory
properties burgers made from DSLM (added with polydextrose and sucrose-sorbitol
blend) and compared to burgers made from chicken and duck meat. Three times
washing on duck meat was sufficient to remove the undesirable components in
surimi-like material such as fats and sarcoplasmic proteins, to concentrate the
myofibrillar proteins, to form a compact and dense structure of cooked gel which
resulted in high values of functional and textural properties. Among the washing
solutions tested, washing with tap water achieved the highest gel strength, hardness,
cohesiveness, and chewiness significantly; moderate increases in water holding
capacity (WHC), pH, protein solubility, lightness, and whiteness; and left a small
amount of fat. |
