Abstract
The aim of this work was to determine the impact of pitahaya peel flour (PPF) addition, at different concentrations (1.5 and 3%) on the chemical, physico-chemical and sensorial properties of beef burgers. This assessment was based on: proximal analysis, physico-chemical and cooking properties, lipid oxidation and sensory assay of beef burgers. The burger reformulation with pitahaya peel flour had no effect (p > 0.05) on the chemical composition of raw burgers, whilst the cooked burger increased (p < 0.05) the protein and fat content and in the same way increased the calcium, potassium and phosphorus content (p < 0.05) with respect to the control sample. The colour coordinates redness (increased) and yellowness (decreased) were affected (p < 0.05) by the pitahaya peel flour addition. From a textural point of view, all parameters, except springiness, were affected (p < 0.05) by the incorporation of pitahaya peel flour. In addition, the use of pitahaya peel flour reduces (p < 0.05) the cooking loss and the shrinkage of burgers. The raw and cooked beef burger added with pitahaya peel flour showed lower lipid oxidation values (p < 0.05) than those of the control sample. The hedonic scores for all burgers analysed ranged from 6 to 7, which indicates a high degree of acceptance by the panellists. The results obtained indicated that pitahaya peel flour could be used as a novel ingredient in the development of beef burgers.
期刊介绍:
The journal European Food Research and Technology publishes state-of-the-art research papers and review articles on fundamental and applied food research. The journal''s mission is the fast publication of high quality papers on front-line research, newest techniques and on developing trends in the following sections:
-chemistry and biochemistry-
technology and molecular biotechnology-
nutritional chemistry and toxicology-
analytical and sensory methodologies-
food physics.
Out of the scope of the journal are:
- contributions which are not of international interest or do not have a substantial impact on food sciences,
- submissions which comprise merely data collections, based on the use of routine analytical or bacteriological methods,
- contributions reporting biological or functional effects without profound chemical and/or physical structure characterization of the compound(s) under research.
