Relationship between the properties of raw and cooked spaghetti - new indices for pasta quality evaluation

Abstrakt

The quality of pasta can be evaluated by mea-suring the characteristics which encompass the most important quality parameters, such as colour, cooking properties and texture. The aim of the study was to suggest new indices which can be used to evaluate the quality of pasta. For the tests, 15 samples of spaghetti (produced from either semolina or common wheat flour) were used. The bending test was performed for the determina-tion of the strength properties of raw pasta, while the pasta colour parameters were evaluated via the Commission Internationale de l’Eclairage system. The pasta cooking test included the evalua-tion of optimum cooking time, weight increase index and cooking loss. The samples of cooked spaghetti were cut, and the para-meters describing pasta texture were determined. Statistical ana-lysis showed significant correlations (α = 0.05) between colour parameters (lightness and redness) and pasta ash content (R = -0.90 and 0.84, respectively). The mechanical properties of raw pasta correlated positively with pasta density. The strongest cor-relation was found between pasta density and flexural strength. The destruction force for raw spaghetti during the bending test correlated significantly and positively with the cutting force of the cooked pasta. The obtained correlations can be helpful in pasta quality evaluation.
