Quality of instant noodles depending on frying process conditions


The objective of the research study was to determine the impact of the type of frying medium and of the frying parameters of instant noodles onto their quality. The scope of the research covered the assessment of the quality of frying medium and instant noodles produced. A mixture of palm olein and rapeseed oil, their proportion being 1:1, was used for frying. In the frying medium, the parameters of fat were measured: acid value, peroxide value, and content of polar compounds. Moreover, the composition of fatty acids (FA) was analyzed quantitatively and qualitatively using a gas chromatography method. In the end product produced, measured were the moisture, fat content, colour, and hydration time of the noodles. Based on the results obtained, it was found that both the type of frying medium and the heat treatment parameters impacted the quality of instant noodles. The frying temperature caused the moisture and fat content to differentiate. Its growth caused the fat content to increase and, at the same time, the moisture of the product to decrease. The increase in the length of frying time by 50 % did not impact the moisture, fat content, and colour brightness of the end products under analysis. Thus, the frying time had no statistically significant impact on the above named quality parameters of the end products under analysis (p = 0.05).
