More precisely, the effects of different parameters are studied: (i) the nature of the oil and its composition (fatty acids and β-carotene content), and (ii) the process parameters (high or low frying temperature, number of frying baths, final water/oil content, etc.). This analysis will allow us to assess the variability of final products and the relevance of deep-fat fried foods as nutrient vectors, while also contributing to the study of suitability of SAIN–LIM scores for process assessment.
