Abstract

This work seeks to formulate low-fat frozen pre-fried potato croquettes with a healthy nutritional profile, comparing their characteristics with market products. The filling and batter were formulated seeking to reduce the absorption of oil, using xanthan gum in the filling (0.15 %, 0.25 %, 0.35 %) and in the batter (0.15 %, 0.50 %, 0.85 %). The croquettes were prepared by pre-frying at 180 °C for 50 seconds, then frozen. The cooking of the croquette was finished by frying at 180 °C for 3 minutes. The formulated croquettes were analyzed and compared to 2 commercial products, based on fat content, instrumental texture, and instrumental color. It was observed that the fat reduction was significant, with values lower than those of the market. The sample with the lowest percentage of fat (1.8 %) contained 0.35 % filling and 0.50 % xanthan gum coating. On the other hand, the highest percentage of fat absorption (9.4 %) was obtained from the sample with a xanthan concentration of 0.15 % in the batter and 0.25 % in the filling. The maximum percentage of fat reduction was 81 %. Concerning instrumental texture and color, no significant differences were observed among the experimental croquettes. However, they did differ from the commercial products. Finally, the croquette with the lowest fat content was subjected to sensory comparison against the commercial croquettes. The selected formulation (0.35 % xanthan gum in the core - 0.50 % xanthan gum in the coating) showed similar acceptability to one of the commercial products and significantly higher acceptability compared to the other, indicating a potential market for this product. So, it was possible to significantly reduce the absorption of oil from fried croquettes by only modifying its formulation and thus obtain a product with a lower fat content than its market counterparts and with a higher acceptability by consumer.
