Abstract
Simple Summary
The native guajolote meat is an important dietary source of proteins of high biological value for the rural population of Mexico. However, many of its quality characteristics are still unknown. Therefore, the fatty acids (FAs) profile and nutritional indices of breast and leg meat of native guajolote subjected to two heat treatments (boiled and baked) were evaluated. The heat treatments increased the concentration of saturated (SFA) and monounsaturated FA (MUFA) in the meat; in contrast, the concentration of polyunsaturated FA (PUFA) decreased. Likewise, the dietary FA index and the atherogenic index increased in guajolote meat from the effect of the heat treatments, while the essential and hypercholesterolemic FA indices decreased. Based on the results obtained, heat treatments increase the content of SFA and MUFA in breast and leg meat of native guajolote. Baking is less favorable for both types of muscle.
Abstract
Meat is a complex food with a structured nutritional composition that makes it an essential component of the human diet. In particular, the meat of native guajolote that is traditionally raised in natural conditions is an important dietary source of proteins of high biological value for the rural population of Mexico. The study aimed to evaluate fatty acids (FAs) profile and nutritional indices of breast and leg meat of native guajolote subjected to two heat treatments. For the study, a total of sixty muscle samples (30 breast meat and 30 leg meat) from adult male native guajolotes were used. The FA profile and nutritional indices were evaluated in raw meat (control) and meat subjected to two heat treatments (boiled and baked). The heat treatments, independently of the type of muscle, increased (p ≤ 0.05) the concentration of saturated (SFA) and monounsaturated FA (MUFA); in contrast, polyunsaturated FA (PUFA) decreased. Likewise, the dietary FA index, which has a negative hypercholesterolemic effect, and the atherogenic index increased in guajolote meat from the effect of the heat treatments, while the essential and undesirable hypercholesterolemic FA indices decreased. In conclusion, heat treatments increase the content of SFA and MUFAs in breast and leg meat of native guajolote. Boiling or baking the meat deteriorates PUFAs but increases the nutritional indices. The present investigation would provide valuable information for the guajolote meat product processing.
