The seasonality to which dry-cured products from Iberian breed pigs finished in Montanera (free-range rearing system with feed based exclusively on ad libitum consumption of natural resources; acorns and grass) are subjected could be overcome by pre-cure freezing. Three sets of Montanera Iberian presas (Serratus ventralis muscle) (n = 15) were established to assess the impact of frozen storage -0, or non-frozen, 3 and 6 months—previous to the technological process of curing—on the quality

Lower productive performance due to higher weight loss during curing, and lower colour intensity were observed in pre-frozen dry-cured lomitos. The fatty acid profile was more saturated, and the oxidative status increased as a result of pre-cure freezing. On the matter of texture, all parameters were modified, highlighting the higher values of hardness and shear force of pre-frozen dry-cured lomitos. The time that raw material was frozen exerted a slight, thus helping manufacturers to better address the gap between industry and consumer demand with minimal effect on quality traits.
