Many foods are produced with the use of the smoking process, whether natural or artificial. The smoke give flavor, and color characteristic to smoked products, the main compounds found in the smoke are formic, acetic, butyric, caprylic, vanillic and syringic, dimethoxyphenol, methyl glyoxal, furfural, methanol, ethanol, octanol, acetaldehyde, diacetyl, acetone and 3,4-benzo(a)pyrene. These compounds have since organoleptic properties, even bactericidal, contributing to the life of these products. The detection of carcinogenic compounds, such as 3,4-benzo(a)pyrene, has led to studies of the effect of the conditions of smoke generation in their production. The present comparative studies was performed with three turkey breast sausage, using differents methods of smoking, natural smoke, liquid smoke and natural. The sensory evaluation showed a significant difference p <0.05 for use with liquid smoke sausage, considering the external color attribute. This result was in agreement with the method of Hunter color, where this also significantly different. The results of the analyzes of water activity, acidity and microbiology were similar for the three smoked, there was no significant difference p> 0.05. The moisture from the outer surface was significant difference p <0.05 for all three smoked, being the highest value observed in sausage with liquid smoke. The carcinogenic compounds were observed in the three types of smoking, however, with values below the limits accepted by the European Communities of 5 mg / kg. Yield values were higher in sausages where it was used the liquid smoke. |
