The objective of this paper is to treat microscopic comparative analysis of domestic pork ham and commercial pork ham, both to the longitudinal and the vertical view, by means of the optical microscope. The main purpose is to observe changes occurring in meat products after the technological process. Microscope objective gives a real, inverted, and enlarged the sample to be analyzed, and the eyepiece take this image and transforms it into a virtual, inverted, and enlarged so that the final image is virtual, upright and enlarged. After microscopic analysis shows that there are differences between traditionally produced ham and pork ham from supermarkets.
