Physico-chemical evaluation of three varieties of tejocote (Crataegus mexicana)

Tejocote has been used traditionally in Mexico since Pre-Hispanic times and currently its cultivation it is considered of lesser economic importance, is distributed mainly in the States of Mexico, Puebla, Tlaxcala, Chiapas, Michoacán, Hidalgo and Morelos. The tejocote groups together more than 150 species around the world, these 93 types are in Mexico, further studies in this species are scarce. Therefore this research was the analysis of physical and chemical strains of tejocote at the Universidad Politécnica de Francisco I. Madero. The results show that the criolla variety possesses a 65.64% humidity, on the other hand the highest percentage of protein was obtained in Calpan gold variety (3.80%), for the ether extract the criolla variety has a 41.11% fiber, criolla variety was the one that obtained the highest percentage (16.71%), °Brix criolla variety presented the higher value, which present greater weight was the Chapeado variety. This results will be a contribution to the added value given to these.
