    Abstract:
    Trial were conducted in Costa Rica in 1984 and 1985, to determine the possibility of substituting pejibaye (Bactris gasipaes H.B.K.) meal for wheat flour in bread. Utilization in three distinct mixtures was examined: 90:10, 85:15 and 80:20 percentage of wheat flour to percentage of pejibaye meal, respectively. The breads were made, and dough analyses were conducted at "Molinos de Costa Rica, S.A.", the country's principal flour mill. Chemical analyses were carried out at the University of Costa Rica. Results indicate a marked inverse relationship between both initial dough development time and dough strength maintenance, and the content of pejibaye meal present in the flour mixture. Consequent problems with sufficient dough expansion preclude utilization of this fruit meal for bread-making in proportions significantly greater than 10% of the total composite flour. The above-mentioned findings reflect the high nutritional value of the pejibaye fruit. Although the protein content is inversely correlated with the amount of pejibaye meal in the mixture, vitamin A and fat contents are positively correlated. This fact demonstrates that the utilization of pejibaye meal in bread-making may well be in some ways considered as a form of nutritional enrichment. As a final conclusion drawn from the results of analyses of the trials and sensory observations, the 90% wheat flour with 10% pejibaye meal mixture apparently was the optimum substitution level of the breads examined. The potential macroeconomic ramifications on the Costa Rican economy of producing and utilizing pejibaye meal in bread-making, are highly favorable.
