ABSTRACT
There are multiple ways to preserve both dehydrated and vacuum foods using
various controlled conditions and different packages, weights and various
presentations with the purpose of providing shelf life and commercial life to foods
such as fruits, vegetables and meat.
In the present investigation, three formulations were made using different mixtures
of chaya flour and corn flour as follows: formulation No. 1 (937) 50% chaya flour and
25% corn flour, formula No. 2 ( 678) 37.5% chaya flour and 37.5% corn flour, formula
No. 3 (487) 25% chaya flour and 50% corn flour, where a test of sensory evaluation
using the subjective acceptance method to establish the formula with the highest
score on the hedonic scale, where it was found to be formula No. 3 487 with a score
of 6 points obtained from two sensory evaluation tests carried out on the three
formulations; It was also determined through an ANDEVA (Analysis of Variance)
statistical design that there was a statistically significant difference for the odor, flavor
and color attributes, less for the texture attribute than if there was a statistical
difference for the texture attribute in both sensory tests.
In the case of the bromatological evaluation of dietary fiber (F.A) of formula No. 3
(487), the following results were obtained: before cooking the tamale, 7.53% of F.A.
and after cooking 4.74% F.A. with a loss of 2.79% of F.A. which indicates that if the
chaya tamale made with a mixture of chaya flour and corn flour presents high
thermostability in crude or dietary fiber. |
