Caracterización de la goma obtenida de la semilla de Tamarindo (Tamarindus indica L.)

Abstract

The objective of the investigation is to characterize the gum obtained from the Tamarind seed (Tamarindus indica L.), being an alternative for the use of the pulp and seeds. The gum obtained from the Tamarindo seed was characterized by two treatments prior to obtaining the gum (GSS and GST). It was verified that the dried and roasted seed treatments intervene in the physicochemical, rheological, thermal and texture properties of the jam. The drying treatment was the most optimal, the yield was 20.92 percent, the pH 6.59, the density 0.98 grams per ml, the molecular weight 9.698 per 105 grams per mole and humidity 6.55 percent. . The rubber exhibited Newtonian behavior, specifically the thermal characterization that is highly thermostable. The gum is specified for the production of jam, being a substitute for pectin due to the similar characteristics in gel formation. Tamarind jam was made to verify the efficiency of the hydrocolloid in relation to pectin (control), the MGSS treatment complied with the parameters established by current legal regulations, pH 2.963, the acidity of 2.533 in relation to the percentage of acid tartaric, Brix degrees 65.90. The jam experienced a visco elastic behavior, as a function of the storage modulus (elastic) (G´), loss modulus (viscous) (G¨) and loss tangent (tan δ) as a function of the angular frequency. Sensory evaluation indicated that formulation made with pulp and GSS obtained acceptability by the panelists.
