Abstract
Carrageenan, agarans and alginates are phycocolloids, which change the consistence of the foodstuff and prevent undesirable changes such as moisture migration or textural profile changes. These phycocolloids are additives used in large scale for all kind of food products. They are not absorbed for the human organism and do not introduce extra calories in the diet. The process of irradiation, is an alternative method of great potential, because do not increase the temperature and it is highly in the decontamination of food ingredients. In this work, agar alginates and carrageenan were irradiated as powder with different doses (0-10kGy) of Co-60 and the rheological functional performance of water solutions of the irradiated additives was studied. The results are analyzed taking in account the future applications of those additives in irradiated foods. The viscosity of these hydrocolloids shows a decrease when submitted to an irradiation with doses until 10 kGy. (author)
