Synergism between sodium chloride, sucrose and tricalcium phosphate in the osmotic dehydration of oca (Oxalis tuberosa) with and without chitosan coating
We investigated the synergistic effect of three solutes (sodium chloride, sucrose, tricalcium phosphate) in different combinations of concentration, on the moisture, solid gain and calcium gain in oca (Oxalis tuberosa) with and without chitosan (CR and SR). In both cases applied the Simplex with Ext...
