A control product (2.6% NaCl) and different treatments with reduced levels of salt (1, 2.3% NaCl; 2, 2.0% NaCl; 3, 1.7% NaCl; 4, 1.4% NaCl) and increased amounts of calcium ascorbate with an equivalent ionic strength to that of the control were assayed. The percentages of reduction of sodium content in relation to the control were 15, 24, 37 and 45% and the supply of calcium was 26, 33, 42 and 50% of the Recommended Dietary Allowance (RDAs established by NRC, US) for treatments 1, 2, 3 and 4, respectively. Partial substitution of NaCl by calcium ascorbate caused higher acidification related with the higher lactic acid bacteria development and probably with the presence of calcium. The instrumental measurement of colour gave rise to some significant differences especially with the highest amount of calcium ascorbate (treatment 4), giving rise to significant higher a* and b* values and lower L* values in relation to the control. Treatments 2, 3 and 4 lead to products with lower hardness and gumminess values than the control. No problems related to the hygienic quality were observed. (C) 2000 Elsevier Science Ltd.
