Evidence has linked excessive salt consumption to the development of chronic degenerative diseases. Therefore, special attention has been given to the consumption of healthier products with reduced sodium contents. This study aimed to develop a Mozzarella cheese with a reduced sodium content using a mixture of salts through acceptance testing and temporal sensory evaluation. The following 3 formulations of Mozzarella cheese were prepared: formulation A (control), which was produced only with NaCl (0% sodium reduction), formulation B (30% sodium reduction), and formulation C (54% sodium reduction). Every formulation was produced using a mixture of salts consisting of NaCl, KCl, and monosodium glutamate at different concentrations. The products underwent sensory acceptance tests, and the time intensity and temporal dominance of sensations were evaluated. The proportions of salts used did not cause strange or bad tastes but did result in lower intensities of saltiness. Mozzarella with low sodium content (B and C) had a sensory acceptance similar to that of traditional Mozzarella (A). Therefore, the use of a mixture of salts consisting of NaCl, KCl, and monosodium glutamate is a viable alternative for the production of Mozzarella, with up to a 54% reduction in the sodium content while still maintaining acceptable sensory quality.

It is well known that sodium chloride overuse has a positive association with blood pressure and hypertension, and it has been related directly to the development of cardiovascular diseases. Thus, the aim of this study was to evaluate the effect of reducing the sodium chloride particle size on the salting power and time-intensity profile in shoestring potatoes. We found that the amounts of sodium chloride with reduced particle sizes required to yield an equivalent salting power to 1.6% unmilled (common) sodium chloride on shoestring potatoes were 0.97, 0.862, 0.795 and 0.785% for salt particles with mean diameters of about 97, 37, 30 and 26 μm, respectively. Based on these salting potencies, it is possible to reduce the sodium chloride used in shoestring potatoes by about 39, 46, 50 and 51% with the mentioned salt particles, respectively. The reduction in the size of salt particles also resulted in a more rapid perception of the maximum saltiness in shoestring potatoes.

Purpose The purpose of this paper is to evaluate a shiitake mushroom extract as a potential natural taste enhancer in low-sodium beef burgers by means of sensorial and physico-chemical assays because nowadays there is a trend in the market for the development of clean-label products. Design/methodology/approach Ten formulations of beef burgers were developed, varying in the percentage reduction in NaCl (0-75 per cent) and mushroom water extracts (obtained from a 5, 12.5, or 20 per cent mushroom homogenate). Sensory characterisation was performed by time-intensity (TI) and acceptance tests. In addition, physico-chemical analyses (pH, yield, shrinkage, shear force, and colour) were conducted. Findings Extracts obtained from 5, 12.5, or 20 per cent mushroom homogenate (E1, E2, and E3, respectively) did not enhance the salty taste in formulations with a 0 or 75 per cent reduction in NaCl. In formulations with a 50 per cent reduction in NaCl, all the extracts enhanced salinity perception, with E3 being the most effective. E3 also increased acceptance of colour, aroma, texture, flavour, and overall perception, although it caused changes in some physico-chemical characteristics (pH, yield, shrinkage, shear force, and colour). Originality/value The shiitake mushroom extract is a natural ingredient with a potential to serve as a taste enhancer in meat and other food products, for the purpose of reducing sodium content without compromising sensory acceptability. Therefore, this extract will enable the development of healthier products (owing to a reduction in sodium) with preserved sensory quality and will meet consumers’ requirements for the minimal use of chemical additives in food.

Garlic and salt spice is widely used in Brazilian cookery, but it has a high sodium content; as high sodium intake has been strongly correlated to the incidence of chronic diseases. This study aimed to develop a garlic and salt spice with reduced sodium intake. Sensory evaluation was conducted by applying the spices to cooked rice. First, the optimal concentration of spice added during rice preparation was determined. Subsequently, seasonings (3:1) were prepared containing 0%, 50% and 25% less NaCl using a mixture of salts consisting of KCl and monosodium glutamate; a seasoning with a 0% NaCl reduction was established as a control. Three formulations of rice with different spices were assessed according to sensory testing acceptance, time-intensity and temporal domain of sensations. The proportions of salts used in the garlic and salt spice did not generate a strange or bad taste in the products; instead, the mixtures were less salty. However, the seasonings with lower sodium levels (F2 and F3) were better accepted in comparison to the traditional seasoning (F1). Therefore, a mixture of NaCl, KCl and monosodium glutamate is a viable alternative to develop a garlic and salt spice with reduced sodium intake.
