Because of government, public health,
and professional organizations applying pressures on the food
manufacturers to reduce sodium intake, the food industry is
experimenting with salt alternatives and forms of salt to reduce
sodium intake. How will this fare in the long-term? Even now,
consumers are cautious about buying low sodium, no sodium, and
reduced sodium products because they claim this sacrifices flavor.
As a result, food companies are finding
less drastic ways to reduce sodium in foods without alerting
consumers. This involves stopping labeling claims on packages and
rebranding products to emphasize low sodium. The answer it appears
is to maximize how salt in the product interacts with the tongue.
Increasing the boldness of salt's flavor can be done by using
different crystal sizes and shapes as found in varieties of Kosher
salts, sea salts, and specialty salts. This is being tried by
increasing salt's surface area and reducing its general density for
products like chips, crackers, and some baked goods. Spanish
researchers have found a potential use of newly developed hollow salt
microspheres on commonly eaten foods could reduce sodium intake by
approximately nine percent.
“Several companies are also
developing products with potassium chloride in combination with salt
in order to reduce sodium in foods while masking the metallic taste
that can sometimes go along with potassium chloride. Applications
include salad dressing, mayonnaise, processed meat and poultry
products, cheese and dairy products, baked goods and snacks, as well
as prepared meals and entrees in restaurant chains. The next step
when reducing sodium and finding substitutes is to work on savory
notes to enhance salt’s flavor using glutamate-containing
ingredients such as glutamate-rich yeast and mushroom extracts.”
More on this below.
This is somewhat humorous, one company
is adding color to the salt with the use of fruits and vegetables to
show consumers how much salt they are adding to food. Innovation may
be taking its toll as some are using hot sauce, soy sauce, adding
smoke flavors to salts, and dairy product solids to foods. Reducing
sodium to a given product clearly will depend on the functionality of
salt in the product.
I think it will become wise, if not
mandatory, for all consumers to read the label and ingredient's
sections on food containers to avoid some of the problems the food
industry will be causing. I urge everyone to be cautious with foods
containing potassium chloride because of consuming an excess of
potassium. Please read my blog here on the potential interactions
and problems excess potassium may cause. Always talk with your
doctor before this becomes a problem. Potassium is essential for
life, but use caution to avoid excess.
In the italicized paragraph above, be careful of products containing
glutamate ingredients. Glutamate is a salt of glutamic acid or an
ester of glutamic acid. Not everyone can tolerate these, but the
number of these people is generally unknown because the medical
community generally does not test for these.
