The Xenemetrix Legacy of Innovation
Continues
Food
is a market that offers many opportunities for EDXRF. Many
seasonings can be measured by looking at the salt content,
to help control the taste. There are a number of minerals
and metals added for extra nutritional value that must
be monitored to comply with Food and Drug Administration
regulations. There are a number of established applications
already.
Chlorine in snack foods
Chlorine is monitored to control taste or assure compliance
with low salt labeling of products. Snack foods like potato
chips, processed meat and cheese that are often high and
salt have been successfully analyzed by EDXRF.
Iron in Flour, Rice and Other Grain
Grains and processed flour have long been fortified with
iron, and EDXRF instruments are used to monitor it.
Calcium in Orange Juice, Cheese, and
Other Foods
Calcium has long been added to orange juice, and is frequently
added to many foods as a supplementary source of calcium
for the prevention of osteoporosis.
Titanium and Cookies and Snack Cakes
Titanium dioxide is used to make cookies cakes and fillings
whiter and brighter. It is in pretty high concentration
and is easily measured by EDXRF.
Iron in Milk Powder
Iron is added to milk powder as a supplement, and is commonly
analyzed by EDXRF.
Na, Mg, P, Cl, K, Ca, Mn, Fe, and
Zn in Pet Foods and Animal Feed
The nutritional value of pet foods and animal feed can be
controlled by routinely monitoring the product with EDXRF.
Al, and P in Dough
Aluminum and phosphorus are two more elements in addition
to iron that are usually in dough and can be measured by
EDXRF.
Ash in Flour
The ash that remains when flour is burned is composed primarily
of Na, Mg, K, and Ca oxides. The ash percentage and composition
have an affect on taste and mouth feel of product made
from flour, so they are routinely analyzed. EDXRF is an
excellent method for performing this analysis. |
