A nutritional or dietary supplement or food product is provided that may be eaten by children or adults. The food product is made from cow's milk that has been heat treated to selectively denature allergenic proteins contained therein.

A high-pressure pre-heating system is provided for use in a spray dryer system. The high-pressure pre-heating system may include a heat exchanger(s) configured for high-pressure and high velocity product flow, with the heat exchanger(s) preheating liquid product immediately before spray drying. This arrangement reduces heat exposure time of the liquid product that flows at high velocity through the high-pressure heat exchanger(s), which correspondingly reduces the likelihood of fouling surfaces of the heat exchanger(s) or overheating the liquid product.

A method of making a fortified dairy product includes concentrating an amount of fruit juice and an amount of camel milk to obtain an amount of concentrated camel milk and an amount of concentrated fruit juice. The concentrated camel milk and the concentrated fruit juice can be heated and blended to produce a mixture. The mixture can then be spray dried to produce the fortified dairy product. The fortified dairy product can be a homogenous powder having a pH level ranging from about pH 4.5 to about pH 7.0.
