Dairy processing industry is
concerned with the raising, producing, processing, and fabricating dairy
products which can either be used by the final consumers or by food processing
unit for further production. Moreover, the dairy processing industry occupies
an important place in the food sector which embraces the production of milk,
its preparation for sale and the manufacturing of other dairy products like
cheese, yogurt, etc. Dairy industry depends on milk processing which is a raw
material for any dairy product.
Objectives
of dairy development
Dairy development has two main
objectives that are to increase the total milk supply on commercial basis and
diversifying agricultural structure by developing dairy as a supplementary
which increases income. Dairy processing not only provides nutritional
importance, but also provides employment to thousands of people. Moreover, milk
processing is one of the few commodities which give the producer a large share
of what the consumer pays for it.
Apart from its nutritional
importance, milk processing gives a complete description of the processing,
production, and manufacturing stages of dairy products from the receipt of raw
materials to the packaging of the dairy products including the food quality
aspects. Besides, it also deals with the distribution, storage, and
transportation of dairy products.
Technology
in dairy processing
Nowadays, consumers demand highest
quality foods which are fresh, tasty, as well as nutritious. These demands have
created considerable interest in the development of the new dairy and food processing
techniques which is, the non-thermal techniques that include high hydro-static
pressure used to deactivate microorganisms. Besides, it offers the dairy
industry numerous applications to produce microbial safe milk with improved
characteristics.
High
pressure processing of milk and dairy products
Milk processing at high pressure
offers unique advantage for consumers as well as for the dairy industry which
can help destroy micro-organisms without causing significant changes to the
nutritional attributes of the processed foods. However, the high-pressure
treatment of food is usually carried out in the high range of about 300-1000 MPA
at room temperature or a little higher.
Further, there are some major
advantages of high pressure for milk processing that include:
- Elimination or avoiding thermal degradation of food components.
- High retention of flavor, color, and nutritional value.
- Energy efficient
- Reduction in the chemical additives
