Most
bottled fruit products are self-stable, with little chances of spoilage if
properly formulated and processed. This makes small processors averse to set up
quality assurance system as they feel it is not necessary for them. They also
feel it is something beyond them as they have seen laboratory only on cinema
screen. They claim that they are making products successfully, since long
without laboratory so why they need it now?
In
preparing these notes help from several books, and other published matter is
liberally taken. Besides it includes my practical factory experience of 35
years in food processing units. Here the quality assurance system actually
followed by fruit preservers in India is written. Most of the test to detect
adulteration has been copied from DART booklet of FSSAI.
A
quality assurance laboratory will ensure:
1.
Compliance
with FSSAI so right side of law.
2.
Uniform
quality
3.
Checking
of incoming raw and packing Material prevents loss due to improper quality of
material going into product
4.
Less
financial loss due to fermentation or other quality defect.
5.
Less
customer complaint.
The
quality control starts with inspection of inputs going to product. The product
under process and finished products ready for dispatch should also be tested.
These notes cover
Part one – Physical and instrumental analysis.
Part two – Chemical analysis by titration
Part three – Inspection of raw and packing material.
Part four – On Line Checking
Part five – Pickle
Part six – Murabba and candy
Part seven – Jam Jelly Marmalade
Part eight Beverages
Part nine Sauce
Part ten Vinegar
And
in the end useful chart, starting cost of laboratory and reference for further
studies.
Only
simple test, which does not require costly equipment have been included.
Standard food analysis book covers many tests, and for a busy entrepreneur it
is difficult to find the test of his interest. In these notes only test that is
done daily in Indian fruit processing unit has been included.
