2. INTRODUCTION
India is known as the “Home of Spices”.
Pepper is the king of spices and cardamom is the
queen of spices.
India contributes 75% of global spice production.
But the small quantity of 6-7% exported because
one of the reason is improper packaging.
In sub continent whole spices are bought mostly in
loose form, packaged spices are being sold in cities.
3. Nature and Deteriorative characteristics
o Loss of aroma and flavour
o Bleaching of colour
o Loss of free flowing nature
o Microbial spoilage
o Insect infestation
4. Forms of spices
• Whole spices (cardamom, black pepper, clove, turmeric, ginger,
cinnamon, cassia)
• Seed spices (celery, fennel, cumin, fenugreek)
• Powdered spices(turmeric, chilies, ginger)
• Spice mixes (curry powders and masalas)
• Paste (curry paste, ginger-garlic paste)
• Concentrates (tamarind concentrate)
• Oil and oleoresins
5. Packaging methods
Bulk packaging:
• Traditionally jute bags are used for storage of spices in ware
houses.
• Capacity 10kg to 70kg.
• Jute bags provided with a loose linear bag of polyethylene.
• Double gunny bags are also used especially for whole
pepper.
• The quality of jute fabric with respect to grammage and the
weave.
• A twill, B twill and DW gunny are used depending upon the
value of the spice, their weave clearances 1-2%, 3-5% and
4-6%.
6. In the traditional packages maximum
loss of volatile oils up to 23% over a
year.
But these have the problem of moisture
ingress and sifting.
In such cases polyethylene lined jute
bags or HDPE/PP woven sacks are
used.
The plastic based packaging materials
also used to overcome the
contamination problems associated
with jute.
For some spices wooden and metal
containers lined with moisture barrier
materials are being used.
7. • The latest trend is to use jumbo bags(Flexible
intermediate bulk containers)(FIBCs) for exports of
spices.
• These bags have capacity up to 1 tonne.
• The jumbo bags are sometimes made cloth but mainly
from plastic fabric which can be laminated or provided
with an inner plastic linear bag.
• The bags are provided with filling and discharge
spouts and slings for hanging during loading/unloading
operations.
• For designing of jumbo bags factors such as capacity,
product protection requirement, bulk density of the
product, filling and discharge facilities at the users end
to be considered.
8. Intermediate packages:
Some traders use institutional packs for the
requirement of institutions like railways, educational,
air lines, hostels etc., for they use.
Capacities ranging from 2kg to 10kg.
The varieties of packages used include laminated flexible
pouches and plastic woven sacks.
It will replace the traditional materials like tin plate
containers and jute bags.
Unit or Consumer packages:
• Whole spices are packed in 50 g to 1 kg units in polyolefin
pouches.
• Few brands are packed in PET/PE laminate for good
printability.
9. The package types generally used as consumer packs
are;
Glass bottles of various sizes and shapes with
labels and provided with metal or plastic caps.
The plastic caps have added inbuilt features of
tamper evidence, dispensing, grinding etc.
Printed tinplate container with/without dispensing
systems
Composite containers with dispensers.
Plastic containers with plugs and caps with
dispensing and tamper evidence features.
Printed flexible pouches – pillow pouch, gusseted
pouch, stand-up pouch.
Lined cartons
11. • The printable flexible pouches have recently become very popular.
• Depending upon the functional and marketing requirements, the laminate/film
can be made to serve a specific need
• The printable flexible pouches are generally laminates of various
compositions. some of the commonly used laminates are
Polyester/metalised polyester/LDPE
BOPP/LDPE
BOPP/metalised polyester/LDPE
Polyester/Al foil/LDPE
• Polyester(10 or 12 microns) and BOPP based laminates are generally more
popular for spice packaging.
