• Dry spices are not normally subject to Spoilage but can get loaded with high mold spores
• However, the losses of flavoring constituents deteriorates the Flavor Profile
• Losses of the flavoring constituents can be minimized by
Processing of Spices By providing or modifying packaging conditions

Ability to protect the contents from spoilage and spillage
• Should offer protection against physio-chemical and microbiological spoilage w.r.t. storage condition
• Prevent the loss of volatile oils and also prevent the pick of foreign odor…i.e. off odor
• Prevent insect and fungal infestation and protect from other biological contamination and damage
• Assist in selling by suitable attractive outer graphics and should also conform to the food laws of the importing and exporting countries
• Should be economical and easily available

• Spice products are fumigated and are packed immediately
• Flexible packaging materials have varying degree of insect resistance
• Laminates based on foil or PET with PE is fairly insect proof.
• Metallised PET or PE and foil based laminates offer better resistance to insects compared to others.
• Inclusion of duplex board carton to unit packs

• The flavor is protected by outer natural coating and losses during storage are negligible
Gunny bags Polyethylene lined gunny bags
HDPE woven sacks PE lined plywood boxes Multi-wall paper bags Cotton bags lined with suitable polymeric materials

In case of whole dry chillies, due to the low bulk density, package becomes voluminous and suitable method has to developed to compress the chillies to reduce its bulk density.
Moisture content of 10% and pressure of 2.5 kg/ sq. cm was found optimum and it reduced the volume by 78% of its original value. Compressed packages of 10kg and 25kg are packed in PE bags.

Materials Used Desired Properties Disadvantages
Polyethylene (LDPE & HDPE), polypropylene
Retards ingress of water vapour
Printing gets disfigured and smudged
Offers inadequate protection against volatile oils
Cellophane or polyester Less permeability for organic volatile oils
Poor moisture barrier property
Laminates – cellophane/PE or PP, Glassine/PE or PP
Retain the volatile oil
Provide adequate
moisture
Under the conditions of high temperature and relative humidity these characteristics are lost
Metallised polyester/ PE or PP, Paper/ foil/ poly laminate, PET/met PET/ PE or PP
Good barrier against he loss of volatile oil and ingress of moisture, provides a shelf life of about 1 year
Delamination at high temperature

• Tightly closed glass
• Pure aluminum
• Suitable tinplate containers or food grade high density polyethylene containers.
• Essential oils are packed in epoxy coated aluminum narrow mouthed
bottle • PET and Colored PET

• Nylon and polyester based films
• Special foil laminates in combination with cellophane, PE, PET, Multilayered co-extruded nylon based films
• Films based on ethylene vinyl alcohol and PVDC coated BOPP with their very good aroma barrier property are also used
