3. DEFINITIONS  
 
3.1 Canned mangoes  
 An alimentary product prepared from peeled, stemmed, fresh, sound, clean, and 
mature fruit, and conforming to the propert ies characterized for the fruit of [Mangifera 
indica L.]  packed with or without a suitable liquid packing medium, nutritive 
sweeteners, seasoning or flavouring ingredients suitable for the product, and processed 
by heat, in an appropriate manner, before o r after being sealed in a container, in order 
to preserve its essential composition and quality factors.  
3.2 Mango pulp: It produces from edible portion of sound ripe mangoes after mixing 
,grinding ,naturalization and then filtered.  
3.3 Defects  
3.3.1 Blemi shes 
 Surface discolouration and spots arising from physical, pathological, insect or other 
agents that definitely contrast with the overall colour, and which may penetrate into 
the flesh. Examples include bruises, scab and dark discolouration.  
3.3.2 Crush ed units   
 Means a unit which has been crushed to the extent that it has lost its normal shape (not 
due to ripeness) or has been severed into definite parts (partially disintegrated halves 
are not counted as broken). All portions that collectively equal t he size of a full size 
unit are considered one unit in applying the allowance herein.  
3.3.3 Harmless extraneous material  
 Means any vegetable substance (such as, but not limited to a leaf or portion thereof or 
a stem or portion thereof) that is harmless bu t which tends to detract from the 
appearance of the product.  
3.3.4 Trim  
 Considered a defect only in halved and sliced canned mangoes in liquid media packs. 
The trimming must be excessive and includes serious gouges (whether due to physical 
trimming or oth er means) on the surface of the units which definitely detract from the 
appearance of the product.
