UTILIZATION OF BY-PRODUCTS
AND TREATMENT OF WASTE
IN THE FOOD INDUSTRY
Mango kernel
• Made by: Mohamed Ramadan
INTRODUCTION
• A huge amount of waste is produced during mango processing which is a rich
source of many utilizable components
• By-products which can be used to feed livestock, These by-products are also
potential sources of pectin and phenolic compounds (antioxidants).
• Mango consist of between 33-85% edible pulp,
with 9-40% inedible kernel and 7-24% inedible peel.
MANGO BY-PRODUCTS
• Mango seeds (pits, stones): the seed represents from 20% to 60% of the whole
fruit weight.
• Mango seed kernels (mango kernels): the kernel inside the seed represents from
45% to 75% of the whole seed.
• Mango peels: the peels represent from 7% to 24% of the whole fruit weight Mango
waste: mango processing units yield mango wastes made of variable proportions of
peels, pulp, seeds and cull fruits.
BY PRODUCTS PROCESSING
• Juice from pomace
• Kernel flour
• Starch / fat from kernel
• Pectin from peel
• Biogas production from peel
MANGO KERNEL
• We can extract from kernel :
a) Mango kernel flour
b) Mango kernel oil / fat
• the nutrients analyzed from mango kernel flour
moisture, protein, fat, crude fiber , ash, calcium, magnesium, potassium, sodium,
manganese, copper, zinc and iron.
MANGO KERNELS FLOUR
Mango kernels
Cutting
Dried to 6-7% moisture
The outer skin is removed by rubbing and remaining portion is minced in mixture
Alcoholic extraction is carried out for 10-12 hr
Air drying or distillation of flour is done to remove alcohol
Milling in flour mill
USES OF MANGO KERNEL FLOUR
• Human food
• Animal feed and manure
• Starch manufacturing
• Oil and fat extraction
MANGO KERNEL OIL
Alcoholic extraction of fat from flour
Distillation to remove alcohol
Alkali refining of crude oil
Separation of oil
The mango kernel oil
contain high amount of
stearic acid used in( soap
manufacturing),also contain
oleic acid
