2. Pineapple Wastes
Pineapple waste is known as a by
product of the pineapple processing
industry and typically consists of residual
pulp, peels and skin. However there are
many parts of pineapple that are unused
such as leaves, stem, outer skin and
others that we can reuse to produce new
products.
3. Pineapple wastes are
produced in bulk quantities
throughout the world, with
rising issues on
environmental impact
Crude fibre, non-reducing sugar,
protein, ascorbic acid and moisture
content.
4. Core, peel and leaves are considered as waste
portion in pineapple. Of the
pineapple processing wastes, 40 to 50 per cent
is constituted by peels, cores and
pomace and cannery waste constitute 60 per
cent & is reported that 40- 50 per cent of
pineapple is considered as discarded portion.
Pineapple is a rich source of ascorbic acid supplement to our
diet. Pineapple pulp waste showed maximum amount
of reducing sugars
5. Value added Products
Bromelain
Bromelain: The proteolytic
enzyme, bromelain, or
bromelin, was formerly
derived from pineapple juice;
now it is gained from the
mature plant stems salvaged
when fields are being cleared.
The yield from 368 lbs (167 kg)
of stern juice is 8 lbs (3.6 kg) of
bromelain.
The pineapple wastes juice
• The pineapple wastes juice contains
mainly sucrose, glucose, fructose and
other nutrients.
• The characterisation this waste is
needed to reduce it by recycling to get
raw material or for conversion into
useful product of highervalue added
products such as organic acid, methane
, ethanol, SCP and enzyme.
• Analysis of sugarindicates that liquid
waste contains mainly sucrose, glucose
and fructose. The dominant sugar
wasfructose, glucose and sucrose.
