- Pineapple
wastes are produced in bulk quantities throughout the world,
with rising issues on environmental impact
- Pineapple waste
showed higher concentration of crude fibre, non-reducing sugar,
protein, ascorbic acid and moisture content. Therefore pineapple
waste is used as substrate for growth of microbes in
fermentation process. Green mature pineapples are usually
allowed to ripen during storage.
- 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(30.5mg/100g) and ash(1.8mg/100g)respectively.
Pineapple waste contains high concentration of
biodegradable organic material and suspended particles.
Pineapple waste showed higher concentration of crude
fibre, non-reducing sugar, protein, ascorbic acid and moisture
content. Therefore pineapple waste is used as
substrate for growth of microbes in fermentation process.
- 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
enzyme is used like papain from papaya for tenderizing meat and
chill proofing beer; is added to gelatin to increase its
solubility for drinking; has been used for stabilizing latex
paints and in the leather-tanning process. In modern therapy, it
is employed as a digestive and for its anti-inflammatory action
after surgery, and to reduce swellings in cases of physical
injuries; also in the treatment of various other complaints.
- Pineapple
crowns are sometimes fed to horses if not needed for planting.
Final pineapple waste from the processing factories may be
dehydrated as "bran" and fed to cattle, pigs and chickens.
"Bran'' is also made from the stumps after bromelain extraction.
Expendable plants from old fields can be processed as silage for
maintaining cattle when other feed is scarce. The silage is low
in protein and high in fiber and is best mixed with urea,
molasses and water to improve its nutritional value.
- Pineapple juice
is taken as a diuretic and to expedite labor, also as a gargle
in cases of sore throat and as an antidote for seasickness. The
flesh of very young (toxic) fruits is deliberately ingested to
achieve abortion (a little with honey on 3 successive mornings);
also to expel intestinal worms; and as a drastic treatment for
venereal diseases. Indians in Panama use the leaf juice as a
purgative, emmenagogue and vermifuge. In Africa the dried,
powdered root is a remedy for edema. The crushed rind is applied
on fractures and the rind decoction with rosemary is applied on
hemorrhoids.
- Pineapple
leaves yield a strong, white, silky fiber and finds many
applications
