3. fS QUALITATIVE
ANALYSIS OF
COCONUT

4. o of THE COCONUT (COCOSNUCIFERA L) IS AN

d 'ORTANT FRUIT TREE IN THE TROPICAL REGIONS
‘AND THE FRUIT CAN BE MADE INTO A VARIETY OF
@FQODs AND BEVERAGES. THE EDIBLE PART OF THE
COCONUT FRUIT (COCONUT MEAT AND COCONUT
WATER) |S THE ENDOSPERM TISSUE. ENDOSPERM
TISSUES UNDERGO ONE OF THREE MAIN MODES OF
DEVELOPMENT, WHICH ARE THE NUCLEAR.
CELLULAR AND HELOBIAL MODES AND THE
DEVELOPMENT OF COCONUT ENDOSPERM BELONGS
TO THE NUCLEAR MODE. INITIALLY, THE ENDOSPERM
1S A LIQUID CONTAINING FREE NUCLEL GENERATED
BY A PROCESS, IN WHICH THE PRIMARY ENDOSPERM
NUCLEUS UNDERGOES SEVERAL CYCLES OF
DIVISION WITHOUT CYTOKINESIS (THE PROCESS IN
WHICH THE CYTOPLASM OF A SINGLE EUKARYOTIC
CELL IS DIVIDED TO FORM TWO
DAUGHTER CELLS) CYTOKINESIS THEN OCCURS. @ MN
PROGRESSING FROM THE PERIPHERY TOWARDS THE
CENTRE. THUS FORMING THE CELLULAR ENDOSPE!
LAYER. AT RST. THE CELLULAR ENDOSPERM IS
TRANSLUCENT AND JELLY-LIKE. BUT IT LATER
HARDENS AT MATURITY TO BECOME WHITE ESH
(COCONUT MEAT). UNLIKE THE ENDOSPERMS OF
OTHER PLANTS (EG. WHEAT AND COM). THE
CELLULARIZATION PROCESS IN A COCONUT FRUIT
DOES NOT FILL UP THE ENTIRE EMBRYO SAC CAVITY.
BUT INSTEAD LEAVES THE CAVITY SOLUTION- LLED.
THIS SOLUTION 15 COMMONLY KNOWN AS COCONUT
WATER AND IT IS OF CYTOPLASMIC ORIGIN

MAKES AN EXCELLENT ORAL REHYDRATION SPORTS
OBEYERAGE - REPLACES ELECTROLYTES FROM EXERCISE.
STRESS AND ILLNESS

Pa à IN EXERCISE PERFORMANCE

+ NATURAL ISOTONIC BEVERAGE - CONTAINS THE SAME
LEVEL OF ELECTROLYTES FOUND IN HUMAN BLOOD

«HAS 16 TIMES THE AMOUNT OF POTASSIUM AS MOST
SPORTS AND ENERGY DRINKS (264 MG VS 125 MG /100
ML)

+REDUCES PROBLEMS FOR INFANTS SUFFERING FROM
INTESTINAL DISTURBANCES

+ CARDIOPROTECTIVE: HELPS REGULAR BLOOD PRESSURE)
(DUE TO HIGH POTASSIUM); IMPROVES CIRCULATION

+ AIDS IN KIDNEY FUNCTION INCLUDING THOSE WITH 6

KIDNEY STONES; NUTRITIONAL SUPPORT FOR THOSE WIT!
URINARY TRACT/BLADDER PROBLEMS

+ HELPS BALANCE BLOOD SUGAR IN DIABETICS.
