Maturity is the stage at which fruits and vegetables are fully developed and able to ripen normally after harvest. It is important to harvest at the correct stage of maturity to ensure proper ripening, long storage life, and high quality. Maturity can be determined using various indices, including visual characteristics like size, color, and firmness; physical measurements like specific gravity; and chemical analyses of total soluble solids and acidity. The stage of maturity at harvest influences quality attributes like flavor as well as storage life, so proper harvesting is essential.

Canopy management is the manipulation of tree canopies to optimize the production of quality fruits. The canopy management, particularly its components like tree training and pruning, affects the quantity of sunlight intercepted by trees, as tree shape determines the presentation of leaf area to incoming radiation.

At Taste Of Middle East, we believe that food is not just about satisfying hunger, it's about experiencing different cultures and traditions. Our restaurant concept is based on selecting famous dishes from Iran, Turkey, Afghanistan, and other Arabic countries to give our customers an authentic taste of the Middle East
3. MATURITY
It is the stage of fully development of tissue of fruit and
vegetables only after which it will ripen normally
During the process of maturation the fruit receives a
regular supply of food material from the plant
When mature, the abscission or corky layer which forms at
the stem end stops this inflow
Afterwards, the fruit depend on its own reserves
4. In addition to this, typical flavour and characteristic colour
also develop
It has been determined that the stage of maturity at the
time of picking influence the storage life and quality of fruit
when picked immature like mango develop white patches
or air pockets during ripening and lacking in normal brix
acid ratio or sugar acid ratio, taste and flavor
on the other hand if the fruits are harvested over mature or
full ripe they are easy susceptible to microbial and
physiological spoilage and their storage life is considerably
reduce
5. Such fruits persist numerous problems during handling,
storage and transportation
Therefore, it is necessary or essential to pick up the fruits
or vegetables at correct stage of maturity to facilitate
proper ripening, distant transportation and maximum
storage life
The postharvest quality of the product is fixed at the
harvest so proper harvesting is necessary
We can have good harvest if we harvest at proper time as
the development of the fruits is at later stage of
development
6. Fruits harvested too early may lack flavor and may not
ripen properly, deteriorate faster and have short shelf
life
while produce harvested too late may be fibrous or have
very limited market life
Yield may also be lower
Therefore harvesting of fruits and vegetables at proper
stage of maturity is of paramount importance for attaining
desirable quality
The maturity has been divided into two categories i.e.
7. Horticultural maturity/Commercial maturity
Stage of development when plant parts possess the
necessary characteristics preferred by consumers
Depends on the intended use e.g. papaya, jackfruit
Physiological maturity
Applies only to fruits and fruit vegetables
End of development stage
Ability to ripen normally after harvest
for distant market and storage,
o climateric fruits should be harvested at maturity before they
are ripe i.e. before climateric rise
o Non climateric fruits should be harvested at ripe stage
8. Importance of maturity indices
Maturity indices = harvest indices
Sensory and nutritional quality
Adequate shelf life
Facilitate marketing- standards

expanse of good eating quality
12. Maturity indices
Sign or indications of the readiness for harvest
Basis for determining harvest date
Two types of maturity indices
i) Subjective:
Qualitative
Use the senses (color, size, shape, sound, firmness, juice
content etc.)
ii) Objective:
Quantitative
Are measurable indices (TSS, TA, Starch content, oil content,
firmness, dry matter, Days after full bloom, heat degree day,
13. Types of indices
i) Visual indices
a) Size and shape:
Maturity of fruits can be assessed by their final shape and size at
the time of harvest.
Fruit shape may be used in some instances to decide maturity.
For example, the fullness of cheeks adjacent to pedicel may be
used as a guide to maturity of mango
Banana : angular shape changes to round
14. b) Colour:
The loss of green color of many fruits is a valuable guide to
maturity
15. ii) Physical indices
a) Firmness:
As fruit mature and ripen they soften by
dissolution of the middle lamella of the
cell walls.
In many fruits such as apple, pear,
peach, plum, guava, kinnow etc. firmness
can be used to determine harvest
maturity.
Penetrometer measures the pressure
necessary to force a plunger of specified
size into the pulp of the fruit.
Such pressure is measured in pounds
and kilograms force.
16. b) Specific gravity:
Specific gravity is the ratio of the density of a substance to the
density of a reference substance.
As fruit mature, their specific gravity increases.
This parameter is rarely used in practice to determine when to
harvest a crop
It is used to grade crops into different maturities.
To do this the fruit or vegetable is placed in a tank of water;
those that float will be less mature that those that sink.
In practice, the fruit or vegetable is weighed in air, then in pure
water. The weight in air divided by the weight in water gives
the specific gravity.
17. iii) Chemical Measurement
The total soluble solids of the fruit can be measured with
refractometer, which indicate the harvest maturity of fruits.
Acidity is readily determined on a sample of extracted juice by
titration with 0.1 N NaOH.
TSS/TA is better to judge maturity as it gives the sugar acid
blending of product
a) Total Soluble Solids
can be determined in a small sample of fruit juice using hand
refractometer
The refractometer measures the refractive index, which
indicates how much a light beam will be slowed down when it
passes through the fruit juice.
The refractometer has different scales (0-32OB), (28-62OB) and
(56-92OB) which can be read directly.
18. For large size fruits, these should be cut from stem to blossom
end and to the centre of the fruit to account for variability in TSS
from top to bottom and inside to outside of the fruit.
The fruit tissues should be macerated thoroughly in pastle motor
and then from the mescerated pulp the juice is extracted by
passing through muslin cloth.
A drop of juice is then put on the prism of the refractometer and
TSS content can be read directly on the scale.
However, in case of small fruits like grapes, the juice content
can be extracted by simply pressing the whole fruit.
19. b) Titratable acidity:
Titratable acidity (TA) can be determined by titrating a know
volume of juice with 0.1N NaOH to end point
The milliliters of NaOH needed are used to calculate the TA.
The TA expressed as percent malic, citric or tartaric acid can
be calculated as follows:
20. iv) Calculated indices:
a) Calendar Date/Days after full bloom :
Useful guide to harvest, where seasonal variation in climate is
small
This method works well when the blooming period is short
period
b) Heat Units:
It has been found that a characteristics number of heat unit or
degree-days is required to mature a crop under usually warm
conditions
It is based on the principle that growth of plant organ is
directly proportional with ambient temperature
21. V) Physiological Method:
Respiration rate:
Particularly on climateric fruits can accurately pin point the
most appropriate time of harvest as there is climateric rise
in respiration
Internal ethylene evolution:
Like respiration rise climateric fruits also have ethylene
peak
Volatiles production:
Apple: Ethyl-2-methyl butyrate
Banana: Eugenol
Grapefruit: Nootaketone
Lemon: Citral
22. Maturity indices should be
simple, easy to carry out
Objective vs subjective indicators
Related to quality
Related to storage life
Represents a progressive change with maturity
Premits prediction of maturity from year to year
inexpensive
23. Limitations of maturity indices uses
Soil conditions, nutrition, irrigation
Season , climate
Position on the plant
Pruning and other cultural practices and
management practices
