Brief on Post Harvest Losses Effective Technologies for –
Harvesting Technologies Grading & Sorting Food Coating
Key Findings and Recommendations
India wastes 35% of the produce which constitutes a value of Rs. 500 crore
A majority of this percentage results from farm level wastages
Post farm gate wastages majorly occurs while transportation re-packaging & re-distribution losses
Post Harvest Losses…
Farm Level Wastages
Harvesting Technologies…
Reapers with efficient outputs –
Vertical conveyor reapers with cutting width of 0.9m and 1.2m
GRH-1.2 reaper operates with vertical upper delivery device
These reapers are widely adopted in south asian countries. The adoption level in India is at nascent stage
Harvesting Technologies …
Reapers with efficient outputs –
In dry fields with straight, suitable height stalks the reaper can reach high output of 2.5 –3.0 ha/day
It overcomes the shortcomings of existing reaper like field distractions, huge labour requirements and poor output quality
It utilises a diesel engine of 7-8 hp
These reapers are efficient enough to operate at a width of 1.5m
Harvesting Technologies …
Hoang’s combine harvester -
Utilses features like –
33 hp Second-hand 4-wheel drive with automobile chassis Vertically transferring-reaping part of vertical conveyor reaper width of 1.85m Transferring part to drum: conveyor belt with lug plates width 0.5m Threshing and cleaning part is vertically installed The combine works well in the well-timed dry fields.
Harvesting Technologies …
Self-propelled sugar cane harvester THM –
Sugar cane harvesting is costly and hard because of the manual steps- Cutting Whittling Top removing Tying Transferring
Conventionally the cost for cutting, whittling and top removing is 35 –40 man-days/ha constitutes of 60% of the total cost
Self-propelled sugar cane harvester can bring down the cost by 30%
Harvesting Technologies …
Maize combine harvester TBN –2
This way of harvesting is appropriate with new production process, protective and re-fertilize the fields
This harvester can overcome the current problems in design and manufacturing with marked effects of existing Maize harvesters
The machine picks corn, cuts the stalks then buries them in the ground
This harvester delivers an effective output of 0.2–0.25 ha/hour
Effective Sorting & Grading Technologies…
Belgian Electronic Sorting Technology is an innovative technology which uses laser machines to sort based on –
Colour Structure Size Shape differences &
Biological characteristics
Features which are invisible to the human eye but, are dangerous for human health, such as aflatoxins in nuts and carrots.
This technology is cost effective and is applicable to an extensive variety of food products:
Effective Sorting & Grading Technologies…
FLUO Technology -
Researched from the University of Brussels
Able to screen chlorophyll containing products like lettuce, spinach, peas and other green vegetables for foreign material contamination with minimal loss of good product.
It creates a kind of black and white contrast that results in a very high detection efficiency and very little false reject.
Effective Sorting & Grading Technologies…
Microwave Sensing grading Technology
The technology rectifies the fruit grading constraints on measurement systems immunity to metallic objects moving in the vicinity of the fruit operates at frequencies whose wavelength is smaller than the fruit.
Uses a focused beam system operating at frequencies above 8 GHz
Good results has been proved in kiwifruit, orange and avocado
This technology can be usefully applied for the measurement of fruit moisture content and dry matter
In the case of citrus fruits, their acidity, firmness and skin thickness can also be measured accurately
The avocado measurements have shown that moisture content, dry matter and stone size can all also be measured.
Effective Sorting & Grading Technologies…
NIR - Near Infra Red Sorting Technology
Sorts the produce not just by size and color, but by indicators of produce taste
This is done without damaging produce as no mechanical mechanism touches the individual fruit
Facilitate Brix sorting that …
Is effective at commercial packing speeds Provides superior accuracy Interfaces with most existing and new sorting machines Places control in the user's hands Provides solutions for all varieties of fruits Does not damage produce
Food Coatings…
Use of Morpholine in Apple Coatings –
Morpholine is a substance which is added to some waxes used to coat apples
It is normally added to the wax as morpholine dissolves and spreads the wax
The wax is dried by a hot air treatment
Any residual morpholine evaporates
This is not practiced in India, even though the scope of apple exports, and
processing is increasing
Safety issues associated with this practice needs yet more research
Food Coatings…
Method of coating food products with un-gelatinized and unmodified high amylose starch prior to deep fat frying
This is the process for manufacturing ready to heat deep fried foods i.e french fries
The french fries are coated with 0.1 to 1.5 percent of an unmodified ungelatinized high amylose starch having an amylose content of at least 50 percent
The resulting product has improved texture and absorbs less oil than those french fries prepared by conventional methods.
This method has been incorporated by companies like McCain Foods
They have no adverse side effects to the human health
Food Coatings…
Protein coating technique developed by Proteus
Used mainly for frozen pre cooked/ fried food products
Can result in a 50 to 80 percent fat reduction in the final product
Research results show that up-to 90 percent reduction if fat can be achieved
Though adopted in the USA, the technology is yet to gain popularity in other parts of the world
The “Trans Fat” tag can up-lift the product overall quality
Corporate can create pull in the market for their products through this technology.
Key Challenges …
Lack of Technological Training Know-How
Customer AcceptanceFunding Assistance
Cost Effective Multi Commodity Integrated Technology
Governmental Interventions
Key Findings & Recommendations…
Intensive need of farmer as well as customer education
Technology up – gradation at the farm level
Capital infusion through private sector participation, FDI and FII’s
Risk management by providing services and information in time
Enabling regulations at farm level for uniformity in the produce
