Dr. R. T. Patil Director, Central Institute of Post Harvest Engineering and Technology, Ludhiana Post Harvest Management and Value Addition with Special Reference to ASEAN countries

Production & Post Harvest Scenario:

Production & Post Harvest Scenario Agriculture contributes about 17.5% of GDP, employees 57% workforce and sustains approx over 70% of the population India produces about 230 million tons of food grains and 53.1 and 91.6 million tons of fruits and vegetables and ranks second in world Low level of processing of fruits and vegetables at only 2% . Food processing is employment intensive, creates 1.8 jobs directly and 6.4 indirectly for every US$ 25000 investment

Reasons for Losses :

Reasons for Losses Handling of raw produce through many stages of middlemen. Processing is mostly controlled by urban rather than rural entrepreneurs which leads to losses in valuable by products. Non availability of adequate and efficient equipment and machinery to be used in catchment areas. Low level of entrepreneurial urge in rural areas due to constraints of finance, assured market and proper training on technology On the whole, there exists a fragmented and inefficient value chain Higher the Value Addition Better the PH Management and Lower Will Be Losses

Important Crops of ASEAN countries Member Nations Brunei Darussalam, Cambodia, Indonesia, Lao PDR, Malaysia, Myanmar, The Philippines, Singapore, Thailand, Vietnam Major crops Paddy, Maize, Soybean, and Sugarcane Major fruits and vegetables Cassava, Banana, Pineapple, Mango, Guava, Manggosteen.

Post Harvest Management & Value Addition of Mango:

Post Harvest Management & Value Addition of Mango India occupies 54% of the world's production Fruits are plucked from the tree when they are still hard and green. Correct maturity of mango fruit, Pressure tests are used as an indication of fruit maturity. Picking of fruits with stem slightly above the abscission point is recommended. Mechanical harvesting extends the shelf life Sorting the fruits in several grades is common in Gujarat and Maharashtra, particularly for 'Alphonso', in Chittoor district of Andhra Pradesh for 'Bangalora', and for 'Dashehari' in Uttar Pradesh. Sieves having circular holes of 8, 7.5 and 7 cm diameter are used to distinguish fruits by simple marks on the package. The most popular containers used for packing mangoes are baskets of various makes, whereas crates, boxes, etc. are used occasionally Value added products The mango pulp, mango juice, mango leather/bar, mango pickle, raw mango pulp RTS, mango slices in sugar syrup, raw mango toffees, mango shreds, mouth freshner, raw mango juice and powder etc are produced.

Post Harvest Management & Value Addition of Guava:

Post Harvest Management & Value Addition of Guava Shelf life under ambient conditions is 2 to 3 days on an average. Fruits are graded on the basis of their weight, size and colour. The shelf life can be extended upto 20 days by keeping them at low temperature of 5 0 C and 75-85% relative humidity. It can be stored for about 10 days at room temperature (18 0 -23 0 C) in polybags providing a ventilation of 0.25%. The shelf-life of fruits extention by waxing, shrink packaging and fungicide treatments. Packed in boxes or in baskets of different sizes Value added products from guava like guava pulp/paste, guava leather, guava bar, guava based RTS have been standardized. Similary osmo dehydrated guava rings and cubes have also been developed at CIPHET Ludhiana.

Post Harvest Management & Value Addition of Pineapple:

Post Harvest Management & Value Addition of Pineapple Fruits are graded based on size, shape, maturity, and free from diseases and blemishes. The cut surface is treated with a suitable fungicide to control fungal decay. For local markets, Packed in bamboo baskets lined with paddy-straw. The first layer of fruits is arranged in such a way that they stand on their stumps. For distant markets, fruit are wrapped individually with paddy straw and then packed. For export purpose the pineapples are packed into fibreboard or wood containers. When fruits are transported for long distances or to be stored for several days, refrigerated transport is required to slow down ripening process. Value added products - pineapple pulp, pineapple juice, pineapple jam, sliced pineapples in sugar syrup and osmo dehydrated pineapple candy can be produced from selected fully ripped pineapples.

Post Harvest Management & Value Addition of Bananas:

Post Harvest Management & Value Addition of Bananas The bananas are transported as bunch padded with banana leaves. A fungicidal treatment is applied to cut ends to prevent stem end rot. For exports, bananas are removed from the stem and hands and clusters of the bananas are packed in corrugated boxes with perforated polyethylene liners. The curved side of the hands is kept facing upwards making sure that the crown of the upper hands do not damage the banana underneath. Hands are graded based on the number and size of fingers in each hand. In the cold storage, bananas are stored at 13-14°C with 90-95% relative humidity. Value added products Banana Flower Pickle, Banana Chips, Banana Fruit Pickle, Banana Fig , Banana Ready to Serve Juice , Unripe Banana Powder

Post Harvest Management & Value Addition of Cassava:

Post Harvest Management & Value Addition of Cassava In India cassava is mainly grown in Kerela, Tamilnadu, Karnataka, Andhra Pradesh The CTCRI developed post harvest management and value addition technologies Tool for harvesting Method to prolong shelf life of fresh cassava Production of Cassava rava Production of Cassava Porridge Starch based biodegradable plastic Mobile Starch extraction unit Harvesting tool Chipping machine Chips dryer Mobile starch extraction unit

CIPHET Low Cost Grader:

CIPHET Low Cost Grader The spherical fruits roll down the pipes due to gravity and fall immediately wherever they find the space of their diameter. Grades 3: 25-40 mm, 40-55 mm, 55-70 mm and > 70 mm The collector is inclined at 10 ° so that the tomatoes slide directly in crates. The important feature of grader is its ability to adjust the gap between the pipes and inclination of grading table and hopper. It can also be used for other round fruits and vegetables.
