Characteristics of Mango
Mango, known as the “tropical fruit king”, is the common fruit in most continents, especially in Asia, Africa and south America. In 2014, the annual output of mango is more than 45 million MT and ranks the 7th in global fruit production. Rich in Vitamin C, folate and dietary fiber, mango is not only as a nutrient source but also as an important source of livelihood for people in the tropics. However, with characteristics of short harvest time, limited storage life and transportation difficulty, fresh mango is normally processed industrially into chutney, pickles, curries, canned or frozen slices, puree, beverages and various dried mango products to extend its preservation time and enrich fruit market throughout the year.
Mango Products Processing Industry
Present problems and solutions
In mango processing industry, lots of factors will affect mango processing quality and hence affect the total profits. The following questions & answers would help you know more about mango industry:
1. Q: Can green mango which dropped from trees be preserved by pickling?
A: Green mango pickling is a traditional flavoring method. the seasonings for pickling are usually salt, sugar and hot spices. Pickled mango needs to be consumed quickly, or it should be preserved in refrigerator. Low temperature and dry air are the key to preserve pickled mango which can slow down mango’s rotten time to some extent.
2. Q: How to differentiate mango puree, pulp and concentrate?
A: Mango concentrate refers to the original juice which is water removed. After concentrating, the processed product is easier for long distance transportation. Mango puree contains pulp, juice, etc except the stone (seed) & skin, it is highly blended to a smooth consistency. Mango puree retains natural fiber and some phytonutrients which is more nutritional than juice. Mango pulp is defined as stringy solids which the juice has been squeezed out.
3. Q: Which variety is suitable for mango processing and further processing?
A: Mango variety and different maturing stages of mango will affect its processing product’s quality. Here is a list of top 10 stabilised varieties which ranks in descending order of commercial importance in the producing area: Tommy Atkins, Kent, Keitt, Palmer, Amélie, Valencia, Haden, Irwin, Osteen, Alphonso and so on. Please note: Each country’s suitable variety for cultivation is different, and the same variety may appear different characters in different cultivated countries. For example: the above top 5 mango varieties have been grown widespreadly in Latin America and Africa, while Osteen and Alphonso varieties are exclusively cultivated in Spain and India, respectively.
4. Q: What advanced technologies are applied in mango drying process?
A: Dried mango processing technology is one of the oldest method for preserving mango by reducing its water content. Industrial hot air drying method could not only prolong mango’s shelf life, but also add value to mango products, resulting in the increasing income of small scale farmers and processors. In factory production, dried mango processing steps include material selecting, washing, peeling and coring, cutting, blanching, drying and packing.
Here are operating points of dried mango slices:
√ Material selecting: Choose whole, plump mango fruit without mechanical damage, free of pests and fresh in appearance. It’s better to use the variety with high dry matter content, with small & flat core and less fiber, and material’s grade of maturity should be 80-90%. Then, trim both ends of mango and out them on the conveyor belt.
√ Washing: Trimmed mango on the belt would be conveyed to Fruit Vegetable Air Bubble Washing Machine. Air bubble washing machine is suitable for soaking, washing and removing dirt/pesticide residue of mango fruit under the multiple functions of integrating bubble, blast and spray cleaning methods.
√ Peeling and coring: Mango needs to be peeled because its skin contains tannin which causes mango browning and affects product quality. Mango peel and scar would be removed by Multifunctional Fruit Peeling Machine, and the machine could be equipped with stoning device which can complete fruit peeling, stoning and separating steps in one machine, high efficient and automatic. After stoning, mango cores with the remaining pulp can be further crushed by Mango Juice Machine to collect more juice.
√ Cutting: In order to get an uniform quality, it’s better to cut mango lengthways into 8~10mm-thick slices.
√ Blanching: Blanching helps sterilizing and color fixing mango slices. After blanching at 70—80℃ hot water for 15 seconds, the enzyme activity is inhibited and mango is kept in its original color. With Fruit Blanching Machine, the quality of product is improved by inhibiting enzyme, removing a strange taste and color fixing. After blanching, mango needs to be placed on the plate evenly for draining water and preparing for drying.
√ Drying: With the help of Hot Air Circulation Fruit Drying Machine, you just need to put the plate on the drying vehicle and pull vehicle into drying chamber and set temperature, the initial temperature could be controlled at 70 ~ 75℃ and the post-period temperature is 60～65℃. Hot air drying is a major way of processing agricultural and sideline products, its working principle is blowing the hot air into the chamber to heat the material and speed up the flow of air, so that the water is quickly taken away and mango slices will be dried. It is a low cost, versatile and simple method. Please note: you can flip over mango slices during drying, and the processing time is depended on the required moisture content after drying, usually about 15%~18%.
√ Packing: After drying, place dried mango slices in the sealed container for 2-3 days so that all parts of mango has a balanced water content and soft texture for convenient packaging, usually in sealed bags.
