Indian StandardSPECIFICATION FOR
MANGO KERNEL FAT
o. FORE WORD0.1 This Indian Standard was adopted by the Indian
Standards Institu-non on 16 July 1979, after the draft finalized by
the OIls and OilseedsSectional Committee had been approved by the
Chemical DivisionCouncil and the Agricultural and Food Products
Division Council.
0.2 Mango kernel fat is obtained from seed kernels of mango (
Mangl-fera indica Lmn.). Mango trees are abundantly distributed
throughoutIndia, There are many regional varieties of mango. The
fruit is botha delicacy and a food. The estimated production of
mangoes in Indiais around 7 rrnllion tonnes. Mango contains an
ovoidoblique solitaryseed, also called stone. The latter consists
of a hard shell and kernelinside. The potential availability of
mango kernels in the country ISaround one million tonnes which can
yield about 70 000 tonnes of mangokernel fat but its present
production IS not much.
0.2.1 The contents of stone in mango fruit. kernel in stone and
fat inkernel vary with the variety of fruit. On dry basis, stones
comprise 4 to14 percent of fruit, kernels 61 to 83 percent of
stone, and fat 7 to 11percent of kernels. The mango kernel meal can
be used as cattle feed,manure and for production of starch and it
has good export potential.
0.3 Mango kernels contain 7 to 1I percent greyish white coloured
fatwhich IS suitable for edible purpose after refining. The
characteristicsof mango kernel fat are such that It has good
potential as a cocoa-butter substitute. It may also be used for wap
making. Consideringthe good potential of availability and
suitability of this fat for varioususes including that for human
consumption, the concerned technicalcommittee decided to formulate
this standard.
0.3.1 The fatty acid composition and the analytical constants of
themango kernel fat also vary WIth the frurt variety. The major
fatty acidsare oleic (33 to 53 percent) and stearic ( 24 to 49
percent). The rawfat can be used in soap making and as a substitute
of tallow in textileindustry. Refined fat is suitable as an edible
fat, cocoa-butter extenderor substitute, in suppository bases and
III cosmetics formulations. Mangokernel fat has also good export
potential.

IS I 9231 - 1979
0.4 This standard contains clause 5.1 which calls for agreement
betweenthe purchaser and the supplier.
0.5 In preparation of this standard, substantial assistance has
beenderived from data supplied by the 011 Technological Research
Institute,Anantapur ( AP ), Hindustan Lever Ltd, Bombay and
Regional ResearchLaboratory ( CISR ), Hyderabad which is gratefuliy
acknowledged.
0.6 For the purpose of deciding whether a particular requirement
of thisstandard is complied with, the final value, observed or
calculated,expressing the result of a test, shall he rounded off
III accordance withIS : 2-I 960·. The number of significant places
retained in the roundedoff value should he the same as that of the
specified value in this standard.

2.1.2 Refi'led Mango Kernel Fat - Mango kernel fat obtained by
theprocess of solvent extraction which has been neutralized with
alkali,bleached with bleaching earth or activated carbon or both,

be doneby physical means
3. GRADES

3.1.2 The material of raw grade I is suitable for making
VANASPATIand refined fat and not for direct edible consumption.
3.1.3 The raw grade 2 of the material is intended for soap
makingand for other industrial uses other than VANASPATI and
refined oilmanufacture.
4. REQ.UIREMENTS
4.1 Description - The material shall be obtained from clean and
soundkernels of mango (MangifPTa indtca Lmn.) by the process of

matter, separated waterand added colounng or flavouring substances.
In addition, the refinedgrade of the material shall have acceptable
taste and odour and maycontain permitted anti-oxrdants ll1
specified quantincs as prescribed underthe Prevention of Food
Adultcrauon (PFA) Rules of Government ofIndia.
4.2.1 Solvent extracted fat shall be obtained from the seed
kernelsusmg solvent hexane conforming to IS : 3.J:70·1 '166·.
4.2.2 The clarity of the rnaterial shall be judged by the
absence ofturbidity after keepmg the filtered sample at 60°C for
24- hours.
4.3 Admixture with Other Oils or Fats - The material shall be
freefrom admixture with rnmeral or other oils or fats of vegetable
or animalorigin, when tested according to the methods prescribed
inIS : 548 ( Part II )-1976t.
4.4 The material shall also comply with the requirements given
