Indian Standard SPECIFICATION FOR KUOA
( First Revision )
0. FOREWORD
0.1 This Indian Standard ( First Revision ) was adopted by the Indian Standards Institution on 18 June 1980, after the draft finalized by the Dairy Products Sectional Committee, had been approved by the Agricultural and Food Products Division Council.
0.2 WHOA (KHAVA, MATrA and PALGHOA) refers to the milk product prepared by partial dehydration of milk by heating under controlled conditions. Buffalo’s milk is usually preferred over cow’s milk for KHOA production, since the former gives greater yield and a more desirable body and texture.
0.3 KHOA forms an important base for preparation of indigenous milk sweets such as BURFI, PEDA, GULABJAMAJ\‘throughout India. KHOA making is one of the important methods adopted for conserving surplus milk. This standard is expected to help in the manufacture of good KHOA under hygienic conditions and in exercising necessary quality control.
0.4 During the process of KHOA production from milk, heat-coagulation of milk proteins, especially the whey proteins occurs and a characteristic cooked flavour appears. Further, the vigorous stirring of the hot mass exerts an appreciable homogenizing action, so that when the pat is formed, all the fat globules are entrained in the mass. The water is also dispersed as fine droplets in KHOA.
0.4.1 The colour of KHOA depends on the type of milk used, it is whitish from buffalo’s milk and yellowish from to cow’s milk, with a slight tinge of brown in each.
0.5 This standard was first published in 1968. Keeping in view the latest technological advances and product development, the Committee decided to revise this standard. The revision includes definitions and limits for different types of KHOA; revised limits for fat; and new requirements for titratable acidity; total solids; total ash; coliform and yeast and mould counts.

IS : 4883 - 1980
0.6 While formulating this standard, necessary consideration has been given to the relevant rules prescribed by the Government of India under the Prevention of Food Adulteration Act, 1954. This standard is subject to restrictions imposed under the Act and the Rules framed thereunder, wherever applicable.
0.7 For the purpose of deciding whether a particular requirement of this standard is complied with, the final value, observed or calculated, expressing the result of a test or analysis, shall be rounded off in accordance with IS : 2-1960*. The number of significant places retained in the rounded off value should be the same as that of the specified value in this standard.
1. SCOPE
1.1 This standard prescribes the requirements and the methods of sampling and test for KHOA.
2. TERMINOLOGY
2.1 KHOA - shall be heat-coagulated milk-product obtained by partial dehydration of milk of buffalo, COW, sheep and goat or their admixture. Milk solidst suitably processed may also be used. It shall not contain any ingredient foreign to milk except the addition of citric acidt in DANEDAR KHOA (see 3.1.2) added to develop the desirable characteristic.
3. TYPES
3.1 The KHOA as presently being marketed is designated as given in 3.1.1, 3.1.2, 3.1.3.
3.1.1 PIjNDI- It is characterized as a circular ball of a hemispherical pat with smooth and homogeneous body and texture. The product shall be free from burnt particles as well as from any browning defects. The product should possess characteristic cooked flavour and also should be free from objectionable odour and sour ( acidic ) taste.
3.1.2 DAJVEDAR- It is characterized by its granular texture and uneven body. The size of grains depends upon the amount of coagulant added and the quality of milk used. Citric acid7 when added should

IS : 4883 - 1980
not exceed 0.1 percent of the product. This type of KHOA is used as a base for the preparation of KALAKAJD, cakes and pastries where granulation is valued to a great extent.
3.1.3 DHAP ( K-Al-CCHA MAWA) - It is characterized by loose and sticky body and smooth texture. It contains less than 60 percent by mass of total solids and higher moisture content than PIJVDI and DANEDAR types. DHAP is preferred for the preparation of GULAB3AMA.N as it forms uniform balls with desired rheological qualities after frying and soaking in sugar syrup.
4. REQUIREMENTS
4.1 Only fresh, sweet, clean milk, free from colostrum, and in every way fit for human consumption shall be used. The milk shall be free from adulterants, preservatives and any matter foreign to milk. The fat percentage of the milk shall be such that the final product conforms to the requirements given in Table 1.
4.2 Appearance and Colour - KHOA shall be free from signs of free fat, water seepage, and mouldiness. The colour of KHOA shall be white to pale yellow, may be with a tinge of brown.
4.3 Odour and Flavour - The KHOA shall have its characteristic flavour. It shall be free from objectionable flavours and odours.
4.4 Texture and Consistency -The KHOA shall conform to its type and designation. It shall have uniform texture and consistency. The surface of KHOA should not appear ’ dry ’ and nor should it be sandy.
4.5 The product shall be manufactured and packed in equipment and premises maintained under hygienic conditions ( see IS : 2491 - 1972* ). It shall also be stored and distributed under hygienic conditions.
4.6 The material shall also comply with the requirements specified in Table 1.
5. PACKING AND MARKING
5.1 Packing - All the material used for wrapping or packaging the KHOA shall be of such a nature as to impart no off-flavour or odour, nor in any other way contaminate the product packed under normal conditions of manufacture, storage and use.
*Code for hygienic conditions for food processing units (Jirsf revision ).

A-2. PROCEDURE
A-2.1 Direct Method -Weigh accurately about 2 g of KHOA in a porcelain dish. Add 3 ml of hot water and render into a fine paste using a pestle and mortar. Dilute by further adding 17 ml hot water, washing off any adherents from the pestle.
A-2.1.1 Add 1 ml of phenolphthalein indicator solution and titrate against standard sodium hydroxide solution. Stir vigorously throughout. The persistence of a slight pinkish tinge for 30 seconds indicates the end point.
A-2.1.2 Calculation
Titratable acidity ( as lactic acid ), percent by mass = 9 x AN
M
where
A = Volume in ml of standard sodium hydroxide required for titration,
N = Normality of standard sodium hydroxide solution, and
M = Mass in g of the material taken for the test.
A-2.2 Indirect Method - Proceed as in A-2.1. Add 10 ml of standard sodium hydroxide solution to the diluted product and after adding 1 ml of phenolphthalein indicator solution, titrate against standard hydrochloric acid. Stir vigorously throughout. The end point is indicated when the pink colour disappears completely.
A-2.2.1 Calculation
Titratable acidity ( as lactic acid ),
percent by mass = ( 10 - P) x 0.9 M
where
F’ = normality of standard hydrochloric acid, and
M = mass in g of the material taken for the test.
