Indian Standard
COD-E OF PRACTICE FOR COLD STORAGE OF SHELL EGGS
0. FOREWORD
0.1 This Indian Standard was adopted by the Indian Standards Institution on 30 May 1972, after the draft finalized ~by the Meat and Meat Products Sectional Committee had been approved by the Agricultural and Food Products Division Council.
0.2 With the recent development of the poultry industry, the production of eggs has registered ,a significant increase in the country. With a view to preserving the surplus production of eggs during the lean season of consumption for use during the peak season, proper storage assumes paramount importance. It is hoped that this standard would help in minimizing the loss of eggs due to deterioration in the quality during preservation.
0.3 In the formulation of this standard considerable help has been rendered by the Indian Veterinary Research Institute, Izatnagar.
0.4 In the formulation of this standard, due consideration has been given to the Agricultural Produce ( Grading and Marking ) Rules, regarding grading of shell eggs.
0.5 For the purpose of deciding whether a particular requirement of this standard is complied with, the final value, observed or calculated, express- ing the result of a test, 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 code covers the guidelines for cold storage of shell eggs.
2. TERMINOLOGY
2.0 For the purpose of this standard, following definitions shall apply.
*Rules for rounding off numerical values ( revised ).
3
IS : 6558 - 1972
2.1 Grading-Sorting of eggs ,according to quality, size, weight and other factors that determine their relative value,
2.2 Candling - Process of holding the egg before a beam of light in such a way that the light rays penetrate and illuminate the interior of the egg for inspection.
2.3 Yolk Faults
2.3.1 Sided - Yolk displaced to an appreciable extent from its normal central position.
2.3.2 Stuck - Yolk stuck to the inner shell membrane.
2.3.3 Patchy -Yolk uneven in colour including defects sometimes described as ‘ heated ’ or ‘ heat spots ‘.
2.3.4 Abnormal Shape -Yolk flattened or irregular, which in extreme cases, may be broken and dispersed in albumen.
2.3.5 Discolowed - Yolk of a dark or greyish appearance often with a very distinct outline.
2.3.6 Embryonic Development - Thin blood vessels and bright blood ring may be seen.
2.4 Specific Faults - Such as blood spots; blood egg; meat spots; staleness: mold growth; rot; taint; thin-shelled eggs; yolkless eggs; and double-yblked eggs. .

3.1 Eggs, prior to cold storage, shall be given in Table 1.
4. SORTING AND CLEANING OF
4.1 Prior to cold storage, clean shell eggs, shall be separated from the soiled ones.
4.2 Cracked and unsound eggs or those with yolk faults and/or specific faults shall be removed through the process of candling. not be stored.

5. ARRANGEMENT OF EGGS FOR COLD STORAGE
5.1 Eggs for storage shall be arranged with pointed end down and broad end up, in the filler flats. Each filler flat may contain about 30 eggs.

5.3 While arranging the eggs in the collapsible boxes care shall be taken to place an empty filler flat on the top before closing the top sides of the egg boxes.
6. METHOD OF COLD STORAGE
6.1 Eggs meant for cold storage shall be treated before storage by the process given in 6.1.1, to reduce the weight loss during storage, prevent fungal contamination and maintain proper quality.
6.1.1 The eggs shall be placed in filler flats and sprayed with a suitable mineral oil, such as liquid paraffin which shall be odourless, colourless and non-toxic. Oils of vegetable or animal origin shall not be used for spray- ing as they undergo oxidative rancidity during storage. The oil may be re-used.
6.2 The eggs intended for storage of about one month at farm level and at egg packing stations shall be stored at a temperature of 10 to 13°C and relative humidity of 75 to 80 percent.
6.3 The eggs intended for storage of about 3 months shall be stored at a temperature of 4 to 7” C and relative humidity of 75 to 80 percent.
6.4 In case fertile eggs are required to be stored, they shall be stored at a temperature of 13 to 15*5”C at relative humidity of 75 percent. The eggs may be stored at this temperature for about 7 days.
6.5 The eggs shall be properly graded before storage, and different grades shall be stored separately.
6.6 The boxes containing eggs may be stocked in shelves provided in a cold store.
c 6.7 The eggs once brought out of the cold store shall not be sent to the cold store again.
7. POST-STORAGE CARE
7.1 Eggs stored at 4 to 7°C ( see 6.3 ) shall be placed in an ante-room having a temperature of 15.5 to 21°C for about 8 to 10 h before release for retail market.
7.2 These eggs should preferably be marketed within three days from the date of release.

IS I 6558 - 1972
8. STORAGE LIFE
8.1 It is necessary in every case that the storage should not be prolonged beyond limits suggested in 6.2, 6.3 and 6.4.
8.2 It is essential to draw samples of the eggs periodically so as to detect spoilage, if any, and to ensure efficient working of the cold store.
9. ASSESSMENT OF QUALITY OF EGGS STORED IN COLD STORAGE
9.1 External
9.1.1 Egg shell should be free from fungal contamination,
9.1.2 Loss in egg weight should not be more than 2 percent.
9.2 Candling
9.2.1 Air cell depth should not exceed 9 mm.
9.2.2 Yolk should be at the centre and not stuck to the egg shell.
9.3 On Opening
9.3.1 On opening the eggs, the vitellin membrane should not rupture.
