Indian StandardSPECIFICATION FOR

o. FOR EWORD0.1 This Indian Standard was adopted by the Indian StandardsInstitution on 16 July 1986, after the draft finalized by the MeatIndustry Sectional Committee had been approved by the Agriculturaland Food Products Division Council.

0.2 The demand for luncheon beef is increasing considerably, bothfrom the civilian population as well as the defence personnel. It hasconsiderable export potential also. It was, therefore, felt that thisstandard should be formulated so that suitable quality control may beexercised.

0.3 In the preparation of this standard, due consideration has beengiven to the provisions of the Prevention of Food Adulteration Act,1954, and the Rules framed thereunder. However, this standard issubject to the restrictions imposed under these, wherever applicable.

0.4 For the purpose of deciding whether a particular requirement ofthis standard is complied with, the final value, observed or calculated,expressing the result of a test or analysis, shall be rounded off inaccordance with IS : 2-1960*. The number of significant places retainedin the rounded off value should be the same as that of the specified valuein this standard.

1. SCOPE

1.1 This standard prescribes the requirements and the methods ofsampling and test for luncheon beef, canned.

2. TERMINOLOGY

2.0 For the purpose of this standard, the following definitions shallapply.

APPENDIX A( Clause 3.4.4.1 )

METHOD FOR DETERMINATION OF FILLER

A-O. PRINCIPLE

A-O.l After the sugars present in the sample are leached out, starch ishydrolyzed and estimated as invert sugars.

A-I. PROCEDURE

A-I.1 To the weighed sample add a little water and heat to 60°C. Allowto stand for some time to obtain a solution of the strach, Add about100 ml of 95 percent alcohol and centrifuge till the precipitate settlesat the bottom. Filter and wash the residue with about 50 percentalcohol until the filtrate gives no test for sugars, when tested as perdetails given below.

A-I.I.t To a few ml of the filtrate in a small narrow test tube, add 2drops of 10 percent alcoholic solution of alpha-naphthol. Allow 1 mlof pure concentrated sulphuric acid to flow slowly down the side of thetest tube so as to form a layer beneath the aqueous solution. If sugars arepresent, a red ring will appear within a few seconds at the junction ofthe two layers.

A-l.2 Transfer the residue to a 500 ml Erlenmeyer flask with about100 ml of water. Add 20 ml of concentrated hydrochloric acid, place

B-l.2 Distillation Assembly - The assembly consists of a roundbottomed flask of 1 000 ml capacity fitted with a rubber stopper throughwhich passes one end of the connecting bulb tube. The other end ofthe bulb tube is connected to the condenser which is attached by meansof a rubber tube to a dip tube which dips into a known quantity ofstandard sulphuric acid contained in a beaker of 250-ml capacity.

B-2.9 Sodium Hydroxide SolutioB - Dissolve approximately 450 g orsodium hydroxide in SSO ml of distilled water. Cool and filter throughglass wool, if necessary.

B-3. PROCEDUREB-3.1 DeterminatioD of Lean Meat Content

B-3.1.1 Accurately weigh about 2 g of the test sample and transferit to the Kjeldahl digestion flask. Add JO to 15 g of potassiumsulphate (or anhydrous sodium sulphate), 0·1 to 0-3 g of mercuricoxide and 15 to 25 ml of concentrated sulphuric acid. Heat gentlyuntil frothing ceases and then heat strongly until the solution becomesclear and continue the digestion for at least 30 minutes longer ( about3 hours are required for complete digestion). Cool, and dilute withabout 250 ml of distilled water. Cool to room temperature, add a fewglass beads and run 50 ml of the sodium hydroxide solution down theside of the flask so that it forms a separate layer and does not mixwith the acid solution at once.

Connect to the distillation assembly, mix the contents of the flaskby gently swirling and then distil off the amonia in about 250 ml ofdistillate into an Erlenmeyer flask containing a known volume ofexcess of standard sulphuric acid. Titrate the excess acid in theErlenmeyer flask with the standard sodium hydroxide solution using3 to 4 drops of the methyl red-methylene blue indicator solution.

B-3.1.2 Carry out a blank determination using all the reagents in thesame quantities but without the material to be tested.
