METHOD FOR PRODUCTION OF MICROFIBRILLARY PECTIN-CONTAINING CELLULOSE FIBRES Russian patent published in 2013 - IPC A23L1/214 A23L1/524 C08B37/06 

FIELD: food industry.

SUBSTANCE: invention relates to production of sugar beet fibres and may be used during production of a rheological properties regulator, a structure-forming gent and a thickener in food industry. The method envisages preparation of pulp from sugar beet pressure cake or chips with cellular tissue content no less than 18%, expressed pulp addition into a solution of an alkali reagent in softened water, water duty equal to 1:15-1:40, pH equal to 10-12, water temperature being 30-60°C. One performs fractional introduction of hydrogen peroxide with gradual temperature increase. The total quality of hydrogen peroxide taken is 25 kg of hydrogen peroxide with concentration equal to 30% per 50 kg of pressure cake/chips. When the temperature is 65-70°C one performs pH correction with 5-10% water alkali solution until pH is 9.0-10.0. Then one reduces temperature to 70-90°C within 20-45 minutes. Total bleaching time is 1-3 hours. Then one performs expression using a decanter centrifuge. Then pulp is washed, first - with softened water, then - with osmotic water. After each washing stage pulp is subjected to expression. Then one supplies finely dispersed ozone with further addition of 2.0-6.0% solution of Na₂S₂O₃; one performs stirring and pulp expression using a decanter centrifuge. Then one performs repeated additional washing with further expression using a decanter centrifuge. As a result, a grainy wet product is produced.

EFFECT: production of a product wherein pectin substances are bound with a cellulose matrix which ensures good damping of fibres and a high degree of structure forming.
