| Summary: | <p>Changes in the quality indicators of sour-milk infant drink «Biolakt» characterized by high probiotic and immunomodulatory properties and low allergic effect that were made according to the improved technology and stored in sealed-off containers at temperature (4±2) ºС during 28 days have been studied: organoleptic properties of taste and odour, consistency and appearance; physical and chemical properties – titrated acidity, ºТ; active acidity, pH units; moisture retention property, %; microbiological properties – number of living cells of mixed cultures <em>B. bifidum 1 + B. longum Я3 + B. infantis 512</em>, CFU/cm<sup>3</sup>; the most probable number of living cells of monocultures <em>L. acidophilus La-5</em>, CFU/cm<sup>3</sup>; presence of coli form bacteria in 0.3 cm<sup>3</sup>; presence of <em>Salmonella </em>in 50 cm<sup>3</sup>; biochemical properties – antioxidant activity, activity units; and maximum possible content of malondialdehyde at complete oxidation of the product ingredients, mg/100 g. It is proved that under indicated conditions in the course of 24 days the studied samples of target products possess high organoleptic and standardized for sour-milk infant drinks physical, chemical, biochemical and microbiological indicators and are, also, characterized by high content of probiotics: (0.43…8.60)∙10<sup>9</sup> and (0.25…1.10)∙10<sup>9</sup> CFU/cm<sup>3</sup> of living cells of bifidus bacteria and lactobacilli, accordingly.</p><p>It has been established that the limit storage period of sour-milk infant drink «Biolakt» produced according to the improved technology and stored at temperature (4±2) ºС should not exceed 12 days with due account of the safety margin for sour-milk infant drinks (provided they are kept in sealed-off containers).</p><p>It has been proved that the target product formulas should include lactulose, polyunsaturated fatty acids omega-3 FT EU of «<em>Fortitech</em>» company (Denmark), vitamin complex FT 041081EU of «<em>Fortitech</em>» company (Denmark) and/or complex of mineral substances FT 042836EU of «<em>Fortitech</em>» company (Denmark).</p> |
