Nucleation intensification in the ice cream production

Production of Ice Nucleation Deficient (Ice-) Mutants of the Epiphytic Strains of Erwinia herbicola

To mutate the Ice Nucleation Active (INA) gene in Erwinia herbicola strains, Tn-5 transposon carried by Psup2021 plasmid was used. This plasmid was transferred to the bacterial cells by electroporation. Electrotransformation was carried out for 2.5 ms at 1800 v and 1 mm distance between the electrodes. Polymerase chain reaction was used for determination of presence or loss of INA gene, using a...

Production of Synbiotic Ice Cream

The aim of this study was to evaluate the survivability of three probiotic strains Lactobacillus plantarum, Lactobacillus casei and Bifidobaterium bifidum in ice cream using microencapsulation by calcium alginate and whey protein concentrate. Also, the effect of different prebiotics (inulin, lactulose and Fructooligosaccharides) was studied. Six types of synbiotic ice cream containing free and ...

Bacterial Standards for Ice-Cream

Within the last two or three years, the manufacture and consumption of ice-cream in the city of Calcutta have enormously increased. Numerous small and large cafes and restaurants have sprung up, and most of them are preparing and supplying ice-cream to their customers, civil and military. The production of ice-cream by large scale manufacturing companies has gone up tenfold and more, and the ic...
