Studies in modified MRS broths indicated that the 4% supplementation level of JAI resulted in greater growth rates of LC-01 than BB-12 and LA-5. Compared to commercial chicory inulin products, the ability of JAI in improving the growth of probiotic bacteria was comparable to medium-chain inulin, but not as efficient as oligofructose. The addition of inulin powders improved the survival of probiotic LC-01 during yoghurt shelf life at 4 °C, showing ca. 1 log cycle higher number than non-supplemented yoghurt at the end of day 28. The JAI had the effect on sustaining the viability of LC-01 comparable to that of oligofructose whereas the most effective inulin powder was medium-chain chicory inulin. There was no improvement in the growth and survival of yoghurt bacteria in the presence of inulin. The numbers of ST in the experimental and control yoghurts were stable with >8 log CFU/g throughout storage time while the numbers of LB dropped below 8 log CFU/g from week 1 onwards. The post-acidification was found minimal in all yoghurts during refrigerated storage. The initial pH prior to storage ranged from 4.2 to 4.5 that dropped to 4.1–4.3 after 28 days.
