Towards the development of high quality UHT hydrolyzed-lactose milk AuthorRiccardo Bottiroli Year2020 SourcePhD Thesis LanguageEnglish Pages1-217 3212LFLUMiFugeLUMiSizer 23 more LSfoodnutritionbeveragedairyLactose is present at high concentration in mammals’ milk and it is metabolized by β-14- galactosidase (lactase) that splits the molecule into galactose and glucosewhich are then absorbed in the small intestine. Lactose intolerance is a worldwide issue with both nutritional and economic implications. Low Lactose (LL) or lactose free (LF) productsultra-high temperature hydrolyzed-lactose milk (UHLM)Changes in the UHLM physical stability was characterized by optical centrifugationinstability indexphysical stability is a major concern for the dairy industryespecially because the demixing of non-skimmed UHT milk is difficult to judge visually due to the high turbidity (C. Zhang et al.2020). ThereforeLUMiFuge was used to assess the stability behavior by recording the migration of particles under centrifugal forces. For both low fat and whole fat milkno differences were observed in the instability index between the frozen UHLMs and the ones stored at room temperature. Such finding suggests that freezing at slow-rate (-20°C) and fast-rate (-80°C) for 72 hours have no negative impact on the sedimentation/creaming stability of UHLM. On the other handthe instability indices of 1% fat UHLM were higher than for 3% fat UHLM (Supplementary Figure 1)confirming the inverse relationship between the fat globule destabilization and the fat content of the milk (LerchePiesendel& Senge2003). Instability index obtained by Lumifuge of UHLMs (with 1% and 3% fat) stored at 20°C-20°C-80°C for 72 hours.

The methodology requires minimal sample preparation (as it can measure as-received suspensions) and employs a robust measurement procedure that successfully passed the validation process. The development and validation experiments were conducted on a selection of CRMs and RMs and binary mixtures of the materials consisting of near-spherical silica particles with diameters in the range of 20 nm to 200 nm and particle mass fractions in the range of 0.1 g/kg to 10 g/kgaccording to a nested experimental design.The comparison of the validated cuvette-CLS method with the more popular disc-CLS method shows its advantages such as operational simplicityelimination of calibration with reference particlesand high throughput as up to 12 samples can be analyzed simultaneouslyREACH More details Edition13 Internal reference2278 Open publication →
