Why stabilisers are critical in evaporated milk production? Evaporated milk undergoes intense thermal processing, which can lead to fat separation, protein aggregation, increased viscosity over time, lactose crystallisation and undesirable texture or mouthfeel.
According to the International Dairy Federation, up to 25% of evaporated milk batches are rejected or downgraded due to instability, most often caused by inadequate stabilisation.
A 2022 Journal of Dairy Science study found that viscosity in unstabilised Retort and UHT evaporated milk can vary by up to 35% over six months, while stabilized formulations achieved over 90% improvement in physical stability, preserving smoothness and emulsion integrity during long-term storage.
