AB  - The objective of this study was to evaluate the sensory stability of ultra-high 
      temperature (UHT) milk subjected to different heat treatments and stored at room 
      temperature in white high density polyethylene bottles (HDPE) pigmented with 
      titanium dioxide. Two lots of 300 units each were processed, respectively, at 135 
      and 141 degrees C/10 s using indirect heating and subsequently aseptically filled 
      in an ISO class 7 clean room. These experimental lots were evaluated for 
      appearance, aroma, flavor, and overall appreciation and compared to samples of 
      commercial UHT milk purchased from local commercial stores. The time-temperature 
      combinations investigated did not affect either the acceptability or the shelf 
      life of the milk. Despite the limited light barrier properties of HDPE bottles, 
      the product contained in the package tested exhibited good stability, with a 
      shelf life ranging from 4 to 11 wk. Within this time period, the acceptability of 
      the experimental lots was similar to that of the commercial products. The results 
      achieved in this study contribute to turn the low-cost UHT system investigated 
      into a technically viable option for small-size dairy processing plants.
