<p>The aim of this study was to determine the effect of two types of packaging on the change in quality indicators of pasteurised liquid egg mass. Traditionally, the shelf-life of pasteurised liquid egg mass is up to 28 days. The increase in shelf-life would increase the exportation options of this product. The liquid egg mass was pasteurised on the equipment Ovobel AR56SH; the pasteurisation process continued for 60 minutes, reaching a maximum temperature from 65 °C to 68 °C (hold time: 360 seconds). This paper focuses on two main packaging materials: high-density polyethylene (HDPE) and Tetra Rex® Bio-based. Forty-two samples of each packaging material were used to study the contents. Changes in the quality of samples during storage were estimated by measuring the total bacterial count (CFU/g) from 200 at the start of shelf-life up to 30×10<sup>5</sup> units (LVS ISO 4833-1:2014). Data in the test was explored with Anova: Single Factor statistical model and correlation method.

Changes in the quality of samples during storage were estimated by measuring the total bacterial count (CFU/g) from 200 at the start of shelf-life up to 30×105 units (LVS ISO 4833-1:2014). Data in the test was explored with Anova: Single Factor statistical model and correlation method. Data that was obtained emphasises the importance of packaging type, which could provide stable quality of ready-to-use products for a duration of up to forty-five days.
