Measurement of valve oxygen diffusion for bag‐in‐box applications under three possible ambient conditions

Changes on Enological Parameters of White Wine Packaged in Bag‐in‐Box during Secondary Shelf Life

“…Temperature is well known to influence the oxygen permeability of thermoplastic polymers (Robertson 2005). As shown in Table 2, the OTR data of the tested BIB#1 packages indicate that the OTR of the BIB package increased with increasing temperature, which was in agreement with other published findings (Doyon and others 1995). The variation of OTR values among the wine packages may have contributed to the differences in the enological parameters observed for the replicate samples.…”

“…To preserve these characteristics, the exposure of white wine to O 2 needs to be minimized during fermentation, bottling, and storage. Due to its large volume capacity (typically 3 to 5 L), BIB white wine is usually consumed over an extended time after the package is opened, during which its secondary shelf life can be affected by potential temperature abuse and oxygen ingress through the dispensing fitment (Doyon and others 1995), which may accelerate the degradation of freshness/fruity traits and induce browning reactions (Presa‐Owens and Noble 1997).…”

Canadian bag‐in‐box wine under distribution channel abuse: material fatigue, flexing simulation and total closure/spout leakage investigation

“…A schematic of distribution of the gases and flow in capture cells was described previously. 1 The physical structure and components of the stainless steel capture cells is presented in Figure 4A …”

“…5 There were a total of 32 experimental units. The Q 10 of total permeation and leakage was estimated following the equation described by Doyon et al 1 Regression analysis for flex cracking data was done with a TableCurve (SPSS Inc., Chicago, IL, USA). Analysis of variance and regression on route age, DZFE and distance were performed using the SAS (Cary, NC, USA) statistical package.…”

“…The BIB material, excluding these two tap components, must have permeation and leakage below 0.5 cm 3 /m 2 ·d·atm at 30°C to comply with SAQ's film specifications. Previous work by Doyon et al 1 has shown the capability of a new glass capture cell design to measure O 2 permeation/leakage of taps. Improvements were required to reduce or eliminate the application of glue or cement for air-tightness that cause delays in procedural testing of the tap and additional costs for testing.…”
