physical degradation during traditional thermal pasteurization. With all the
aforementioned achievements of DPCO2 processing and the availability of a
commercial scale system, the process is still not being widely used by the fresh
squeezed juice industry. The major hurdle that prevents the BTF system from
becoming the common method of application in the juice industry is cost. The
DPCO2 per gallon cost is higher than that of the heat pasteurization, because the
cost of the initial BTF system is capital-intensive and its daily operational costs
for utilities are expensive. Aspects of overcoming the cost hurdle include
development of more economic systems or systems with larger scale and higher
utilization rates.
