interesting article (dated) on Jasper's mfg process......

Details of the process

The 3,600 gal. per hour processing system at Jasper Products heats low-acid beverages with super-heated water to 280¿F for at least two seconds. Product is rapidly cooled to 45¿F, homogenized and stored in aseptic silos for filling into sterile bottles. This process is milder than earlier aseptic systems and helps reduce the development of off-flavors. However, the treatment is potent enough to achieve commercial sterility.

Under sterile conditions using a HEPA air filtration system, a blow molder produces bottles with closed tops. Bottles are composed of three HDPE layers. The two exterior layers of ordinary HDPE enclose an interior black light-blocking HDPE layer. Bottles remain sealed until just before filling. This assists with cleanliness and structural integrity.

When it is time for filling, in a clean room that also uses HEPA air filters, bottle tops are cut off and bottles are sterilized with hydrogen peroxide vapor, a step required by FDA for aseptic processing. Upon filling, bottles are quickly hermetically sealed with sterilized foil seals.

“The system at Jasper Products fills about 200 bottles per minute,” says Kellar. “This is about twice the speed of the only other FDA-approved commercial aseptic plastic bottling system.”
