Pigmented bottle battles milk oxidation

A new FlavorTight™ bottle that adds a white color concentrate to high-density polyethylene helps prevent oxidation in Dean Foods’ Land O’Lakes-brand ½- and 1-gal sizes of milk. Introduced in August into seven Midwest states, the bottles are used for 14 total SKUs.

Suggested retail prices range from $3 to $3.50 for the 1-gal size; $1.50 to $2 for the ½-gal versions. Refrigerated shelf life remains at about 20 days.

What’s different is that “the pigment [is] three times better at blocking out light than our traditional translucent milk containers,” says Pat Graiziger, vice president of sales and marketing for Dean Foods North Central. Oxidation in milks begins after four minutes of direct ultraviolet sunlight, and in four hours when exposed to fluorescent light. This chemical process causes an “off” flavor that intensifies with time. It also breaks down vitamins.
