Shelf-stable single-serve 8 fl oz organic milk boxes (typically sold in 6-packs) are available; these are UHT/ultra-pasteurized so they can be stored without refrigeration until opened.
The products are listed as pasteurized, and some are specifically labeled ultra-pasteurized (UHT). Ultra-pasteurization/UHT is used on certain items to extend shelf life and allow shelf-stable packaging.
The listings include whole milk as well as reduced-fat options—typically 2% (reduced fat) and 1% (lowfat).
Common claims include pasture-raised sourcing, no added antibiotics, no rBST/growth-hormone treatment, non-GMO feed, and USDA organic certification.
Typical highlights per 1-cup serving are about 8 g of protein (some reduced-fat jugs list 10 g), calcium, vitamin A, and added vitamin D (often around 15% of the daily value).
Some products are labeled grassfed; several list added DHA (examples show 32 mg or 50 mg per serving), and one formulation lists 1 g of prebiotics per serving.
Most list about 8 g of protein per 1-cup serving; some reduced-fat options list about 10 g per cup.
The shelf-stable boxes are single-serve 8 fl oz cartons sold in 6-packs, and each 8 fl oz serving provides about 8 g of protein (some varieties also list added DHA).
