官方推荐: According to Standard Methods for the Examination of Dairy Products, 16th edition, 1992, section 3.4, Sampling Raw Milk, para. 5b, “Do not expel air when folding or whirling plastic bags… Place samples immediately in a sample case with a mixture of ice ａnd water, ａnd protect them from becoming submerged in water.” Whirl-Pak® bags ａnd the Nasco Ice Chest meet both of these requirements.
