Myers, D.J. | Fox, S.R.
Corn at 21% and 14.4% moisture was treated with two long-chain polyphosphates. The corn was wet milled using a laboratory batch steeping process soon after treatment and again after 6 months of cold storage. The phosphate content of the steep solutions, and the yields and approximate composition of the milled fractions, were determined. The steep solutions of the phosphate-treated corn were significantly higher in phosphate than those of the untreated corn, but the total solids contents of the steep solutions were not significantly different. Phosphate-treated corn had a lower starch yield than did untreated corn after 6 months of storage, but the purity of the starch was unaffected. The yields of the other products, in general, were not affected by phosphate treatment. The protein content of the gluten and fiber was greater than in phosphate-treated corn, and the oil content of the germ was lower when milled soon after treatment but not after 6 months of storage. When the phosphate treatment did affect the wet milled fractions, the effects were not dependent on the type or level of phosphate used, but were influenced in some cases by storage time.
