Organic phosphorus compounds, primarily inositolhexaphosphates (probably more than 50% of all organic phosphates), occiu in soils. The parent cyclic polyol, inositol, exists in numerous stereoisomeric configurations, of which myo-, scyllo-, neo-, and cZZ-inositol have been isolated from soils as phosphate esters. The hexaphosphate of myoinositol (myo-IHP), phytic acid, occurs in plant tissues. It often occurs as phytin, the calcium magnesium salt. Esters of myo-IHP are readily adsorbed in acidic soil solution by clay minerals and finely divided hydrated oxides of iron and aluminum. Organic sulfur compounds present in soils probably occur primarily as amino acids—e.g., cysteine, cystine, and methionine.

Alternatives to Sulfites. To meet the needs of the food industry for alternatives to sulfites, a number of browning inhibitor formulations have been marketed. These products are mostly combinations of AA, EA, or their sodium salts with such adjuncts as citric acid, sodium or calcium chloride, phosphates, cysteine and potassium sorbate (23-29). Commercial browning inhibitor formulations vary widely both in AA or EA content and in recommended use levels (Sapers, G. M., Eastern Regional Research Center, Philadelphia, PA, unpublished data). These sulfite substitutes are considered to be less effective than sulfites because they do not penetrate as well into the cellular matrix (11). Furthermore, AA is easily oxidized by endogenous enzymes (18) or by autoxidation, and in the course of its intended role as a browning inhibitor, may fall into a concentration range where it exerts pro-oxidant effects (30). To enhance their effectiveness, the sulfite substitutes may be used in conjunction with modified atmosphere or vacuum packaging (29,31).
