Amines & Amides

In food and beverage work this material family covers two unrelatednjobs that share an amine or amide group: amino acids used as flavor andnfortification building blocks, and aminopolycarboxylate chelants that sequesternmetal ions. The amino acids run from L-glutamic acid (the parent acid ofnthe umami enhancer MSG) through cysteine, arginine and aspartic acid. The chelantsnare the EDTA salts and DTPA. Treat the page as two toolkits under one chemicalnlabel, not one interchangeable group.

Among the chelants, the choice is about pH and binding strength. Disodium EDTA isnthe common food sequestrant for protecting color, flavor and ascorbate in dressings,nmayonnaise and canned goods; tetrasodium EDTA binds more strongly at higher pH. EDTAnsalts are permitted only in specified foods subject to use limits, so set dose againstnthe limit for your product category. Confirm regulatory status for your applicationnand jurisdiction before formulating.

On the amino-acid side, L-cysteine is the working reducing agent: it cleaves doughndisulfide bonds to cut mixing time and relax gluten, which is its main bakery function.nThat reactivity is the trade-off. Overdose and the dough turns slack and sticky, so itnis dosed in tens of parts per million, not percent. Glutamic and aspartic acids servenflavor and act as precursors; describe them by technical function, not by nutritionalnbenefit.

• Metal sequestration in dressings, mayonnaise and canned goods to protect color, flavor and ascorbate
• Dough conditioning and mixing-time reduction in bakery with L-cysteine
• Flavor systems built on glutamic and aspartic acids and their salts
• Fortification building blocks for beverage and powder blends (amino acids, magnesium aspartate)
• Process-water and CIP sequestration with higher-denticity chelants
