Claim:
1. A beverage preservative system comprising: an N-bis-phosphonic acid or alkali metal salt thereof; a biodegradable sequestrant at a concentration in a range of 10 ppm to 120 ppm, wherein the biodegradable sequestrant is selected from the group consisting of ethylenediamine-N,N′-disuccinic acid (EDDS), ethylenediamine-N,N′-dimalonic acid (EDDM), ethylenediamine-N,N′-diglutaric acid (EDDG) and mixtures of any of them; a weak acid selected from the group consisting of cinnamic acid, sorbic acid, their alkali metal salts, and mixtures of any of them; a reverse sequestrant selected from the group consisting of: 1,2-bis(o-aminophenoxy)ethane-N,N,N′,N′-tetraacetic acid (BAPTA), 1,2-bis(o-aminophenoxy)ethane-N,N,N′,N′-tetraacetic acid tetraacetoxymethyl ester (MAPTAM), N,N,N′,N′-tetrakis-(2-pyridylmethyl)ethylenediamine (TPEN), exochelin, pyridoxal isonicotinoyl hydrazone (PIH), 2-pyridylcarboxaldehyde isonicotinoyl hydrazone (PCIH), di-2-pyridylketone isonicotinoyl hydrazone (PKIH), 2-quinolinecarboxaldehyde isonicotinoyl hydrazone (QCIH), 2-pyridylcarboxaldehyde 2-thiophenecarboxyl hydrazone (PCTH), di-2-pyridylketone 2-thiophenecarboxyl hydrazone (PKTH), 2-quinolinecarboxaldehyde 2-thiophenecarboxyl hydrazone (QCTH), 2-pyridylcarboxaldehyde m-bromobenzoyl hydrazone (PCBBH), 2-pyridylcarboxaldehyde benzoyl hydrazone (PCBH), di-2-pyridylketone benzoyl hydrazone (PKBH), 2-quinolinecarboxaldehyde benzoyl hydrazone (QCBH), 2-pyridylcarboxaldehyde p-aminobenzoyl hydrazone (PCAH), di-2-pyridylketone p-aminobenzoyl hydrazone (PKAH), 2-quinolinecarboxaldehyde p-aminobenzoyl hydrazone (QCAH), 2-pyridylcarboxaldehyde p-hydroxylbenzoyl hydrazone (PCHH), di-2-pyridylketone p-hydroxylbenzoyl hydrazone (PKHH), 2-quinolinecarboxaldehyde p-hydroxylbenzoyl hydrazone (QCHH), 2-furoylcarboxaldehyde isonicotinoyl hydrazone (FIH), and combinations thereof; wherein the reverse sequestrant is present at a concentration of 150 ppm or less; and wherein the beverage preservative system has a pH of 5.8 or less; and wherein the beverage preservative system prevents spoilage by microorganisms in a beverage within a sealed container for a period of at least 16 weeks.
