Confectionery applications Acidulant blends (2-4 acidulants) > sourness additive effect > flavor improvement > sequential release of sourness Buffered systems > retard sucrose inversion > control gel texture
Use Citric/Malic blends to enhance sourness and fruit flavours: demo Tangerine Sours: Sugar, corn syrup, citric acid, malic acid, natural flavor, carnauba wax, red 40, yellow 5
Minimise moisture absorption in hard candy several ways moisture absorption Minimise initial moisture level Increase ph with buffer salts Rapidly reduce temperature after adding acids Control storage and handling conditions

Malic Acid in hard candy Batch process: use granular Malic Acid Continuous process: NaLactate/Malic solution
NaLactate/Malic solution 77% w/w of 35% w/w Malic Acid 23% w/w of 60% w/w Sodium Lactate First prepare 35% w/w Malic Acid solution; then add Sodium Lactate solution Solution composition (% w/w): Water: 59.2 Malic Acid: 27.0 Sodium Lactate: 13.8
Use Citric/Malic blends to enhance sourness and fruit flavours Tangerine Sours: Sugar, corn syrup, citric acid, malic acid, natural flavor, carnauba wax, red 40, yellow 5
Use acidulant combinations in chewing gum: demo Grapermelon: sugar, gum base, corn syrup, modified corn starch, natural and artificial flavors, glycerol, malic acid, citric acid, softeners, fumaric acid, aspartame, shellac, color added, sorbitol, acesulfame K, blue 2 lake, red 40, carnauba wax, bha
Chewing gum trends Production cost of chewing gum pellets lower due to: >compressible chewing gum powder >briquetting process Wrigley decided to include high intensity sweeteners in ALL chewing gum products Personal care chewing gum (breath freshening, dental care, nicotine, etc.)
Use acidulants in chewing gum to: Stimulate saliva flow Enhance fruit flavors (Malic Acid) Prolong sourness (esp. with APM, SUC) > Fumaric Acid slow dissolution > acidulant combinations > encapsulated acidulants

Use acidulant combinations in chewing gum Grapermelon: sugar, gum base, corn syrup, modified corn starch, natural and artificial flavors, glycerol, malic acid, citric acid, softeners, fumaric acid, aspartame, shellac, color added, sorbitol, acesulfame K, blue 2 lake, red 40, carnauba wax, bha
Confectionery jellies Minimize acid hydrolysis of hydrocolloids > add acid last > buffer systems Enhance fruit flavors Control gel texture > buffer systems

Malic Acid in sugar-free compressed tablet: demo Orange Blitz: Sorbitol, malic acid, calcium stearate, natural and artificial flavors, sucralose
Compressed confectionery tablets: acidulant objectives Maximum sourness per unit weight Enhance fruit flavors Achieve sweet/sour balance (Aspartame, Sucralose) Tablet lubrication
Improve tablet lubrication with Malic and Fumaric Acids Greater hydrophobicity: - less tablet adhesion - less brittle tablet - higher production yield Log(octanol/water partition coefficient) of undissociated organic acids (Leo et al., 1971) Benzoic 1.87 Sorbic 1.70 Fumaric 0.28 Propionic 0.25 Adipic 0.08 Acetic -0.31 Lactic -0.62 Malic -1.26 Citric -1.72 Tartaric -2.02
Malic Acid in sugar-free compressed tablet Lemon Lift: sweeteners (sorbitol, aspartame, acesulfame K), malic acid, flavorings, release agent (calcium stearate), guarana (0.1%), colour (E104)
