개요

High-fructose corn syrup (HFCS) is produced by enzymatic isomerization of glucose derived from corn starch. The three-enzyme process converts cornstarch to a syrup with sweetness equivalent to sucrose. HFCS-55 (55% fructose) is the primary sweetener in American soft drinks, while HFCS-42 is used in baked goods and processed foods. The US produces approximately 8 million tons annually, representing a major agricultural commodity product.

화학 공정

Corn starch slurry is liquefied with alpha-amylase at 95-105 degrees C to produce dextrins. Glucoamylase converts dextrins to glucose at 60 degrees C and pH 4.5. The glucose syrup is then passed through immobilized glucose isomerase columns at 55-60 degrees C to convert approximately 42% of glucose to fructose (HFCS-42). HFCS-55 is produced by chromatographic enrichment.

(C₆H₁₀O₅)ₙ + nH₂O →[alpha-amylase] maltodextrins →[glucoamylase] nC₆H₁₂O₆ (glucose)
C₆H₁₂O₆ (glucose) ⇌[glucose isomerase] C₆H₁₂O₆ (fructose) (equilibrium ~42% fructose)

원자재

  • Corn starch ((C₆H₁₀O₅)ₙ) — Corn wet milling (Substrate)
  • Alpha-amylase (enzyme) — Bacillus licheniformis fermentation (Starch liquefaction)
  • Glucoamylase (enzyme) — Aspergillus niger fermentation (Saccharification)
  • Glucose isomerase (enzyme) — Streptomyces murinus, immobilized (Glucose-to-fructose conversion)

최종 제품

  • HFCS-42 (42% fructose) — Baked goods, cereals, processed foods (71% dry solids)
  • HFCS-55 (55% fructose) — Soft drinks and beverages (77% dry solids, same sweetness as sucrose)

Environmental Impact

Corn farming for HFCS production contributes to fertilizer runoff and water pollution. The enzymatic process itself is relatively clean with low chemical waste. Spent enzyme columns and activated carbon require disposal. Energy usage for evaporation is significant.
