Improvement of Starch Digestion Using α-Amylase Entrapped in Pectin-Polyvinyl Alcohol Blend

Table 1

Composition of the reactors in trials of starch hydrolysis in artificial bovine rumen (in vitro).

Reactor	Bovine rumen (mL)	Ruminal buffer solution (mL)	Corn grain (g)	Pectin/PVA/amylase (g)
				0.25%	1.25%
0.25%	400	1600	80	20	0
1.25%	400	1600	80	0	20
Standard	400	1600	80	0	0

Ruminal buffer composition (g L⁻¹): 10 g KH₂PO₄, 0.5 g MgSO₄ 7 H₂O, 0.5 g NaCl, 0.1 g CaCl₂ 2 H₂O, 0.5 g Urea, 15 g Na₂CO₃, and 1.0 g Na₂S 9 H₂O.
