Modified directly with reducing sugars

Phenol-formaldehyde resins modified directly with reducing sugars successfully bond wood veneers at neutral conditions. The dry- and wet-shear strengths of two-ply panels bonded with xylose-modified resins are not adversely affected until the amount of xylose is increased to between 0.6 and 1.0 moles xylose per mole of phenol (Figure 2). However, even resin with 2 moles xylose per mole of... [Pg.356]

Extract ability. About 60 to 70% of the total modifier added is extractable from resins cured under basic conditions and modified with alditols and methyl glycosides (2). In contrast, only about 0 to 20% of the xylose and prehydrolysate is extractable from samples of cured resin modified with 0.6 moles of either modifier per mole of phenol. Approximately 20 to 30% of xylitol (II), methyl xyloside (III), or glucose (IV) is extractable from neutral resins modified with these carbohydrates, indicating that neutral resins incorporate the carbohydrate more effectively than resins formulated and cured under basic conditions. In addition, free reducing sugars can be used directly. [Pg.361]

The Middle Notes are based on reaction flavourings to impart specific complex roasted, meaty and smoky notes roasted chicken, boiled beef, smoked ham. They improve the overall taste with a general meaty background and a good mouthfeeling. Meaty middle notes are often based on the reaction of vitamin Bl, cystein and reducing sugars. Fat included in the reaction modifies the product into a specific animal direction chicken, beef, mutton, pork. [Pg.429]
