SECTION II - LINES WITH OTHER CLASSES AND WITHIN THIS CLASS
Processes generally for the hydrolysis of carbohydrates, including
their conversion to sugar by other than biochemical hydrolysis,
where the process either stops with such conversion or is followed
by the steps of purification, concentration, or crystallization
of the sugar or sugar solution thereby produced, are found in this
class. Processes of hydrolysis of carbohydrates which include the
action of diastase or other biochemical steps are for the most part
in Class 435, Chemistry: Molecular Biology and Microbiology, subclasses
93, and 98-105, and are included here only when such hydrolysis
is followed by steps of concentration, purification, or treatment (such
as crystallization) to make a sugar or syrup. Hydrolysis of carbohydrates
to sugar by any method when followed by alcoholic fermentation or
when directed specially to preparation for alcoholic fermentation
is in Class 435. The chemical manufacture or synthesis of sugar
or carbohydrates by any other process than that of hydrolysis is
not included in this class. Molecular rearrangement of one carbohydrate
to form any other carbohydrate is excluded. For such processes search
Class 260, Chemistry of Carbon Compounds.
Process of making sugar foods, per se, or the sugars combined
with a preservative, including hydrolysis of starch to sugar, are
placed in this class. Foods which contain sugars combined with nonsugars
(other than a preservative) and processes of making them are in
Class 426, Food or Edible Material: Processes, Compositions, and
Products.
Mere processes of making, separating, or purifying sugars,
starches, celluloses, or other carbohydrates, by operations that
include fermentations, and compositions and apparatus that are specialized
for use therein, and processes of making such compositions for such
use, are classified in Class 435, Chemistry: Molecular Biology and
Microbiology.
