Production process of sodium gluconate, in terms of culture
mutagenesis of Aspergillus niger key research done to achieve a high
concentration, low nutrients, fat at high temperatures Fermentation
production, extraction of decolorization in the sodium gluconate
replaced by granular activated carbon powder activated carbon,
evaporation and crystallization processes in the adoption of new The
equipment and technology to improve product yield and product quality.
The results show that: the amount of substrate concentration on the
conversion rate of sugar and acid substances not significant, the
optimum temperature 40 ℃, the optimum pH 6.5, ventilation 10L/min,
reaction time 80h. Orthogonal test for sodium gluconate preparation
process optimization, optimal results are: substrate concentration
400g / L, temperature 40 ℃, pH 6.5, ventilation 10L/min, reaction
time 80h. Glucose oxidase I (Glucose oxidase, referred to as GOD),
which, named as β-D-glucose oxidoreductase (EC1.1.3.4), which can
catalyze highly specific β-D-glucose with oxygen in the air the
reaction, the glucose is oxidized to gluconic acid and hydrogen
peroxide.
The enzyme is widely distributed in animals, plants and
microorganisms, mainly industrial use Aspergillus niger and
Penicillium strains for sodium gluconate. As a new enzyme
preparation, because GOD has to glucose, oxygen, sterilization and
other features, and safe, non-toxic side effects, so the processing
has fresh food, medicine and other widely used. In 1999, the Ministry
of Agriculture, as it allows the use of 12 kinds of feed enzyme
additives. Rigid spawned the demand for housing continues digging
into the sky over the estate, construction progress, process
requirements are becoming a mandatory requirement of the major real
estate. Weather gradually turned hot summer weather, there will be
construction of concrete setting time interval becomes shorter, which
are required for each construction team to solve the problem.
Condensation concrete with cement admixture mainly adaptability, and
temperature, and other factors outside sodium gluconate the residual material. From
mixing cement with water until the grout begins to lose time required
for plasticity. Final setting time from mixing cement with water
starting to grout completely lost the strength of plastic and the
time required to start production. Setting time of cement has great
significance in the construction, the initial setting time should not
be too short, final setting time not too long.
Construction process of this problem and the problem is not usually
treated using sodium gluconate. Gluconate South and concrete
admixture, water reducer and retarder role exists, you can adjust
the plasticity and strength of the concrete. Sodium gluconate can
significantly delay the start time and the end of the solidification
of the concrete. Logarithm of the initial solidification time and the
proportional relationship with the amount added, the amount dosed to
double to ten times the initial solidification time delay, which
makes the work time from few hours to a few days and detract from the
strength. Especially hot days and a longer time to be placed, this is
an important advantage.
