Invertase
Plan sucrose inversion for confectionery, syrups and fermentation using a defined conversion endpoint.
01 / Understand the chemistry
How does invertase work?
Invertase, also called β-fructofuranosidase, releases fructose from suitable fructofuranosides. Sucrose hydrolysis produces glucose and fructose. Product distribution and any transfer reactions depend on the enzyme and conditions.
Dissolve and present sucrose
Solids content and viscosity affect mixing and access.

Invertase applications in industry and research
Start with the result you need, then choose the enzyme grade and the measurement.
Develop controlled sucrose inversion in fillings.
MEASURE SUCCESSMeasure sugar composition, texture and storage stability.
PROCESS DECISIONAccount for continued activity and product water activity.
Prepare a defined invert sugar stream.
MEASURE SUCCESSMeasure sucrose, glucose, fructose and colour.
PROCESS DECISIONControl heating and handling as well as enzyme treatment.
Investigate a pre-hydrolysis step for sucrose feedstocks.
MEASURE SUCCESSMeasure sugar consumption and culture performance.
PROCESS DECISIONSome cultures already produce invertase, so confirm the added value.
03 / Methods & measurement
How to measure invertase activity
Measure the change in sucrose and monosaccharides using chromatography or validated specific assays. Reducing-sugar assays require appropriate starting-sugar blanks.
Make a better selection
What matters when choosing a grade?
Texture changes can also arise from dilution, heating and crystallisation. Separate these effects from enzymatic conversion in a matched control.
Confirm source, grade, activity method, formulation, storage and compatibility. Use stability data for the selected preparation; an optimum measured for one protein does not define every product’s operating window.
From screening to production
Plan a useful invertase trial
Set a matched control
Use your actual material. Keep pH, temperature, residence time and mixing identical in the untreated control, so physical processing effects are separated from enzyme action.
Screen dose and time
Compare a dose ladder and take a time course. State activity units and their assay definition, and express dose against a clear feedstock or process basis.
Validate the endpoint
Measure sugar composition, texture and storage stability. Assess retained activity, downstream quality and cost per useful outcome before increasing scale.

Invertase: common selection questions
What does invertase produce?
Invertase, also called β-fructofuranosidase, releases fructose from suitable fructofuranosides. Sucrose hydrolysis produces glucose and fructose. Product distribution and any transfer reactions depend on the enzyme and conditions.
How do I test invertase for my process?
Measure the change in sucrose and monosaccharides using chromatography or validated specific assays. Reducing-sugar assays require appropriate starting-sugar blanks.
What should I check before buying invertase?
Texture changes can also arise from dilution, heating and crystallisation. Separate these effects from enzymatic conversion in a matched control. Share your feedstock, operating conditions, target outcome and required documentation when requesting a grade recommendation.
