AI Technical Summary

Technical Problem

Existing fructooligosaccharide production processes rely on refined sucrose or molasses, resulting in low utilization of agricultural and forestry by-products, difficulty in efficiently removing residual fermentable sugars, and insufficient development of the value of by-products.

Method used

Using Moringa branch water extract as raw material, oligofructose is formed through water extraction and fructosyltransferase catalysis, and residual sugar is removed by fermentation with brewer's yeast, while feed yeast is produced simultaneously.

Benefits of technology

It achieves efficient conversion of Moringa branch sugar components into fructooligosaccharides and feed yeast, reduces sugar loss, improves resource utilization, and obtains high value-added products with balanced nutritional composition and moderate activity.

Abstract

The invention discloses a coupling method for producing fructo-oligosaccharide and feed yeast by using a moringa oleifera branch aqueous extract, and belongs to the technical field of high-value utilization and biological processing of agricultural and forestry byproducts. The method comprises the following steps: carrying out water extraction on a moringa oleifera branch raw material to obtain a moringa oleifera branch water extract containing fermentable sugar; then carrying out enzymatic reaction by adopting fructosyl transferase to obtain enzyme digestion liquid containing fructo-oligosaccharide; and inoculating saccharomyces cerevisiae into the enzyme digestion liquid for fermentation, carrying out solid-liquid separation on the fermentation liquid after the fermentation is finished, taking the supernatant as a fructo-oligosaccharide solution, and centrifuging, washing and drying the thallus part to obtain the feed yeast. The method realizes efficient utilization of natural sugar components in the moringa oleifera branches and synergistic preparation of fructo-oligosaccharide and feed yeast, and has the advantages of wide raw material sources, mild process, high additional value and high resource utilization rate.
