Pectinase - How It Affects Apples and the Amount/Rate of Juice Produced

Open Access Article. In this study, different concentrations of the inducer pectin and the carbon source glucose were evaluated as components of the culture medium for the production of pectinases by Aspergillus niger.

Furthermore, it evaluated the stability of the enzymes produced with respect to the temperature and the enzyme extract produced was tested for the clarification of strawberry juice. The experimental enzymatic extract was compared with a high-quality commercial product for the clarification of strawberry juice. Similar data were obtained for turbidity and viscosity reduction.

After the enzymatic treatment, the total phenolic compounds, total anthocyanins, and antioxidant activity were preserved. The results obtained in the present work indicate the potential of the enzymes produced for using in fruit processing. View Full-Text. Keywords: pectin; glucose; pectinases; thermo-stability; strawberry juice pectin ; glucose ; pectinases ; thermo-stability ; strawberry juice.

Funding was obtained based on the proposed study and the funding bodies had no further role in data collection, analysis, interpretation or manuscript preparation. HAE and EAE proposed the research concept, designed the experiments, provided necessary tools for experiments, experimental instructions, analyzed and interpreted the data and wrote the manuscript. ME provided the microbial strain and analyzed the data.

All authors read and approved the final manuscript. Correspondence to Hesham A. The present study was carried out to investigate the pectinase production and optimization by bacterial strain Bacillus subtilis MTCC The bacterial strain was used for pectinase enzyme production by optimizing it in various substrates, carbon sources , nitrogen sources at different pH, temperature and incubation time period. In this, study, the optimum pH, temperature and incubation period were found to be 6.
