  • The Effect of Pectinase on Apples - eHow

    Before pectinase was discovered to increase the extraction of apple juice, the food industry used pectinase to clarify apple juice. When the juice is first extracted from the fruit, it is hazy or cloudy in appearance. Adding the pectinase enzyme reduces the cloudiness of the juice. Fruit juice companies use a variety of different treatments and enzymes to maximise their yield. In this experiment students will investigate the effectiveness of these different enzymes. The enzymes used are designed to break down cells walls and release the liquids and sugars which make up the fruit. Pectinases, amylases and cellulases all break down different structures of the fruit cells ... The present work emphasized the effect of pH, temperature and kinetics of pectinase enzyme which is used in food and braveries. It was carried with solid-state fermentation using soil as substrate using Aspergillus niger. The organism was subjected to different conditions such as pH, temperature and kinetics of enzyme activity. It was

    video lab report. Pectinase; A Juice Making Enzyme For Your Kitchen (& Brewery If You Are Into Wine Making) - Duration: 4:42. Hertfordshire Allotment Life 1,193 views Both beakers need to be placed in a waterbath at about 40°C and left for 15 minutes or so. After that time, students should be able to see that the beaker with the pectinase has extracted more juice from the apple than the one containing only water. how old is the pectinase? And is the apple juice artificially made cloudy? You could try the "How much juice out of an apple" experiment which works a bit better (you put squished up bits of apple with different concentrations of pectinase (0, 5% & 10%), mix well & and filter into a measuring cylinder).

    Place beaker contents into a funnel and filter the apple juice into the measuring cylinders. Record the volume of juice every 2 minutes and the final volume of juice. Take a sample of each juice and measure its clarity by using a colorimeter. Weigh the waste apple from each extraction. Record your results in a table with suitable headings. The type of apple must be the same because some apples may be naturally juicer than other apples. Therefore it may produce more apple juice than another apple affecting the results of the experiment. We are trying to see how the concentration of pectinase affects the amount of apple juice produced and not the type of apple. I will make sure the ... After the experiment was completed, we found that our hypothesis was wrong, as the 3ml pectinase performed worse than the 2ml pectinase. The differences were that the 3ml was 37.1ml juice produced, and that the 2ml was 41ml juice produced. It appears that the most efficient amount of enzyme would be 2ml for the amount of applesauce (56.5g ...

Therefore, pectinase enzymes are commonly used in processes involving the degradation of plant materials, such as speeding up the extraction of fruit juice from fruit, including apples and sapota. Pectinases have also been used in wine production since the 1960s.

    Conclusion - The effect of the concentration of pectinase ...

    Our hypothesis was: The more pectinase in the applesauce, the more juice produced over 10 minutes. This means our hypothesis was correct. The purpose was to see if the concentration of the pectinase had anything to do with the amount of juice produced from the applesauce. We had few errors in our experiment. We could have timed more accurately ... Reeta R. Singhania, ... Ashok Pandey, in Industrial Biorefineries & White Biotechnology, 2015. 4.1.4 Fruit Juice Industry. Enzymes are used also in fruit juice manufacturing. Addition of pectinase, xylanase, and cellulase improve the liberation of the juice from the pulp.Pectinases and amylases are used in juice clarification.

    Stand two beakers (one with pectinase and one a control) in water baths at 30, 40, and 60°C and leave for 15 to 20 minutes. Leave the final set at room temperature. Leave the final set at room temperature. Overall we were very surprised with our data. We thought that the boiled would be the most and it wouldn't tie with the room temperature. I think we had a problem in our experiment because I believe that the boiled Pectinase and apple sauce should be even lower than the heated, like the trend between the Freezed, cooled, and room temperature shows.

    One thing that the home pectin maker needs to know is that pectin levels vary from plant to plant, and from day to day, so this technique needs to be tested so you can know how much pectin to use ... Aim: My aim is to find out how different concentrations of the enzyme pectinase affect the degradation of the substrate pectin, and hence the volume of clarified apple juice produced in a specific duration of time. Their profiles cover the first 300 min and show a gradual deceleration over this time. Our experiments differ from theirs in an important aspect: we measured the liberation of reducing sugars and therefore detected not only D-galacturonic acid in itself, but also oligomers produced by endo-acting enzymes.
