Use of pectinase in the production of fruit juice.
             In industry, the enzyme pectinase is used in the production of fruit juices. This is mainly because the enzyme breaks down pectins, which are found in plant cell walls, increasing the yield of juice from the fruits by 20% and only 150cm³ may be required for a tonne of apples. Each year, tonnes of apple juice is produced and using the enzyme pectinase enables the business to continue running as it saves on costs. The diagram shows where the pectin comes from in a plant. It is gel like and forms the middle lamella layer which sticks adjacent cells together.
             Methods and Materials: See practical guide
             Table 1 shows the amount of apple juice produced in each cylinder, pectinase present or control.
             Time (mins) Pectinase (ml) Control (ml)
             The results show that the cylinder which contained pectinase produced more apple juice than the cylinder with just water in it.
             The results show that the cylinder with pectinase used, produces much more apple juice than the control. This shows that the enzyme pectinase has a great effect on the volume of juice produced. During the reaction, pectinase breaks down pectin in to smaller soluble molecules, resulting in more juice production.
             Pectin is a polysaccharide that is present in and between plant cells which causes two adjacent plant cells to stick together. Pectin is broken down by pectinase. Pectinase is actually a group of enzymes which break down various structural components of pectin. Industry uses pectinase to increase the yield of apples cranberries and grape juices. Pectinase increases yield by breaking down pectin holding the juice in. At first the juice appears cloudy, pectinase then makes the juice clearer by breaking down the bits of cell whi
