The influence of thermal treatments in the quality of orange juice

The main objectives of the thermal treatments are:

  • Inactivation of the Pectilmetilesterasa. This is achieved by subjecting the juice to a temperature of 98 º C for 30 seconds.
  • Prevent the presence of Hidroximetilfurfural. This requires a short period of thermal treatment to be used.
  • The fundamental limitation we face is that a long treatment time increases the amount of HMF and the quality of the resulting product is reduced.

Several Steps to Extract Fruit Juice

Saturday, February 20th, 2010

  • First, the oil is removed. This process is performed without damage to the fruit. It is done to avoid unwanted flavors and the highest level of aldehydes obtained.
  • Second, the juice is extracted. The technology used to cut and squeeze the orange and very different from the In-line systems. The HRS process does not damage the skin and thus prevents contamination of the juice.
  • Third: the juice is separated from the peel and seeds. With this process we reduce the bitter flavor, getting a low reading speed fiber and a low viscosity in the NFC.

The resulting juice has a minimal content of the bitter flavor, a pleasant color, minimum natural oil content and an increase in the number of intact cells juice. Limo Nina The content is also reduced.

The average cell size in the pulp is increased by a higher percentage of floating pulp. We must also stress that the process does not use water in the extraction process, the optimized power consumption and contaminants in the wastewater are minimized.
