Novel Technologies in Juice Processing from Opuntia spp. Fruits

Juice processing and preservation have been regarded as age-old technologies. Opuntia spp. is a fruit that grows in a semi-arid region and marginal soils and does not require much attention for cultivation. In view of the fruits’ nutritional and sensory attributes, unique juice processing technologies have been developed for higher yield and a prolonged shelf-life. The current chapter discusses the traditional juice processing methods for Opuntia juice extraction. Also, it depicts the use of novel technologies such as ultrasound, pulsed electric fields, and high hydrostatic pressure for Opuntia juice processing. The advantages of the modern processing and the current status of the juice processing from the fruits of Opuntia spp. have been elaborated in this chapter.
