A citrus fruit manufacturing method includes a pretreatment step of partly removing an outer skin of a citrus fruit and/or making a cut into the outer skin, an enzyme solution impregnation step of immersing the pretreated citrus fruit into an enzyme solution which can decompose the outer skin and is temperature adjusted to normal temperature or 10° C. to 40° C., in a decompression space, an outer skin decomposition and removal step of decomposing and removing the outer skin from the impregnated citrus fruit in the enzyme solution, a finishing process step of washing with water the decomposed and removed citrus fruit of the outer skin, and an inner skin decomposition and removal step of separating the spherical citrus fruit washed with water and peeled off only the outer skin into juice vesicles with an inner skin to immerse into the enzyme solution and decomposing and removing the inner skin.

The invention relates to process for converting berry and/or fruit materials to fractions comprising bioactive compounds, said process comprising the steps, where at least one berry material or fruit material selected from berries, fruits, by-products, side streams and waste materials originating from berries or fruits, and any combinations thereof is sieved whereby a seed fraction is separated from a skin fraction, the seed fraction is subjected to sanding and a seed coat fraction comprising surface layer of the seeds and a sanded seed fraction comprising the sanded seeds are obtained.

A method and apparatus for causing attrition to an outer surface of a food product to provide a removed portion of the food product and a remainder of the food product. In a first aspect, an abrasive stream contacts the outer surface of the food product, thereby separating at least a portion of the outer surface of the food product from the remainder of the food product to provide the removed portion of the food product. In a second aspect, the apparatus includes a product positioner to position the food product in an attrition zone and a nozzle for discharging the abrasive stream into contact with the food product in the attrition zone. The abrasive stream can be food grade and can include a food grade fluid and a food grade abrasive, for example, air and salt, respectively.
