摘要:
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.
摘要:
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 comprises 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 comprise a food grade fluid and a food grade abrasive, for example, air and salt, respectively.
摘要:
Methods, apparatuses, and systems for removing the peels/skins from agricultural produce, such as fruits and vegetables, are disclosed. The peel and/or the connection between the peel and the flesh of the produce can be at least partially destroyed by a caustic fluid and/or steam. Once the peel has been sufficiently loosened from the flesh, forced air may be applied to the surface of the produce to remove the loosened peel and any residual caustic fluid. Using air to remove the loosened peel instead of the conventional use of water significantly reduces the freshwater requirements and substantially reduces the quantity of wastewater discharge with very low concentration of contaminants. The peels, caustic fluid, and water can be collected and separated, after which the peels can be neutralized and fed to livestock, used as fertilizer, or used for pectin production, and the caustic fluid and residual water can recycled into the system.
摘要:
A tomato lye applicator (10) including a pre-heat apparatus (14) mounted to the shell (16) of applicator (10) for pre-heating tomatoes prior to submerging in a lye solution bath (28). Pre-heat apparatus (14) includes a conveyor (42) and steam connections (64, 66) for heating enclosure (40) so that as tomatoes move from inlet (18) to applicator inlet (20), the skins of the tomatoes are pre-heated an amount sufficient to enhance skin loosening by the lye solution.
摘要:
Novel process for peeling fruits and vegetables which yields maximum skin removal coupled with minimum loss of flesh. The fruit or vegetable is contacted with an aqueous dispersion of a 3-18 carbon carboxylic acid at elevated temperatures for a time sufficient to loosen the peel, which can then be removed by mechanical action.
摘要:
Fruits or vegetables are peeled by immersing a fruit or vegetable in an aqueous solution of an alkali to which is added (a) at least one member selected from polyoxyethylene sorbitan fatty acid esters and sucrose fatty acid esters having an HLB value higher than 9 and (b) at least one member selected from glycerin fatty acid esters, sorbitan fatty acid esters, propylene glycol fatty acid esters and sucrose fatty acid esters having an HLB not higher than 9.
