NOVELTY - Producing plant oil, comprises mechanically disrupting a plant material (e.g. a plant seed, or plant seed cake), digesting the disrupted material in an aqueous medium with a carbohydrase and separating the product into an oil fraction (e.g. a liquid plant oil fraction), a solids fraction (e.g. a proteinaceous fraction) and an aqueous fraction (e.g. a water-soluble saccharide fraction).    USE - The plant oil and/or plant protein is useful in an animal feed e.g. a mammalian land-animal feed, a poultry feed or preferably an aquaculture feed including a vertebrated fish feed and a salmonid feed. The plant oil is useful in a mineral oil-containing hydraulic fluid and as an insulating oil or a dielectric coolant e.g. as a transformer. The oil or alcohol is useful as a fuel or fuel additive. The seed shell fragments produced by the process is useful as animal feed e.g. a feed for a land-based animal, preferably a human or another mammal such as pig, cow, sheep, goat, horse, or poultry (all claimed). No biological data given.    ADVANTAGE - The plant oil has: significantly less oxidation compared to other vegetable oils; low phosphorus content (less than 10 (preferably less than 4) parts per million (ppm)); low sulfur content (less than 20 (preferably less than) 9 ppm); low water content (less than 0.2 (preferably less than 0.07)%); acid value of less than 1, preferably less than 0.7; a lower viscosity; and dielectric strength of at least 48. The plant oil exhibits good thermal properties and a high fire point/flash point compared to traditional fossil oils.    DETAILED DESCRIPTION - Producing plant oil, comprises mechanically disrupting a plant material (e.g. a plant seed, plant seed core, or plant seed cake), digesting the disrupted material in an aqueous medium with a carbohydrase and separating the product into an oil fraction (e.g. a liquid plant oil fraction), a solids fraction (e.g. a proteinaceous fraction) and an aqueous fraction (e.g. a water-soluble saccharide fraction), where the process comprises one or more features including (a) before, during or within ten minutes of onset of the core disruption step, the seeds are subjected to an enzyme-denaturing heat treatment step, (b) the process is continuous, (c) the plant material is plant seed cake, and (d) the plant seed is seed of Camelina sativa, B. juncea, B. nigra, grape, Indian jujube, palm, soybean, sunflower, safflower, walnut, groundnut, or apricot. INDEPENDENT CLAIMS are included for:    (1) a hydraulic fluid comprising a plant oil produced by a process preferably a rapeseed oil, and a mineral oil;    (2) an animal feed e.g. a mammalian land-animal feed, a poultry feed or, preferably an aquaculture feed including a vertebrated fish feed and a salmonid feed, comprising protein and lipid, where the lipid comprises the plant oil produced by the process, preferably at least 10 wt.% of the lipid content and/or the protein comprises a protein produced by a process, preferably at least 10 wt.% of the protein content;    (3) a glucosinolate composition comprising a glucosinolate extracted from a water-soluble saccharide composition produced by a process;    (4) an animal feed e.g. a feed for a land-based animal, preferably a human or another mammal such as pig, cow, sheep, goat, horse, or poultry, comprising seed shell fragments produced by the process, e.g. as up to 25 wt.%, preferably 1-10 wt.% of the feed; and    (5) an insulating oil or a dielectric coolant, e.g. a transformer oil, comprising the plant oil produced by a process.
