NOVELTY - Process (P1) for producing destructured starch-based biomass, comprises: (a) providing a starch-based biomass; and (b) applying to the biomass of (a) at least one set of compression and impact forces of at least 5000 N combined with shearing forces, and a contact stress of greater than 5000 psi to produce a destructured starch-based biomass.    USE - The process is useful for producing destructured starch-based biomass, which is useful: in a feed additive composition that is useful for preparing a feed or feed stuff, and for improving a biophysical characteristic of an animal; saccharifying a composition comprising destructured starch-based biomass to produce a composition comprising glucose; for saccharifying a composition to produce a composition comprising maltose, saccharifying a composition to produce a composition comprising maltotriose, for saccharifying a composition to produce a composition comprising maltotetraose and for saccharifying a composition to produce a composition comprising maltopentaose, which are useful to produce an end of fermentation (EOF) product, which comprises ethanol (preferably 8-18 vol/vol.% ethanol), or a metabolite such as an organic acid, citric acid, lactic acid, succinic acid, monosodium glutamate, gluconic acid, sodium gluconate, calcium gluconate, potassium gluconate, glucono delta -lactone, sodium erythorbate, omega -3 fatty acid, butanol, an amino acid, lysine, itaconic acid, 1,3-propanediol, or isoprene; for producing alcohol, which is ethanol (all claimed); for producing syrups and fermentable sugars; and as an animal feed. No biological data given.    ADVANTAGE - The process: provides destructured starch-based biomass that has crystallinity that is reduced by at least 25% as compared to the provided starch-based biomass, has a processed energy equivalency of greater than 60% (claimed), has high starch content, and is readily digestible; utilizes short application of high compression, impact, and shearing forces; destructs biomass using a specific energy input that is less than 40% of the total combustible energy of the biomass; and is simple.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for:    (1) a process (P2) for producing destructured starch-based biomass, comprising: providing a portion of starch-based biomass, and the step (b) as above per se, where specific energy input in the process (P2) is less than 40% of the total combustible energy of the portion of biomass being treated;    (2) a destructured starch-based biomass obtainable by the process (P1) or (P2) comprising starch having at least 25% reduction in crystallinity as compared to provided starch-based biomass;    (3) a feed additive composition comprising the destructured starch-based biomass obtainable (e.g. obtained) by the process (P1) or (P2) in combination with at least one in-feed enzyme;    (4) a feed additive kit comprising a first container comprising the destructured starch-based biomass obtainable (e.g. obtained) by the process (P1) or (P2), a second container comprising at least one in-feed enzyme, and instructions for co-administering same;    (5) a premix comprising the feed additive composition, and at least one mineral and/or at least one vitamin;    (6) a method (M1) for improving a biophysical characteristic of an animal, comprising administering to an animal the feed additive composition or the feed or the premix;    (7) a method (M2) for preparing a feed stuff, comprising contacting a feed component with the feed additive composition;    (8) a method (M3) for saccharifying a composition comprising destructured starch-based biomass to produce a composition comprising glucose, comprising (a1) contacting the destructured starch-based biomass composition with a glucoamylase, and (b1) saccharifying the composition to produce the glucose composition;    (9) a method (M4) for saccharifying a composition comprising destructured starch-based biomass to produce a composition comprising maltose, comprising (a2) contacting the destructured starch-based biomass composition with a maltogenic alpha -amylase, and (b2) saccharifying the composition to produce the maltose composition;    (10) a method (M5) for saccharifying a composition comprising destructured starch-based biomass to produce a composition comprising maltotriose, comprising (a3) contacting a destructured starch-based biomass composition with a beta -amylase and optionally a pullulanase, and (b3) saccharifying the composition to produce the maltotriose composition;    (11) a method (M6) for saccharifying a composition comprising destructured starch-based biomass to produce a composition comprising maltotetraose, comprising (a4) contacting the destructured starch-based biomass composition with a DP4 producing alpha -amylase and optionally a pullulanase, and (b4) saccharifying the composition to produce the maltotetraose composition;    (12) a method (M7) for saccharifying a composition comprising destructured starch-based biomass to produce a composition comprising maltopentaose, comprising (a5) contacting a destructured starch-based biomass composition with a DP5 producing alpha -amylase and optionally a pullulanase, and (b5) saccharifying the composition to produce the maltopentaose composition; and    (13) a method (M8) for producing alcohol from the destructured starch-based biomass substrate by simultaneous saccharification and fermentation (SSF), comprising (a6) contacting a slurry comprising destructured starch-based biomass with an alpha -amylase, a glucoamylase, a yeast and optionally an acid stable protease, at a temperature below the starch gelatinization temperature of the destructured starch-based biomass to produce oligosaccharides fermentable by the yeast, and (b6) fermenting the oligosaccharides to produce alcohol.
