An unaerated ice confection in the form of thin, unsupported, discrete pieces which are stable during packaging, storage and distribution wherein the ice confection comprises an antifreeze protein and has the following mechanical properties; .DELTA. modulus/original modulus.gtoreq.0.4, and/or .DELTA. strength/original strength.gtoreq.0.4; providing that when .DELTA. modulus/original modulus.ltoreq.6.0, .DELTA. modulus.gtoreq.50 MPa, and/or when .DELTA. strength/original strength.ltoreq.2.0, .DELTA. strength.gtoreq.0.2 MPa.
A process for the manufacture of a frozen food product comprising antifreeze peptides, wherein the process comprises one or more of the following steps; (i) a (pre-) freezing) step which is a nucleation dominated freezing process; (ii) a (post-) compaction step using a screw extruder or a (piston) compactor; The invention aims at providing the food manufacturer with a greater flexibility for using antifreeze peptide material in frozen food products when aiming to obtain a product with improved recrystallization properties in combination with a good texture. In particular it has been found that the texture of frozen food products containing antifreeze peptides can markedly be improved by carefully controlling its production method.
Use of a polypeptide or protein with amino acid sequence corresponding substantially to AFP-type III HPLC 12 as additive in a product for improvement of said product, said improvement residing in improved properties of modification of ice crystal growth processes influencing size and shape characteristics of ice in particular in regrowth thereby e.g. minimizing potential freezing damage e.g. by preventing or inhibiting ice recrystallization of the product upon freezing, said use occurring in a manner known per se for anti freeze peptides to obtain higher specific modification activity in particular antifreeze activity than obtainable with the same amount of Winter Flounder AFP.
Products that are aerated multiphase systems containing an aqueous continuous fluid phase which may include solutes thus forming an aqueous syrup and disperse phases like gas/air cells, water ice crystals and solid/semi-solid fat globules or aggregates thereof, whereas the disperse phases are that finely structured that their mean diameters are below phase specific critical maximum values and thereby generate a most preferred by consumers, full rich silky-creamy mouth feel at much lower fat content than usual in conventional related products like premium and super premium ice creams.
