- the present invention relates to a plant-based seafood product, to a method for preparing a plant-based seafood product to the use of a composition as plant-based seafood product.
- the object underlying the present invention is therefore to make available a plant-based seafood product that properly addresses the afore-mentioned need.
- a further object of the present invention is to provide a method for preparing a plant-based seafood product.
- a further object of the invention is to provide a use of a composition as plant- based seafood product.
- the invention relates to a plant-based seafood product comprising or consisting of the following ingredients: at least one protein and/or at least one protein concentrate and/or at least one protein isolate, at least one fiber component, at least one solid lipid and/or at least one liquid lipid, at least one hydrocolloid component and water.
- the plant-based seafood product according to the present invention is preferably a structured and/or textured plant-based seafood product.
- sea life in particular animal sea life, preferably fish, and/or parts, particularly in the form of a fillet or roe, thereof.
- plant-based seafood product in particular “structured and/or textured plant-based seafood product”, as used according to the present invention refers to a product comprising or consisting of plant or vegetable ingredients, i.e. ingredients being of plant or vegetable origin and/or plant or vegetable ingredients of synthetic origin, but have properties, in particular structure and/or texture and/or other properties, corresponding or comparable to those of seafood.
- plant-based seafood product in particular “structured and/or textured plant-based seafood product”, as used according to the present invention refers to a product which is not derived from seafood.
- plant-based seafood product particularly the term “structured and/or textured plant-based seafood product” may also be termed as “seafood analogue product”, in particular “structured and/or textured seafood analogue product”, according to the present invention.
- plant or vegetable ingredients of synthetic origin as used according to the present invention preferably refers to ingredients being chemically synthesized, typically in a laboratory, microbially synthesized, i.e. synthesized by microorganisms, or recombinantly synthesized, i.e. by means of biotechnology and/or gene engineering.
- the plant-based product according to the present invention is free of animal derived ingredients, i.e. free of ingredients of animal origin.
- the term “texture” as used according to the present invention refers to the physical sensations in the mouth caused by food or drink, as distinct from taste. It is a fundamental sensory attribute which, along with taste and smell, determines the overall flavor of a food item.
- the term “texture” as used according to the present invention may also be termed as “mouthfeel”.
- the term “solid lipid” as used according to the present invention refers to a lipid being in solid form at room temperature, i.e. at a temperature of 18 °C to 30 °C, in particular 20 °C to 25 °C, and under atmospheric pressure, i.e. under the pressure within the atmosphere of Earth, in particular under a pressure of 101,325 Pa (standard atmosphere).
- liquid lipid refers to a lipid being in liquid form at room temperature, i.e. at a temperature of 18 °C to 30 °C, in particular 20 °C to 25 °C, and under atmospheric pressure, i.e. under the pressure within the atmosphere of Earth, in particular under a pressure of 101,325 Pa (standard atmosphere).
- hydrocolloid component refers to a dietary polysaccharide, in particular derived from plants and/or sea algaes, that forms a hydrocolloid together with water.
- the hydrocolloid has a dispersed phase (dispersed hydrocolloid component particles and dietary polysaccharide particles, respectively) and a continuous phase (water).
- the dispersed hydrocolloid component particles and dietary polysaccharide particles, respectively may have a diameter, in particular an average diameter, of 1 nm to 1 pm.
- the hydrocolloid component may exhibit gel forming properties and/or thickening properties and/or stabilizing properties in the presence of water.
- the hydrocolloid component as used according to the present invention is a water-soluble dietary polysaccharide, in particular being capable of increasing viscosity and/or pseudoplasticity of water or an aqueous media, in particular aqueous solution.
- a water-soluble dietary polysaccharide in particular being capable of increasing viscosity and/or pseudoplasticity of water or an aqueous media, in particular aqueous solution.
- all ingredients of the plant-based seafood product are of plant origin, i.e. are vegetable or herbal ingredients.
- the at least one fiber component enhances the texture of the plant-based seafood product.
- the at least one fiber component plays a vital role in forming a continuous fibrous structure together with the at least one protein and/or at least one protein concentrate and/or at least one protein isolate.
- the at least one solid lipid also functions as a texture builder by crystallization and soothes dry mouthfeel.
- both, the at least one solid lipid and the at least one liquid lipid function as an oily ingredient of the plant-based seafood product.
- the plant-based seafood product further comprises at least one protein masker.
- the at least one protein masker is at least one vegetable protein masker.
- the at least one protein masker is selected from the group consisting of maltodextrin such as maize maltodextrin and/or potato maltodextrin, ethyl alcohol, seaweed powder, medium chain triglycerides, and mixtures of at least two of the afore-said protein maskers.
- MCTs medium-chain triglycerides
- the medium chain triglycerides are/is coconut fatty acid and/or palm kernel oil.
- seaweed powder is preferably obtained from the algae Ascophyllum nodosum.

Seafood consumption of people has increased rapidly the past 20 years and it is estimated to grow by 30% within the next 10 years. At the same time fish farms threaten to collapse, intoxication of oceans will continue to increase and overfishing will continue to threaten marine ecosystems to go extinct. In addition, entry of antibiotics, mercury and microplastics in seafood will increase more than ever before.
Therefore, there exists an unmet need for food-based solutions that can be realized in large scales without harming the planet.

Preferably, the plant-based product according to the present invention is free of animal derived ingredients, i.e. free of ingredients of animal origin.
The term “texture” as used according to the present invention refers to the physical sensations in the mouth caused by food or drink, as distinct from taste. It is a fundamental sensory attribute which, along with taste and smell, determines the overall flavor of a food item. The term “texture” as used according to the present invention may also be termed as “mouthfeel”.
The term “solid lipid” as used according to the present invention refers to a lipid being in solid form at room temperature, i.e. at a temperature of 18 °C to 30 °C, in particular 20 °C to 25 °C, and under atmospheric pressure, i.e. under the pressure within the atmosphere of Earth, in particular under a pressure of 101,325 Pa (standard atmosphere). The term “liquid lipid” as used according to the present invention refers to a lipid being in liquid form at room temperature, i.e. at a temperature of 18 °C to 30 °C, in particular 20 °C to 25 °C, and under atmospheric pressure, i.e. under the pressure within the atmosphere of Earth, in particular under a pressure of 101,325 Pa (standard atmosphere).
The term “hydrocolloid component” as used according to the present invention refers to a dietary polysaccharide, in particular derived from plants and/or sea algaes, that forms a hydrocolloid together with water. Preferably, the hydrocolloid has a dispersed phase (dispersed hydrocolloid component particles and dietary polysaccharide particles, respectively) and a continuous phase (water). The dispersed hydrocolloid component particles and dietary polysaccharide particles, respectively may have a diameter, in particular an average diameter, of 1 nm to 1 pm. Advantageously, the hydrocolloid component may exhibit gel forming properties and/or thickening properties and/or stabilizing properties in the presence of water.

The at least one protein masker advantageously allows to hide the taste from the at least one protein, in particular from green pea protein, on a molecular level. In other words, the molecules of the at least one protein, which give a sensation of taste, are masked by the at least one protein masker, so that the at least one protein does not give a specific sensation of taste anymore.
This allows the plant-based seafood product to be given any desired flavor, in particular with an advantageous flavor release control, without the at least one protein's inherent taste still being recognizable.
In a further embodiment of the invention, the at least one protein masker has a proportion of 0.01 % by weight to 0.1 % by weight, in particular 0.02 % by weight to 0.08 % by weight, preferably 0.04 % by weight to 0.06 % by weight, based on the total weight of the plant-based seafood product.

According to a second aspect, the present invention relates to a method for preparing a plant- based seafood product, in particular a plant-based seafood product according to the first aspect of the invention. The method comprises the steps of a) providing a mixture comprising or consisting of
- at least one protein and/or at least one protein concentrate and/or at least one protein isolate,
- at least one fiber component,
- at least one solid lipid and/or at least one liquid lipid,
- at least one hydrocolloid component and
- water and b) shaping, preferably extruding, the mixture, in particular to obtain the plant-based seafood product.
Step a) may be carried out by using the at least one protein and the at least one fiber component in a mass ratio of 70 : 30, in particular 65 : 35, preferably 64 : 36.
In particular, step a) may be carried out by using a mixture or combination of soy protein and pea protein as the at least one protein and pea fiber as the at least one fiber component. Preferably, the soy protein, pea protein and pea fiber may be used in a mass ratio of 50 : 20 : 30, in particular 45 : 20 : 35, preferably 44 : 20 : 36.
Further, step a) may be carried out by further using at least one protein masker and/or at least one enzyme.
The at least one protein masker can be efficiently added in low proportions, especially in the proportions mentioned in the previous description, when applied before an extrusion of the plant-based seafood product. In particular, adding the at least one protein masker before an extrusion makes it easier to add the at least one protein masker to the plant-based seafood product and to control the dosage of the at least one protein masker.
The at least one enzyme, especially in the proportions mentioned in the previous description, has the advantage of being deactivated during an extrusion, especially during extrusion at a temperature of 100 °C to 150 °C, in particular 110 °C to 135 °C. Thus, a labelling of the at least one enzyme with respect to the final product is not necessary.
Further, step a) may be carried out by first providing a mixture, in particular dry, i.e. water-free, mixture, comprising or consisting of the at least one protein and/or at least one protein concentrate and/or at least one protein isolate, the at least one fiber component and the at least one hydrocolloid component, then adding the at least one solid lipid and/or the at least one liquid lipid, in particular in a molten form, to the mixture and finally adding the water, in particular in combination with the at least one enzyme, wherein the at least one enzyme is preferably diluted in the water.
Further, step a) may be carried out by using a mixture or combination of soy protein, pea protein and wheat protein as the at least one protein and pea fiber as the at least one fiber component. Preferably, the soy protein, pea protein, wheat protein and pea fiber may be used in a mass ratio of 50 : 10 : 10 : 30., in particular 45 : 10 : 10 : 35, preferably 44 : 10 : 10 : 35.
Further, step a) may be carried out by additionally using at least one hydrocolloid component. Alternatively or in combination, at least one hydrocolloid component may be added to the mixture before step b), in particular between step a) and step b). Further, step a) may be carried out for 0.5 h to 12 h, in particular 0.5 h to 6 h, preferably 0.5 h to 2 h.
Further, step a) may be carried out at room temperature, i.e. at a temperature of 18 °C to 30 °C, in particular 20 °C to 25 °C.
Preferably, step b), is carried out by using an extruder, in particular screw extruder, preferably twin screw extruder. In particular, the mixture obtained in step a) may be fed into the extruder via three feeders, preferably with an individually modulated speed. The extruder may be operated with an average screw speed of 500 rpm to 3000 rpm, in particular 500 rpm to 2500 rpm, preferably 500 rpm to 2000 rpm.
Further, step b) may be carried out, in particular by operating a barrel of the extruder, at a temperature of 100 °C to 150 °C, in particular 110 °C to 135 °C.
Further, step b) may be carried out by applying a shear or shear stress of 0.01 Pa to 1 Pa, in particular 0.01 Pa to 0.7 Pa, preferably 0.01 Pa to 0.5 Pa, to the end of the barrel of the extruder.
Further, step b) may be carried out by operating a die of the extruder at a temperature of 15 °C to 30 °C, in particular 20 °C to 28 °C, preferably 20 °C to 25 °C. Typically, the die is positioned at the end of the extruder.
Further, step b) may be carried out under a pressure, in particular overpressure, preferably applied to the barrel of the extruder, of 2 bar to 20 bar, in particular 5 bar to 20 bar, preferably 5 bar to 15 bar.
Preferably, step b), is carried out by means of high moisture extrusion or is carried out as high moisture extrusion. High moisture extrusion advantageously involves plasticizing of ingredients of the mixture, in particular protein molecules contained in the mixture, by applying heat and shear to the mixture in an extruder barrel, in particular heated extruder barrel, resulting in a plasticized melt, followed by forcing the plasticized melt through a cooling die positioned at the end of the extruder. With respect to useful heat and shear for applying to the mixture, reference is made to the temperatures and shear/shear forces disclosed in the previous paragraphs. Forcing the melt through the cooling die results in molecular alignment of molecules, in particular peptide and protein molecules, and preferably affords a fibrous anisotropic structure. Further, high moisture levels advantageously facilitate the extrusion process. As the plasticized ingredients, in particular protein(s), cool in the die, they become less flowable, and thus higher moisture levels assist with forcing the plasticized ingredients, in particular protein(s), of the mixture through the die.
The term “high moisture extrusion” according to the present invention refers to a barrel moisture content, i.e. to a moisture content of the above-mentioned barrel of the extruder, of > 40 % (w/w), in particular > 40 % (w/w) to 75 % (w/w), preferably 45 % (w/w) to 70 % (w/w), more preferably 45 % (w/w) to 60 % (w/w), in particular 45 % (w/w) to 55 %(w/w).
Further, step b), may be carried out by means of 3D-printing or may be carried out as 3D- printing. 3D-printing may, for example, involve loading a syringe with the plant-based seafood product as the printing material, which is then deposited through a nozzle layer by layer. Afterwards the plant-based seafood can be shaped, preferably after cooling. Further process treatment can be performed to improve the appearance of the plant-based seafood product by nutrition like surface treatment and/or coating.
Further, 3D-printing advantageously facilitates production of the plant-based seafood product customized in shape, color, texture, flavor, nutrition, and the like.
The term “3D-printing” as used according to the present invention refers to a process of making a physical object from a three-dimensional digital model, typically by depositing a multitude of layers of a material in succession.
Further, the method may comprise a further step c) cooling the shaped mixture obtained in step b), in particular to a temperature of 50 °C to 70 °C.
Further, the method may comprise a further step d) introducing the cooled mixture obtained in a step c) into a shredder and/or tumbler.
Further, additives, in particular selected from the group consisting of flavors, colorants, nutrients, especially vitamins and omega-3 fatty acids, and mixtures of at least two of the afore said additives, may be added, in particular before, during or after carrying out step d).
Further, the method may comprise a further step of packaging the plant-based seafood product.
