Abstract

A method of producing a seafood butter includes freezing pieces of seafood such as mussels, drying the pieces, grinding or blending the dried pieces to provide a powder, and mixing the powder into a butter carrier. The pieces are freeze-dried. The protein is dried to a moisture content of less than 0.0155% moisture w/w. The protein may be mussels. The butter has a long shelf life, not limited by the presence of seafood. It has a structure and consistency suitable for cooking as it "silts" on a piece of fish or meat, leaving a tasty dressing on top and oils melt to assist cooking.

Brief Description of the Drawings
The invention will be more clearly understood from the following description of some embodiments thereof, given by way of example only with reference to the accompanying drawings in which :-
Fig. 1 is a flow diagram illustrating a manufacturing method of the invention. Description of the Embodiments
Referring to Fig. 1 a protein butter, referred to herein as a "seafood butter" is produced in a method 1 having the following steps.
2. Fresh mussels are washed in a high pressure salt water jet.
3. Batches of washed mussels are pressure-cooked to ensure thorough cooking with shell opening. The typical batch size is 100 kg in shell. 4, The cooked mussels (still in shells) are blast chilled to less than 4°C for less than
90 minutes.
5 The shells are removed by shaking on a vibrating support table designed to remove the meats from the shells, the shells being eventually discarded to a shell bin and the meats moving to a meats bin. The meats can also be removed from the shells by hand.
6 The mussels are blast frozen at less than or equal to -18°C for less than 60 minutes This provides individual mussel pieces, without shells. The mussel pieces are subjected to a food-safe gas, such as nitrogen, to freeze each piece individually and rapidly.
Steps 3 to 6 are performed in a time period of less than five hours, to ensure that the mussels retain their freshness and nutritional value.
There is then a freeze-drying stage, in step 7: the mussel pieces are freeze dried to 0% to 0.5% w/w moisture content, at temperatures of between +40°C and -40°C, for a period of 20 hours to 24 hours. The moisture content after drying may be up to 1%, but is preferably below 0.5% w/w, and most preferably at or below 0.155% w/w.
The mussels are then ground down to a particulate size of 50μηι to ΙΟΟμιη. This powder is a very pure form of protein. This is achieved without addition of anti-spoilage agents, emulsifiers, anticoagulation agents, gelling gums, or anti-moisture agents. Also, there is a very low classified microbiological count, due to the lack of moisture in the resultant protein.
The total time for steps 7 and 8 is less than 24 hours because it allows the correct time, temperature and evaporation of moisture per kilo per hour per cubic metre in order to maximise yield of powder protein product.
Separately, dairy butter (in this case Irish dairy butter) is microwave tempered to about 30°C in step 20. Also, dry ingredients such as paprika and seaweed (marine algae) are filtered to a size of about 20μιη to ΙΟΟμηι in step 30, and are mixed by an agitator in step 31. These dry ingredients are air-dried in a conventional manner for supply of such ingredients in dry form. The butter (25°C to 35°C) and the powdered mussel protein from step 8 and the dry ingredients from step 31 are mixed by way of tempered agitation and tumbling before pumped extrusion. C02 is added to keep the mixture cool so that it does not separate.
The mixture is then allowed settle (41) for about 2 hours at 10°C. After this, the mixture is extruded (42), moulded (43), cut (44), and then instantly frozen in step 45 with parameters of 18° C within 5 minutes A major benefit of the process is that the end product butter has a very long shelf life, at least ninety days. This is because the moisture has been extracted from the seafood protein, providing very few sites for bacterial growth. At the same time the butter product has the benefit of providing a distinctive and concentrated seafood "Umami" taste. The manner of incorporation of the mussel protein is such that the fat molecules of the butter tend to adhere to the mussel protein. This provides a "silting" effect of seafood protein, butter fat and seaweed on food such as fish as it is cooked. In this case the butter oil will tend to run off to assist with cooking. The "silt" which remains on the fish is like a dressing with the desired taste of the mussel flavour along with that of the seaweed and any other additives.
Also, the product is relatively smooth, with a texture and consistency similar to that of the carrier butter, within which the dry ingredients such as seaweed can also be clearly tasted. Hence, the product can have any of a range of uses including as a spread or for cooking or for inclusion in sauces.
The following is a table of the nutritional values of a product having 88% w/w salted butter, 1 1% w/w shellfish protein (mussels), 1% Dillisk seaweed, and trace paprika. Nutrition Information

The invention is not limited to the embodiments described but may be varied in construction and detail. For example, the mussel protein may be dried by a step other than freeze drying, such as: spray dried,
microwaved,
radiated,
convection heated,
baked,
roasted.
For aspects such as ease of manufacturing, taste, consistency, susceptibility to drying during manufacturing, and compatibility with the carrier butter it is preferred that the protein source is predominantly or even exclusively mussels. However, it is envisaged that protein other than mussels or in addition to mussels may be used, for example: prawns, prawn shells, oysters, razorfish, lobster, lobster shells, crawfish, crayfish, crawfish shells, crayfish shells, abalone, periwinkles, sea snails, limpets, sea urchins, cockles, crabmeat, crab shell, clams, scallops, and/or flesh suitable for consumption such as: poultry, game, game poultry, wild fowl, beef, equine, equine game, reptile, and/or mixtures of any of the foregoing. Where it is shellfish, any shellfish may be used, fitting the general definition of being exoskeleton-bearing aquatic invertebrates. It is preferred that the protein be of a type having an initial moisture content of at least 60%, and hence shellfish are most suited. Also, it is envisaged that butter carriers other than dairy butter may be used, such as margarine or oil-based spreads.
