The present invention relates to a minced meat analogue, to a method of preparing such a minced meat analogue for consumption and to a process of producing such a meat analogue. Examples of minced meat analogues according to the present invention include vegetarian ground meat as well as vegetarian ground meat formed into patties (e.g. vegetarian hamburgers) or balls (e.g. vegetarian meat balls).
A burger (or hamburger) is a cooked patty of minced (or ground) meat, usually beef, that is typically placed inside a sliced bread roll or bun. The patty may be fried or grilled. Hamburgers are often served with cheese, lettuce, tomato, onion, pickles, bacon, or chili; condiments such as ketchup, mayonnaise, mustard, relish, or “special sauce”; and are frequently placed on sesame seed buns.
Since the term “burger” usually implies beef, for clarity “burger” may be prefixed with the type of meat or meat substitute used, as in beef burger, turkey burger, chicken burger, fish burger or veggie burger.
A veggie burger (or vegetarian burger) is a burger patty that does not contain meat.
These burgers may be made from ingredients like beans, especially soybeans and tofu, nuts, grains, seeds, algae or fungi such as mushrooms or mycoprotein.
The inventors have developed a minced meat analogue that can be cooked in the same way as ordinary minced meat to produce a cooked minced meat analogue that in terms of eating quality and appearance is very similar to meat-based reference products. The minced meat analogue of the present invention is easy to manufacture and can be stored in frozen form until it is prepared for consumption.
A first aspect of the invention relates to minced meat analogue comprising the following components:
The minced meat analogue of the present invention comprises TVP pieces and a binder emulsion that contains water, oil and fat particles. The binder emulsion can act as a lubricant and a glue that allows for the preparation of a coherent dough that can be pumped and shaped into a patty or a ball and does not fall apart during storage, handling and preparation. In addition, the binder emulsion has a major impact on the eating quality of the cooked minced meat analogue as it affects important quality attributes such as succulence, bite, oily mouthfeel and in-mouth flavour release.
Unlike known the minced meat analogues, the minced meat analogue of the present invention contains liquid oil and solid fat as separate components. In the preparation of meat analogues it is common practice to thoroughly blend liquid oil with molten solid fat before combining it with other food ingredients at a temperature above the melting point of the fat blend, so that upon cooling of the product mixture the solid fat can form a crystalline matrix that prevents oil exudation. This phenomenon is also used to avoid oil separation in margarines and shortenings.
The inventors have unexpectedly discovered that solid fat particles and liquid oil can be applied in the binder emulsion of the present minced meat analogue in the amounts indicated above, without causing significant oil exudation. In addition, it was found that the presence of both liquid oil and solid fat in the binding emulsion enables the preparation of the minced meat analogue at ambient or below ambient temperatures as both the fat particles and the liquid oil can easily be dispersed throughout the product mass during mixing. In contrast thereto, a blend of solid fat and liquid oil cannot easily be dispersed as such a blend is a semi-solid mass at ambient temperature. In order to disperse such a semi-solid mass, high shear conditions need to be applied that have an adverse effect on the structure of the minced meat analogue. An important advantage associated with the preparation of the minced meat analogue at near ambient temperature resides in the fact that oxidation of the unsaturated fatty acids in the liquid oil is effectively minimised.
A second aspect of the invention relates to a method of preparing the aforementioned minced meat analogue for consumption, said method comprising frying or grilling said minced meat analogue.
A third aspect of the invention relates to a process of preparing a minced meat analogue, said process comprising:
The words ‘comprising’ and ‘containing’ as used herein should not be interpreted restrictively as meaning ‘consisting of’. In other words, besides the features listed after these words, non-listed features may be present.
Unless specified otherwise, numerical ranges expressed in the format ‘from x to y’ or ‘x-y’ are understood to include x and y. When for a specific feature multiple preferred ranges are described in the format ‘from x to y’ or ‘x-y’, it is understood that all ranges combining the different endpoints are also contemplated. For the purpose of the invention ambient temperature is defined as a temperature of about 20° C.
Unless indicated otherwise, weight percentages (wt. %) are based on the total weight of the composition. Also, unless indicated otherwise, weight percentages as based on wet weight.
The term “water content” as used herein, unless indicated otherwise, relates to the total water content.
The term “minced meat analogue” as used herein refers to a vegetarian product that has an appearance and structure similar to that of minced meat. More particularly, like minced meat, the minced meat analogue of the present invention is largely (≥50 wt. %) composed of small pieces of elastic material that are wetted on the outside by an aqueous liquid. The term “minced meat analogue” also encompasses products shaped from such minced meat analogue, such as patties and balls.
The term “textured or texturized vegetable protein (TVP)” as used herein refers to a food ingredient made from edible protein sources and characterised by having structural integrity and identifiable texture such that each unit will withstand hydration in cooking and other procedures used in preparing the food for consumption. TVP is typically produced by extrusion.
The terms “oil” and “fat” as used herein refer to a glyceride component that contains at least 80 wt. % of glycerides selected from triglycerides, diglycerides and combinations thereof.
The term “liquid oil” as used herein refers to an oil that contains no solid at 20° C. (N20=0%). The solid fat content at 20° C. can be determined using ISO method ISO 8292-2:2008.
The term “solid fat” as used herein refers to a fat that contains at least 20% solid fat at 20° C. (N20≥20%).
The term “non-denatured” as used herein in relation to proteins refers to proteins that still have the secondary structure which is present in their native state.
The term “dry matter” as used herein refers to the matter that remains after water and other volatile components have been removed by evaporation using a forced-air oven (2 hours at 103° C., or longer if not all moisture has been removed).
The liquid oil and the solid fat particles are present in the minced meat analogue as separate components. A fraction of the solid fat particles may be captured as distinguishable fat particles in droplets of liquid oil, thereby reducing the liquidity of these oil droplets.
Besides the hydrated TVP pieces and the binder emulsion the minced meat analogue may contain other ingredients in the form of particulate material having a particle weight of at least 1 mg. Pieces of vegetable or spices are an example of such a particulate material.
The minced meat analogue of the present invention is preferably uncooked, allowing local preparation of the cooked minced meat analogue using conventional cooking techniques such as grilling and frying. Here “uncooked” means that the complete minced meat analogue, i.e. the minced meat analogue as whole, has not been heated to temperatures in excess of 60° C. Ingredients of the minced meat analogue, such as the TVP pieces, however, may have been heated to temperatures in excess of 60° C. during the production thereof.
In another advantageous embodiment, the minced meat analogue is frozen. More preferably the minced meat analogue is a frozen uncooked minced meat analogue. Most preferably, the minced meat analogue is frozen uncooked minced meat analogue shaped in the form of a patty or a ball.
