Definitions

  • the present invention relates to a composition comprising plant fiber, low methylester soluble pectin and high methylester soluble pectin.
  • the invention also relates to this composition as a semi-finished product for use in the food industry, and here in particular for the production of a milk substitute drink or a protein-containing fruit drink and the use for the production of these drinks.
  • the invention relates to a milk substitute drink or a protein-containing fruit drink that has been produced using the composition according to the invention.
  • the invention also relates to a method for producing a milk substitute drink or a protein-containing fruit drink.
  • the milk substitute drink or the protein-containing fruit drink is preferably a vegan drink.
  • milk is an important protein-containing food and can look back on a long tradition that goes hand in hand with the introduction of dairy farming in the Neolithic and the lactose persistence acquired through mutation.
  • cow's milk for animal welfare, environmental protection and climate protection reasons or for ethical reasons.
  • health reasons that speak against consuming cow's milk.
  • milk components cannot be broken down sufficiently in the body (due to lactose intolerance or milk protein intolerance) or that other milk ingredients are not tolerated.
  • the Federal Institute for Risk Assessment (BfR) also sees cow's milk as one of the "most important allergy-triggering foods in childhood.
  • Milk substitutes or milk substitute products are colloquially referred to as foodstuffs that resemble milk or milk products in terms of taste or appearance and in terms of fat or protein content, without being made from it. They are usually purely vegetable foods. Soybeans with a protein content of approx. 35% by weight are particularly suitable as a protein-rich vegan food base.
  • the fat the soybean is rich in mono and polyunsaturated fatty acids and is cholesterol-free. Soy contains mostly polyunsaturated omega-6 fatty acids.
  • the soybean is also rich in so-called phytoestrogens - plant compounds with hormone-like effects, which are mainly associated with the lower incidence (frequency) of vascular diseases such as coronary heart disease in East Asian countries.
  • soy protein is therefore often used as an alternative to milk protein in the production of neutral and slightly acidified protein-containing drinks.
  • Soy protein isolates and soy protein concentrates are often poorly or not completely soluble and also exhibit poor storage stability.
  • the insoluble portion of soy protein (depending on the soy product used) can be stabilized by increasing the viscosity.
  • Gellan gum (E 418), guar gum (E 412), cellulose (E 460) or carboxymethyl cellulose (E 466) are currently used to stabilize vegan milk substitute drinks. These additives have low consumer acceptance as they are not considered to be of natural origin.
  • the vegetable protein must be protected against denaturation during the usual thermal treatment. Partial denaturation during production can lead to sedimentation of the proteins. This raw material-related sedimentation can be prevented by increasing the viscosity with one of the aforementioned stabilizers.
  • the object of the present invention is to improve the prior art or to offer an alternative to it.
  • the task at hand is achieved by a composition comprising plant fibre, low methylester soluble pectin and high methylester soluble pectin.
  • composition according to the invention offers the advantage that the plant proteins are protected from denaturing due to thermal treatment.
  • pectin and citrus fiber results in a synergy that both protects the proteins from denaturing during heating and builds up the necessary viscosity to keep the undissolved, dispersed components in suspension over the storage period.
  • composition according to the invention it is thus possible to improve the storage stability to such an extent that undissolved particles do not sediment and the vegetable proteins contained are also protected during the pasteurization process and precipitation of the same is effectively prevented.
  • composition according to the invention allows an optimal taste and aroma release.
  • compositions are obtained from plants and preferably from fruits and are therefore natural ingredients with well-known positive properties.
  • the basic components listed above are usually obtained from vegetable processing residues such as citrus or apple pomace. These are available in sufficient quantities and offer a sustainable and ecologically sensible source for the basic components present.
  • both the plant fiber and the pectin can be obtained from one and the same raw material source.
  • citrus fiber and citrus pectin with different degrees of esterification can be obtained from citrus pomace.
  • apple fiber and apple pectin with different degrees of esterification can be obtained from apple pomace.
  • the resulting fruit or milk substitute drinks meet all the usual requirements for such beverage products.
  • composition according to the invention it is possible to produce milk substitute beverages which, with regard to the rheological properties, produce an impression comparable to cow's milk and on the basis of which it is possible to provide various sensory neutral milk substitute products.
  • composition according to the invention comprising as basic components a plant fiber, a low methylester soluble pectin and a high methylester soluble pectin.
  • composition according to the invention thus contains a total of three pectin sources, of which two pectins are present separately from the plant fibers as low esterification and high esterification pectin and the plant fiber as the third pectin source, which also contains water-soluble pectin in addition to protopectins.
  • Protopectins are insoluble pectins and probably not pure homoglycans.
  • the polygalacturonic acid chains are connected to one another by complex bonds with divalent cations, via ferulic acid groups and borate complexes, and via glycosidic bonds with neutral sugar side chains, which can consist of arabinose, galactose, xylose, mannose and traces of fucose.
  • the plant fiber also contains water-soluble pectin, as explained above, it is also referred to as “plant fiber containing pectin” within the scope of the invention.
  • the composition according to the invention consists essentially of plant fibre, low methylester soluble pectin and high methylester soluble pectin.
  • “essentially” means that the composition contains at most 5% by weight, preferably at most 4% by weight, preferably at most 3% by weight, more preferably at most 1% by weight of other components.

  • the vegetable fiber of the composition is an activated pectin-containing fruit fiber or a partially activated, activatable pectin-containing fruit fiber.
  • an “activated pectin-containing fruit fiber” is a fruit fiber that has sufficient strength in a suspension so that no additional shearing forces are required in use in order to obtain the optimum rheological properties such as viscosity or texturing on the part of the user.
  • a “partially activated, activatable pectin-containing fibre” is understood to mean a fruit fiber which has a satisfactory strength in a suspension as a result of the partial activation in the production process. This activation can be described as partial insofar as it has not yet led to the theoretically possible final strength of the fibre. However, in order to obtain the optimal rheological properties such as viscosity or texturing, the user needs to activate it further by applying additional shearing forces. It is therefore a matter of partially activated fibers, which can, however, be further activated.
  • this plant fiber (regardless of its activation state) is selected from the group consisting of citrus fibre, apple fibre, sugar beet fibre, carrot fiber and pea fibre, the plant fiber preferably being a fruit fiber and particularly preferably a citrus fiber or an apple fibre.

This achieves thermal comminution, and a mechanical comminution step is therefore not necessary as part of the manufacturing process. This represents a decisive advantage over conventional fiber manufacturing processes, which in contrast require a shearing step (such as (high) pressure homogenization) to obtain a fiber with sufficient rheological properties.
