The present invention relates to a savoury seasoning composition, a method of preparing such a composition and to uses of such a composition.
Savoury seasoning compositions, such as bouillon powders are popular ingredients in both commercial and consumer kitchens. Savoury seasoning compositions are usually combined with hot water and optionally further food ingredients, such as vegetables or a protein source, to prepare a ready-to-eat savoury product (e.g. a bouillon, a soup, a sauce or a gravy).
WO03000076 describes a granulated, herb bouillon powder which had the following composition: 47% milled salt 33% milled monosodium glutamate 12% olive oil 6.5% dehydrated powdered aromatics and spices 1.0% colouring green plant extract solution 0.5% dried herbs.
WO 2007/085609 describes a bouillon and/or seasoning tablet and/or cube, which comprises, in total % in weight, 0.5-10% oil, and/or 0-5% fat, binders, salt, between 1 and 5% of total water, as well as between 0.5 and 8% of cereal, vegetable and/or fruit fibers, as well as optionally sugar, spices, flavors, taste enhancers, dehydrated vegetables, herb leaves and/or plant extracts. The binders are taken from the group consisting of dextrose syrup, maltodextrin, citric acid, meat extract and processed flavors.
Consumers are, however, put off by powdery, savoury seasoning compositions that have an artificial appearance. Also, for ease of use free-flowing compositions are desirable rather than lumpy, agglomerated powders that lead to difficulties in weighing out such seasonings.
Known savoury seasoning compositions are used to impart a certain flavour aspect to a dish, for example a meaty or vegetable flavour aspect, but should not be too dominant otherwise the resultant dish is unappetizing. Traditional savoury seasoning compositions lack any food structuring properties.
There is therefore a need to prepare savoury seasoning compositions that have a pleasant taste and natural visual appearance. In addition, it is desirable that the savoury seasoning composition has food structuring properties, e.g. provides an improved mouthfeel.
The inventors of the present invention have developed a particulate, savoury composition that has a pleasant visual appearance, taste and texture.
The inventors have unexpectedly found that the visual appearance of a bouillon can be improved by including 1-30 wt. % of puffed maize endosperm particles. The present savoury composition is more appealing due its more natural, less clumpy appearance to the consumer than traditional bouillon powders.
It has been surprisingly found that by food products prepared using the savoury composition of the present invention have an improved mouth feel and savoury taste compared to reference products. Unexpectedly, the puffed maize endosperm particles enhance the pleasant umami characteristics of soup or bouillon made using the savoury composition, while suppressing the saltiness and acrid onion & garlic notes of the savoury composition.
Accordingly, there is provided a particulate, savoury seasoning composition comprising:
The present invention further pertains to a method of preparing such a particulate, savoury seasoning composition. Accordingly, there is provided a method for the preparation of a composition as defined herein, comprising the steps of:
a. providing the particles of puffed maize endosperm;
b. combining the particles of puffed endosperm with an edible salt selected from sodium chloride, potassium chloride and combinations thereof; savoury taste giving ingredients selected from glutamate, 5′-ribonucleotides, sucrose, glucose, fructose, lactic acid, citric acid and combinations thereof and up to 10 wt. %, by weight of the composition, of water;

The visual appearance of the savoury composition can be analysed using the CIE L*a*b* colour model as defined by the International Commission on Illumination (CIE) in 1976 (ISO 11664-4:2008; Colorimetry—Part 4: CIE 1976 L*a*b* Colour space). The three coordinates of CIE colour model represent the lightness of the colour (L*=0 yields black and L*=100 indicates diffuse white; specular white may be higher), its position between red/magenta and green (a*, negative values indicate green while positive values indicate magenta) and its position between yellow and blue (b*, negative values indicate blue and positive values indicate yellow).
The CIE L*a*b* colour model is perceptually uniform, i.e., a change of the same amount in a colour value produces a change of about the same visual importance. In other words, Euclidean distance in the colour space is proportional to human perception. Change in colour can be determined using Equation (1):
The magnitude of dE represents a change in colour. As used herein, “dE” means a dE for a savoury seasoning composition as defined herein, the dE being calculated by reference to a composition that corresponds to the savoury seasoning composition as defined herein without particles of puffed maize endosperm.
Preferably, the particulate, savoury seasoning composition as defined herein, has a dE of more than 0.5, more preferably a dE of more than 1.0. Preferably, the particulate, savoury seasoning composition as defined herein has a dE in the range of 1.0 to 2.0, more preferably a dE in the range of 2.0 to 4.0, even more preferably more in the range of 4.0 to 5.0, yet more preferably a dE of more than 5.0.
Maize is cultivated around the world. The fruits or maize cobs contain the seeds of the maize, known as maize kernels. Maize kernels have a typical shape and structure, which typically includes a germ, endosperm and pericarp. The endosperm tissue of maize is particularly rich in starches, typically amylase and amylopectin. In addition, it has a relatively high fibre content. The pericarp (hull) of maize kernels is relatively strong and water-impermeable
The particles of puffed maize endosperm can be suitably obtained by puffing of maize endosperm, followed by milling or other methods of size reduction. The term “puffing” as used herein also encompasses popping of maize endosperm. If for example popped popcorn is comminuted, the resulting mixture of particles may include germ, endosperm and pericarp, but most of the volume and weight will usually be constituted by the expanded endosperm.
Depending on the comminution method, it may be desirable to fractionate the ground material, in order to obtain a particulate material with a suitable size distribution. Such fractionation is conveniently carried out by sieving, which is a well-known technique.
The particle size distribution of the particles of puffed endosperm material used in the present invention can also conveniently be analysed by sieving. It is preferred that such analysis is carried out following the sieving method described in the Examples section below.
Puffing of maize endosperm requires a high starch content. Preferably, the maize endosperm has a starch content of at least 50 wt. %, more preferably of at least 60. wt. % and most preferably of at least 70 wt. %, by weight of dry matter.
A process of puffing can for example be done, by pre-cooking and drying the maize kernels, followed by a heating step (e.g. frying in oil). Alternatively, the maize kernels can for example be puffed by explosion/gun puffing, where the raw or pre-cooked maize kernels are placed in a sealed drum that is rotated and heated from the outside until a certain pressure is obtained, the lid is released and all maize kernels puff at the same time, and escape the drum via the lid, and are collected in a bag where water vapour can escape.
Maize kernels comprise a water impermeable hull, which keeps the water inside the seed during heating, are suitable for popping. Popping is an (almost) explosive form of puffing, in which heating of the maize kernels causes starch gelatinization and pressure build-up due to steam formation until the hull bursts and the maize kernels explosively expands to form a foamy structure.
The particles of puffed maize endosperm are preferably obtained from puffed popcorn, more preferably from popped popcorn. Certain maize cultivars have been specifically bred for their suitability to be popped, including for instance Zea mays var. everta. Therefore, the particles of puffed maize endosperm are most preferably sourced from Zea mays var. everta.

In a preferred embodiment, the composition comprises 1-20 wt. %, by weight of the composition, of oil, preferably 2-15 wt. %, more preferably 5-10 wt. %, of oil.
The terms ‘fat’ or ‘oil’ are used interchangeably, unless specified otherwise. The terms ‘fat’ and ‘oil’ as used herein refers to glycerides selected from triglycerides, diglycerides, monoglycerides, phosphoglycerides, free fatty acids and combinations thereof. Where applicable the prefix ‘liquid’ or ‘solid’ is added to indicate whether the fat or oil is liquid or solid at 20° C.”
The term “liquid oil” as used herein refers to fat that is liquid at 20° C.

The determine of savoury compositions was assessed using the CIE L*a*b model. This model allows directly comparison between samples and calculation of colour differences. The analysis was conducted using a Spectrometer model CM-5 (Konica Minolta). Spectral range is 360-740 nm; 10 nm steps. measured at 20° C.
From the measured L*a*b values the colour difference dE be calculated according to equation 1:
dE=√((d L2)+(d a2)+(d b2) (1)
where dL=L*2−L*1; da=a*2−a*1; db=b*2−b*1
where dE:
The samples are stored for 1 month under nitrogen atmosphere. The color analysis was done on both powder and solutions made up by dissolving the powder with 95° C. water (16-20 g/L). The dilution factor is accordingly adjusted to make sure the amount of taste giving ingredients is the same per L.
Compositions shown in Table 2 were prepared in two steps. 3 Kg of basic mix without fillers (extruded potato starch, wheat fibres and milled puffed maize powder) are weighted and mixed in Kennwood at speed 1 for 3 mins. The oil is added slowly and then adjust the speed to 2 and mix for another 5 mins. Parsley pieces are added and then mixed at speed 1 for 2 mins. 54 grams of different fillers were added to 447 grams of basic mix and then mixed in Kennwood at speed 4 for 1 minute.
