Definitions

  • the present invention relates to a process for preparing a whole grain cereal based extract.
  • the present invention relates to the preparation of a beverage comprising a beverage ingredient comprising the whole grain cereal based extract, which whole grain cereal extract maintain the nutritional value of the whole grain cereal and which makes it possible to provide the desired organoleptic properties of a beverage.
  • Extracts of cereals such as malt extract have been used as an ingredient in beverages, such as in cocoa malted beverages.
  • Malt extract an example of a cereal extract, was produced based upon the classic process used by breweries for making beer. In this process cereals such as barley or wheat are harvested and dried so that they can be stored until required for use.
  • the traditional malting process involves steeping the grain in water, germinating the grain for a period of days and stabilising the grain by carefully drying it to a low moisture content, typically around 5 % moisture.
  • enzymes for converting the starchy endosperm to soluble components are produced.
  • Enzymes such as a- amylaase, b-amylase, b-glucanase, proteases, arabinoxylanases are synthesised in the germinating grain. During malting these enzymes also modify the structure of the cell wall allowing easier and more complete extraction of the soluble fraction of the cereal during later steps in the process.
  • the malted whole grain cereal is typically ground by milling to a heterogeneous powder where it is mixed with water in a ratio of 3-10 (or sometimes even more) parts water to 1 part grain.
  • the initial temperature of the water may be around 40°C to 50°C to allow hydrolysis by proteases and cell-wall hydrolysing enzymes. Once this hydrolysis is sufficiently complete the temperature is raised to between 60°C and 70°C to allow hydrolysis of the starch by the a- and [3-amylases. Once the hydrolysis is complete the temperature of the slurry is increased to around 80°C to inactivate the enzymes.
  • the slurry is passed through a separating device such as a lauter tun, decanter or plate and frame filter.
  • the liquid portion is separated from the insoluble/partially soluble material by a process of filtration and leaching. Leaching involves washing the insoluble grain until all of the easily soluble material has been removed.
  • the liquid portion is stabilised by drying to a powder or evaporating to a paste with typical dry-matter content above 78 % (w/w).
  • the powder or paste obtained may be used as an ingredient in the beverage.
  • the residual insoluble material (spent grain) is typically sold as animal feed or disposed in land fill.
  • US 5,135,765 describes a process for producing a protein-rich product and/or a fibrous product which includes the steps of pressing brewer's spent grain in a wet state, and sieving water from the pressed brewer's spent grain in order to separate it into a protein-containing fraction and a fibrous fraction.
  • US 5,135,765 describes that fine grinding of the fibrous material should be prevented because it may lead to difficulties in the subsequent separation of the protein fraction from the fibrous fraction.
  • US 5,135,765 describes that the fibrous fraction obtained is used as feed or as a combustible fuel.
  • US 4,282,319 describes a process for the preparation of hydrolyzed products from whole grain, and such derived products.
  • US 4,282,319 describes the use of a proteolytic enzyme to transform water insoluble proteins into water-soluble products, and further to treat the starch contents with an amylase to form water- soluble starch products.
  • the product is further treated by removing the bran fraction and removing water to obtain a dry, semimoist, or liquid but concentrated derived product.
  • the product is to be added as a sweetening agent in food products such as bread, drinks, and cereal products, whereby the bran obtained can be used in bread as fibre additive.
  • US 4,282,319 does not describe a fibre comprising beverage ingredient that maintains the nutritional value of the whole grain cereal and which has improved suspension properties.
  • a portion of the cereal is not used in the beverage, but rather sold as animal feed.
  • This unused portion comprises a range of value added nutritional components such as fibres, proteins, polypeptides or amino acids, vitamins and minerals.
  • a further drawback of the traditional cereal extract is that it is especially unsuitable for cereals that generate a large portion of insoluble material after hydrolysis, such as barley and wheat.
  • the present invention provides that the nutritional value of the whole grain cereal is maintained or close to being maintained, where the suspension properties of the beverage ingredient are improved and/or which makes it possible to provide a beverage with the desired organoleptic properties.
  • a process for preparing a whole grain cereal based extract comprises the steps of:
  • the whole grain cereal and cereal spent grain is present in the ranges 50 to 60 wt. % whole grain cereal and 40 to 50 wt. % cereal spent grain.
  • the cereal based fraction comprising particles having a particle size below 100 pm, preferably below 50 pm, more preferably 30 pm.
  • the process according to the invention is furthermore a simpler process. It makes use of a side stream or waste material that are generally lower in price then green barley. Nevertheless, the final product is better nutritionally due to higher fiber content and higher protein.
  • the final beverage product which can be produced with the concentrate obtained by the process according to the invention still gets a good texture and sensory properties without grittiness and taste is comparable to 100 wt. % green barley concentrate.
  • the invention relates to a beverage ingredient comprising a concentrate obtained with a process according to the invention.
  • Figure 1 shows comparative profiling of beverage made using 100% green barley extract compared to beverage made using 50-50 (wt%) modified malt extract.
  • Figure 2 shows a schematic representation of a process of brewing on the left hand side creating spent grain and an embodiment of the process according to the invention on the right hand side of the drawing using the spent grain in the preparation of a modified whole grain cereal extract.
  • the process according to the invention for preparing a whole grain cereal based extract comprises the steps of:
  • the process according to the present invention may be as shown in the flowchart in figure 2.
  • the process illustrated begins with a whole grain cereal which may be allowed to malt before it is subjected to grinding.

  • cereal spent grain is an insoluble fraction of whole grain obtained after enzymatic hydrolysis or mashing.
  • the insoluble part of cereal spent grain is in the present context selected from cereal fibers, cereal bran, and cereal spent grain or a combination thereof.
  • the ground (malted) whole grain cereal may then be mixed with water and optionally enzymes to modify the whole grain cereal.
  • enzymes When the whole grain cereal has been sufficiently modified the enzymes are inactivated and the insoluble fraction of the whole grain cereal may be separated from the soluble fraction of the whole grain cereal.
  • the soluble fraction (or a fraction hereof) and the cereal based fraction (or a fraction hereof) are derived from different whole grain cereals.

  • insoluble fibres include celluloses, hemicelluloses, resistant starch type 1 and lignins.
  • Further benefits of insoluble fibres include promotion of the bowel function through stimulation of the peristalsis, which causes the muscles of the colon to work more, become stronger and function better. There is also evidence that consumption of insoluble fibres may be linked to a reduced risk of gut cancer.
  • Dietary fibres are the edible parts of plants that are not broken down by digestion enzymes. Dietary fibres are fermented in the human large intestine by the microflora. There are two types of fibres: soluble fibres and insoluble fibres. Both soluble and insoluble dietary fibres can promote a number of positive physiological effects, including a good transit through the intestinal tract which helps to prevent constipation, or a feeling of fullness. Health authorities recommend a consumption of between 20 and 35 g per day of fibres, depending on the weight, gender, age and energy intake.
  • the soluble fraction comprises the soluble fibres and the other soluble parts of the whole grain, e.g. proteins, vitamins, minerals, sugars, etc.
  • soluble fibres may also include dietary fibres that undergo complete or partial fermentation in the large intestine.

  • Soluble fibres from other sources include pectins, acacia gum, gums, alginate, agar, polydextrose, inulins and galacto-oligosaccharides for instance.
  • Some soluble fibres are called prebiotics, because they are a source of energy for the probiotics present in the large intestine. Further benefits of soluble fibres include blood sugar control, which is important in diabetes prevention, control of cholesterol, or risk reduction of cardiovascular disease.

  • Example 1 Comparative profiling of beverage made using 100% green barley extract compared to beverage made using 50-50 (wt%) modified malt extract
  • Table 1 shows a comparison of filtration, leaching rates and yield between 100% green barley-based malt extract process and modified malt extract process.
  • the leaching process in the current context is carried out after filtration process whereby water is passed through the spent grain to further extract the soluble matter trapped in the spent grain to maximize the yield of the overall process.
  • Yield in the present context is defined as the amount of dry matter extracted per 100 g dry matter of the initial material.
  • Table 2 shows a comparison of nutritional profile of 100% green barley-based malt extract and modified malt extract at 80% total solids. Protein and fiber are significantly higher in modified malt extract compared to 100% green barley malt extract with concurrent decline in available carbohydrates.
  • Figure 1 shows comparative profiling of beverage made using 100% green barley extract compared to beverage made using 50-50 (wt%) modified malt extract.
  • Example 2 Enzymatic hydrolysis of wet spent grain to improve nutritional properties of extract
  • Wet spent grain obtained as insoluble matter from the malted barley filtration process is combined with malted barley grist in 1: 1 fraction and subjected to enzymatic hydrolysis process. This processing is to further solubilize the insoluble present in the wet spent grain to obtain filtrate which undergo evaporation step to increase total solids content.
  • the goal of further solubilizing the wet spent grain is to modulate the nutritional profile of the extract called as modified malt extract.
  • This modified malt extract can have higher protein and dietary fiber content.
  • Example 3 Cacao beverage with modified whole grain and bran maltextract
  • the beverage has a caloric value below 255 kcal per serving and is intended to become consumed as a major part of the meal (e.g. breakfast).
