Definitions

• the present invention relates to a taste enhancer, to a method for making the taste enhancer and to food products improved by the taste enhancer.
• the taste of food products may be enhanced by adding taste enhancing powders based on vegetables, such as mushrooms and tomatoes. Many of these taste enhancing powders are made by spray drying vegetable parts and residues from processing which are normally discarded on a maltodextrin carrier. The spray dried powders add a bouillon or umami taste to the food products to which they are added.
• a disadvantage is that the food product to which the powder has been added now contains maltodextrin which needs to be included in the product label, as such or as flavouring. Maltodextrin also may have a negative influence on the product taste and leads to dilution of the vegetable material in the powder.
• WO 01/30179 describes flavouring onion and garlic powders prepared from onion or garlic powder, which is hydrolysed for 20 hours, then dried on a maltodextrin carrier and used to introduce or enhance onion and garlic notes in food products. Fermentation of the hydrolysate is required to obtain meaty flavours.
• the present invention relates to a vegetable powder comprising at least 90% w/w dry vegetable material, less than 0.01% w/w maltodextrin and a savoury or pan-fried smell or taste.
• the powder is typically coloured and not hygroscopic.
• the powder according to the invention may be used to improve a food product, in particular to improve its taste or flavour, for example by improving its flavour profile or texture experience or by masking off-notes.
• An improved food product according to the invention shows one or more of the following improvements in comparison to the food product to which no powder has been added: a more balanced flavour profile, less off-notes, a sweeter taste, more umami taste, more creaminess or more kokumi taste.
• the powder according to the invention gives food products a better flavour balance e.g. by suppressing sourness peaks in the food product.
• An advantage over spray-dried products is that the powder according to the invention has a more intense savoury taste than spray-dried products. Therefore, lower amounts of the powder according to the invention can be used to get a similar effect.
• the powder according to the invention allows for clean and clear labelling of the improved food product containing the powder, because the powder does not need a carrier, such as salt, maltodextrin or starch, for drying.
• Clean labelling refers to having no or only a few additives on the product label.
• Clear labelling refers to products with a label with ingredients which are clear to the general customer. Therefore, food products comprising the powder according to the invention may be promoted as products with a clean and clear label. This is in contrast to spray-dried products, which typically comprise a carrier or filler, such as maltodextrin, which need to be included in the product label of the end product.
• the powder according to the invention can be used to intensify many different tastes. Addition of the powder typically gives a food product a more balanced flavor profile, a savoury or more umami taste, frequently with an improvement on the creaminess.
• a mushroom powder according to the invention is used to enhance the creaminess of a mayonnaise, without adding a mushroom taste.
• the powder according to the invention is a dry powder which is stable, i.e. not hygroscopic.
• a more balanced taste or flavour profile refers to a taste or flavour profile in which all the taste or flavour components are on a level where they do not stand out (no taste or flavour peaks) compared to the total taste or flavour profile.
• a powder according to the invention gives a mayonnaise a more balanced profile by suppressing its sourness.
• Taste and flavour are preferably evaluated by a panel of trained panellists.
• the panel preferably comprises at least five, at least six, at least seven, at least eight, at least nine or at least ten trained panellists.
• the panel comprises from 5 to 20, 5 to 15 or 10 to 20 trained panellists.
• descriptive sensory analysis is used for taste and flavor evaluation.
• the Quantitative Descriptive Analysis (QDA®) technique is used, which is one of the main descriptive analysis techniques in sensory evaluation. Using the QDA® technique, a panel of 5 to 10 or 5 to 12 panelists will be sufficient for effective sensory evaluation.
• sweetness refers to the taste of sugar and may be assessed by a panel of trained panellist on the base flavour sweet.
• a panel is trained enough on sweet if each panellist at least nine out of ten times tastes the difference between any pair of (i) water, (ii) water with 0.3% w/v sugar and (iii) water of 0.5% w/v sugar.
• umami refers to the savoury taste and mouthfeel of monosodium glutamate (MSG), which may also be obtained with 5′ribonucleotides as GMP and IMP.
• MSG monosodium glutamate
• a product with more umami taste typically has more savoury taste.
• Umami taste may be assessed by a panel of trained panellist on the taste and mouthfeel of umami. A panel is trained enough on umami if each panellist at least nine out of ten times tastes the difference between any pair of (i) water, (ii) water with 0.03% w/v of MSG and (iii) water with 0.05% w/v MSG added.
• kokumi refers to the linger longer effect of a taste or flavour.
• a product with more kokumi taste typically has more richness and heartiness in taste.
• Kokumi taste may be assessed by a panel of trained panellist on the taste and mouthfeel of kokumi.
• a panel is trained enough on kokumi if each panellist at least nine out of ten times tastes the difference between any pair of (i) water and (ii) water with 0.01% w/v of Ajirex NH (Kohjin, Tokyo Japan) and (iii) water with 0.025% w/v of Ajirex NH added.
• creaminess refers to the taste of fat or cream and the oral sensation of a thick, smooth liquid or semi-liquid. Creaminess may be assessed by a panel of trained panellist.
• masking off-notes refers to masking unpleasant or undesirable flavour notes or peaks, in particular sour, fishy and earthy notes.
• the masking of off-notes may be assessed by a panel of trained panellist. A panel is trained enough on off-notes if each panellist at least nine out of ten times tastes the difference between (i) water and (ii) water with low dosages of base flavours.
• the term off-notes refers to taste components that are present or present in high amounts without adding to the total flavour profile.
• the powder is oven-dried at vacuum pressure and no carriers, in particular no maltodextrin, are added for drying.
• the powder comprises at least 90% w/w dry vegetable material, less than 0.01% w/w maltodextrin and a savoury or pan-fried smell or taste.
• the dry vegetable material in the powder constitutes at least 90% w/w, preferably at least 92% w/w, at least 94% w/w or at least 95% w/w, such as from 90% to 100% w/w or 95% to 100% w/w.
• the powder comprises no maltodextrin at all. In another embodiment, the powder comprises at least 90% w/w dry vegetable material, no maltodextrin and has a savoury and pan-fried smell and taste.
• the pan-fried taste is the effect of the preparation method of the powder and not the result of the production of reaction flavours from sugars and amino acids.
• the powder is typically coloured.

• Mushroom paste was obtained from Scelta Mushrooms BV (Venlo, The Netherlands, Mushroom Concentrate centrifuged—M 60). This mushroom paste had a dry matter of 58%. The paste was blended with 2% on dry matter of citric acid (citric acid androhydrous, Jungbunzlauer Austria AG, Vienna Austria). The mixture was evaporated in a rota vapor film evaporator with a product temperature of 62 degrees Celsius until a dry matter of 75% was reached. 200 gram paste was poured on a tray with a surface area of 143 cm 2 .
• the paste was dried in a preheated oven (Binder Oven type VD115 with a Vacuubrand pump PC 3004) at 105 degrees Celsius on a vacuum of 100 mbar. After one hour the vacuum was lowered to 10 mbar. After three hours at 10 mbar the cake reached a temperature of 92 degrees Celsius and the oven vacuum was turned off.
• the dried paste also referred to as cake, was removed from the oven and allowed to cool until room temperature. Next the cake was ground using a hammer mill (KitchenAid Artisan 5ksb555ebuo, KitchenAid, Gouda, the Netherlands) to pass a 1 mm-mesh sieve which resulted in the powder.
• the mushroom powder was solved at 0.3% w/w dosage in full fat Zaanse mayonnaise (Van Wijngaarden, Wormerveer, the Netherlands).
• a QDA® expert panel (seven members) compared the taste of the prepared product with the taste of full fat Zaanse mayonnaise (control).
• the mushroom powder gave an enhanced taste intensity, aftertaste, sweetness and creaminess of the mayonnaise.
• the mayonnaise had a more sweet, more kokumi and more umami taste with an improvement on the creaminess and a better flavour balance by suppressing the sourness.
• a cold-break quality tomato paste with a dry matter content of 65% w/w was incubated with 0.33% (w/w) of the Enzyme TAIL31 Viscosity reduction, 0.33% (w/w) of the Enzyme 26 Betaglucanase and 0.33% (w/w) of the Enzyme TAIL54 Xylanase/Betaglucanase (Tailorzyme, Stiborg, Denmark) at pH 5.2 for two hours at 50 degrees C. while being stirred.
• 200 g of paste was poured on a tray with a surface area of 143 cm 2 and dried in a preheated oven at 105 degrees C. with a vacuum of 100 mbar for 60 min. Then, the vacuum was reduced till 20 mbar and the product was dried till a product temperature of 94 degrees Cat 20 mbar, the dried paste was removed from the oven and allowed to cool to room temperature.
• the cake was ground into a powder.
• a cold-break quality tomato paste with a dry matter content of 65% w/w was incubated with 0.5% w/w of a 1:1 mixture of Cellulase A Amano 3 and Hemicellulase Amano 90 (Amano Enzyme Europe, Oxfordshire, United Kingdom) at pH 5.2 for two hours at 50 degrees C. while being stirred.
• 200 g of paste was poured on a tray with a surface area of 143 cm 2 and dried in a preheated oven at 105 degrees C. with a vacuum of 100 mbar for 60 min. Then, the vacuum was reduced till 20 mbar and the product was dried till a product temperature of 92 degrees C. at 20 mbar, the dried paste was removed from the oven and allowed to cool to room temperature.

• the onion powder gave the mayonnaise a fuller, sweeter and more umami and more kokumi taste with an improvement on the creaminess and a better flavour balance by suppressing the sourness.
• the onion powder also gave a clear onion flavour. Panel members appreciated the taste and it had a slight deep fried or pan fried onion taste with a long and sweet after taste. If the onion flavour is not desired, it may be blended in at a lower dosage, i.e. lower than 0.3% w/w. It will give the same effect without the onion taste.
• Example A The onion powder prepared in example 6 (sample A) was compared to a commercial spray-dried onion juice powder (sample B).
• the spray-dried powder was produced by spray-drying the juice of onions with about 50% carrier of maltodextrin. Both powders were dosed on 0.1% w/w in clean label instant beef bouillon.
• a QDA® expert panel (six members) evaluated the effect of the powders on clean label instant beef bouillon (Table 1).
• the onion powder according to the invention was found most pleasant, more balanced and more umami, stronger in salty taste, less bitter and more meaty than the clean label instant beef bouillon.
• Sample B was described as strong pungent onion taste and smell, slight enhancement of herbal notes, no difference on umami and saltiness perceived in comparison to the clean label instant beef bouillon.
• the powder according to the invention had a higher overall taste enhancement compared to commercial spray dried powder and was able to give a more balanced, more umami and more meaty taste without introducing an onion taste.
• Example 9 Mushroom Powder According to the Invention Compared to Alternatively Produced Products
• the mushroom powder according to the invention was found most pleasant, less sour, more balanced, pan-fried, creamy and fatty and has a higher taste enhancement.
• Sample (D) was described as sweeter, slightly sourer, creamier and a little starchy.
• Sample (B) was described as unpleasant, starchy, and strong in off note. The off note was described as mushroom or yeast extract.
• Sample (C) was described as having the least impact, making the Zaanse Fritessaus a little less sour, extra creamy and fatty but having a musty taste.
• the powder according to the invention was least sour, most balanced, creamiest, and highest taste enhancement of all tested powders although it was used in the lowest amount of all powders tested. This shows that less powder according to the invention is required to get a positive effect.
