Description

The local flavor of coffee diet usable is assigned, strengthened or aromatics modifier
Technical field
The present invention relates to the coffee drink for making coffee extract contact to be heated and obtaining uniqueness with overheated steam The coffee flavor of food is assigned, strengthened or aromatics modifier and coffee flavor imparting, enhancing or the change by the coffee diet usable The imparting for the coffee flavor adjusted with micro addition in food or Enhancement Method.
Background technology
Coffee is to be liked the most popular hobby beverage drunk by people in the world, even so far with tea text The China and other various countries at center are turned to, with economical deposition, American-European fast food restaurant, coffeehouse culture permeate rapidly, its demand Sharply increase.
In Japan, wish easily taste the product of this consumer demand of coffee whenever and wherever possible as response, Japan obtains the container-packed coffee beverage, the coffee beverage of refrigeration-type, the coffee of contained in polyester bottles of the canned coffee of development alone etc. Numerous coffee processed goods such as coffee beverage or widely available instant coffee in general family are consumed by people.The opposing party Face, in recent years, in addition to coffee speciality store, coffee shop, coffee-house etc., due to the sales counter supply in convenience store coffee etc. it is emerging Rise, the coffee of the high-quality of " now grind, now infuse " can be easily bought with low price at any time, in the shape that can daily enjoy Condition.Therefore, in order to circulate and keep quality and the canned coffee of heat tracing sterilization, refrigeration coffee are in and are forced arduous competition Present situation, " now drying, now grind, now infusing " demand of material of the effect of sense with assigning increasingly increases.
The either coffee of coffee speciality store to be supplied in the way of " now dry, now grind, now infuse ", or canned coffee, speed Dissolved coffee etc., is all by being bakeed to coffee bean and coffee extract obtained from carrying out water extraction with water~hot water to it Thing, it is essentially identical in this.Industrially, the shape of dried powder is also concentrated or is made sometimes to coffee-extract State, but they are hereinafter referred to as coffee extract.In coffee extract according to circumstances and add sugar, milk and other Raw material etc. and be used as various coffee processed goods.The composition being known as in coffee extract is highly unstable, therefore when extracting Good taste and fragrance, the balance of so-called local flavor via manufacture, circulation, preserve and be more easily damaged.In this regard, propose with The scheme (patent document 1-3) that various methods are strengthened the fragrance of coffee, filled up etc..But, such scheme is not using Stable coffee extract, at this point, do not solve the quality deterioration of fragrance and taste fundamentally, thus need into The improvement of one step.In addition, the manufacture method of the coffee extract as the quality deterioration for inhibiting fragrance and taste, although exist The scheme that the low temperature extract solution of coffee and steam distillation extract solution are mixed, but still also room for improvement, and to look for novelty Scheme.
The fragrant and sweet fragrance of the characteristic of coffee, mainly by the sugar in roast coffee beans and amino acid due to heated The Maillard reaction of generation and bring into play, in addition, it is known that each in the coffee bean such as chlorogenic acid, caffeic acid, quininic acid Composition is planted also intricately to participate.The Maillard reaction of the fragrance of coffee after generation baking is oxidation reaction, on the other hand, For composition holds labile coffee, oxidation is formidable enemy, particularly the higher beans of baking degree, and moisture is due to baking Become few, the ratio of the caffeol in beans is uprised, therefore in the presence of the oxidative degradation after easily bakeing and easy catch fire Industrially along with danger the problem of.
But, after the Seattle system such as Startbuck coffee enters Japan, in Japan, hobby has used baking degree higher The tendency that depth bakees the coffee beverage of beans is further strengthened, as a result, in the coffee of the type of addition milk, for body Reveal the coffee sense do not covered by milk, also increase the use of depth baking beans.In addition, the situation with bakeing beans using either shallow Compare, in the case where being bakeed using depth, can consumingly obtain full (Body) sense, agreeable to the taste sense, satisfaction, therefore, also Often interacting depth bakees beans in either shallow bakees beans, but as already described, deposits oxidative degradation after baking, catches fire The problem of, and expect improving environment.
On the other hand, as new heating means, the utilization of overheated steam receives much concern.Originally, overheated steam Using starting from for the 1980's, but only bread, aquatic products meat etc. two, three.But, after generation nineteen ninety, open Electromagnetic induction heating mode, resistance heating manner, electric heating mode of heating etc. are sent out, as a result it utilizes and developed rapidly.Utilize overheat Vapor and the heating that carries out is characterized in rapid and the thermal efficiency is very high, be the less heating of oxygen.Overheat is utilized as using , there is the method shown in patent document 4-7 in vapor and the related scheme of the baking of the coffee bean of heating that carries out, but all Method in, be difficult to using the heating of overheated steam due to hypoxia critically important for the baking of coffee bean Maillard reaction, also, because the thermal efficiency is higher, therefore it is very fast to be carbonized, and exists and is difficult to balancedly give play to depth from beans Bakee the shortcoming of the baking fragrance of beans.In addition, there is the manufacture method of following volatile ingredient in patent document 8:In inertia In closed container under gas atmosphere, the overheated steam prepared using the water of deoxygenated state is set to be connect with above-mentioned tasty material After touch, the steam after the contact is reclaimed, but this method is with height for baked coffee bean using common overheated steam The method that efficiency reclaims the volatile ingredient in baked coffee bean, haves the shortcomings that obtained volatile ingredient is still unstable.
Therefore, seek it is a kind of without these problem of the prior art, assign depth bakee beans fragrance and taste it is new Technology.

Embodiment
In the present invention, the water extract of roast coffee beans refers to put forward roast coffee beans with water such as warm water, hot water Extract obtained from taking (hereinafter referred to as " coffee extract ").In the case of oneself manufacture coffee extract, first, choosing It is set for the green coffee of the raw material of the roast coffee beans to be used in coffee extract.Green coffee is not particularly limited, Arabica kind, Liberia's kind, Robusta's kind etc., no matter its species, the place of production, can also use Brazil, brother's rival The green coffee in any place of production such as Asia, Indonesia.In addition, green coffee, can be used alone a kind of raw beans, can also make With mixed more than two kinds of life beans.Coffee bean after can above-mentioned raw beans be bakeed by coffee baker etc. is used as original Material, but it is not limited to this.
Next, coffee baker etc. can be used to pass through the baking of conventional method progress green coffee.For example, can be by Green coffee is put into the inside of rotating cylinder, one side Stirring while with gas burner etc. from below to the rotating cylinder Heated, thus bakeed.The baking degree of the coffee bean, as long as the baking for the degree generally drunk, can With in any scope, for example, it is 14.5-30 that can bakee to L values.L values are the indexs for the baking degree for representing coffee, are to use Value obtained from colour difference meter is measured to the lightness of the crushed material of baked coffee bean.L values are 0 expression black, and L values are 100 tables Show white.Therefore, the baking of coffee bean is deeper, numerical value more low value, more shallow then more high level.As reference, for generally drinking Bakee the L values degree substantially as shown below of beans.Italian type bakees (Italian Roast):16-19, French Roast (French Roast):19-21, deep city bakee (Fullcity Roast):21-23, city bakee (City Roast): 23-25, dense baking (High Roast):25-27, moderate bakee (Medium Roast):27-29.As making in the present invention The baking degree of coffee bean, can use the coffee bean in the range of 14.5-30, preferably 16-20 or so.In addition, may be used also Not damage in the range of the local flavor of the imparting of the local flavor of coffee flavor diet product of the present invention, enhancing or aromatics modifier, one is used Beans of the part L values more than 30 or a part of L values are less than 14.5 beans.
Coffee bean after baking can be crushed, and conventionally use intermittent continuous extraction element, dribbling Extraction element, the multi-function device with mixer, other extraction elements, are extracted with water such as warm water, hot water, are filtered, by This obtains coffee extract, but is not limited to this.In addition, on coffee extract, will be by various methods, for example, decompression Concentration, freeze concentration, reverse osmosis membrane are concentrated, extracted using concentrated coffee obtained from the various methods such as the concentration of synthetic adsorbent Thing, further these coffee extracts are referred to herein as by the materials of various method powdereds such as spray drying, freeze-dryings " coffee extract ".
Further, being circulated as commercially available product has various coffee extracts, also, can also specify the species of beans, bakee Degree etc. desired coffee extract is bought as commercially available product, these coffee extract can also be used.In addition, commercially available Instant coffee also substantially according to the product prepared with these coffee extract identical manufacture methods, can be in the present invention It is middle to be used as coffee extract.
The soluble solid of the coffee extract used in the present invention is 10 mass %-100 mass %, according to coffee The character of extract can be divided into two kinds.A kind of model of soluble solid for being derived from coffee in 10 mass %-90 mass % Interior liquid coffee is enclosed, another soluble solid of coffee that is derived from is in the range of 90 mass %-100 mass % Coffee in powder form.Any type can be used, but using moisture is less and solid content higher liquid coffee or powder Coffee, preferably use coffee in powder form in the case of, heating treatment time for generating preferable fragrance is shorter, obtained firing The crushing of thing is easier to, and can obtain good fragrance, the product of the present invention of fragrance of the roast coffee beans with generation.Pass through The use of the soluble solid from coffee is preferably 25 mass %-100 mass %, more preferably 50 mass %-100 matter The coffee extract in the range of %, more preferably 70 mass %-100 mass % is measured, roast coffee beans can be obtained The strong preferable product of the present invention of fragrance, fragrance.
In addition, can be added in the coffee extract used in the present invention according to expectation, be mixed with sodium acid carbonate etc. Other food materials such as pH regulators, sodium ascorbate, antioxidant, spices, sugar, amino acid, food additives, its opportunity exist Before and after being heated using overheated steam.
Next, on the overheated steam used in the present invention, as long as the vapor of the temperature higher than 100 DEG C is Can.Specifically, vapor is further heated and reached higher than 100 DEG C at ambient pressure obtained from being heated to water The vapor of temperature is exactly overheated steam.Overheated steam is filled generally according to the difference of the mode of heating of vapor Put and classified.That is, exist using heater, lamp directly, the electric heating heater that heats indirectly, by sensing heating, The high-frequency heating such as dielectric heating and directly or indirectly heater.
For commercially available home-use cooking device, IH culinary art cooking devices are the forms of the indirectly heat by sensing heating, Micro-wave oven is direct-fired form by sensing heating.On the other hand, the steam shown up prominently in recent years and popularized rapidly Baking oven, the home-use cooking device for the utilization overheated steam for being referred to as water oven (registration mark, Sharp Corp's manufacture) are to use The cooking device of the form that heater is heated by direct, electric heating, can easily carry out cooking using the food of overheated steam Adjust.Specifically, Healsio (registration mark, Sharp Corp's manufacture) can be enumerated as.These home-use cooking devices are empty in semi-hermetic It is interior to be heated using overheated steam therefore very efficient.
On the other hand, the also commercially available overheated steam generating means for having a business.Specifically, Genesis can be enumerated as (wild village skilled worker Co., Ltd. manufacture), DHF Super-Hi (registration mark, First Takasunami Industries Co., Ltd.), SV Roaster HOT MAX (registration mark, Co., Ltd. Zhongxi makes manufactured), QFB-5980C-3R (registration mark, this straight work Industry Co., Ltd.), super baking oven (clear this ironworker Co., Ltd.) etc., but be not limited to this.
In the case where making overheated steam be contacted with coffee extract, contacted under substantially atmospheric pressure.I.e., neither especially Pressurizeed and also do not carry out especially contacting and being heated with overheated steam with depressurizing.
Next, the temperature of overheated steam during on being contacted with coffee extract is, it is necessary to the coffee of actual treatment Amount, heat time and the heating-up temperature of extract these three combination come determine obtain as purpose coffee fragrance and taste Condition.The temperature (that is, heating-up temperature) of overheated steam when being contacted with coffee extract can be enumerated as higher than 100 DEG C and Temperature in less than 1000 DEG C of scope, more preferably preferably 120-500 DEG C, 170-300 DEG C of temperature.In addition, during heating Between can generally be enumerated as -5 hours 0.1 minute, preferably -3 hours 0.1 minute, more preferably -2 hours or so 0.2 minute when Between.
It is containing about 60- in coffee extract in the case where being heated using overheated steam to coffee extract In the case of the liquid coffee of 80% or so water, if the increase of dry volume occurs after heating, but while end is heated Shrink, the firing thing as the lamellar of brown~persimmon or the plastic partial desiccation solid-state of tool.Grinder can also be used Crushed that powder is made and uses or adds water again and dissolved and used with liquid.
On the other hand, in the case where being heated using overheated steam to coffee in powder form, after heating, occurs volume anxious Acute increased phenomenon, i.e. expanded as the bulking (puffing) when occurring to bakee equivalent to coffee bean, expanded lasting Certain time after-contraction, obtains the firing thing of persimmon~black.It can be crushed and powdered or dissolving with grinder Reclaim in a liquid.
The degree of firing can be adjusted by time for being contacted with overheated steam and its temperature, as determining to be used to obtain The index of the heating condition of the fragrance of preferable baked coffee bean and the firing thing of taste must be played, can use and be expressed from the next Numerical value, i.e. extract baking degree.
Extract baking degree=(sample before sample weight-heating after sample weight-heating before heating it is aqueous Amount)/(sample weight before heating) × 100
Wherein, the water content of the sample before heating is set to the value obtained by following formula.
Sample weight × solid content (%) ÷ before sample weight-heating before water content=heating of sample before heating 100
When being fired using overheated steam to coffee extract, the water evaporation that contains first in coffee extract and send out Raw concentration, at the time point of water evaporating completely, the numerical value for representing above-mentioned extract baking degree is 0.If being fired from that point on, Then soluble solid than water gasifies due to various reactions, reduced, therefore the numerical value becomes big.Firing is more further entered The row numerical value becomes bigger.Excessively carry out, be carbonized if firing, damage preferable fragrance and taste, therefore, extract dries Roasting degree is preferably less than 30.
By various researchs as a result, numerical value by being set to extract baking degree in the range of -30 to 30, more excellent Elect the numerical value in the range of -10 to 25 as, overheated steam processing coffee extract, i.e. the coffee diet of the present invention can be obtained The coffee flavor of product is assigned, strengthened or aromatics modifier.Although fragrance, the taste characteristic of the firing thing in the range of being somebody's turn to do are different, Baking local flavor is respectively provided with, is added by the firing thing that will be obtained in coffee processed goods etc., the local flavor of the firing thing can be assigned Feature.In addition, herein, the fragrant and mellow fragrance and taste that local flavor refers to the existing mill that baked coffee bean has is bakeed, it is particularly deep Complicated fragrance, taste that the baking beans that degree is bakeed have, but also include by baking the coffee of generation in its local flavor Sootiness (smoke) sense for preferably bakee (roast) sense, generating in the case where bakeing progress etc..
Furthermore it is possible to the degree fired with other index expressions.Surveyed by gel permeation chromatography (hereinafter referred to as " GPC ") During the molecular weight distribution for the water soluble ingredient being set in the coffee extract for raw material, molecular weight about to 1,000,000 larger model In enclosing, several peak values are confirmed.On the other hand, it is small peak in raw material coffee extract in coffee extract after firing Significantly there is larger peak value, table for the macromolecule region near 200,000-100 ten thousand in the molecular weight for being worth or being nearly no detectable It is bright intentionally to add the composition that molecular weight is more than 200,000.
In addition, by various researchs as a result, can confirm, for the preferable perfume (or spice) with baked coffee bean of the present invention The overheated steam processing coffee extract of gas and taste, is measured with GPC to its aqueous solution, and to Differential refractometer (RI) The aggregate-value of response quautity when measuring, weight average molecular weight is converted as the ratio shared by more than 200,000 part using pulullan polysaccharide Example is more than 15% of the water soluble ingredient entirety in the above-mentioned aqueous solution.
Generally, if bakeing too strong during roast coffee beans, bitter principle increase, becomes unsuitable for drink while carbonization With.On the other hand, it is of the invention bakeed by extract obtained from coffee extract, be to be handled by above-mentioned overheated steam Obtained from fire thing, generation has the fragrance of strong degree very much while the bitter taste of the original high-quality of coffee is generated.On Strong degree, the present inventor speculate, with overheated steam processing coffee extract in emerging weight average molecular weight be More than 200000 composition is relevant.Herein, strong degree refers to assign the satiety of coffee, thick and heavy sense, agreeable to the taste sense, satisfaction etc The rich property of local flavor.
Why overheated steam processing coffee extract on so obtaining can have extracts as the coffee of raw material The baking local flavor of the baked coffee bean lost in thing, although still can not scientifically be proved, but it is assumed that in coffee extracting In thing containing it is many to roast coffee beans when generate fragrance component, taste composition change unreacted precursor component, for example, The compositions such as sugar, amino acid, chlorogenic acid, caffeic acid, quininic acid, trigonelline, caffeine, grease, if passing through overheated steam pair They carry out the heating with bakeing same degree, i.e. extract and bakeed, then these compositions are completed and produced in baking The same complicated chemical change of chemical change, so that the preferable fragrance and taste that generate baked coffee bean (bakee fragrant, baking Local flavor).
In addition, according to the consideration, by using overheated steam as heater meanses, in the coffee extract headed by grease Composition is difficult to aoxidize, therefore almost without undesirable tart flavour, miscellaneous taste, on the other hand, the object of heating is not coffee bean But coffee extract, therefore, it is difficult to produce carbonization and dominant generate the composition made contributions to fragrance and taste.Separately Outside, overheated steam processing coffee extract is the solidfied materials such as powder, compared with the extract of liquid, the guarantor of its fragrance and taste Deposit that stability is very good, this point is also excellent characteristic.
The present invention has following characteristics:The coffee obtained by overheated steam to the baked coffee bean after crushing is extracted Thing is heated and can generated, and the baking lost is fragrant, bakee local flavor, and resulting coffee extract has the coffee of high-quality The bitter taste of coffee, it is also more stable after preservation, offending fragrance and taste will not be generated.Therefore, even if being added to coffee Also the balance of coffee flavor will not be damaged in diet product, by it is a small amount of~add in large quantities, assign baking while intensity can be changed Fragrant, baking local flavor, assigns strong degree, alcoholic degree sense, baking sense, sootiness sense of coffee etc. with further changing intensity.Further, The firing thing of obtained persimmon~black is crushed and solution in a liquid is dissolved, sediment is few and with coffee Preferable color, therefore can be also used for the coloring of coffee diet product.
The coffee extract of product of the present invention, fragrance and complicated taste with baked coffee bean (bakee fragrant, baking wind Taste) and high-quality the bitter taste of coffee, color, it is and also very stable after being saved, be used as the coffee of unique coffee diet usable Local flavor is assigned, enhancing or aromatics modifier are very useful.In addition, there is the characteristics of will not generating offending fragrance and taste, therefore i.e. Increase addition is not also damaged the balance of coffee flavor of coffee diet product, therefore, it is possible to be widely used in coffee beverage, Milk beverage, coffee jelly, coffee cookies, coffee chocolate, coffee pudding, coffee Bava containing coffee reveal this, coffee cake etc. It in all diet products with coffee flavor, in addition, can add in various diet products, various products can be held Change places imparting in conventional coffee extract not obtainable baking local flavor while, assign the strong degree of coffee, satiety, Bakee sense, sootiness sense etc..
Then, enumerate embodiment and more specific description is carried out to the present invention, but the present invention is not limited in these implementations Example.
