Description

A kind of preparation method of inexpensive milk flavour of candy milk base material
Technical field
The present invention relates to a kind of preparation method of milk base-material, and in particular to a kind of system of inexpensive milk flavour of candy milk base material Preparation Method.
Background technology
Milk-taste essence, also referred to as frankincense flavouring agent.It can be used for the milk fragrance for strengthening beverage, candy, bakery product etc., reach Improve the purpose of flavor and mouthfeel.It is a kind of to possess milk fragrance, the essence of widespread adoption in the food industry.Milk Savory essence accounting in food ingredient is relatively small, but contribute on flavour of food products it is huge, it have supplement, stably, it is fixed, change Therefore the effect of kind fragrance, these influences of effect to the selling market of product are greatly simultaneously increasingly taken seriously.Dairy products institute The fragrance ingredient kind contained has no big difference, simply forms different perfume (or spice) because of the difference in the quantity and ratio of flavor component Taste.Mainly have three kinds of the production technology of frankincense essence:Method, blending method, fermentation method and the blending that enzyme process and blending are combined The method being combined.
Enzyme process, it is to produce milk-taste essence with main raw material(s)s such as dilute cream, milk, passes through lipase disaggregating milk fat fat.From And obtain strengthening nearly 200 times of frankincense raw material.This mode is one of ideal selection of the savory gas flavouring of milk.With this side The milk-taste essence fragrance that preparation is adjusted in formula is pure, stronger than milder.The maximum benefit of this mode is exactly, because enzyme is special One property can have to substrate and its single-minded recognition capability, it is desirable to which the product for generating diverse fragrant flavour can be by changing reaction condition To be prepared, the product fragrance of different-style becomes therefrom, product aroma of pure, soft, strong, overcomes traditional chemical conjunction Into milk-taste essence mouthfeel it is dull, single the characteristics of.
Enzyme process prepares natural milk-taste essence, it is possible to reduce the caused material that can cause environmental pollution in production process, and Raw material availability is high, and Product Safety is also higher.
In terms of production cost, the milk base-material cost developed in the past using chemical synthesis is relatively low, but its maximum Shortcoming is exactly that fragrance remaining time is not lasting.Grown with the product fragrance remaining time of biological enzyme development, but cost consumption is but on the contrary with it.
The content of the invention
A kind of inexpensive milk flavour of candy milk is provided it is an object of the invention to overcome the shortcomings of the prior art part The preparation method of base-material.
To achieve the above object, the technical scheme taken of the present invention is:A kind of preparation of inexpensive milk flavour of candy milk base material Method, comprise the steps of:
(1) substrate, is weighed, water, auxiliary substrate, vanillic aldehyde and ethylmaltol is added, sterilizing, is cooled to 35~45 DEG C;
(2) lipase lipase A 12, are added, after digesting 3~24h under the conditions of 35~55 DEG C, destroy the enzyme treatment, obtain enzyme Solve liquid A;
(3) protease MSD, is added into enzymolysis liquid A, after digesting 3~24h under the conditions of 35~55 DEG C, destroy the enzyme treatment, is obtained Enzymolysis liquid B;
(4), to enzymolysis liquid B centrifugal treatings, upper oil phase is taken, produces the milk flavour of candy milk base material;
Wherein, the substrate is the mixture of cream and palm oil.
Palm oil is a vegetable oil, also referred to as saturation grease.Containing 50% saturated fat, can partly substitute other Vegetable oil and animal oil.The price of palm oil is floated with the migration of the general grease price in the world.Human body disappears to palm oil Change and absorptivity is more than 97%.Palm oil does not contain cholesterol in itself, is a kind of edible plant for complying fully with health needs Thing oil.
The purpose of the present invention be on the premise of flavor is not changed optimize technique to reduce cost.Natural milk-taste perfume base spices Usually developed only with butter or cream.The production cost of cream is higher, and therefore, the present invention adds suitable in cream The palm oil of amount.Palm oil not only has abundant nutritive value, and does not contain cholesterol in itself, economical, uses it to Instead of partially creamed milk, make cream and palm oil turn into mixed substrates to optimize screening, its caused savory base of milk is existed Cost is reduced on the premise of not changing flavor.
Ethylmaltol has following function as a kind of additive:1. strengthen overall flavor characteristics, improvement food Product flavor, build the flavor of round and smooth mediation;2. possessing sweetened characteristic, increase and improve sweet taste, reach and reduce sugar dosage Effect;3. desalinating the astringent taste of food, suppress, using rear taste caused by sweetener, to make food that there is the flavor of balance;4. strengthen The butterfat sense of dairy products, produce the sliding mouthfeel of perfume of similar high-fat foods;5. the overall tart flavour for reducing food improves overall flavor, Suppress sour pungent taste caused by some food additives, make flavour of food products softer.
The auxiliary substrate can be selected from casein, whey powder and skimmed milk power.These three cosubstrates are containing a certain amount of Lactose and protein.By the reaction of lactose and protein in hydrolytic process, make the fragrance of hydrolysate more mellow and full rich Richness, there is stereovision.

The present embodiment investigates the palm oil content influence fragrant to production, to the embodiment 4 of embodiment 1, embodiment 5 and comparative example 1, Milk base-material obtained by 2 carries out acid value determination and sensory evaluation, test result are shown in Fig. 1.
It will be seen from figure 1 that acid value is on a declining curve, sensory evaluation is all relatively higher.Palm oil accounts for the weight of substrate Highest scoring when percentage is 30%, it is the most comfortable that now obtained milk base-material, which is used for mouthfeel in biscuit technique, sweet taste Also highlight, and milk fragrance is also very pure natural.Cream is only added to be prepared, although giving off a strong fragrance, cost It is higher.With the increase of palm oil mass ratio, milk fragrance is somewhat thin out, but milk fragrance and the comprehensive coordination of milk flavour of candy gradually increase By force.Palm oil contributes milk fragrance few compared with cream after digesting in itself, increases palm oil content, have passed through enzyme digestion reaction, add milk The harmony of flavour of candy and milk fragrance.Consider, most suitable palm oil content ratio is 30%.
Embodiment 21
The present embodiment investigates the species of auxiliary substrate to the fragrant influence of production, to the milk obtained by embodiment 1, embodiment 6~9 Base-material carries out acid value determination and sensory evaluation, test result are shown in Fig. 2.
Figure it is seen that score is most when three kinds of auxiliary substrate selection whey powder, casoid flour and skimmed milk power collocation It is high.Auxiliary substrate selection whey powder in the past, whey powder, sweet fragrance deficiency, with burnt odor taste are added merely.Whey powder is not added with, is only added Add casoid flour and skimmed milk power, then almost there is no milk fragrance, only strong sweet taste, biscuit, mouthfeel and taste are fabricated to it Road does not all have the taste of milk fragrance, only raw material.Add skimmed milk power sample, then be that flavor is not enough coordinated, lasting soon, band There is the taste of a little burnt odor but have shy taste.It can thus be concluded that other two kinds of auxiliary substrates in addition to whey powder, itself flavor are exactly Milk and sweet taste, three kinds of material mixings are enriched as milk base material milk fragrance made from the scheme of auxiliary substrate, exist a little bad Flavor, but biscuit technique is fragrant and sweet and the harmony of milk is relatively more preferable, and also fragrance remaining time is relatively long.Considering cost, Most suitable auxiliary substrate kind is three kinds of whey powder, casoid flour and skimmed milk power material collocation uses.
Embodiment 22
The weight that the present embodiment investigates whey powder, casoid flour and skimmed milk power compares the fragrant influence of production, to the He of embodiment 1 Milk base-material obtained by embodiment 10~13 carries out acid value determination and sensory evaluation, test result are as shown in Figure 3.
From figure 3, it can be seen that the weight ratio of the whey powder, casoid flour and skimmed milk power is:Whey powder:Casein Powder:Skimmed milk power=2:3:Sensory evaluation scores highest when 1, and the content proportion of skimmed milk power is relatively small, illustrates to reduce degreasing The addition of milk powder can allow fragrance purer.Consider, the addition of three is optimal when being above-mentioned ratio.
Embodiment 23
The present embodiment investigates the addition of ethylmaltol to the fragrant influence of production, to embodiment 1,14,15 and comparative example 3,4 Obtained milk base-material carries out acid value determination and sensory evaluation, test result are as shown in Figure 4.
From fig. 4, it can be seen that ethylmaltol addition is 0.75% scoring highest of substrate weight percentage, this When obtained milk base material milk fragrance it is plump, sweet taste coordinate.When the addition of ethylmaltol is less than substrate weight percentage 0.75%, the aroma strength of milk base-material strengthens with the increase of the addition of ethylmaltol.And work as ethylmaltol Addition be more than substrate weight percentage 0.75% when, the fragrance flavor coordination of milk base-material can reduce, and work as ethyl Bad flavor occurs when being more than the 1% of substrate weight percentage in the addition of maltol.Find, do not add under comparison Ethylmaltol can not make milk base-material volatilize the unique perfume of itself.It thereby it is assumed that, appropriate addition ethyl wheat Bud phenol, the fragrance presentation for strengthening milk fragrance and sweet fragrance can be played;But excessive addition ethylmaltol then occurs instead Effect, the sweet taste of ethylmaltol can cover the milk fragrance that milk base-material gives out in itself, can form bad pungent flavor.It is comprehensive Close and consider to understand, most suitable ethylmaltol addition is the 0.75% of substrate weight percentage.
Embodiment 24
The present embodiment investigates lipase lipase A 12 addition to the fragrant influence of production, to embodiment 1, embodiment 16, Acid value determination is carried out with the milk base-material obtained by comparative example 5~7 and sensory evaluation, test result are as shown in Figure 5.
From fig. 5, it can be seen that when lipase lipase A 12 addition is the 0.2% of substrate weight percentage Score highest, and the milk base material milk aromatic flavour now prepared, sweet fragrance is abundant, in terms of the fragrance and flavour synthesis of biscuit technique It is very high.When the addition of lipase is less than the 0.15% of substrate weight percentage, with the increase of the addition of lipase, Enzymolysis also strengthens therewith, and the milk fragrance of milk base-material, milk flavour of candy are more abundant, and the degrees of coordination of each side fragrance also strengthens; When the addition of lipase is more than the 0.15% of substrate weight percentage, with the increase of the addition of lipase, milk The fragrance scoring of base-material has declined, and when the addition of lipase is more than the 0.2% of substrate weight percentage, occurs bad Smell.Reason is probably that can play a part of promotion in the case where addition is appropriate, but when adding excessive lipase, can It can be digested during enzyme digestion reaction and produce a large amount of flavor components, bad smell is mingled in milk fragrance, sweet taste, milk flavour of candy Together, cause flavor mixed and disorderly.Consider and understand, the addition of most suitable lipase is the 0.2% of substrate weight percentage.
Embodiment 25
The present embodiment is investigated in step (2), and the enzymolysis time of the lipase lipase A 12 is right to the fragrant influence of production Milk base-material obtained by embodiment 1, embodiment 17 and comparative example 17~19 carries out acid value determination and sensory evaluation, test knot Fruit is as shown in Figure 6.
From fig. 6, it can be seen that lipase lipase A 12 enzymolysis time is in 5~8h, acid value change is gentle, it is seen that Enzyme digestion reaction degree is similar, and enzymolysis time is 5h sensory evaluation scores highest, and the sweet fragrance of milk base-material is more prominent, biscuit Mouthfeel it is more excellent.When lipase lipase A 12 enzymolysis time is less than 8h, with the extension of enzymolysis time, milk base-material Flavor it is more strong, it is fragrant and sweet;When the enzymolysis time of lipase A 12 is more than 8h, with the growth of enzymolysis time, milk base-material Sense organ comment fragrant fraction to be gradually reduced, or even in enzymolysis time be 12h, resulting milk base-material, which occurs, substantially makes people displeased Fast peculiar smell.In summary, enzymolysis time is too short, and reaction is insufficient, and sample can be caused not discharge also with tempting fragrance Unrighted acid;And enzymolysis time is long, then bad flavor material can be caused also to increase, so as to have impact on overall milk fragrant breeze Taste.Consider production cost, most suitable lipase lipase A 12 enzymolysis time is 5h.
Embodiment 26
The present embodiment investigates protease MSD addition to the fragrant influence of production, to embodiment 1, embodiment 18 and comparative example Milk base-material obtained by 11~13 carries out acid value determination and sensory evaluation, test result are as shown in Figure 7.
From figure 7 it can be seen that the addition of protease is 0.04% highest scoring of substrate weight percentage.Work as egg When white enzyme MSD addition is less than the 0.04% of substrate weight percentage, with the increase of protease MSD addition, institute The fragrance of obtained enzymolysis product is more soft, honest strong.It is substrate weight percentage in protease MSD addition The milk taste of the milk base-material prepared under conditions of 0.04% is full, and milk flavour of candy enriches, and both harmony is also high.Work as egg When white enzyme MSD addition is more than the 0.04% of substrate weight percentage, the fragrance scoring of milk base-material is slightly reduced, smell Slightly dull, the shortcomings of moving swiftly and be impractical.When protease MSD addition is more than the 0.04% of substrate weight percentage When, there is peculiar smell in product.Reason is probably that protease MSD addition is excessive, enzyme saturation and substrate is insufficient, continue increase enzyme it is dense Degree influences less on enzymolysis speed, and can make excessive hydrolysis, hydrolysate is become sour, causes the generation of bad flavor.It is comprehensive Consider, most suitable protease MSD addition is the 0.04% of substrate weight percentage.
Embodiment 27
The present embodiment is investigated in step (3), the enzymolysis time of the protease MSD to the fragrant influence of production, to embodiment 1, Milk base-material obtained by embodiment 19 and comparative example 14~16 carries out acid value determination and sensory evaluation, test result such as Fig. 8 institutes Show.
From figure 8, it is seen that protease MSD enzymolysis time is 10h highest scoring.When enzymolysis time is less than 8h, The fragrance variation of milk base-material, plumpness strengthen with the increase of enzymolysis time.When enzymolysis time is 8~10h, although sour Valency has decline by a small margin, and especially when enzymolysis time is 10h, obtained milk base material milk fragrance is relatively more abundant, cake Dry technique is also relatively excellent, has milk flavour of candy.When enzymolysis time is more than 10h, the fragrance scoring of milk base-material also declines therewith. It can to sum up obtain, in suitable enzymolysis time, protease hydrolyzes the protein in cream, produces small-molecular peptides and polypeptide Taste compound so that the more soft nature of the taste of product;And excessive hydrolysis can then make product souring, become product mouthfeel Obtain bad flavor that is thin, or even producing thorn larynx.Consider, most suitable protease MSD enzymolysis times are 10h.
