The present invention will be hereafter illustrated in a manner of specific embodiment.It should be understood that these embodiments are only illustrative, and The not intended to limit present invention.

The raw materials used oil of embodiment is purchased from Southseas Specialty Fats Industrial (Shanghai) Co., Ltd., and transesterification grease is using chemical ester Exchange method, can refer to Meng Zong (" tallow plastic fat dusting mechanism and inhibit research ", Wuxi: Southern Yangtze University, 2011, P67-68)。

Used other methods and material are that conventional method and material, material can be obtained by commercially available approach in embodiment ?.

Preparation example

Formula (data are weight percentage in table, with the total restatement of lotion) preparation embodiment 1-6 shown according to the form below 1 and right The grease composition of ratio 1-5.Specific processing technology includes: that concentrated whey protein powder, whole milk powder are dissolved in whole water In, 15min is stirred under the conditions of 50 DEG C of water-bath.White granulated sugar and locust bean gum are uniformly mixed, are added in above-mentioned emulsion, after continuation of insurance Temperature stirring 10min.Converted starch, citric acid, potassium sorbate, salt are uniformly mixed, are added in above-mentioned emulsion, is stirred 10min.Oily phase is added, Silverson cutter 7000rpm shears 1min, and then lotion crosses RVA under the conditions of 200/40bar Homogenizer, obtained lotion stir gelatinization 20min, pack, ice water cooling in boiling water bath.

Table 1

Note: content=concentrated whey protein powder × 80%+ milk powder × 20% × 20% of lactalbumin；Casein content= Milk powder × 20% × 80%.

5% aqueous solution of each concentrated whey protein powder is measured into its partial size in 50 DEG C of stirrings after ten minutes, or at 85 DEG C Its partial size is tested in stirring after ten minutes.Concentrated whey protein powder used is commercially available.

As a result as shown in the following table 2 and 3.

Table 2

Table 3

Test case 1

It takes a certain amount of sample to be put into piping bag, is extruded into strip and is placed on baking tray, be put into the oven of 180 DEG C of preheatings, bake 5min takes out conformality, emulsion stability and the mouthfeel of observation sauce.

It takes a certain amount of sample to be extruded into strip, is put into -18 DEG C of freezen protectives of refrigerator 3 weeks, take out sample and be put into 10 DEG C of constant temperature Case 20 hours, observe the water-oil separating situation of sample surfaces.

In conformality result, " 5 " point indicate that conformality is good, and slight deformation is not collapsed；" 4 " point indicate that conformality is good, Slight deformation is not collapsed；" 3 " point indicate slight deformation, there is collapsing；" 2 " point indicate Collapse Deformation than more serious；" 1 " divides table Show complete Collapse Deformation.

In emulsion stability result, " 5 " point indicate no oil leak；" 4 " point indicate that hand touching has minimal amount of oil；" 3 " point Indicate obvious oil droplet；" 2 " point indicate a large amount of oil droplet；" 1 " point indicates that oil leak is serious, basic water-oil separating.

In mouthfeel evaluation result, " 5 " point indicate smoother taste；" 4 " point indicate that mouthfeel is slightly coarse；" 3 " point indicate mouth Sense is obvious coarse；" 2 " point indicate that mouthfeel is obviously coarse；" 1 " point indicates coarse mouthfeel.

In freeze-thaw stability evaluation result, " 5 " point indicate that sauce body surface absolutely not oil or elutriation go out；" 4 " point indicate Sauce body surface has minimal amount of oil or elutriation to go out；" 3 " point indicate that sauce body surface has apparent oil or elutriation to go out；" 2 " point indicate sauce Body surface face has a large amount of oil or elutriation to go out；" 1 " point indicates that sauce body oil or elutriation go out than more serious, and sauce body structure is seriously destroyed.

As a result as shown in table 5 below.

Table 5

This test case has investigated the influence of lactalbumin and casein content to Ka Shida sauce.The results show that lactalbumin Emulsifying effectiveness is good, does not add emulsifier, and the emulsifying effectiveness of sample is also fine.The sample conformality added more than lactalbumin is good, bakes Sample is oil-proof afterwards.Casein emulsifying effectiveness is bad, easy Collapse Deformation after the sample more than casein is roasting, but the resistance to height of casein Temperature baking, mouthfeel remains unchanged fine and smooth smooth after baking.By the reasonably combined of lactalbumin and casein, high temperature resistant baking can be produced Fat or oil composition sample roasting and that change mouth is good.

Test case 2

The grease composition of formula shown according to the form below 6 (data are weight in table) preparation comparative example 6-9.Specifically Processing technology includes: that concentrated whey protein powder, whole milk powder are dissolved in whole water, stirs 15min under the conditions of 50 DEG C of water-bath. White granulated sugar and locust bean gum are uniformly mixed, are added in above-mentioned emulsion, insulated and stirred 10min is continued.Converted starch, lemon Acid, potassium sorbate, salt are uniformly mixed, and are added in above-mentioned emulsion, and 10min is stirred.Oily phase, Silverson cutter is added 7000rpm shears 1min, and then lotion crosses RVA homogenizer under the conditions of 200/40bar, and obtained lotion stirs in boiling water bath It is gelatinized 20min, pack, ice water cooling.

The partial size of concentrated whey protein powder variation is as shown in tables 2 and 3.

Flavor by 15 testing crews for sample carries out double blind evaluation experiment, carries out grading according to 1~5 score and beats Point, it makes even respectively.

Evaluation criterion: 5 points: milk taste is prominent, not the disagreeable taste of PURE WHEY；4 points: milk taste is prominent, does not have substantially The disagreeable taste of PURE WHEY；3: having some milk tastes, do not protrude, hence it is evident that have the bad flavor of PURE WHEY；2: milk taste is not Obviously, the bad flavor of PURE WHEY is prominent；1: there is no milk taste, the bad flavor of PURE WHEY is prominent.

Evaluation result is as shown in table 6.
