(3) 10 celeriacs are put into Texture instrument (TA plus A/MC, French fries probe), poly- probe distance at random after off the pot 5cm, time control are popped one's head in and are carried out downwards with 1cm/s speed in 70s, startup test, go deep into celery 5mm and stop test, display is most Peak ordinate (g) is hardness;
(4) celery brightness after while being cooked using the test of portable chromatism test instrument (chromatogram CS-210).Detection method is Lab Method is the chromatic value for representing object color;Wherein L*:Represent shading value (black and white).
According to above step, grease in embodiment 3 is selected to combine in 1-10, embodiment 6 in grease combination 24, embodiment 5 Grease combination 16, mouthfeel hardness, brightness such as table 4:
Table 4 cooks celery difference grease combination mouthfeel, luminance difference
As shown in Table 4, the celery mouthfeel hardness cooked using rapeseed oil is maximum (2554g/10 roots), adds oleostearin 1 Mouthfeel is apparent soft glutinous afterwards, and stiff sense is eased, and after adding 10% oleostearin 1, hardness declines 7.9% (2353g/10 roots), After the oleostearin 1 of addition 20%, 30%, 40%, celery hardness declines 14.2% (2192g/10 roots), 25.1% respectively (1913g/10 roots), 17.7% (2102g/10 roots) also has soft glutinous effect, but be not as bright as oleostearin 1 after adding 30% butter 1 It is aobvious.And the palm stearin for adding 30% does not have soft glutinous effect (2502g/10 roots).Meanwhile after adding in a certain amount of oleostearin 1, tool There is apparent " colouring " effect, using rapeseed oil as with reference to (20.35), brightness promotes 19.1% (10%), 34.4% respectively (20%).But after adding to 30% oleostearin 1, luminance raising 39.6%, after adding to 40%, brightness improves 29.2%, but butter After stearine content is excessively high, brightness decreases.30% butter 1 of similary addition can promote brightness 8.8%, but add 30% palm After tristearin, celery brightness is without promotion or even is declined slightly (20.11).
Meanwhile 80% combination of the soybean oil with 20% oleostearin 3 and 60% seed oil of sunflower combine nothing with 40% oleostearin 2 By being in hardness and brightness, there is good performance.
Based on embodiment 4,5,6, it is known that by adding oleostearin, chili oil oil content can be improved.Meanwhile it cooks green Enable to green vegetables more soft glutinous after dish, without stiff sense, green vegetables brightness also increased.Synthesis practices, and adds 10-70% Oleostearin, effect are preferable.
It should be understood that after the above for having read the present invention, those skilled in the art can make the present invention various Change or modification, such equivalent forms equally fall within the application range as defined in the appended claims.
