The relevant equipment and instrument types and methods used for the experiment are as follows:
water activity: analysis was performed using a swiss NOVASINA Lab Swift water activity meter;
moisture content: according to the method of GB/T5009.3 2016 moisture determination in food;
centrifugal test: the table centrifuge (Anke TDL 5A) tests the emulsion stability of the system, and the specific method is as follows: respectively weighing 150g of coconut-flavor rose jam in equal amount, centrifuging at 4000rpm for 15min, and observing the surface grease precipitation amount;
absorbance: measured using a You Nike (Shanghai) Instrument Co., ltd. UV-2100 UV-visible spectrophotometer;
peroxide value measurement: the peroxide value is measured according to the method of GB 5009.227-2016 national food safety standard.
Example Effect comparison
The experiments for absorbance measurement, peroxide value measurement and shelf life observation using the coconut rose pastes prepared in examples 1 to 3 and comparative examples 1 to 3 were as follows:
(1) Respectively dissolving the coconut-flavor rose sauce according to different sauce-water ratios, and measuring the absorbance of different antioxidants compounded in the coconut-flavor rose sauce, wherein the method comprises the following steps of:
1) Distilled water for the coconut rose pastes obtained in example 1 and comparative examples 1 to 3 was used as the coconut rose paste: distilled water = mass 1: dissolving in a ratio of 4 to 1:2;
2) Respectively adding distilled water into the coconut-flavor rose paste in a corresponding proportion, standing in a water bath at 60 ℃ for 4 hours, and stirring once every 20 minutes during the standing, so as to ensure that the coconut-flavor rose paste is fully dissolved in the distilled water to form a uniform and stable state;
3) The absorbance of the sample was measured at a wavelength of 530nm using a spectrophotometer, and the results are shown in FIG. 1.
Examples 1-3 and comparative examples 1-3 differ in the antioxidant added in step (3). As can be seen from fig. 1, the absorbance of example 1 is relatively high, which means that the color of the rose petals is relatively high, and the color of the pigments which are originally remained in the petals is relatively high and stable, so that the antioxidant used by the rosemary extract and the disodium edetate in combination is beneficial to color preservation of the rose petals.
(2) The measurement experiment of the peroxide value of the coconut rose jam is as follows:
the coconut rose pastes obtained in example 1 and comparative examples 1 to 3 were stored in an oven at 60℃for 20 days, and samples were taken every 5 days to measure the antioxidant value.
The results obtained are shown in Table 1 and are analyzed as follows: in the accelerated oxidation experiment of the coconut rose jam, the jam can have a certain rancidity due to the use of soybean oil with a certain proportion, the antioxidant effects of different antioxidants are different, the jam can have better taste and flavor due to the good antioxidant effect, the rancidity peculiar smell of grease can not be easily generated, and the compound effects are as follows from the data in table 1, namely, rosemary extract+disodium ethylenediamine tetraacetate, rosemary extract+disodium ethylenediamine tetraacetate+sodium sulfite, rosemary extract+sodium sulfite and disodium ethylenediamine tetraacetate+sodium sulfite.
Table 1 results of accelerated oxidation experiments with coconut-flavored rose jam
(3) The shelf life observation experiment of the coconut rose sauce is as follows:
1) Wrapping stuffing with the coconut-flavor rose sauce prepared in the embodiment 1 and the comparison examples 1-3 according to the ratio of skin to stuffing of 4:1, fermenting the bread with the stuffing in a fermenting box for at least 2 hours, baking in an oven with upper and lower fire temperatures of 190 ℃ and 160 ℃ respectively, taking out the bread after the surface of the bread is attractive golden yellow, returning to room temperature under natural conditions, sealing and packaging separately, and marking.
2) The stuffed bread is respectively stored in a constant temperature incubator at room temperature and at 37 ℃ in a dark place.
3) The observation and comparison are carried out within 6 months of preservation, and the states, the shades of colors, the migration of colors from jam to bread embryo and the like of the bread and the coconut rose jam are observed.
The results obtained are shown in Table 2. As can be seen from the data in table 2, the coconut-flavored rose jam obtained in example 1 maintained good state, mouthfeel, flavor and application effect over a 6 month shelf life, the rose petals in the raw material maintained relatively stable color through the initial color protection of the acid solution and the addition of the antioxidant effect, and minimal color migration in the baked product; the use of the antioxidant also plays a certain role in resisting oxidation to the grease in the jam, reduces the oxidation degree of the whole jam, and maintains the optimal state and index of the jam to the maximum extent.
Table 2 analysis of bread preservation results
In conclusion, the coconut rose jam prepared by the method can meet the requirements that the solid content is 60-61%, the water activity is 0.87-0.89, the jam shelf life is 6 months, and the shelf life of a baked finished product is 4-6 months; especially after the primary color protection is carried out by using 0.2% citric acid solution, the pigment of the rose petals can be kept as much as possible and kept stable under the condition of lower pH, the pigment of the rose petals can be further protected by adding rosemary extract and disodium ethylenediamine tetraacetate in the production process, the pigment of the rose petals can be stabilized again, meanwhile, the oxidation rancidity of soybean oil can be inhibited, the color of the coconut rose paste is more stable, and good color, taste and flavor states are kept in the storage period.
