comparative example 1
Comparative example 1 differs from example 1 in that: the method of making preserved egg protein granules is different.
In this comparative example, the method for making preserved egg protein granules comprises the main steps of:
1) cleaning preserved egg protein, draining water, freezing at-18 deg.C for 20 hr, and pulverizing into 5 mesh granules;
2) And (3) baking the crushed preserved egg particles at 50 ℃ for 50min to obtain the preserved egg protein particles.
in the comparative example, when preserved egg protein granules are prepared, the preserved egg protein is not soaked in an aqueous solution added with ginger and vinegar, so that the preserved egg protein granules prepared after the later crushing and baking have heavier alkaline taste and fishy smell, and the overall taste of the preserved egg ice cream is poorer.
comparative example 2
comparative example 2 differs from example 1 in the method of making a slurry for a preserved egg yolk filling.
In this comparative example, the method for making a slurry for a preserved egg yolk filling mainly comprises the steps of:
1) Removing shell and egg white of fresh killed heart preserved egg, and leaving the preserved egg yolk;
2) pre-freezing the preserved egg yolk at-18 deg.C for 30 min;
3) Adding 1% of edible salt into the pre-frozen preserved egg yolk for premixing, pouring into a colloid mill, and crushing into 30 meshes to obtain the slurry of the preserved egg yolk filling.
When the preserved egg yolk paste is prepared in the comparative example, cuttlefish juice is not added during the processing of the preserved egg yolk, so that the crushed preserved egg yolk paste in the later period has uneven color and poor appearance and taste, and the whole taste of the preserved egg ice cream is poor.
