A bee bread containing a base material of the bee bread, the hydrophilic colloid, ethanol and water, and is prepared according to a certain preparation method. The bee bread containing the astaxanthin and the hydrophilic colloid has the advantages of long preservation time and small nutrient loss. The bee which are fed with the bee bread for a long time can effectively increase the yield of royal jelly and the number of larvae, and extend the life.

Bee bread containing astaxanthin and hydrophilic colloid and preparation method thereof

A limonin extraction method, comprising the following steps: step one, raw material extracting or juicing: directly soaking raw material in water or using a presser to directly juice the raw material to obtain the extract; step two, adding salt and adjusting pH: adding a sulfate solid material or saturated sulfate solution to the extract; adjusting pH to 3-7; step three, heating and preserving heat: heating to 20&#xb0; C.-100&#xb0; C. and keeping at the temperature for 10 minutes-110 minutes; step four, centrifuging: centrifuging for 10 minutes at a rotational speed of 2500&#xd7;g, and obtaining limonin precipitation. Compared with a traditional method, the raw material in the present invention can directly use the extract liquid or juicing liquid without drying, and recover most limonin in water using a precipitation method without complicated apparatus, and is easy to operate and has a low process cost.
