Embodiment 1

[0014] see figure 1 , the inventive method is designed according to the synthesis pathway of 10-HDA in the honeybee body:

[0015] During the normal royal jelly production period, 48 production groups were randomly selected and divided into 8 groups on average, with 6 groups in each group. Before the experimental treatment, they were fed normal pollen feed. After the experiment started, 1%, 5%, 8%, and 10% citric acid or stearic acid were added to the pollen feed by mass percentage, and the operation continued for 9 days. The royal jelly produced before and after the addition of organic acids was sampled to determine the content of 10-HDA (results are shown in Table 1).

[0016]

[0017] As shown in Table 1, adding 1%, 5%, and 8% citric acid and stearic acid can significantly increase the 10-HDA content in royal jelly, while 10% citric acid or stearic acid has no significant effect. Among them, when the addition amount is 5%, the improvement effect is the best.

Abstract

The invention provides a method for improving 10-hydroxy-2-caproleic acid content of royal jelly. The method comprises the steps of adding 1 to 8% of citric acid or eleaostearic acid into pollen forage for supplying protein nutrients to bees, and continuously feeding bees with the pollen forage with citric acid or eleaostearic acid for 9 days. The method is designed according to a bee biology principle and a synthesis approach of 10-HDA in bees, is in accord with a biology principle, satisfies nutrition demands from bees, can obviously improve 10-HDA content of royal jelly, utilizes common food-grade edible substances as additives, does not produce food safety problems, has a short feeding period, simple operation processes and short onset time, and can be utilized in preparation of 10-hydroxy-2-caproleic acid-containing royal jelly.

Description

technical field [0001] The invention belongs to a method for extracting the content of royal jelly, and relates to a method for increasing the content of 10-hydroxy-2-decenoic acid (10-HDA) in royal jelly. Material-method of 10-HDA content in royal jelly. Background technique [0002] Royal jelly (royal jelly) is secreted by the hypopharyngeal and palatine glands of feeding bees, and is mainly used to feed the queen bee and bee larvae. It is a white or light yellow pulpy substance that is sour, astringent, spicy, sweet and slightly special aroma odor. The composition of royal jelly is very complex, containing proteins, lipids, carbohydrates, vitamins, minerals and many other active ingredients. [0003] 10-Hydroxy-2-decenoic acid (10-HDA) is the only natural substance found in royal jelly so far, so it is called "royal jelly acid". 10-HDA is the material basis of some functions of royal jelly, which has the functions of enhancing immunity, anti-radiation, anti-tumor and l...
