Abstract

The invention discloses an embedding material of sulforaphane. The embedding material is prepared from the following components of low-methoxy pectin, pullulan, glutenin, sucrose fatty acid ester, sulforaphane and calcium ions. The embedding material of the sulforaphane has excellent stability, and can slow down the decomposition speed of the sulforaphane. The invention further discloses a preparation method of the embedding material of the sulforaphane. The preparation method comprises the following steps of step I, uniformly mixing water with the calcium ions and the low-methoxy pectin in the mass ratio of the low-methoxy pectin to the water being 1: (20-25); step II, adding the pullulan, the glutenin and the sucrose fatty acid ester, and performing uniform mixing; step III, adding the sulforaphane, and performing uniform stirring in the same clock direction; and step IV, performing drying to obtain the powder of the embedding material of the sulforaphane. The preparation method is simple, and the prepared embedding material of the sulforaphane is good in stability.

Description

technical field [0001] The invention relates to the technical field of sulforaphane processing. More specifically, the present invention relates to an embedding material of sulforaphane and a preparation method thereof. Background technique [0002] Sulforaphane (SF), chemical name 1-isothiocyanate-4-methanesulfonyl butane, is a sulfur-containing plant secondary metabolite of glucosinolates in plants under the action of myrosinase . It belongs to the class of isothiocyanates and is the strongest anticancer ingredient found in vegetables so far. Sulforaphane is effective in preventing the occurrence of various cancers and inducing apoptosis of cancer cells, such as gastric cancer cells and colon cancer cells. The extraction technology of sulforaphane is very mature, but due to the nature of sulforaphane itself, it is not easy to produce and preserve. Sulforaphane is chemically unstable and easy to degrade. For example, when the temperature is higher than 180°C, it starts...
