preparation example Construction

[0027] see figure 1 , the preparation method of the compound with caramelized butter flavor of one embodiment is a preparation method of the compound with caramelized butter flavor of the above-mentioned embodiment, comprising the following steps:

[0028] Step S110: react phenylacetic acid with thionyl chloride to obtain phenylacetyl chloride.

[0029] Wherein, the structural formula of phenylacetyl chloride is as follows:

[0030] Specifically, the molar ratio of phenylacetic acid to thionyl chloride is 1:1.05˜1:1.5. In one embodiment, in the step of reacting phenylacetic acid with thionyl chloride, phenylacetic acid is firstly added to the reaction vessel, and then the thionyl chloride is slowly added. Since the reaction between phenylacetic acid and thionyl chloride is relatively fast, thionyl chloride is slowly added dropwise in the reaction process to avoid the reaction being too fast and at the same time producing a large amount of tail gas which is difficult to com...

Embodiment 1

[0055] The preparation process of the compound with burnt cream taste of the present embodiment is as follows:

[0056] (1) preparation of phenylacetyl chloride:

[0057]

[0058] In 10L reactor, add phenylacetic acid (2.5L), slowly add thionyl chloride (1.5L), be warming up to 78 ℃ of reaction after dripping finishes, the tail gas that produces in the reaction process is 10% sodium hydroxide with mass concentration The aqueous solution was absorbed, stirred for 1 hour, and then distilled under reduced pressure to obtain phenylacetyl chloride (3.0 kg).

[0059] (2) preparation of furfuryl thiophenylacetate:

[0060]

[0061] In 10L reactor, add furfuryl mercaptan (2.0L, commercially available Hubei Hongxin Ruiyu Fine Chemical Co., Ltd.), under 25 ℃ of conditions, slowly add phenylacetyl chloride (3.0kg) dropwise, and react 3 hours, the tail gas produced in the reaction process was absorbed with an aqueous sodium hydroxide solution with a mass concentration of 10%. Aft...

Embodiment 2

[0070] The preparation process of the compound with burnt cream taste of the present embodiment is as follows:

[0071] (1) preparation of phenylacetyl chloride:

[0072] In 10L reactor, add phenylacetic acid (2.5L), slowly add thionyl chloride (1.5L), be warming up to 70 DEG C of reaction after dripping finishes, the tail gas that produces in the reaction process is 10% sodium hydroxide with mass concentration The aqueous solution was absorbed, stirred for 2 hours, and then distilled under reduced pressure to obtain phenylacetyl chloride (3.0 kg).

[0073] (2) preparation of furfuryl thiophenylacetate:

[0074] In the 10L reaction kettle, add furfuryl mercaptan (2.0L, commercially available from Hubei Hongxin Ruiyu Fine Chemical Co., Ltd.), under 30 ° C, slowly add phenylacetyl chloride (3.0kg) dropwise, and react 2 hours, the tail gas produced in the reaction process was absorbed with an aqueous sodium hydroxide solution with a mass concentration of 10%. After the complet...

Abstract

The invention relates to a compound with scorch cream flavor as well as a preparation method and an edible essence. The compound with scorch cream flavor has a structural formula shown in the specification, the aromatic furfuryl ester compound has fragrance different from that of a traditional aliphatic furfuryl ester compound, has special caramel and milk fragrance caramel cream flavor body fragrance, has fragrance intensity slightly higher than that of furfuryl thioacetate, has fragrance complexity close to that of furfuryl mercaptan, and can be used for flavoring foods.

Description

technical field [0001] The invention relates to the field of chemical synthesis, in particular to a compound with a burnt cream taste, a preparation method thereof and an edible essence. Background technique [0002] In the detection of sesame oil components, it was found that sesame contains many furfuryl thio compounds, most of which have coffee or sesame-like aroma characteristics. Among them, furfuryl mercaptan is commonly known as coffee aldehyde, which is mainly used to impart coffee-like top and body fragrance to food, while the fatty acid esterification product of furfuryl thiol has a softer aroma and is often used for coffee-like flavor body fragrance, such as sulfuric acid. Furfuryl acetate and thiopropionate are widely used in food flavoring. However, the aroma characteristics of the traditional esterification products of furfuryl thiol are all coffee-like, and the aroma is single. SUMMARY OF THE INVENTION [0003] Based on this, it is necessary to provide a n...
