Description

Technical Field

[0001] This invention belongs to the field of food flavoring technology, specifically relating to a scallion oil flavoring and its preparation method. Background Technology

[0002] Green onions, as an important spice, are beloved by consumers for their unique fresh, spicy, and sweet flavor, and are widely used in instant noodle seasonings, compound seasonings, meat products, puffed foods, and the catering industry. Currently, green onion-flavored products are mainly obtained through green onion powder and simply blended green onion flavorings. While green onion powder has a realistic flavor, its flavor and intensity are unstable, easily spoiled, and greatly affected by processing methods, seasons, and origins. Existing green onion flavorings have relatively simple flavor profiles and lack naturalness.

[0003] Therefore, it is imperative to develop a scallion oil flavoring that can simulate the complete flavor profile of natural scallions. Summary of the Invention

[0009] In some embodiments of the present invention, the scallion oil is prepared by the following method: When scallions are extracted using soybean oil, the oil and water separate into layers, and the upper oil phase is scallion oil.

[0010] In some embodiments of the present invention, the scallions are fresh scallions.

[0011] In some embodiments of the present invention, the mass ratio of the scallions and soybean oil is 1:1 to 2.

[0012] In some embodiments of the present invention, an antioxidant is added during the extraction.

[0014] Specifically, the preparation method of the scallion oil of the present invention is as follows: Select fresh green scallions, wash them and air dry them naturally until the surface moisture content is ≤5%. Chop the white part of the scallion into 2-3mm pieces and the green part into 1-2cm pieces. Add 1 part soybean oil and 0.02% antioxidant, stir evenly, and let it soak naturally for 4 days. Pass the mixture of green scallions and oil through a 100-mesh sieve to remove the residue. Weigh the filtrate and add 1% fine salt (40 mesh) by weight. Stir evenly and let it stand for 24 hours. Wait for the oil and water to separate. Remove the water in the lower layer and take the upper oil phase as the scallion oil.

[0015] In some embodiments of the present invention, the scallion flavoring comprises, by weight, 0.3-1.2 parts of 3-mercapto-2-methylpentanol, 0.1-1 parts of propanethiol, 0.06-0.4 parts of diallyl sulfide, 0.2-2 parts of dipropyl trisulfide, 0.1-1 parts of methylpropyl disulfide, 0.1-1 parts of dipropyl disulfide, 0.0005-0.01 parts of 2,4-heptadienal, 0.0005-0.003 parts of leaf alcohol, 0.005-0.06 parts of dibutyl sulfide, 0.01-0.1 parts of 2-mercapto-3-butanol, 0.001-0.01 parts of 2,4,5-trimethylthiazole, 0.005-0.024 parts of trimethylpyrazine, 20-60 parts of scallion oil, and 20-40 parts of soybean salad oil.

[0016] By weight, the scallion flavoring comprises 0.5-1.2 parts of 3-mercapto-2-methylpentanol, 0.2-1 parts of propanethiol, 0.08-0.4 parts of diallyl sulfide, 0.4-2 parts of dipropyl trisulfide, 0.2-1 parts of methylpropyl disulfide, 0.2-1 parts of dipropyl disulfide, 0.001-0.01 parts of 2,4-heptadienal, 0.001-0.003 parts of leaf alcohol, 0.01-0.06 parts of dibutyl sulfide, 0.03-0.1 parts of 2-mercapto-3-butanol, 0.002-0.01 parts of 2,4,5-trimethylthiazole, 0.008-0.024 parts of trimethylpyrazine, 30-60 parts of scallion oil, and 30-40 parts of soybean salad oil.

[0024] In some embodiments of the present invention, the scallion oil flavoring accounts for 0.1% to 5% of the product by mass.

[0025] In some embodiments of the present invention, the product is food, food additive, or seasoning.

[0026] The beneficial effects of this invention are: 1) Green onions are extracted naturally at low temperature using vegetable oil, which can effectively avoid the destruction of heat-sensitive components, retain the original fragrance of fresh green onions, and eliminate any burnt or off-flavors.

[0027] 2) This invention uses a combination of 3-mercapto-2-methylpentanol, propanethiol, diallyl sulfide, dipropyl trisulfide, methylpropyl disulfide, and dipropyl disulfide to form the main aroma of scallions. At the same time, 2,4-heptadienal and leaf alcohol are added to give scallions a fresh aroma, and scallion oil is added to enhance the base aroma. Other excipients such as dibutyl sulfide, 2-mercapto-3-butanol, 2,4,5-trimethylthiazole, and trimethylpyrazine are also added, which not only makes the aroma of the fragrance more coherent, but also more realistic and natural.

[0040] Application Example 1: Scallion Flavoring Seasoning The scallion oil flavoring from Example 1 was applied to scallion-flavored seasonings, and the formula is shown in Table 1.

[0041] Table 1. Scallion-flavored seasoning recipe

[0042] To prepare the scallion-flavored seasoning, simply mix all the ingredients in the recipe thoroughly.

[0043] Using the same formula and preparation method, flavorings in proportions 1 to 3 were applied to scallion-flavored seasonings.

[0044] Evaluation of effectiveness: A sensory evaluation panel of 50 people scored the scallion-flavored seasonings prepared in Example 1 and Comparative Examples 1-3 based on the aroma, taste, realism, and liking of scallions. The average evaluation results are shown in Table 2.

[0045] Table 2. Rating scores for scallion-flavored seasoning (out of 10)

[0046] As shown in Table 2, the difference between Comparative Example 1 and Example 1 is that Comparative Example 1 did not contain 3-mercapto-2-methylpentanol, propanethiol, diallyl sulfide, dipropyl trisulfide, methylpropyl disulfide, and dipropyl disulfide. This resulted in the scallion oil flavoring in Comparative Example 1 lacking a full-bodied scallion aroma, making it less flavorful when used in seasonings. The difference between Comparative Example 2 and Example 1 is that Comparative Example 2 did not contain 2,4-heptadienal and leaf alcohol, resulting in insufficient freshness when used in seasonings. The difference between Comparative Example 3 and Example 1 is that no scallion oil was added, resulting in a less desirable scallion flavor when used in seasonings. Table 2 shows that the scallion oil flavoring prepared in Example 1 of this invention is better than that prepared in the comparative examples, and it received a higher score. This indicates that the scallion oil flavoring prepared by this method has a pure and realistic scallion flavor and can be well applied to meet the needs of consumers.

[0047] The above embodiments have provided a detailed description of the embodiments of the present invention. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. Furthermore, unless otherwise specified, the embodiments of the present invention and the features thereof can be combined with each other.
