Description

Technical Field

[0001] This application relates to the field of food additive technology, and in particular to a neotame composition, an electronic atomizing liquid, and an electronic atomization system. Background Technology

[0002] Neotame (N-[N-(3,3-dimethylbutyl)-L-α-aspartic acid]-L-phenylalanine-1-methyl ester) is a functional sweetener with a pure, harmonious sweetness that is very close to aspartame, without the bitterness and metallic taste often found in other strong sweeteners.

[0003] Powdered neotame has good chemical stability, while liquid neotame is easily affected by factors such as pH, temperature, solvent, and reducing properties, leading to a decrease in stability. Neotame is the most commonly used high-intensity sweetener in traditional e-cigarettes. When neotame is diluted and added to the atomizing liquid, its stability is affected by system conditions and composition, and it becomes less flavorful over time. Summary of the Invention

[0004] Therefore, it is necessary to provide a neotame composition, an electronic atomizing liquid, and an electronic atomization system that can maintain sweetness for a long time.

[0032] This application provides a neotame composition comprising neotame, a neotame stabilizer, and a first solvent in a mass ratio of 1:(0.01~2):(0.1~40);

[0033] The neotame stabilizer includes a first stabilizing component, which includes one or two of carotenoids and rosemary extract.

[0034] The neotame composition provided in this application, through the combined use of neotame and a neotame stabilizer, utilizes the abundant natural polysaccharides in carotenoids and / or rosemary extract, which possess strong antioxidant properties to effectively improve the stability of neotame. After the rosemary extract exerts its effect, it produces the stimulating metabolite caffeic acid, which also has strong antioxidant activity.

[0035] Further, the neotame composition includes neotame and a neotame stabilizer in a mass ratio of 1:(0.2~1). Specifically, the mass ratio of neotame and the neotame stabilizer in the neotame composition may be, but is not limited to, 1:0.2, 1:0.225, 1:0.25, 1:0.275, 1:0.3, 1:0.325, 1:0.35, 1:0.375, 1:0.4, 1: 0.425, 1:0.45, 1:0.475, 1:0.5, 1:0.525, 1:0.55, 1:0.575, 1:0.6, 0.625, 1:0.65, 1:0.675, 1:0.7, 1:0.725, 1:0.75, 1:0.775, 1:0.8, 1:0.825, 1:0.85, 1:0.875, 1:0.9, 1:0.925, 1:0.95, 1:0.975 or 1:0.1.

[0036] In one specific example, the first solvent includes one or more of propylene glycol, glycerol, ethanol, and water.

[0037] Understandably, carotenoids can be extracted, but are not limited to, from carrots. Specific extraction methods include the following steps:

[0038] Carrots and water were mixed at a ratio of (80~120)g: (100~300)mL and treated at 50℃~90℃ for 5min~25min. The liquid was filtered out, centrifuged for 5min~15min, and the supernatant was filtered for the first time. Activated carbon was then mixed in, and the mixture was treated at 50℃~90℃ for 25min~60min. A second filtration was then performed to prepare the filtrate.

[0039] The preparation method of rosemary extract includes the following steps:

[0040] Rosemary was dried at a first temperature for a first time and then pulverized to prepare rosemary powder.

[0041] After mixing rosemary powder with a second solvent, the mixture is extracted and the liquid is filtered out.

[0042] In a specific example, the first temperature in the method for preparing rosemary extract is 40°C to 80°C; specifically, the first temperature may be, but is not limited to, 40°C, 45°C, 50°C, 55°C, 60°C, 65°C, 70°C, 75°C, or 80°C.

[0043] In a specific example, the first time in the preparation method of rosemary extract is 1h to 5h. Specifically, the first time can be, but is not limited to, 1h, 1.5h, 2h, 2.5h, 3h, 3.5h, 4h, 4.5h or 5h.

[0045] In one specific example, the mass ratio between rosemary powder and the second solvent is (2~20): (50~200), and further, the second solvent includes one or more of ethanol, water, glycerol and propylene glycol.

[0046] In one specific example, the neotame stabilizer also includes a second stabilizing component, which includes one or more of tea polyphenols, resveratrol, and tea polyphenol palmitate.

[0047] Because tea polyphenols have abundant phenolic hydroxyl groups in their structure, they can provide active hydrogen, reducing the generation of peroxide free radicals. Simultaneously, tea polyphenols easily aggregate at the oil-water interface, inhibiting lipid peroxidation and clearing chain reaction intermediates. Resveratrol is a non-flavonoid polyphenolic compound containing a stilbene structure. Phenolic compounds easily form conjugated systems, lowering the activation energy of the reaction and thus promoting synergistic effects.

[0048] In a specific example, the mass ratio of the first stable component to the second stable component is (1~3):(0.5~5). Understandably, the mass ratio of the first stable component to the second stable component can be, but is not limited to, 1:0.5, 1:1, 1:1.5, 1:2, 1:2.5, 1:3, 1:3.5, 1:4, 1:4.5, 1:5, 2:0.5, 2:1, 2:1.5, 2:2.5, 2:3, 2:3.5, 2:4.5, 3:0.5, 3:1, 3:2, 3:3.5, 3:4, or 3:5.

[0049] In one specific example, the second stable component is tea polyphenols.

Further, the second stabilizing component is tea polyphenols and tea polyphenol palmitate in a mass ratio of (1:1) to (3:1). Specifically, the second stabilizing component may be, but is not limited to, tea polyphenols and tea polyphenol palmitate in a mass ratio of 1:1, 1.1:1, 1.2:1, 1.3:1, 1.4:1, 1.5:1, 1.6:1, 1.7:1, 1.8:1, 1.9:1, 2:1, 2.1:1, 2.2:1, 2.3:1, 2.4:1, 2.5:1, 2.6:1, 2.7:1, 2.8:1, 2.9:1, or 3:1.

[0051] In one specific example, the second stabilizing component comprises a mixture of tea polyphenols and resveratrol. Further, the second stabilizing component is tea polyphenols and resveratrol in a mass ratio of (2:1) to (3:1). Specifically, the second stabilizing component may be, but is not limited to, tea polyphenols and resveratrol in a mass ratio of 2:1, 2.1:1, 2.2:1, 2.3:1, 2.4:1, 2.5:1, 2.6:1, 2.7:1, 2.8:1, 2.9:1, or 3:1.

[0052] In one specific example, the second stabilizing component comprises a mixture of resveratrol and tea polyphenol palmitate. Further, the second stabilizing component is resveratrol and tea polyphenol palmitate in a mass ratio of (1:1) to (2:1), specifically, the second stabilizing component may be, but is not limited to, resveratrol and tea polyphenol palmitate in a mass ratio of 1:1, 1.1:1, 1.2:1, 1.3:1, 1.4:1, 1.5:1, 1.6:1, 1.7:1, 1.8:1, 1.9:1, or 2:1.

[0053] In one specific example, the second stabilizing component comprises a mixture of tea polyphenols, resveratrol, and tea polyphenol palmitate. Further, the second stabilizing component is tea polyphenols, resveratrol, and tea polyphenol palmitate in a mass ratio of (1:1:1) to (3:1:1). Specifically, the second stabilizing component may be, but is not limited to, tea polyphenols, resveratrol, and tea polyphenol palmitate in a mass ratio of 1:1:1, 1.1:1:1, 1.2:1:1, 1.3:1:1, 1.4:1:1, 1.5:1:1, 1.6:1:1, 1.7:1:1, 1.8:1:1, 1.9:1:1, 2:1:1, 2.1:1:1, 2.2:1:1, 2.3:1:1, 2.4:1:1, 2.5:1:1, 2.6:1:1, 2.7:1:1, 2.8:1:1, 2.9:1:1, or 3:1:1.

[0054] Furthermore, by using a first stabilizing component in combination with a second stabilizing component, the neotame stabilizer not only effectively improves the stability of neotame through its excellent antioxidant properties, but also harmonizes the aroma of the e-liquid, enhances its naturalness, and increases its smoothness, thereby further improving the user experience as an e-cigarette e-liquid.

[0055] This application also provides a method for preparing the neotame composition as described above, comprising the following steps: mixing a neotame stabilizer and a first solvent, and then mixing the first solvent with neotame.

[0056] In a specific example, the neotame stabilizer and the first solvent were mixed at a mass ratio of (1~5): (75~90), ultrasonically treated at a temperature of 35℃~55℃, and then mixed with neotame.

[0057] Understandably, the neotame stabilizer and the second solvent can be mixed at, but not limited to, temperatures of 35°C, 36°C, 37°C, 38°C, 39°C, 40°C, 41°C, 42°C, 43°C, 44°C, 45°C, 46°C, 47°C, 48°C, 49°C, 50°C, 51°C, 52°C, 53°C, 54°C, or 55°C.

[0111] Compared to Comparative Example 1, the neotame retention rate in the nebulizer solutions of Examples 1-9 was significantly increased, with the difference reaching a statistically significant level. Especially by day 60, the difference in neotame retention rate between the Examples 1-9 and the Comparative Example reached a highly significant level. Compared to Comparative Example 1, the neotame retention rate of Examples 1-9 with added neotame stabilizer was approximately 6% higher on day 30 and approximately 7.42% higher on day 60. Furthermore, compared to Comparative Examples 2 and 3, the neotame retention rates of Examples 2 and 3 were 5.47% and 6.94% higher on days 30 and 60, respectively. Compared to Comparative Examples 4 and 5, the neotame retention rates of Examples 7 and 8 were 5.55% and 6.47% higher on days 30 and 60, respectively.

[0116] Compared with Comparative Examples 1-6, the atomized liquids of Examples 1-9 showed significantly higher sweetness after 60 days of storage. Furthermore, due to the retention of sweetness, the taste of the atomized liquids was also significantly improved, with better sweetness and aroma compared to the comparative examples. This demonstrates that the stabilizer provided in this application not only effectively improves the stability of the sweetener but also further enhances sensory evaluation.
