Benefits of technology

Inventors discovered that they developed an improved process called flash evaporation (flash vaporization) used during production of crude or semi-refractory vegetable products like citrus fruits. By combining these two methods together, it provides more precise results than just simply steaming them out without adding any chemical substances. It also makes better use of valuable flavor compounds from the plant itself while reducing environmental concerns associated therewith. Overall, this new technology allows us to produce high quality bastardainton seed oleoresin at very affordable prices compared to current techniques such as water washing and milling processes.

Problems solved by technology

This patents discuss two technical problem addressed during this patented process: how to efficiently separate crude or semi-freshly extracted vegetable essence into pure ones without leaving any unwanted substituants like dirt or debris; while still maintaining their beneficial properties such as scentings and taste qualifications.

The second connecting pipe 9 includes a vertical pipe and an elbow, and the lower connecting port 7 is set Below the vertical pipe, the bent pipe is connected to the middle part of the straight pipe 4, and a third connecting pipe 10 is arranged on the upper part of the vertical pipe, and the third connecting pipe 10 is connected to the top of...

Embodiment 2

[0032] With the fresh bergamot essential oil obtained in Example 1, according to 0.001‰ of the quality of shredded tobacco, absorb the essential oil with a micro-injector, and use an edible alcohol solution with a volume fraction of 75% to prepare a solution with an essential oil concentration of 0.2 mg / ml and spray it on shredded tobacco for rolling After the finished cigarettes are balanced for 48 hours at constant temperature (22±1°C) and constant humidity (relative humidity: 60±2%), sensory evaluation is carried out according to the method of evaluation and smoking in patent 201110335098.2. The results of sensory evaluation and smoking are as follows: compared with the pre-flavored cigarettes without adding essential oils, the amount of aroma is slightly increased, the elegance and elegance are significantly increased, and the harmony is good.

Embodiment 3

[0034] With the fresh bergamot essential oil obtained in Example 1, according to the quality of 0.002‰ of cut tobacco, absorb the essential oil with a micro-injector, and use an edible alcohol solution with a volume fraction of 75% to prepare a solution with an essential oil concentration of 0.2 mg / ml and spray it on the cut tobacco for rolling. After the finished cigarettes are balanced for 48 hours at constant temperature (22±1°C) and constant humidity (relative humidity 60±2%), sensory evaluation is carried out, according to the evaluation method of patent 201110335098.2. The results of sensory evaluation and smoking are as follows: compared with the pre-flavored cigarettes without adding essential oils, the amount of aroma slightly increases, the richness slightly increases, the elegance and elegance increase, and the harmony is better, but the irritation is slightly increased Big.

Abstract

The invention relates to a method for extracting essential oil from fresh bergamot. The method comprises the following steps: (1) weighing the fresh bergamot, immersing the fresh bergamot into saturated lime water for 24 hours, cleanly rinsing with flowing clean water, and dripping; squeezing treated bergamot peels, so as to obtain an oil-water mixture; (2) extracting volatile oil from the obtained oil-water mixture according to a steam distillation method, adding a proper amount of anhydrous sodium sulfate into the collected volatile oil to dehydrate, and separating, thereby obtaining the bergamot essential oil. According to the method, the fresh bergamot serves as a raw material, and the characteristics that the squeezing method is simple and feasible and the steam distillation method is used for carrying out refined extraction are combined, thus the disadvantages of a pure squeezing method that the accuracy is low and the emulsification is difficult to separate are overcome, and the advantages of simplicity and high efficiency of the steam distillation method are combined, so that the bergamot essential oil extraction method which is creatively invented is rapid and efficient.
