Production Process

1. Water formulation

With almonds as raw material, the best extraction process is: extraction time 20 min, solid liquid ratio 1:10, immersion time 30min, extraction 2 times, this method bitter almond glycoside yield is close to 3.2%. Raw peach kernels as raw materials, the use of hot water directly extracted, extract in the bitter almond glycoside content is cold water first dipped after lifting 2 times, water, extraction time and extraction times on the extraction rate of bitter almond glycoside has no significant effect, suggesting that raw peach kernels in bitter almond glycoside is more suitable for direct extraction with hot water. Based on almonds as raw material, comparing the effects of distilled bitter almond water method, reflux cooking method and alcohol tip method on the extraction rate of bitter almond glycoside, the results showed that the extraction rate of bitter almond glycoside was 95.77 percent when distilled bitter almond water method was used, which was significantly higher than that of reflux frying method 55.61 percent and alcohol-based bitter almond glycoside method 64.88 percent.

2. Alcohol reference

Based on apricot pollen, the waterless ethanol was used to fix the liquid ratio of 1:7, ultrasound 20 min, and extract 12 h, which was 6.1% of the extraction rate of bitter almond glycoside. With bitter almonds as raw material, the use of bitter almonds is easily soluble in thermal ethanol, slightly soluble in the nature of cold ethanol to extract bitter almond glycosides, the results show that plus 6 times 95% ethanol extract 1h, a total of 2 times, to bitter almonds coarse Crude products with aqueous ethanol with a solid liquid ratio of 1:30 recrystallization 3 times purification, this method bitter almond glycoside extraction rate of 92.47%, transfer rate of 45.92%.
