Embodiment 1

[0016] The preparation of lotus extract, the steps are as follows: 1) fresh lotus and lotus leaves were extracted with petroleum ether for 36 hours, the weight ratio of lotus and lotus leaves was 1:0.3, and the addition of petroleum ether was the total weight of lotus and lotus leaves 6 times of that, and take the filtrate after filtering the extract; 2) Use a rotary evaporator to remove petroleum ether under reduced pressure from the filtrate. Condenser and receiver use brine calcium chloride to condense and keep warm respectively. The temperature of brine calcium chloride is -9°C, and the filtrate is concentrated until it is semi-solidified to obtain the primary extract, which is placed at a low temperature of -60°C. Sterilize for 0.6 hour to obtain the finished lotus extract.

Embodiment 2

[0018] The preparation of lotus extract, the steps are as follows: 1) fresh lotus and lotus leaves were extracted with petroleum ether for 24 hours, the weight ratio of lotus and lotus leaves was 1:0.3, and the addition of petroleum ether was the total weight of lotus and lotus leaves 8 times of that, and take the filtrate after filtering the extract; 2) Use a rotary evaporator to remove petroleum ether under reduced pressure from the filtrate. Condenser and receiver are condensed and kept warm with brine calcium chloride respectively. The temperature of brine calcium chloride is -11°C, and the filtrate is concentrated until semi-solidified to obtain the primary extract, which is placed at a low temperature of -45°C. Sterilize for 0.8 hours to obtain the finished lotus extract.

Embodiment 3

[0020] The preparation of lotus extract, the steps are as follows: 1) fresh lotus and lotus leaves were extracted with petroleum ether for 30 hours, the weight ratio of lotus and lotus leaves was 1:0.5, and the addition of petroleum ether was the total weight of lotus and lotus leaves 5 times, take the filtrate after filtering the extract; 2) Use a rotary evaporator to remove petroleum ether under reduced pressure from the filtrate. Condenser and receiver are condensed and kept warm with brine calcium chloride respectively. The temperature of brine calcium chloride is -8°C, and the filtrate is concentrated until semi-solidified to obtain the primary extract, which is placed at a low temperature of -55°C. Sterilize for 1 hour to obtain the finished lotus extract.

Abstract

The invention discloses a preparation method of a lotus extractum, which comprises the following steps: 1) leaching fresh lotus and lotus leaf in a weight ratio of 1:(0.1-0.5) in petroleum ether for 24-48 hours, filtering the leaching solution, and taking the filtrate, wherein the petroleum ether is 5-8 times of the total weight of the lotus and lotus leaf; and 2) removing the petroleum ether from the filtrate with a rotary evaporator under reduced pressure to obtain a primary extractum, and carrying out low-temperature sterilization on the primary extractum to obtain the lotus extractum finished product. The petroleum ether used as the leaching agent can sufficiently extract the subtle fragrance component in the lotus petal and lotus leaf; the vacuum distillation for petroleum ether removal by using the rotary evaporator can effectively remove the petroleum ether; the whole preparation process is performed under lower temperature conditions, thereby maximally maintaining the aromatic components; and thus, the prepared lotus extractum is enriched with light subtle fragrance of lotus.

Description

technical field [0001] The invention belongs to the technical field of flavors and fragrances, and in particular relates to a preparation method of lotus extract. Background technique [0002] Lotus, also known as lotus, water hibiscus, etc., belongs to the order of water lilies, and is a perennial aquatic herbaceous flower of the lotus family. The petals of the lotus have a faint fragrance, and the leaves of the lotus are also full of a fresh and unique smell. People appreciate and taste the lotus fragrance, but they can only be near the lotus pond or bring the lotus back indoors, which is easily affected by seasons and time. If the lotus fragrance can be brought back indoors and made into a fragrance product, the economic value of the lotus can be fully developed. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a preparation method of lotus extract, so as to prepare lotus extract rich in lotus fragrance.
