Asparagus seed oil and preparation method thereof

Abstract

The invention relates to asparagus seed oil and a preparation method thereof. The method comprises the following steps: (1) cleaning asparagus seeds and drying until the water content of the asparagus seeds is between 6% and 10%; (2) steaming and frying the dried asparagus seeds until a fragrant smell is sent from the asparagus seeds, and then crushing the asparagus seeds; (3) carrying out oil squeezing on the crushed asparagus seeds in an oil press at a low temperature so as to obtain crude asparagus seed oil; (4) adding deionized water which is 50% of the weight of the oil and sodium bicarbonate which is 2% to 3% of the weight of the oil into the crude asparagus seed oil, heating to 60 DEG C to 70 DEG C, stirring for half an hour, standing for precipitating for 5 to 6 hours and filtering the oil so as to remove impurities; (5) adding citric acid which is 1.5% to 2% of the weight of the oil into the oil, dissolving the oil in a water phase, heating to 45 DEG C to 55 DEG C, stirring for half an hour, standing for separating out precipitates and filtering to remove the impurities; then carrying out oil-water separation so as to dehydrate the asparagus seed oil; and (6) decoloring and filtering the asparagus seed oil so as to obtain the asparagus seed oil. According to the prepared asparagus seed oil, the inherent flavor, the fragrant smell and the nutrient substances of the asparagus seed oil are retained to a maximum extent.

Description

technical field [0001] The invention belongs to the field of food processing, in particular to an asparagus seed oil and a preparation method thereof.

AI Technical Summary

Problems solved by technology

Asparagus seeds, as the second product of asparagus planting, are rich in nutrients and have high nutritional and health value. They have not been effectively used so far. On the one hand, the reason is that multi-generation hybridization cannot be used as seeds for seedling cultivation. On the other hand, it is about asparagus There are few related research results on the characteristics and processing technology of asparagus seeds, and there is a lack of technical support for the comprehensive processing and utilization of asparagus seeds
