Problems solved by technology

However, when the moisture content is unevenly distributed in the tea seeds, even if the average total moisture content of the tea seeds is not high, the acid value of the tea seed oil squeezed out will be caused by the heating of the tea seeds with high moisture content during the frying process. and the peroxide value will increase greatly, and at the same time, the tea seeds with low moisture content are particularly easy to burn, which will lead to a substantial increase in the benzopyrene content of the extracted tea seed oil. In severe cases, the benzopyrene content may exceed the national edible oil standard. 20 to 30 times the limit value (10μg / kg)

Embodiment 1

[0021] (1) 500 kg of Camellia oleifera seeds were removed from the exocarp and impurity-removed and graded in a well-closed warehouse with improved airtightness, and the storage time was 24 hours;

[0022] (2) Supply hot air at a temperature of 42°C to the modified airtight warehouse during the storage process to ensure that the warehouse temperature is at 32°C during the storage process;

[0023] (3) Put the Camellia oleifera seeds stored out of the warehouse in a mixer with a heating device, a stirring device and a spray head, heat to 50° C. and keep stirring for 5 hours. During the heating process, the temperature at which 2% of the total mass of the tea seeds is sprayed is 50℃ hot water;

[0024] After balance, the moisture content of Camellia oleifera seeds was 9.5%, and the difference between the highest and lowest moisture content of 30 sampling points was 0.12%, and the difference before balance was 1.8%.

Embodiment 2

[0026] (1) store 500kg of Camellia oleifera seeds that remove the exocarp and remove impurities and classify with a modified well-sealed silo, and the storage time is 36h;

[0027] (2) Supply hot air at a temperature of 40°C to the modified airtight warehouse during the storage process to ensure that the warehouse temperature is at 31°C during the storage process;

[0028] (3) Put the Camellia oleifera seeds stored out of the warehouse in a mixer with a heating device, a stirring device and a spray head, heat to 45°C and keep stirring for 4 hours. During the heating process, the temperature of 1.5% of the total mass of the tea seeds is properly sprayed 45 ℃ hot water;

[0029] After balance, the moisture content of Camellia oleifera seeds was 8.2%, and the difference between the highest and lowest moisture content of 30 sampling points was 0.1%, and the difference before balance was 1.7%.

Embodiment 3

[0031] (1) store 500kg of Camellia oleifera seeds with removed exocarp and impurity-removed grades in a large container with improved airtightness, and the storage time is 48h;

[0032] (2) During the storage process, supply hot air with a temperature of 37°C to the modified airtight chamber to ensure that the warehouse temperature is at 30°C during the storage process;

[0033] (3) Put the camellia seeds stored out of the warehouse in a mixer with a heating device, a stirring device and a spray head, heat to 40°C and keep stirring for 3 hours. During the heating process, the temperature at which 1% of the total mass of the tea seeds is sprayed is 40°C hot water;

[0034] After balance, the moisture content of Camellia oleifera seeds was 7.2%, and the difference between the highest and lowest moisture content of 30 sampling points was 0.05%, and the difference before balance was 1.6%.

Abstract

The invention discloses a method for controlling moisture content of camellia oleifera seeds. Before frying the seeds, the camellia seeds that have been removed from the peel are graded and stored in a constant temperature airtight storage combined with the method of spraying at an appropriate temperature to make the moisture content in the camellia seeds even, so that the same batch of tea seeds can be guaranteed during the frying process It will not cause high acid value and high peroxide value due to high moisture content, nor will it cause high benzopyrene content due to low moisture content, so as to ensure low benzopyrene content, low acid value, High-quality edible tea seed oil with low peroxide value, high edible safety, strong aroma, high content of vitamin E and camellia oleifera polyphenols, and moderate color can meet the national high-quality edible vegetable oil (grade 1-2) standard, and can guarantee Store at room temperature in an airtight state for 1 to 2 years.

Description

technical field [0001] The invention relates to a method for controlling the water content of camellia oleifera seeds for producing camellia oil with low benzopyrene content and high safety, and belongs to the field of intensive processing of agricultural products. Background technique [0002] Camellia oleifera seed is an important edible oil raw material in southern my country, generally with exocarp and camellia oleifera seed shell. Camellia oleifera oil is rich in unsaturated fatty acids such as linoleic acid, and is rich in physiologically active substances such as polyphenols and vitamin E. Its nutritional and physiological effects are superior to vegetable oils such as olive oil, soybean oil, rapeseed oil, and peanut oil. superior to animal oil. my country's edible oil mainly relies on imports. Therefore, the use of the southern hills and mountains to develop Camellia oleifera forests and thus obtain rich tea seed oil not only solves the shortage of edible oil resour...
