Description
Technical Field
The invention relates to the field of zinc-rich vegetable oil, and mainly relates to an efficient preparation process of zinc-rich camellia seed oil.
Background
Zinc is a necessary trace element for human body, which cannot be synthesized in the body and can be supplied only by food. Zinc plays an important role in promoting human development, enhancing immunity, maintaining normal appetite of human bodies and the like. Zinc deficiency can cause various diseases, and especially has adverse effects on children, the elderly, pregnant women, etc. The vegetable oil is a necessity of human daily life, is an important source of human nutrient substances, and the deficiency of adjusting nutrient elements by taking high-quality edible vegetable oil is an important means for guaranteeing human health.
The oil tea is a unique woody oil plant in China, and researches show that the oil tea has a zinc-rich effect. The camellia oleosa seed oil is excellent edible vegetable oil, the content of unsaturated fatty acid exceeds 90%, particularly the content of oleic acid reaches about 80%, and the camellia oleosa seed oil is widely concerned as high-grade vegetable oil. The camellia seeds are mainly used for preparing crude oil through steaming, frying and squeezing, and further refined through degumming, alkali refining, decoloring, deodorizing, winterizing and the like so as to meet the requirements of national first-grade edible oil. We find that in the refining process, fat accompanying substances such as tocopherol and the like and nutrient elements such as zinc and the like lose more than 20-50%, and the nutritional value of the camellia seed oil is influenced.
Disclosure of Invention
The invention provides an efficient preparation process of zinc-rich camellia seed oil, aiming at solving the problem of large zinc element loss in the traditional preparation process of camellia seed oil.
The object of the present invention is achieved by the following technical means. An efficient preparation process of zinc-rich camellia seed oil is characterized in that on the basis of controlling the quality (acid value and peroxide value) of camellia seeds, a temperature gradient drying-shell-kernel ratio regulation and control technology is applied to carry out camellia seed squeezing treatment, the colloid content and color in oil are reduced, a citric acid-saturated salt water coupling low-loss degumming technology is applied, and the efficient preparation process of the zinc-rich camellia seed oil is established. The method comprises the following specific steps:
(1) selecting oil tea seeds: selecting the camellia seeds which are completely mature, have full seeds, have an oil acid value not more than 2mgKOH/g and a peroxide value not more than 10 mmol/kg;
(2) carrying out temperature gradient drying and shell-kernel ratio regulation and control to carry out camellia seed squeezing treatment: processing the camellia seeds for 10-30 minutes at 90-105 ℃, then drying the camellia seeds to 5-10% of water at 60-75 ℃, shelling the camellia seeds, adjusting the shell-kernel ratio to 20-50%, and filtering squeezed crude oil;
(3) coupling citric acid-saturated salt water to remove degumming at low loss: pumping the filtered crude oil into a degumming tank after squeezing, adding 45-55 wt% citric acid with 0.05-0.2 wt% of oil, treating at 40-70 deg.C for 45-90 min, heating to 60-80 deg.C, adding 70-90 deg.C salt water with 5-15 wt% of oil, washing for 2 times, dewatering and drying until no bubbles are formed on the surface of the oil.
Furthermore, after the step (3), winterization, dewaxing and fine filtration are carried out.
The invention has the beneficial effects that: the invention takes camellia seeds as objects, establishes the high-efficiency preparation process of the zinc-rich camellia seed oil by controlling the quality of the camellia seeds and the oil preparation process, and has the characteristics of low energy consumption, small loss of the camellia seed oil, less nutrient loss, excellent quality and the like.
