Description

Improve the nanometer emulsion and preparation method thereof of fruits and vegetables class carotenoid biosynthesis utilization rate
Technical field
The present invention relates to a kind of nanometer emulsion and preparation method thereof for improving fruits and vegetables class carotenoid biosynthesis utilization rate.
Background technique
At the beginning of last century, since vitamin A is found, precursor substance of the carotenoid as vitamin A is especially planted Important function of the carotenoid in object source in human diet is also gradually shown.Studies have shown that carotenoids are known as Beneficial to human health, after intake carotenoid enters human body, being converted into vitamin A has significantly cardiovascular disease and cancer Prevention effect.There are carotenoid in a large amount of fruits and vegetables, wherein with beta carotene, lutein, lycopene, hidden The substances such as yellow matter are representative, and existence form within plant tissue is different.In many presentation yellow, orange and red plants In, carotenoid is present in a variety of manners in the chromoplast of plant tissue.As distinguished in the chromoplast of carrot and tomato Beta carotene and lycopene and its derivative containing larger volume crystal habit;And the carotenoids in pawpaw and mango Element is with liposoluble state or the accumulation of liquid crystals shape in a large amount of minimum spherical or tubulose chromoplast structure.It can be seen that fruits and vegetables The different existence forms of carotenoid determine its process discharged from plant tissue, this process also exactly influences its life One key factor of object utilization rate.In addition to this, from fruit and vegetable materials carotene after being discharged in raw material, through human body mouth It is absorbed in small intestine to be efficiently used by body after chamber, stomach, small intestine alimentary canal.Therefore, based on the rouge of carotenoid The dissolution characteristics of dissolubility, enter the carotenoid in duodenum must in diet lipid material, in digestive juice The specific micellar conformation of the formation such as cholate, lipophilic and amphiprotic substance can be efficiently used by human body.
Carotenoids procatarxis existence form and deliquescent feature, utilization rate in diet is extremely low.It is usually used in improving it The main method of bioavailability is to take in grease simultaneously, and main form has: using grease cook, mayonnaise modulation, with contain There are the food such as dairy products of lipid while eating or coming out the Extraction of carotenoid pigment in fruit and vegetable materials, as food additive Add agent or functional food.However, grease is also easy to produce harmful substance at high temperature in gastronomical process;Fat content is higher in mayonnaise , easily there is the phenomenon that grease excess intake in (generally 70% or so or higher);From functional food or by nutrition fortifier It is also relatively limited to take in carotenoid;In addition, there may be interactions for material composition in fruit and vegetable materials and dairy products, thus Influence the utilization of other nutriments.Fruit-vegetable food is the important component of ordinary meal, how to improve the class in fruits and vegetables source Carotenoid biosynthesis utilization rate plays a significant role to the diseases such as body vitamin A intake, prevention angiocarpy and cancer are improved. The invention discloses one kind can be improved fruits and vegetables class carotenoid biosynthesis utilization rate, fat content it is low, can be wide in food processing Nanometer emulsion of general application and preparation method thereof.Preparation gained nanometer emulsion particle diameter is small, stability is good, can be used as food additive Add agent carrier to be applied in the fabricated products such as beverage made of fruits or vegetables, can be used for the carrier of fruits and vegetables seasoning, substitution tradition sand high in fat Sauce is drawn, thus when improving edible fruits and vegetables, carotenoid bioavailability.
