3.07MDA ug/ml, peroxide value excursion is 3.23 ~ 3.75meq/kg, is illustrated with the change of storage time, oils and fatss body
Middle lipid hydroperoxide and secondary oxidative product assay variation tendency are steady, and oils and fatss body has higher non-oxidizability.
The oils and fatss body of fresh preparation is carried out into treatment of different temperature, its emulsifying activity is determined（EAI）And emulsion stability
（ESI）.From the figure 3, it may be seen that after treatment of different temperature, oils and fatss body emulsifying activity（EAI）Excursion is 59.97 ~ 69.61m2/
G, emulsion stability（ESI）Excursion is 71.20 ~ 110.48%, and variation tendency is steady.Illustrate the condition that different temperatures changes
Under, oils and fatss body has higher emulsion stability.
Specific embodiment two：Present embodiment is explained as follows to oils and fatss body application prepared by specific embodiment one：
1st, oils and fatss spray body is dried
Relatively enrich containing substantial amounts of higher unsaturated fatty acid, especially Oleic acid, linoleic content in soybean oil body.
But unsaturated fatty acid is susceptible to oxidation in soybean oil body, and reduces its nutritive value, while can also generate
Material, has undesirable effect to health.The micro encapsulation of soybean oil body can be effectively prevented from soybean oil body not
The oxidation deterioration of satisfied fatty acid, extends the storage phase of soybean oil body.
Micro-encapsulation technology flow process：Soybean oil precursor emulsion+wall material → constant temperature stirring → homogenizing → emulsion → spray dried
Dry → microcapsule finished product.
Weigh a certain amount of soybean protein isolate, maltodextrin（The proportioning of soybean protein isolate/maltodextrin is 1:1）It is molten
In entering 60 DEG C of warm water, mixed solution temperature is kept to be 60 DEG C（Heating in water bath）, stir 20 minutes.It is gently molten to mixing
Soybean oil precursor emulsion is added in liquid（40% used as optimal core addition）, continue to stir 10 minutes, under 30MPa
Homogenizing is carried out, it is 180 DEG C to be spray-dried intake air temperature, and air outlet temperature is 75 DEG C, and flow velocity is 900mL/h, in this condition
Under carry out spray drying treatment.
2nd, application of the oils and fatss body in peanut butter
Peanut butter is a kind of multiphase dispersion, and the content of wherein oils and fatss and solid content occupies very big ratio, and oils and fatss,
Solid content and water three are immiscible, and the proportion between their threes is also different, thus sauce body be easy to occur oil,
Water, the layering of beans three.And the effect of emulsifying agent is exactly the surface tension for reducing each liquid phase, make each mutual after dispersed
Between repulsion reduce, reach the effect of stable emulsifying.Therefore add suitable emulsifying agent the stability of peanut butter is played it is very big
Effect.
Oils and fatss body powder is a kind of good emulsifying agent, can both make w/o type, can also make O/W type emulsifying agents, is added to Semen arachidis hypogaeae
After beans, the sauce body granular absorption emulsifier molecules can be made so that the granule for colliding is non-condensing, thus be formed around solid content
Protecting film.
