The invention belongs to the technical field of
food processing, and particularly discloses a preparation method of peanut
protein-
chitosan-tea
polyphenol oleogel and application of the oleogel in
peanut butter, peanut
protein,
chitosan and tea
polyphenol are used as raw materials, an
emulsion template method is adopted for preparing the oleogel, firstly, a peanut
protein aqueous solution and a
chitosan acetic acid solution are mixed, and then the oleogel is prepared. Adding tea
polyphenol to form a composite solution, and freeze-
drying to obtain composite particles; the compound particles are prepared into dispersion liquid, the dispersion liquid and
peanut oil are homogenized according to a certain volume ratio of an
oil phase to a water phase to form an
emulsion template, the water phase is removed through pre-freezing and freeze-
drying, and the oleogel is obtained. The oleogel prepared by the invention has better oil holding capacity and rheological property and shows good soft
solid gel performance, and the oleogel is added into the
peanut butter according to a certain proportion, so that the
oil separation during the storage period can be reduced, and the increase of
acid value and
peroxide value can be slowed down, thereby improving the storage stability of the
peanut butter.
