Embodiment 1

[0019] A kind of tea seed oil containing steviol glycoside natural antioxidant and sweet taste is to add stevioside glycoside to the pressed tea seed oil, and the weight ratio of stevioside glycoside is: tea seed oil: steviol glycoside=100 : 0.6, made by mixing evenly.

[0020] The resulting product is tested after being stored for 18 months and shows no oxidative rancidity.

Embodiment 2

[0022] A sweet tea seed oil containing natural antioxidants of steviol glycosides is to add steviol glycoside (RA) to the squeezed tea seed oil, and the weight ratio of steviol glycosides is: tea seed oil: stevia Glycoside = 100:0.5, mixed evenly to prepare.

[0023] The resulting product is tested after being stored for 18 months and shows no oxidative rancidity.

Abstract

Sweet tea seed oil containing stevioside natural antioxidants is characterized in that stevioside is added into tea seed oil. The tea seed oil has the advantages that natural food sweetening agents-stevioside are applied to tea seed oil. The test proves that the antioxidation function of the stevioside is identical to chemical synthesis antioxidants-tertiary butylhydroquinone (TBHQ), and accordingly, the storage period of tea seed oil can be prolonged, the tea seed oil is harmless to human bodies, and the tea seed oil quality can be improved.

Description

technical field [0001] The invention relates to edible oil, in particular to tea seed oil containing steviol glycoside natural antioxidant and having sweet taste. Background technique [0002] The tea seed oil sold in the market today is edible oil obtained by pressing tea tree seeds, decolorizing, deodorizing, adding chemically synthesized antioxidants and other refining processes. It is known that tea seed oil contains more unsaturated fatty acids. Light-induced auto-oxidation under certain conditions will produce free radicals, hydroperoxides, small molecule aldehydes and ketones and other harmful substances, and the obvious feature is rancidity. Rancid tea seed oil, first, its nutritional value is greatly reduced, vitamin A, vitamin D, vitamin E (V A , V D , V E ) is first oxidized, long-term consumption of rancid tea seed oil leads to a series of symptoms due to the lack of essential fatty acids; second, the free radicals produced by rancidity can cause tumors by dam...
