Embodiment Construction

[0023] An intelligent gas-phase antioxidant film containing rosemary thermosensitive liposomes, which is prepared by the following method:

[0024] S1. To prepare rosemary thermosensitive liposomes, dipalmitoylphosphatidylcholine (DPPC, Shanghai Aladdin Biochemical Technology Co., Ltd.) 100mg, cholesterol (CH, biochemical reagents, Sinopharm Chemical Reagent Co., Ltd.) 20mg and Rosemary essential oil (REO, reagent grade, American ChromaDex company) 10mg was dissolved in 7.8L ether (anhydrous ether, analytical grade, Sinopharm Chemical Reagent Co., Ltd.) to obtain mixed solution 1, and the mixed solution was mixed under stirring conditions Add PBS dropwise to 100ml of PBS buffer solution at 30°C, and continue to stir for 30 minutes after the dropwise addition to obtain mixed solution 2; transfer mixed solution 2 to a round-bottomed flask, and use a rotary evaporator to remove diethyl ether to obtain the mixed solution three, and the mixed solution three was ultrasonically passe...

Abstract

The invention provides an intelligent gas-phase anti-oxidation film containing rosemary temperature-sensitive lipidosome and a preparation method thereof, and can solve the technical problem that the practical application effect is poor due to the fact that an existing anti-oxidation active packaging film cannot have the characteristics of long-acting effect and temperature sensitivity at the same time. The intelligent gas-phase antioxidant film containing rosemary temperature-sensitive lipidosome is characterized in that the film contains a rosemary temperature-sensitive lipidosome, the rosemary temperature-sensitive lipidosome is prepared from the following raw materials: dipalmitoyl phosphatidylcholine, cholesterol and rosemary essential oil, and the mass ratio of the dipalmitoyl phosphatidylcholine to the cholesterol to the rosemary essential oil is 10: 2: 1. The intelligent gas-phase antioxidant film has an obvious slow release effect, the DPPH free radical scavenging rate reaches 47.3% within 720 h, meanwhile, the film has an obvious temperature sensitive characteristic, and two obvious endothermic peaks exist at the temperatures of about 38.5 DEG C and 41.8 DEG C.

Description

technical field [0001] The invention belongs to the technical field of packaging films, and in particular relates to an intelligent gas-phase anti-oxidation film containing rosemary temperature-sensitive liposomes and a preparation method thereof. Background technique [0002] Oxidative rancidity is an important factor affecting food spoilage. In recent years, antioxidant active packaging films have been more and more researched because they can effectively release antioxidants and protect the quality of food inside the package. However, the existing antioxidant active packaging films cannot have long-term effects And temperature sensitive characteristics, the practical application effect is poor. Contents of the invention [0003] The invention provides an intelligent vapor-phase anti-oxidation film containing rosemary temperature-sensitive liposomes and a preparation method thereof, which can solve the problem that existing anti-oxidation active packaging films cannot h...
