Abstract: The present invention belongs to the technical field of nanofiber emulsion, in particular to application of nanofiber emulsion to preparation of baked food. The nanofiber emulsion is nanofiber emulsion of a pomelo peel sponge layer, and is PCNF emulsion obtained by emulsification of a nanofiber emulsion stabilizer of the pomelo peel sponge layer and an oil phase; the amount of the nanofiber emulsion in the baked food is 18-90%, and the nanofiber emulsion replaces oil in traditional baked food; when the PCNF emulsion is added to the batter, bubble density of the batter is larger, and proper addition of the PCNF emulsion can reduce specific gravity of the batter, improve aeratability of the batter with soybean oil, reduce a baking loss rate and water activity, and prolong the shelf life of the cakes with the PCNF emulsion; hardness and chewiness of the cakes can be reduced.

Abstract: Provided in the disclosure are a display apparatus and a sound processing method thereof. The method includes: obtaining a control instruction for outputting an audio signal; in response to the control instruction, detecting a current audio output mode, the audio output mode including a normal mode and/or a low-latency mode; receiving audio data from a first external device in connection with the display apparatus via an external device interface, where a data format of the audio data is determined according to the audio output mode; based on that the audio output mode is the low-latency mode, performing a first type of sound effect processing on the audio data; and based on that the audio output mode is the normal mode, performing a second type of sound effect processing on the audio data.

Abstract: The disclosure provides a display apparatus and a method. The display apparatus includes a display, a communicator, an external device interface, a memory and a processor. The processor is configured for: receiving a command for adjusting an audio state of an external audio output device in connection with the display apparatus; determining a target audio state to which the external audio output device needs to be adjusted by parsing the command; sending, to the external audio output device, an audio state adjusting instruction for adjusting the audio state to adjust a current audio state of the external audio output device to the target audio state and an instruction for requesting audio state to request the external audio output device to send the target audio state to the display apparatus; receiving the target audio state returned from the external audio output device and displaying the target audio state.
