Abstract: Cheese that shows a suppressed decrease in texture and/or stretchability of cheese due to heating, may be produced by allowing glucose oxidase, ?-glucosidase, transglutaminase, or a combination of such enzymes to act on raw cheese. Cheese analogues improved in meltability and/or stretchability during heating, may be produced by allowing ?-glucosidase to act on a mixture containing plant-derived oil and starch, or starch before mixing with plant-derived oil.

Abstract: An image display apparatus according to an embodiment of the present technology includes a polarizer, a polarization conversion element, and a ¼ wave plate. The polarizer causes to transmit linearly polarized light having a predetermined polarization direction. The polarization conversion element converts a polarization state of the linearly polarized light transmitted through the polarizer and emits the light as light in a non-polarized state. The ¼ wave plate is arranged on an optical path of the light in the non-polarized state emitted from the polarization conversion element.

Abstract: An improvement in quality is achieved by improving a contrast ratio. Therefore, in a projector device including a light source device using a solid-state light source (AR) includes a temperature adjustment device (190) capable of setting a state in which a temperature of at least the solid-state light source is caused to increase. Then, a determination unit (12) determines a luminance state of an image and a control unit (16) controls a heat state of the solid-state light source (AR) by controlling the temperature adjustment device (190) on the basis of a determination result. In particular, by increasing the temperature of the solid-state light source (AR) in accordance with an image, light emission efficiency is lowered to decrease luminance.

Abstract: An image display apparatus according to an embodiment of the present technology includes: a light emission unit; and a polarization conversion element. The light emission unit emits image light. The polarization conversion element has an incident surface, converts a polarization state of the image light that enters the incident surface, emits the converted light as image light in an unpolarized state, and is configured such that conversion properties of the polarization state are non-uniform in the incident surface. As a result, it is possible to sufficiently depolarize the image light and display a high-quality image. In addition, it is possible to reduce uneven polarization and speckles.
