ginger milk curd 薑汁撞奶

background:

ginger juice + milk protein --> curd

zingibain protease生姜凝乳酶 + casein酪蛋白 --> milk coagulant凝固

Ingredients:

old ginger 35g

高鈣低脂奶 (十字牌或維記或其他高蛋白質含量 >= 4 g per 100g)，重要是蛋白質成份高, 並非奶脂 . 鈣亦有助凝固.

糖 10g

Tool:

grate

thermometer

preparation:

grate ginger and make ginger juice. 12 g is needed

the ginger juice to milk is 1: 8 ( ie 12 g ginger juice to 100g milk)

add 10 g sugar to milk

use hot water bath to warm milk up to 70 deg C. Stir the milk to dissolve the sugar

Remove the milk from water bath, and let milk cool down to 60 deg C ( zingibain is most effective at 60 deg C)

If temperature is 70 deg C or higher, zingibain protease will be denatured.

pour ginger juice to bowl

pour milk at height of 20 to 30 cm above the bowl

don't stir the mixture! and let it rest for 20 min

CMOS sensor trends and astrophotography, from amateur astronomers perspective

Nowadays, even in low light conditions, digital camera can quality pictures with higher ISO, noise and hot pixels have been gradually reduced. Sony has introduced back illumination process for consumer market. Sony BSI sensors evolved from Exmor to now Exmor RS( stacked) technology. This stacked technology allows further chip size reduction, which has strong demands in smartphone camera market. Digital astrophotography is also benefited from such advances, utilising Back Side Illumination technology Exmor: Within the CMOS sensor, it outputs low-noise digital signals by "on-chip column AD conversion" and "dual noise reduction" to suppress noise in the first half of the process In low light conditions, when a wide aperture is desirable to collect as much light as possible. At apertures wider than f/2.0, back-illuminated Exmor R sensors are significantly more efficient at collecting light than conventional, front-illuminated sensor...

ultrafast rendezvous to ISS

14 Oct 2020, being the first to use a new “ultrafast” rendezvous” scheme with the ISS. Following a flawless ascent to the correct orbit, Soyuz 2 .1a , Soyuz MS-17 caught up with the orbiting laboratory in only two orbits (three hours), halving the time it takes for crew to get to the Station. The three space travelers of the Soyuz MS-17 mission launched on a six-month mission the International Space Station. previous 3/4 orbit rendezvous: Soyuz MS-16 4 orbit rendezvous A three-orbit profile was deemed possible without major flight design changes after inauguration of the Soyuz 2-1A rocket that provides a much higher orbit injection accuracy than its predecessors and would allow the two correction maneuvers on Orbit #2 to be eliminated while the Automated Rendezvous Phase would still remain untouched. The deletion of the Orbit #2 maneuvers was expected to slightly tighten the already restrictive phase angle window from and upper limit of 30-35° to 25-28°...
