The end of the year is approaching, nuts are a must-have for every family's New Year's goods, so how to judge the quality of macadamia nuts?Shelf life and freshness
Check the manufacturing date and expiration date on the packaging to make sure you are buying within the expiration date. Fresh macadamia nuts are usually uniformly dark brown or light brown in color, rather than dark black or off-white, indicating that the fruit is not over-oxidized or damp. 
Appearance
Shell: The shell of a good quality macadamia nut should be smooth and crack-free and hard, bright in color, and free of mold or other impurities. Nut size: Larger macadamia nuts tend to have a longer growth cycle, full kernels, and a better taste. When picking, choose nuts with a rounded overall outline and uniform size. After shelling, the color of the flesh is preferably milky white or light yellow, if the flesh is too dark or even dark brown, it may have deteriorated. 
Taste
There are a variety of flavors on the market, such as plain, creamy, and salt-baked, so you can choose according to your personal preference. A good quality macadamia nut should have a strong natural aroma, especially a creamy variety, which has a mellow but not greasy taste. 
Opening case
Commercially available macadamia nuts are usually treated with openings so that consumers can open them, through which the flesh of the fruit can be seen inside, and the flesh of a good macadamia nut should be intact and not chipped, moldy, or spilled oil. Palate
A good quality macadamia nut should taste crispy and delicious, with a unique natural milky flavor that is not bitter or oily. Have you learned?
