In 2014, Cho Hyun-e, the chairman of Korean Air, made a big fuss on the plane and returned to the flight, simply because the macadamia nuts given to her by the flight attendant were not peeled. Before this "nut return" storm, Koreans were not cold to macadamia nuts. The headlines sparked a surge in sales of macadamia nuts in South Korea.
This nut will not only cause a storm, but also produce a oolong. Like what:
The home of the macadamia nut is not Hawaii, USA, but in Australia;
The country with the largest production in the world is neither Australia nor the United States Hawaii, but China;
Is that neat slit in the hard shell of each macadamia nut cut out?
Macadamia nuts, of the family Diplodocus Macadamia nuts are the fruit of tall trees. Native to Queensland, Australia, it is officially known as macadamia nuts and is alias Queensland chestnut.
The fruit is spherical, the outer peel is green, and browns when dried. After removing the outer skin, the inner peel is a hard shell, and the kernel is milky white and belongs to the nut class. The shelled fruit resembles a small ball of volcanic ash condensation, also known as volcanic beans.
Macadamias were not taken seriously in the country of origin before 1858 and were completely self-reliant. The local natives considered it to be highly toxic and ate it after repeated treatment.
Walter Hill, director of the Botanical Gardens in Brisbane, Australia, and others discovered it and named it after a friend, Macadamia.
Hill hired a boy to help him knock nuts, who knew that the boy was curious and risked death to eat the nuts. The ending is the same as the tomato, and the boy is not only unharmed, but also said to be particularly delicious. After that, there is one more high-grade nut in the world.
It was introduced to Hawaii in 1881 as an ornamental and storm-proof plant. Who knew that American foodies suddenly fell in love with its deliciousness and began to process and sell. However, consumers across the United States only know that it is from Hawaii, which gives birth to the name of macadamia nut. It was formally planted commercially in 1921 and has been going on for a hundred years.
Macadamias originated in Australia and were not widely cultivated commercially until after the 1960s. The fruit tree enters a high-yield period of about 6 years, and its life expectancy can reach more than 80 years. Because it is drought-tolerant and waterlogging-tolerant, it is rarely cared for, and it can be called a lazy cash cow.
It was also Hill's little helper who was lucky, and the one he ate was non-toxic. There are 10 species of macadamia nuts in the local area, and only 2 species are non-toxic and edible, namely light shell species and coarse shell species. Other species do contain cyanosides to some extent, which is potentially toxic. The non-toxic light-shell species are of the best quality, and hundreds of excellent cultivars have been bred based on this mother, which are thinner than the large shells of wild varieties.
However, any variety of macadamia nuts, no, macadamia nuts, is toxic to dogs. If they eat a little more, they will be weak on all fours, paralyzed, and even dead. However, the poisonous varieties are also evergreen trees with a delicate tree shape, which can be used as a good ornamental tree species for greening.
The 8th International Macadamia Congress in 2018 was held in Lincang, Yunnan.
It was only after 1979 that the introduction of macadamia nuts began Chinese mainland. Wang Zhengguo, an 80-year-old director of the Yunnan Institute of Tropical Crops Sciences, has developed a single variety to hundreds of varieties since 1981, and has won the international lifetime achievement award in this field. At present, China is already the world's largest producer of macadamia nuts, yunnan province alone accounts for 57% of the world's total planting area, and the output is also more than the total foreign countries.
Yongde County and Zhenkang County in Lincang City, Yunnan Province were introduced earlier. Yingjiang County in Dehong Prefecture has also developed rapidly, becoming the largest macadamia planting base in Asia. It has now been extended to Pu'er, Banna, Baoshan, Honghe and other areas.
In addition to Yunnan, guangdong, Guangxi and Hainan are also partially cultivated. Among them, Guangxi Chongzuo Fusui County was rated as "Macadamia Standardized Production Park" by the Ministry of Agriculture in 2013.
Macadamia nuts are at least $40 per kilogram. The yield has increased greatly, why is it still so expensive?
Macadamia nuts have a saying of "a thousand flowers and one fruit", each tree can produce about 10,000 inflorescences at a flowering period, and each inflorescence has about 300 small flowers, but in the end only one-thousandth to four-thousandths of flowers can set fruit.
Then there is the fact that fruit processing is also very laborious.
The bigger reason is that it's so delicious, it's in high demand, and it's enough to increase the total production of the world by more than 8 times! As a result, the price does not come down in the short term.
King of nuts
Macadamias are considered one of the best nuts in the world. The nuts are crispy and smooth, with a unique creamy aroma, and the flavor and texture are more than cashew nuts, etc., and are known as the "King of Nuts in the World" or "Queen of Dried Fruits".
In addition to being eaten directly as a snack, macadamia nuts can also be used to make confectionery, bread, candy, chocolate, etc., or as a topping for dishes.
Macadamia nuts contain 60 to 80% of the oil, 9% of the protein, eat it can also supplement some calcium, iron, zinc, selenium and other minerals and folic acid, riboflavin and other vitamins.
Its oils and fats are similar to olive oil and tea oil, and the main fatty acid is oleic acid, which is a monounsaturated fatty acid. Eating often is beneficial to regulate blood lipids and reduce the incidence of cardiovascular and cerebrovascular diseases and diabetes.
Its oil is clear and transparent, smells fragrant, and is a high-grade natural salad oil. It can also replace dairy products to make ice cream, which is suitable for lactose intolerants.
Macadamia oil is widely used by major international brands to make high-end cosmetics.
Macadamia nuts are produced in China and are fully ripe around the Time of September Bailu Festival.
The market is full of processed and fried products, mainly original, salt baked, creamy, and other flavors such as mustard and basil can be bought in some places. I personally think that the original taste is not as good as the taste with flavors and flavors, but it is healthier and more durable.
Macadamia nuts are delicious, which does not mean that you can eat them with an open belly, after all, the oil content is high and it is easy to fatten.
Its shell is far harder than a walnut and is a veritable nut. Only certain parrots and rats in nature can open, and human teeth are not up to it. But we'll invent tools, and when we buy macadamia nuts, we'll send the simplest fruit opener. There is really no fruit opener, but it takes a little more effort to find a small hammer.
There is a neat slit in the hard shell of each macadamia nut, and some people do not hesitate to say that it is cut by hand.
In fact, this gap is naturally cracked when it is ripe. However, the original gap cannot be very neat, and the natural gap is squeezed and flattened by the machine later.
The general opening accounts for about 60% of a circle. There are also more than 80% of large openings.
