Is the mould constant evil and unforgiving? 


But it involves really looking at the type of mould.

Let's have the colored glasses put down first, and after the text is read below, you may understand more? 




The protein in the papaya is so high, so it's so easy to get black, but the time is right, and it's the best time to eat!  In above pictures, the mould was found in a day in the second photo.

My personal learning, is about my father-in-law's teachings…

"Yin-Yang Equilibrium" is the essence of everything.

Bacterial and sterile, good image is eternal and consistent, and good image is not?

Yes, we have the talent: we have the ability to use beneficial bacteria, so we have a comparatively effective immune system.

Our intestinal tract has a large amount of bacteria, the ability to produce enzymes, the ability to produce them, and the ability to fight against harmful bacteria.

There is also a law, as long as we have food, the demand will be met, we will have a small amount of bacteria, and the talent will help us have immunity.

In science, one of the milestones of research is "true science related to the origin,'' one of which is a doctoral course in science.

Food industry has established a fermentation process for fermentation products “Color, aroma, taste'' in our soya bean sauce, Koji mold is purchased by the factory and provided with Aspergillus for fermentation. However, the toxicity of aspergillus will be result if improper use for human, and the truth is difficult to define!

However, whether edible food or not, you should consider the freshness of the food, if it is as good as it is, it will be left more than one month, it will be possible to eliminate bacteria, and it is possible to have a large amount of bacteria.

Aspergillus is a beneficial food, among others
1. Shibashi
2. Salami sausage
3. Taiwanese red yeast rice
4. The most beneficial ingredient in china, which has been studied in scientific research, comes from the herbaceous fungus.


Antibiotics – ready for production of Nishilin, also by a Penicillium moulds, a scientist was unable to synthesize large quantities of antibiotics in World War II, unexpectedly, One day, researcher Mary Hunt, a woman in Peoria, Illinois, USA, discovered that the skin of a moldy cantaloupe was covered with penicillium. She used this cantaloupe to screen out a strain that could secrete large amounts of penicillin, and its penicillin production could reach 250 units per ml.



Basically, we can’t see it with the naked eye. What we eat can no longer be separated from “sterile”. This is bean curd, pickles, natto, tempeh, Kimchi, soy sauce, even tangerine peel and aged Pu’er. and the now very popular Indonesian bean cake (tempeh, called tokwa in the Philippines)

Molds are beneficial foods:


1. cheese
2. Italian Salami
3. Red yeast rice, a health food for Taiwanese and northerners
4. Some Chinese medicines, such as Gastrodia elata and Cordyceps, scientific research has found that their most beneficial ingredients are mold.

Antibiotic-penicillin is also produced by Penicillium.

However, be careful when the following foods become moldy:

1. There has been a serious incident of apple juice poisoning because the juice contains a toxic substance called patulin.
2. Sticky skin on melons means not only mold but also infection by harmful bacteria
3. Moldy nuts may contain Aspergillus aflatoxin

Report by Ms. Ma Ka Ming, Scientific Director

Generally speaking, toxin-producing molds are mainly found in cereals and beef crops.

As for whether moldy or rotten food can be eaten or not, I believe there is still controversy1

科學上,參考港台一個節目「原來真係好科學」,其中一個科學博士所講,發霉,和食物發酵,其實是同一個Process – fermentation (食物變質),又算不算上變壞?






1. 芝士
2. 意大利沙樂美腸
3. 台灣和北方人的保健食品紅麴米
4. 部份中藥例如天麻以及蟲草,科學研究出他們的最有益成分原來是霉菌。


抗生素-即為盤尼西林,也是由青黴菌所製造,當年科學家無法大量生產合成,意外地,在一個家中嚴重發霉的哈密瓜大量地發現,因此才能夠將抗生素大量生產。一日,研究人員瑪莉·亨特(Mary Hunt)女士在伊利諾州的皮奧里亞市場發現一顆發霉的哈密瓜表皮長滿青黴,她用這顆哈密瓜篩選出能大量分泌青黴素的菌株,其青黴素產量可達每毫升250單位。


基本上我們只是肉眼看不到,我哋所吃的東西已不能和"無菌"分開,這個是豆腐 (bean curd)、梅菜、納豆、豆豉、Kimchi、豉油甚至陳皮以及陳年普洱和現在很流行受到追捧的的印尼豆餅 (tempeh, 菲律賓叫 tokwa)
