聞起來和吃起來味道都很臊的「臊豬肉」是怎麼回事？是不是有的人吃的出臊豬肉有的人吃不出？

01-13

就我身邊的經歷我和我媽還有我妹對這個豬肉的味道特別敏感基本大老遠就能聞出來但是我爸爸就吃不出來然後我各個姨夫舅舅也吃不出來貌似女性對臊豬肉的敏感程度較高？

From wikipedia

Boar taint is the offensive odour or taste that can be evident during the cooking or eating of pork or pork products derived from non-castrated male pigs once they reach puberty. It is only found in a small minority of pigs and can be found in both males and females as the chemicals that cause the smell are produced in the intestines as well as the testes.

Studies show that about 75% of consumers are sensitive to boar taint so it is necessary for pork producers to control it.

異味主要存在沒閹割的成熟公豬里，所以又叫公豬異味。只有一小部分豬會有這種異味，而且其實公豬母豬都會有這種異味，因為腸子和睾丸都能產生異味物質。

Women appear to be more sensitive than men and some ethnic groups also seem to be more sensitive than others.

About 25% of consumers cannot detect the taint chemicals and about 80% of boar pigs do not have taint. Selecting pigs for breeding that do not have taint and managing on pasture virtually eliminate any chance of boar taint and have been successfully used at many farms.

女性似乎對這種異味更敏感。大約25%的人對此不敏感，80%的公豬沒有這種異味。

Causes

Boar taint is caused by the accumulation of two compounds – androstenone and skatole – in the fat of a minor number of male pigs. Most pigs do not have boar taint and it is rare by slaughter weight age.

公豬異味是由兩種化合物雄酮和糞臭素在公豬的脂肪中蓄積形成的。

Androstenone (a male pheromone) is produced in the testes as male pigs reach puberty, while skatole (a byproduct of intestinal bacteria, or bacterial metabolite of the amino acid tryptophan) is produced in both male and female pigs. However levels are much higher in intact boars because testicular steroids inhibit its breakdown by the liver. As a result, skatole accumulates in the fat of male pigs as they mature.

雄酮（一種雄性信息素）在雄性豬只性成熟時在睾丸內產生，而糞臭素（腸道菌的副產物，或是色氨酸的細菌代謝產物）在雄性和雌性豬只體內都會產生。但是，未去勢公豬體內糞臭素的水平要高得多，這是因為睾丸激素抑制了肝臟對其的降解。於是，糞臭素便在雄性豬只成熟過程中在它們的脂肪中累積起來。

這些化合物在雄性豬只性成熟時自然產生，如果任其長時間在公豬體內積累，當豬只被宰殺烹食時，由它們引起的異味很難讓人忽略。為了防止這些化合物的蓄積，生豬生產者通常將仔公豬去勢。

你說的這個應該是未經閹割的公豬

豬肉味道已不是兒時的記憶，主要在於飼養方式不同：以前農戶家的豬吃野菜，散養的豬，肉質香嫩！現在能買到的豬肉一般是飼料，養殖廠里統一飼養的，所以會有膻味。每個人對味道敏感度不同，並無性別差異。
