Hana hana o ka monosodium glutamate

Nā hana hana o ka monosodium glutamate : hydrolysis, fermentation, synthesis a me ka unuhi.

1. Hydrolysis

Kumu: Ua hoʻoheheʻe ʻia ka mea protein maka e ka waikawa e hana ai i ka glutamic acid, a ua hoʻohana ʻia ka glutamic acid hydrochloride.

Loaʻa iā ia ka haʻahaʻa haʻahaʻa loa i ka waika hydrochloric. Hoʻokaʻawale ʻia ka ʻakika Glutamic a lawe ʻia, a laila

Hoʻomākaukau ʻia ka monosodium glutamate e ka mālama neutralization.

ʻO nā mea kanu protein maʻamau i ka hana ʻana - gluten, soybean, kulina, etc.

ʻO ka hoʻoheheʻe ʻana i ka hydrolysis

ʻO ka meaʻai maka protein - glutamic acid - monosodium glutamate

2. Hoʻopalapala

Kumu:

Hoʻohana ʻia nā mea maka starchy e hana i ka glucose, a i ʻole hoʻohana pono ʻia ka molasses a i ʻole ka acetic acid

ʻO nā mea waiwai: ʻo ka glutamic acid ka biosynthetically synthesized e ka glutamic acid e hana ana i ka bacteria, a laila hoʻokaʻawale ʻia a unuhi ʻia.

Hana iā MSG.

Mākaʻikaʻi maka – → ka waiʻona kō – → glutamic acid fermentation – → neutralization – → monosodium glutamate

3. ʻO ke ʻano hana synthetic

Kumu: ua hoʻokahe ʻia ka propylene e hoʻoheheʻe ai i ka ʻaila ʻaila a hoʻoulu ʻia e hana i ka acrylonitrile.

ʻO ka cyanidation, hydrolysis a me nā hopena ʻē aʻe e hana i ka racemic glutamic acid, a laila hoʻokaʻawale ʻia i L-glutamic acid,

A laila hana ʻia i monosodium glutamate.

Propylene → oxidation a me ka ammoniation → acrylonitrile → glutamic acid → monosodium glutamate

4. Keʻano unuhi

Kumu: E lawe i ka molasses ʻōpala i mea maka, e hoʻihoʻi mua i ka sucrose i loko o nā molasses ʻōpala, a laila hana hou i ka wai ʻōpala.

Ua hoʻomākaukau ʻia ka monosodium glutamate ma ka hydrolyzing a me ka hoʻopaʻa ʻana me ke ʻano alkali, ka unuhi ʻana i ka glutamic acid, a laila hoʻomākaukau i ka monosodium glutamate.

ʻO ka hydrolysis, ka hoʻohaʻahaʻa ʻana, ka ʻohi ʻana

Molasses ʻōpala — → glutamic acid — → monosodium glutamate
