Pectin: lub mob thiab kev pab. Daim ntawv thov thiab khoom ntawm pectin

Substance hu ua "pectin" twb faib thaum pib ntawm lub xyoo pua puv 19 Fabkis academician Anri Brakonno Science News for KIDS. Tus thawj yam khoom los ntawm qhov uas cov kws tshawb fawb tau txais qhov khoom, nws yog ib tug kua. Lub loj zus tau tej cov tshuaj yeeb dej caw twb tau txais nyob rau hauv 1930.

Pectin: zog thiab ntau lawm

Qhov no tshuaj yog ntawm tsob nroj keeb kwm. Nws tau ratchet zog. Ntawm tus taw tes ntawm view ntawm science, yog ib tug polysaccharide tau undergone pre-kev kho mob tau los ntawm lub extraction ntawm citrus thiab Kua sis plawv hniav. Cov zaub mov kev lag luam yog hu ua tus additive E440. Stabilizer muaj zog, gelling neeg sawv cev, thickener thiab clarifier. Nyob rau hauv tas li ntawd mus rau lub txiv hmab txiv ntoo, nyob rau hauv ib co zaub thiab paus cov qoob loo. Lub citrus heev theem siab ntawm ib yam khoom uas xws li pectin. Cov kev puas tsuaj thiab kev siv ntawm tej zaum nws yuav sib npaug. Hais txog qhov no - tom qab nyob rau hauv tsab xov xwm. pectin lawm yuav tsum tau kim heev thiab complex cov khoom. By thiab loj, zoo yam txiv hmab txiv ntoo muaj peev xwm tau muab rho tawm los ntawm extracting E440. Thaum tau txais daim ntawv ntawm pectin extract yog ua tib zoo ua los ntawm ib tug tshwj xeeb technology, thaum lub substance tsis tau tus tsim nyog zog.

Nyob rau hauv Russia, tagnrho E440 ntau lawm yog tseem ceeb. Pectin yog feem ntau rho tawm los ntawm apples thiab beets. Raws li statistics, nyob rau hauv lub xyoo nyob rau hauv Russia ua txog 30 tons ntawm cov tshuaj yeeb dej caw.

Muaj pes tsawg leeg ntawm pectin

Additive E440 yog heev nyob rau hauv Dietetics. 100 g ntawm cov khoom zog tus nqi tsis pub tshaj rau cov theem ntawm 55 calorie ntau ntau. Nyob rau hauv ib tug me nyuam diav ntawm - 4 cal.

Nws yog tsis muaj daim card uas feem ntau tsis tshua muaj-calorie polysaccharide pectin yog suav hais tias. Properties thiab nws tus nqi noj haus hais lus rau lawv tus kheej: 0 g roj thiab 0 g ntawm protein. Feem ntau ntawm cov neeg nyob hauv carbohydrates - mus txog rau 90%. Muaj pes tsawg leeg muaj xws li pectin tshauv, disaccharides, organic acids thiab dej. Tus so ntawm qhov feem pua ntawm coj kev noj haus fiber. Ntawm cov vitamins yuav tsum faib niacin sib npaug RR. Nrog kev hwm rau cov mineral Cheebtsam, lub pectin lawv abound: phosphorus, poov tshuaj, hlau, magnesium thiab calcium. Tshwj xeeb tshaj yog tseem ceeb cov tshuaj yeeb dej caw muab siab sodium cov ntsiab lus (mus txog 430 mg).

Cov kev pab cuam ntawm pectin

Muaj ntau cov kws txawj ntseeg tau hais tias lub E440 yog qhov zoo tshaj plaws organic tshuaj "ntxuav tu" ntawm tib neeg lub cev. Qhov tseeb hais tias pectin, kev puas tsuaj thiab kev siv cov uas txhua tus txiv neej nyob rau hauv txoj kev muaj nqis txawv, qhia ntawm fabrics teeb meem microelements thiab tej yam ntuj tso tshuaj lom, xws li tshuaj tua kab, tej ntsiab, hnyav hlau , thiab lwm yam Nyob rau hauv cov ntaub ntawv no, lub bacteriological tom qab ntawm lub cev yog tsis ntxhov.

Tsis tas li ntawd ib tug ntawm qhov zoo tshaj plaws regulators ntawm oxidative kev ntawm lub plab yog suav hais tias yog pectin. Kev siv cov no yam khoom uas yuav mus normalize metabolism. Nws tsuas tsis pab txoj kev ncig thiab plob tsis so tswj, tab sis kuj ho thiaj li qib roj uas txhaws taus. Pectin yog ib tug soluble fiber tej zaum yuav hais, raws li nws xyaum tsis phua thiab tsis absorbed nyob rau hauv lub digestive system. Dhau los ntawm lub hnyuv nrog rau lwm cov khoom, E440 absorbs cholesterol thiab lwm yam teeb meem hais, hnyav tso zis ntawm lawv lub cev. Tsis tas li ntawd, pectin muaj peev xwm sawv ntawm losis tswvyim dabtsi ions ntawm hnyav hlau thiab tej, normalizing cov kev thiab kev ua si ntawm lub plab.

Lwm zoo dua ntawm cov khoom yog hais tias nws pab txoj kev zuag qhia tag nrho plab hnyuv microflora, anti-inflammatory nyhuv rau lub plab hnyuv mucosa. Pectin yog pom zoo rau peptic rwj kab mob thiab dysbiosis.

Puas tsuaj los ntawm pectin

Additive E440 muaj zoo tsis muaj yam tsis zoo tshwm. Nws yog to taub hais tias nws yog tsis zoo yaim los ntawm lub substance (mloog zoo, pectin). Raug mob thiab cov kev pab los ntawm nws - ib tug zoo kab, sawv rau cov uas, lub txim yuav tsis muaj ntev tos. Nrog ib tug overdose ntawm pectin tshwm sim ntau npaum li cas flatulence tshwm sim los ntawm ib tug tsis txaus ntawm plab hnyuv microflora. Tsis tas li ntawd, ntau kev siv ntawm lub lim additives los yog tshuaj nrog ib tug high school cov ntsiab lus ntawm cov khoom no yuav ua rau raws plab, tu-sauv nrog mob. Nyob rau hauv overdose pectin tiv thaiv qhov haum rau hauv cov ntshav minerals xws li magnesium, zinc, hlau thiab poov hlau. Tsis zoo digested thiab proteins.

Ib tug zoo xws li cov nyhuv sab ua ke nrog ib daim tawv nqaij sawv pob tej zaum yuav tshwm sim thiab yog hypersensitive polysaccharide.

Kev siv ntawm pectin

Nyob rau hauv xyoo tsis ntev los, lub tshuaj yog thoob plaws nyob rau hauv lub chaw ua tshuaj thiab khoom noj khoom haus industries. Nyob rau hauv cov kev kho mob kev lag luam nws yog siv los muab ib tug physiologically active tshuaj. Cov tshuaj muaj ntau pab tau rau cov tib neeg lub zog. Ua kws tuam txhab uas muag siv rau qhov siv thiab ua tsiav tshuaj noj tshuaj xwb pectin.

Daim ntaub ntawv nyob rau hauv cov zaub mov cheeb tsam no yog nqa tawm raws li tej yam ntuj tso additives thiab thickener. Pectin yog feem ntau siv nyob rau hauv qhov siv thiab ua jelly, marshmallow, jelly, ice cream thiab ib co khoom qab zib. Tam sim no, ob hom yog distinguished tshuaj: cov hmoov thiab kua. Lub particulate daim ntawv no yog siv nyob rau hauv qhov siv thiab ua pectin jelly marmalade. Kua polysaccharide yog ntxiv rau cov kub loj yog ces poured rau hauv cov ntaub ntawv.

Khoom noj muaj ib theem siab ntawm pectin

Cov tshuaj yeeb dej caw yuav tsuas yuav tau los ntawm txiv hmab txiv ntoo, berries los yog zaub. Additive E440 yog ib tug natural khoom, yog li nws yuav tsum tau ua heev dua lwm yam los ntawm cov nroj tsuag. Raws li peb paub, ib yam khoom uas xws li pectin, raug mob thiab cov kev pab - lo lus nug yog lom zem ntau ib tug nkag siab ntawm kev faib ua feem. Yog li ntawd nws yog tsim nyog los paub nyob rau hauv dab tsi cov khoom nws saum toj no cov ntsiab lus mus tom qab sib txawv tagnrho ntawm tau.

Feem ntau cov pectin pom nyob rau hauv cov txiv kab ntxwv, beets, txiv qaub, apples, apricots, zaub qhwv, txiv ntoo qab zib, tag, dib, qos yaj ywm, carrots, txiv duaj, txiv kab ntxwv soob, pear thiab ib co berries, xws li cranberries, gooseberries thiab currants.
