Kev puas tsuaj ntawm creamyroj

Txawm hais tias muaj cov ntsiab lus ntawm cov vitamins thiab microelements, peb yuav tsum nco ntsoov: roj yog cov calorie ntau ntau (748 kcal ib 100 grams) thiab cov khoom rog. Feem ntau cov neeg siv nws nrog rau cov khob cij thiab hmoov nplej, uas tsuas yog nce cov calorie ntsiab lus ntawm feem. Nrog kev ceev faj, nws yuav tsum tau noj los ntawm cov neeg uas muaj atherosclerosis ntawm cov hlab ntsha thiab rog rog. Txhawm rau kom tau txais txiaj ntsig kev noj qab haus huv ntau tshaj plaws, cov khoom raug pom zoo kom noj me me: 15-30 grams tauj ib hnub yuav txaus.

Nws yuav tsum tau muab sau tseg tias kev mob ntawm butter tseem tsis tau muaj pov thawj tshawb fawb, yog li nws tsis tas yuav tsum tso tseg nws txoj kev siv. Txhua yam yuav tsum nyob rau hauv moderation. Tsis tas li ntawd, cov roj siv yuav tsum yog cov khoom zoo, tsis muaj teeb meem additives thiab preservatives. Koj yuav tsum paub qhov txawv cov roj zoo ntawm cov khoom tsis zoo.

qauv qauv

Raws li txhua yam khoom noj khoom haus, muaj tsoomfwv cov qauv uas tswj hwm qhov zoo, kev nyab xeeb thiab tsim cov butter. Nyob rau hauv Russia, kev tsim cov khoom yog tswj los ntawm GOST 32261-2013. Tus qauv yog tsim los ntawm GNU VNIIMS ntawm Lavxias teb sab Agricultural Academy thiab tau txais los ntawm Council for Standardization, Metrology thiab Certification thaum lub Kaum Ib Hlis 14, 2013. Raws li GOST 32261-2013, kev tswj cov khoom zoo yog ua los ntawm kev siv cov ntsuas hauv qab no:

1. Organoleptic zog - saj, tsw, kev ntxhib los mos thiab tsos (xws li ntim thiab daim ntawv lo yuav tsum).
2. Resistant rau ntau yam kub.
3. Tshuaj ntsuas - cov ntsiab lus ntawm rog, noo noo, ntsev (NaCl), dyes, thiab lwm yam.
4. Cov ntsiab lus thiab qhov sib piv ntawm fatty acids.
5. Kev ntsuas ntawm microbiological ntsuas.

Lub xeev tus qauv tseem muaj cov txheej txheem los saib xyuas cov ntsuas no thiab cov cai rau kev lees txais cov khoom. Kev taw qhia tau muab hais txog lub neej txee, kev xa khoom thiab kev cia khoom.

Kev txiav txim siab ceev - ib qho kev qhia ua haujlwm

Kom paub tseeb tias qhov khoom zoo, ntsuas qhov ntom ntawm butter koj tus kheej. Qhov no yog ib qho txuj ci tseem ceeb heev, vim tias qhov ntsuas no suav tias yog tus yam ntxwv tseem ceeb tshaj plaws. Yog li, yuav ua li cas txiav txim siab qhov ntom ntawm butter hauv tsev? Peb yuav xav tau: ib daim butter, nplai, ib lub tais, lub khob ntsuas, ib tug kav thiab microwave (lub qhov cub hluav taws xob):

• Kev txiav txim siab qhov loj ntawm cov khoom. Ua li no, koj tuaj yeem siv cov nplais hauv chav ua noj ib txwm lossis tso siab rau cov cim ntawm cov khoom lag luam.
• txhawm rau txiav txim siab qhov ntim, koj tuaj yeem ntsuas qhov ntev, qhov siab thiab qhov dav ntawm ib lub pas ntawm butter, tab sis cov ntaub ntawv yuav txhim khu kev qha ntau dua yog tias cov khoom tau yaj tag. Koj tuaj yeem ua qhov no nrog lub qhov cub microwave. Nyob rau hauv tsis muaj nws, yaj lub butter nyob rau hauv ib tug da dej. Cov txheej txheem yog ceev heev, raws li lub melting point yog 28-35 degrees Celsius. Siv lub khob ntsuas ntsuas cov roj.

Nrhiav qhov ntom ntawm cov mis: P=M / V, qhov P yog qhov ntom ntawm butter; M yog qhov loj ntawm cov khoom; V yog nws qhov ntim. Chav ntsuas yog kg/m³ los yog g/cm^3.

Raws li cov qauv, qhov ceev yuav tsum yog 0.91 g / cm3.

Mass feem ntawm rog

Nws yog ib qho tseem ceeb kom paub tias dab tsi txiav txim siab qhov ntom ntawm butter, vim tias nws yog cov ntaub ntawv no uas qhia txog qib ntawm naturalness ntawm cov khoom. Qhov tseem ceeb tshaj plaws yog qhov zoo ntawm cov khoom siv raw, qhov siab dua nws qhov loj feem ntawm cov roj (MJ), qis dua qhov ntom ntawm butter. Cov roj no muaj txiaj ntsig zoo thiab noj qab nyob zoo.

Cov ntsuas ntsuas tau zoo sib xws thiab sib cuam tshuam. Feem ntau, ib lub chaw tsim tshuaj paus qhia txog cov roj cov ntsiab lus ntawm lub ntim. MJ tau txiav txim siab raws li cov lus qhia ntawm GOST 5867-90. Qhov ntom ntawm butter yog ib qho tseem ceeb qhia thaum xaiv cov khoom. Hmoov tsis zoo, cov ntaub ntawv ntawm lub pob tsis yog ib txwm muaj tseeb, thiab nws tseem ceeb heev uas koj tuaj yeem ntsuas koj tus kheej. Tsis txhob hnov qab tias tsuas yog cov roj tshiab thiab cov khoom muaj txiaj ntsig zoo rau kev noj qab haus huv.
