Ndokwa usoro iwu: kedu ka nd? ?ch?ch? ?wa si ak?wa polyglucose? ;

Otu mba ?wa na ?kp?r? nchekwa nri nke mba na-ewep? polyglucose n'?z? doro anya na udi nke "sugar" ma nye ya ?n?d? iwu nke eriri nri.

Polyglucose nke “Nri Safety National Standard Food Additive” (GB 25541-2024) na-emesi ike:

Polyglucose b? eriri nri na-edozi mmiri na enwegh? ike ikewa ya d? ka carbohydrate.

Mkpebi sayens?: Mba. The metabolite nke polyglucose b? SCFA kama glucose, na GI nke ya uru b? 0. A Clinical ikpe na Peking Union Medical College Hospital maka ?r?a mam?r? ?r?a gosiri na mgbe oriri kwa ?b?ch? nke 15g nke polyglucose maka 12 consecutive izu, ? d?gh? mgbanwe d? ?r?ba ama na hemoglobin a1c (HbA1c) nke ?r?a shuga 2 (3,Chinese).

2. Esemokwu 2: polyglucose ? b? "shuga agbakwunyere"? ;

Nk?wa nk?wa: D? ka ntuziaka WHO si kwuo, "shuga agbakwunyere" p?tara monosaccharides ma ? b? disaccharides (d?ka shuga, sucrose) na-etinye aka na nri. A nagh? ele polyglucose anya d? ka shuga agbakwunyere n'ihi na ? nwegh? kem?kal? na metabolic Njirimara nke shuga.

Na European Union na United States, a na-ag? polyglucose d? ka mkpok?ta eriri nri nke nri, kar?a "sugar"; Iwu izugbe nke China maka ?kp? aha nri akwadoro nri (GB 28050-2024) nakweere iwu a.

Ntuziaka nd? ah?a: Kedu otu esi amata polyglucose nke ?ma? ;

Iji zere mgbagwoju anya, nd? na-az? ah?a nwere ike ?mata ?d?iche d? na polyglucose na shuga site na:
