Hauv kev tsim cov txiv hmab txiv ntoo qhuav, cov ntsiab lus ntawm cov suab thaj sib sib zog nqus yuav tsum tau tswj ua ntej, thiab cov ntsiab lus noo noo nyob rau hauv cov txiv hmab txiv ntoo slices yuav tsum tau txo los ntawm khov-qhuav. Cov txiv hmab txiv ntoo qhuav yog ces nqus kom qhuav los tswj cov dej noo hauv cov txiv hmab txiv ntoo hauv qhov xav tau ntawm cov khoom noj ceev ceev.
1. Tev thiab core cov txiv apples tshiab, siv cov tais diav los txiav 5 kg ntawm cov txiv apples, txhua daim yog 4 hli tuab, 10 hli luv, 25 hli ntev, thiab 20 hli dav. Raus 5 kg ntawm txiv apples nyob rau hauv 20 kg ntawm syrup uas muaj 1 kg ntawm sucrose, 60 g ntawm preservative thiab 18.94 kg dej kom tau kwv yees li 7 kg ntawm txiv apples nrog 90 feem pua ntawm noo noo thiab 7.9 feem pua concentration ntawm qhov hnyav ntawm chav tsev kub thiab atmospheric siab. qab zib tov.
2. Ceev nrooj khov 7 kg ntawm txiv apples dipped nyob rau hauv syrup ntawm -30 degree, ces khov-qhuav nyob rau hauv 0.1 mmHg nqus tsev vacuum, thiab ces nce qhov kub ntawm 30 degree rau 25 teev kom tau 1 kg. ntawm cov txiv apples uas muaj 30 feem pua ntawm cov dej noo. .
3. Tam sim ntawd tom qab khov-qhuav, nyob rau hauv lub tshuab nqus tsev nyob rau hauv thaj tsam ntawm 15-30 hli Hg, irradiate kua slices nrog microwaves nrog ib tug tso zis hwj chim ntawm 4.5 kilowatts, thiab ces tsa qhov kub thiab txias rau 30 ° C rau 1 feeb kom tau txais. txog 900 grams. Kua slices.
4. Tom qab ntawd, cov txiv apples tau qhuav hauv lub tshuab nqus tsev nyob hauv thaj tsam ntawm 10-30 mm Hg, thiab tom qab ntawd qhov kub thiab txias tau nce mus rau 50 ° C. rau 30 feeb kom tau txog 800 grams ntawm cov txiv apples uas muaj. 5% noo noo.
