4, i-D-Alanine isetshenziswa njengezinto ezingavuthiwe zokuhlanganiswa kwama-sweeteners anoveli kanye nezinye izidakamizwa ze-chiral.
I-5, i-D-Alanine isetshenziswa kakhulu ekuhlanganiseni i-pantothenic acid ne-calcium pantothenate, i-carnosine, i-pamidronate, i-balsalazide, njll., futhi isetshenziswa kakhulu kwezokwelapha, ukudla, ukudla kanye neminye imikhakha.Ibuye isetshenziswe kuma-electroplating corrosion inhibitors kanye nama-biochemical reagents.
I-6, i-D-Alanine isetshenziswa kakhulu njengesengezo sokudla okunempilo kanye nesinongo embonini yokucubungula ukudla.Ingasetshenziswa futhi embonini yezokwelapha.
7. I-D-Alanine inobusha obuhle futhi ingakhuthaza imiphumela yezinongo zamakhemikhali;Inobumnandi obungavamile futhi ingathuthukisa ukunambitheka kwama-sweeteners okwenziwa, ithuthukise ubumuncu be-organic acid kanye ne-flavour yeviniga;Ubumuncu bayo bungasiza usawoti ukuthi ungene emifino, uthuthukise ikhwalithi yemifino enosawoti noma isoso-pickled, unciphise ubude be-pickling futhi uthuthukise ukunambitheka;
8. I-D-Alanine ingasetshenziswa njenge-corrector noma i-buffer ekubunjweni kwewayini noma isiphuzo esithambile, ingavimbela iwayini le-bubble ekugugeni futhi linganciphisa iphunga lemvubelo;
9. Umsebenzi wayo we-antioxidation ungasetshenziswa ekucubunguleni ukudla.Isibonelo, ingasetshenziswa emafutheni, kujemu we-yolk, ukudla okuhlanjululwe, ukudla okufakwe amasoso, nokudla okufakwe emanzini anosawoti ka-bra.Kungabavikela kokubili ku-oxidation futhi kuthuthukise ukunambitheka kwabo;
10. I-D-Alanine ingasetshenziswa njengezinto ezingavuthiwe zokwenziwa kwe-Vitamin B6 kanye nezinto zocwaningo mayelana nokugaywa kwama-amino acid ngezinto zezokwelapha noma ngokwesisekelo samakhemikhali ezinto eziphilayo.
