The purpose of this study was to evaluate the lycopene and beta carotene concentration in aril oil of gac as
influenced by extracting solvents and drying methods. The solvent extractions namely chloroform:methanol
(2:1 v/v), petroleum ether and hexane were evaluated for optimal extracting solvent of each carotenoid.
Three different drying methods were used including hot-air (HA), low relative humidity air drying (LRH) and
far-infrared radiation (FIR). The extracts of different solvents were exhibited to have different levels of
lycopene and beta-carotene. Chloroform:methanol (2:1 v/v) showed higher lycopene and beta-carotene
content in aril oil (0.49 and 1.18 mg/g) than that of fresh aril (0.045 and 0.009 mg/g). Among the different
drying methods, HA was found to provide the highest amount of lycopene (0.82 mg/g DW) in the aril oil,
followed by FIR (0.67 mg/g DW) and LRH (0.56 mg/g DW). Interestingly, HA dried aril oil had higher content
of lycopene than that of control (fresh). However, processing methods are known to have variable effects on
bioactive compounds of plant samples. Effects could vary from little or no change to significant losses, or even
enhancement in antioxidant properties.

Lub hom phiaj ntawm txoj kev tshawb no yog ntsuam xyuas tus lycopene thiab beta carotene concentration nyob hauv aril cov roj ntawm gac li
pawg extracting kuab tshuaj thiab kom qhuav txoj kev. Cov kuab extractions namely chloroform: methanol
(v/v 2:1), roj av ether thiab hexane yeej ntsuam rau noj extracting hnyav ntawm txhua carotenoid.
peb drying kev sib txawv tau siv xws li kub-cua (HA), uas tsis muaj tus txheeb ze vaum pa kom qhuav (LRH) thiab
far-infrared tawg (FIR). Cia tus uas txawv cov kuab tshuaj muaj tshaaj muaj txawv muaj ntau seem
lycopene thiab Beta Carotene. Chloroform: methanol (2:1 v/v) tsom lycopene dua thiab beta carotene
nyob hauv aril cov roj (0.49 thiab 1.18 mg/g) dua cov tshiab aril (0.045 thiab 0.009 mg/g). Cov tus sib txawv
kom qhuav li, HIS hais kom muab tus nqi ntau tshaj plaws lycopene (0.82 mg/g DW) nyob rau hauv roj, aril
taug ntawm FIR (0.67 mg/g DW) thiab LRH (0.56 mg/g DW). Interestingly, HIS aril qaug roj muaj ntau cov ntawv
ntawm lycopene dua uas muaj kev tiv thaiv (cov). Tiam sis, ua kev paub los kuj tsis paub meej
bioactive tebchaw ntawm tsob nroj kuaj. Los yuav sib txawv ntawm me ntsis los yog tsis muaj kev hloov rau cov teeb meem loj losses, los sis txawm
li hauv antioxidant zog.
