Ascorbate concentrations were expressed as mg 100 g−1 on fresh weight basis.

The total phenol content in fruit tissue was estimated using the

Folin-Ciocalteu colorimetric method as described by Gonz´alez-

Aguilar et al. (2004).

For total phenol extraction, 2 g of guava fruit was homogenized with 5mL of ethanol with a tissue homogenizer (Model Virtis, USA).

After 2 h in the dark, the

mixture was filtered using Whatman paper No. 1. The reaction

mixture consisted of 40 _L of the total phenol extract, 50 _L

ethanol, 400_L water, and 5_L of a solution containing 2 g of

sodium carbonate in 100mL 0.1N NaOH and 500 _L of half

strength Folin-Ciocalteu reagent.

After 30 min of reaction time,

the absorbance of solution was read in a spectrophotometer set

at 724 nm and concentrations were calculated by preparing a

gallic acid standard curve.

2.6. Skin colour index

Subjective rating of skin colour of guava fruit was done

after 30 days storage on a 1–5 scale where: 1, <20% yellow;

2, 20–40% yellow; 3, 40–60% yellow; 4, 60–80% yellow; 5,

>80% yellow. These colour stages were even found useful to

define the ripening stage in the coloured cultivar, ‘Apple Colour’

as the background colour dominated.

    在30天之後,儲存在1-5個規模: 1 , “ 20 %的黃色;

    2 ,黃色的20-40 % ; 3 ,黃色的40-60 % ; 4 ,黃色的60-80 % ; 5 ,

    “ 80 %的黃色。這些膚色階段,甚至找到有用的

    確定了成熟階段,有色品種,蘋果色'

    作為背景顏色為主。
