Soybean pods stored in plastic bags flushed with nitrogen at 4 C
exhibited similar color change and water loss as those stored in air
at 4 C. However, a strong alcoholic odor was detected after 48 h,
indicating that anaerobic respiration occurred in vegetable soybean
under nitrogen atmosphere.
The sugar compositions of fresh vegetable soybean stored in
nitrogen at 4 C for 28 days are listed in Table 4. Glucose, fructose
and sucrose decreased, with 03-CB14 displaying greater reduction
of these sugars than did V95-7456. Sucrose decreased from 52.8 to
44.5 mg/g in V95-7456, and from 67.7 to 51.4 mg/g in 03-CB14.
Raffinose in 03-CB14 did not change, while raffinose in V95-7456
decreased from 1.0 to 0.2 mg/g in 48 h, and then accumulated
gradually to 0.6 mg/g during storage. Stachyose was not detected in
both genotypes during storage
