Abstract
An experiment entitled, “ Studies in qualitative changes in surangi (Mammea suriga)
flowers during storage” was conducted at the laboratory of Department of Post harvest
management of Medicinal, Aromatic, Plantation, Spices and Forest crops, Post Graduate Institute
Post Harvest Management, Killa-Roha during the year 2021-22.
The standardization of harvesting stage for higher yield of essential oil content and to
study the qualitative changes in surangi flowers during storage are the major objectives of
research experiment. Physical, chemical and quality parameters were evaluated against three
harvesting stages with five days duration of storage using buds and flowers of surangi. The
experiment was carried out with three main treatments, and five sub- treatments and their
interaction.
Weight of buds and flowers was decreases 100 (g) to 87.4 (g) during storage period,
moisture percentage was also decreases 26.23 (g) to 20.96 (g) and variation found in three
harvesting stages samples recovery of essential oil percentage was decreased 0.78(%) to
0.39(%)during storage period of buds and flowers. Colour L* value and colour b* value was
decreased. Due to the loss of weight and moisture number of buds and flowers was increased.
Total phenol percentage and trans-alpha-bergamotene percentage of three different harvesting
stages samples of extracted essential oil was found some variation in the result. Specific gravity,
refractive index and optical rotation of all the three harvesting stages extracted essential oil
found at par values of this quality observations. After fixing of standardization of suitable
harvesting stage for higher yield of essential oil contents. This fresh flowers of surangi correct
harvesting stage is very important to get economical returns to the farmers for handsome returns.
All the three stages in which bud stage, fully opened flowers stage and naturally dropped flowers
stage in which buds and flowers are stored up to five days then we can verify the effect of
qualitative changes in flowers and buds as well as to study effect on oil yield recovery.
