| Abstract: | An attempt has been made to determine
proximates, nutritive value, elemental composition and heavy metal content of
the ripe, unripe pulp and seeds of Ziziphus
rugosa Lamk. for two years (2009 and 2010). The edible parts of the pulp
and seeds were separately analyzed with reference to their unripe and ripe
conditions. The macronutrients studies of pulp reveal that nitrogen was the
highest which was followed by potassium, calcium, sodium, magnesium and Phosphorus
in case of unripe pulp, whereas in case of ripe pulp nitrogen was followed by
potassium, magnesium, sodium, calcium and Phosphorus. Among the micronutrients
iron was the dominant element which was followed by manganese, zinc and copper
both in ripe and unripe pulp, respectively. The heavy metals, lead and cadmium
were recorded only during 2009 and the lead was highest and values of cadmium
were low not only in ripe pulp but also in unripe pulp. Among the components of
nutritive value the moisture was the highest which is followed by
carbohydrates, ash, fat, fibre and proteins, in case of unripe pulp, whereas in
case of ripe pulp, the moisture was followed by carbohydrates, protein, fibre,
fat and ash contents. In seeds, among the macronutrients nitrogen, was again
the dominant and which was followed by potassium, magnesium, phosphorus and
calcium in case of ripe seeds and nitrogen was followed by potassium,
phosphorus, magnesium, sodium and calcium in unripe seeds, respectively. In
case of micronutrients, iron was the dominant metals which was followed by
manganese, zinc and copper both in unripe and ripe seeds. The lead was the
dominant heavy metal not only in ripe seeds but also in unripe seeds. Among the
proximates, the carbohydrates was the dominate proximate which was followed by
moisture, fat, fibre, ash and protein in case of ripe seed and carbohydrates
was followed by moisture, protein, ash, fat and fibre in case of unripe seeds.
Between the pulp and the seeds, the seeds have more nutritive value than that
of pulp and again the unripe seeds are more nutritious than the ripe seeds. The
variation of macronutrients and proximates between unripe and the ripe
components in pulp and seeds is statistically significant (P=0.00032 for
pulp and P=0.00052 for seeds and P=0.000158 for pulp and P=0.0032
for seeds, respectively). At the same time variation of micronutrients between
pulp and seeds is not significant (P=1.426 for pulp and 4.227 for seeds,
respectively). The average values of proximate, nutritive values and elemental
components of pulp of Z. rugosa are
compared with Recommended Dietary Allowances (RDA) values and discussed.
Further, the uses of pulp of fruits to establish cottage industries to improve
economic and social condition of local people are appended.
