A process for the preparation of spray-dried infant food containing 26% of protein and 18% of fat is described. The product is based on a blend of coconut protein, groundnut protein isolate, skim milk powder, dextrins and hydrogenated groundnut 011 and is fortified with vitamins and minerals. It is light cream in colour and reconstitutes readily in water. Laboratory samples are free fromEscherichia coli and other pathogenic anaerobes and the total plate count is of the order of 15,60o/g. When packed in polyethylene bags (100 gauge) and stored in tin containers a t 37O, it kept well for g months, the losses of vitamins A and C and thiamine a t the end of the storage period being 25, 32 and zo%, respectively.
Aim: To develop in vitro propagation protocol of a rare, vulnerable and endangered important medicinal plant Operculina turpethum (L.) Silva Manso (Trivrit) through organogenesis. Materials and methods: Seeds collected from Institute's garden were pretreated and inoculated on Murashige and Skoog (MS)medium. Cotyledon, axillary bud and nodal segments of in vitro grown plants were used as explants. Explants were cultured on half MS, MS, whites plain medium and MS supplemented with different concentrations and combinations of plant growth regulators viz., BAP, AS, Kn, NAA, IAA, IBA. Cultures were incubated at 22 o C + 2 o C and 8 hours photoperiod with light intensity of 3000 lux. Observations were recorded at an interval of 15 to 25 days.
Result:The average maximum number of shoots 19.72 + 0.240 achieved on MS supplemented with BAP (3 mg/L). 100% root induction was obtained on half MS, MS, Whites medium alone and the combination of MS with 1 to 4 mg/L concentrations of NAA, IBA, IAA. In vitro developed plantlets were transferred in the pots; which were easily acclimatized and established in the soil.
Conclusion:The developed micropropagation protocol is beneficial for the rapid proliferation of shoots and root. The protocol would be helpful for mass multiplication as well as to conserve the rare and endangered plant of Trivrit.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
