Effect of Packaging on Shelf-life and Lutein Content of Marigold (Tagetes erecta L.) Flowers

Abstract

LDPE pack was the best design among the ten package designs, in preserving lutein content of marigold flowers and extending their shelf lives. This economically viable packaging can not only boost the export potential of this ornamental flower, but also allow utilization of nutraceutical potency of lutein.

Polypropylene-based packaging materials for shelf-life enhancement of yellow corn (Zea mays) kernels: Effects on lutein, aflatoxin content, sensory, and nutritional profiles

“…This phenomenon of enhanced lutein content with progression of storage period could be attributed to “carotenogenesis” in the stored corn kernels, which is reported here for the first time for HKI 193‐1F variety of corn. These results are also in agreement with our previous finding on occurrence of “carotenogenesis” in African marigold flowers during senescence, wherein highest production of lutein (under experimental conditions) occurred on day 9 of storage at ambient conditions (Pal, Ghosh, & Bhattacharjee, ). In the current study, no carotenogenesis was observed in the control set during the entire storage period; rather a steady decline in lutein content was found from day 30 onward, until the end of their shelf‐lives.…”

“…Hence in the current study, it could be stated that, low oxygen permeability (indicated by low OTR) of PP/PET/Al bags (Table ) resulted in better protection of cellular protein of the packaged samples. These findings of higher retention of cellular protein in packaged corn grits vis‐a‐vis their non‐packaged counterparts are in consonance with our previous findings on LDPE‐packaged marigold flowers (Pal et al, ).…”

“…Lutein content of the corn samples were estimated by HPLC-PDA analysis in accordance with the method reported in our previous investigation on extension of shelf-lives of African marigold flowers by packaging (Pal, Ghosh, & Bhattacharjee, 2016).…”

“…Furthermore, storage time and packaging material type in combination (X 1 X 2 ) also showed significant changes (p 5 .000) on lutein content. occurred on day 9 of storage at ambient conditions (Pal, Ghosh, & Bhattacharjee, 2016). In the current study, no carotenogenesis was observed in the control set during the entire storage period; rather a steady decline in lutein content was found from day 30 onward, until the end of their shelf-lives.…”

EVALUATION OF DIFFERENT PRESERVATIVE SOLUTIONS AND PACKAGING MATERIAL FOR IMPROVING POST HARVEST QUALITY OF GLADIOLUS (Gladiolus grandiflorus) CUT SPIKES

“…Furthermore, dry packaging using polyethylene sheet controlled the microorganisms (bacterial) growth at the base of cut spikes and prevent vascular blockage and increase water uptake (Amin, 2016). In marigold flowers, low-density polyethylene packaging increased vase life up to 8 days as compared to 4 days in control packaging (Pal et al, 2016). The packaging of rose "First Red" cut stems with the polyethylene sheet and corrugated fibre board box improves flower opening, vase life and overall quality (Bhaskar and Rao, 2018).…”
