Biplot of germination, EC and various biochemical attributes of quinoa seeds stored in different packaging materials at varying levels of seed moisture contents. S, Super Bag; P, Paper bag; PP, Polypropylene bag; J, Jute bag, C, Cloth Bag. Initial moisture levels: 8, 10, 12 and 14%.

Moisture absorption through jute bags and the moisture content of wheat grains after 2 months of storage. (A) Total moisture absorbed through control jute bags (CJBs: unfilled shapes) and wax-coated jute bags (WCJBs: filled shapes) over the seed-storage period. Total moisture absorbed was taken as the sum of moisture uptake by jute bags and stored grains; the combined mean mass of the storage bag plus seed was ~ 170 g/bag. (B) Post-storage seed moisture content (SMC) of stored wheat grains at different relative humidity (RH) conditions. Horizontally-dotted line (SMC₀) represents initial SMC (7.1%) before storage; error bars represent the standard errors (± SE) of means from three replicates.

Scores of the first two principal components. TFFA = total free fatty acids. Beginning of storage (1-0: FP1-PMA = foil pouch packaging with passive modified atmosphere; 2-0 FP1-AMA = foil pouch packaging with active modified atmosphere; 3-0: FP1-V = foil pouch packaging with vacuum; 4-0: GP = GrainPro^® bag; 5-0: J-CW = jute bag in conventional warehouse; 6-0: J-CC = jute bag in controlled chamber; 7-0: FP2-PMA = foil pouch packaging with passive modified atmosphere; 8-0: S-GP = bag similar to GrainPro^®). After 12 months of storage (1-12: FP1-PMA; 2-12: FP1-AMA; 3-12: FP1-V; 4-12: GP; 5-12: J-CW; 6-12: J-CC; 7-12: FP2-PMA; 8-12: S-GP)

Capsaicin and dihydrocapsaicin concentrations in hot peppers viz. Sky Red (A), Maha (B) and Wonder King (C) at different temperatures and packaging materials (PB, polyethylene bag; JB, jute bag) during five months’ storage. Vertical bars show ± SD of n = 3 replicates.

Side by side storage of PICS, PP and Jutes bags during the experiment at the KARLO research station in Kiboko, Kenya. Insects seriously damaged PP and Jute treatments, as reflected in the dust produced.
