The percentage incidence for α-ZEL was 100% for maize, sorghum and millet samples while the percentage incidence of β-ZEL was 100% for maize and millet and 95% for sorghum samples.

Variations in color, clarity, viscosity, pH, total soluble solid, total acidity, salinity, water activity, browning intensity and 5-hydroxymethylfurfural content of the syrups were observed among the plantation areas. The nutritional compositions of the syrups also varied depending on their harvested locations. Sugar was the main dry matter presented in all the nipa palm syrups, followed by protein and ash. The energy values of the syrups were in the range of 376–413 kcal/100 g, dw. Sucrose was found as a major sugar in all syrup whereas glucose and fructose were found as minor sugars. Low amounts of natural fructan, fructo-oligosaccharide, and kestose were found only in one plantation area. The total phenolic acid and total flavonoid contents were determined in all syrup with varying concentrations. Potassium and sodium were found as major elements. Phosphorus, magnesium, silica, calcium, iron, copper, iodine, manganese, zinc, and chromium were also found at varying contents. Sugar derivatives, non-protein nitrogenous compounds, polyphenols, organic acids, and some flavor substances were identified in the nipa palm syrups by liquid chromatography-mass spectrometry. Results highlighted the variations in physicochemical properties and nutritional compositions of nipa palm syrup.

The selected yacon fruits were washed with sodium hypochlorite (200 ppm), peeled, sliced and dried at 55 °C/72 h in a forced convection tray dryer (Binder UDK 250) to obtain flour; then their approximate centesimal composition and color were determined, and subsequently sweet biscuits were made using three wheat/yacon flour mixtures in the following proportions (<em>w</em>/w): 100:00 (control), 70:30, 60:40 and 50:50; a completely randomized design with three repetitions was used.
