Abstract

Defatted coconut kernel is the major by-product of the dry method of virgin coconut oil (VCO) processing which includes high fiber content. It is ground into a fine powder, has a high potential to use as a composite matrix for baked food items with wheat flour. The aim of this research is to compare nutritional characteristics of defatted coconut flour incorporated biscuits (CF), desiccated coconut incorporated commercial biscuits (DC) and wheat flour-based commercial biscuits (WF) using white bread (WB) as a reference. Proximate composition (moisture, ash, crude fat, crude protein, crude fiber and carbohydrate), Hydrolysis Index (HI) and Predicted Glycemic Index (PGI) of samples were performed through standard in-vitro analysis methods. Results of the proximate analysis revealed that moisture (36.67±0.16 %) and protein (13.35±1.17 %) content of bread were significantly (p<0.05) higher while fat, fiber and ash content of CF incorporated biscuits were significantly (p<0.05) higher with the values of 26.67±1.87 %, 3.53±0.10 % and 4.70±2.61 % respectively. Free sugar glucose content (FSG) of WF was observed the highest significant (p<0.05) value of 5.88±1.03 % while the highest amount of rapidly available glucose (RAG) (81.45±5.27 %), slowly available glucose (SAG) (59.81±7.58 %), total glucose (TG) (99.16±5.56 %) were observed in reference food of bread. The PGI of three biscuit types belonging to the medium glycemic food with the values of 60.84, 64.53 and 62.90 respectively for CF, DC and WF treatments.

Abstract

The value addition to the by-products enhances the profitability of the industry with a zero-waste concept. Defatted desiccated coconut flour (DCF) is a residue after the extraction of virgin coconut oil (VCO). This research aims to identify the effect of a variety of coconuts on the physical, nutritional and functional quality of DCF compared to whole wheat flour (WWF). Mature coconuts of four different varieties: Tall×Tall (TT), Ran Thambili (RT), San Ramon (SR), and Gon Thambili (GT) were used for the VCO extraction process by the cold press extraction followed by conversion of residue into flour (DCF). The average residue recovery is 15.33 ± 0.41% (p>0.05). The particle size of DCF is significantly higher than WWF, and only 23.16% of DCF is at the 250 µm level. The highest wettability (27.46±0.00 s) and swelling capacity (49.00±0.00 ml) have been identified in GT with a significantly (p

Abstract

Coconut (Cocos nucifera) sap is a nutritious liquid which oozes from the phloem vessels of coconut inflorescence. Dried coconut sap powder was developed as an instant beverage from unfermented coconut sap collected from a novel sap collection device and its quality was assessed. The sap was mixed with maltodextrin (DE-10) (Treatment 1; 3%, Treatment 2; 4%, Treatment 3; 5% and Treatment 4; 6%) and the solution was fed to a spray dryer. The powder of sap was packed in a triple-laminated aluminium pouch and stored at 4±2 oC for quality analysis. The data was analyzed through Minitab 16 software. The recovery percentage of powder was 17.05±2.45% and it showed good quality character for moisture (0.80±0.20%), bulk density (0.05±0.00 g/L), tapped density (0.068±0.00 g/L), hygroscopicity (19.05±0.34%), and solubility (96.72±0.87 %). The browning index (13.53±0.00) and lightness (86.75±2.17) of the sample were assessed. Scanning electron microscopic (SEM) view showed an even distribution of particles. The dilution ratio (D1:8 %, D2: 10 %, D3: 12 %) of powder was analyzed through sensory evaluation. Appearance and odour of the beverage were not affected significantly (p>0.05) with the dilution ratio. The analysis showed that it contained protein (1.44 ±0.11%), ash (0.99±0.01%), mineral (Na: 15.4±0.13mg/Kg, K: 369.4±0.87 mg/Kg, Ca: 46.8±0.89 mg/Kg, Mg: 7.7±0.52 mg/Kg), crude fiber (0.08±0.01%), total sugar (90.67±2.66%), moltodextrin (24.40±2.55%), sucrose (31.47±2.77%), glucose (16.04±0.23%), fructose (18.76±1.25%) and total phenol (138.69±0.17 mg GAE/ 100 g). One cup (100 ml) of sap contains higher nutrients with natural minerals to achieve high consumer demand.
