This paper presents the experimental results of the oil extraction process from wild almond seeds by mechanical and chemical methods. The optimum conditions for the biodiesel production from the extracted oil via transesterification reaction using methanol and potassium hydroxide (KOH) are reported. Chemical extraction was found to be an effective technique for wild almond oil extraction. Simple distillation was used as oil extraction unit applying 140 ml of n-hexane as solvent at 70ºC for 20 min. The oil yield was 43.11±0.98%. This extracted oil was used as raw material for biodiesel production with the maximum yield of 83.20±1.11%. The optimum conditions for biodiesel production were the catalyst loading of 0.5 wt% and 9:1 molar ratio of methanol to oil in a controlled reaction temperature of 70ºC for 60 min. Finally the properties of biodiesel were analyzed and most properties met the requirements of the department of energy business standard.

The studies of Dietary Fiber Supplement by coconut flour from coconut Wastes Oil Extraction process in Bakery Product was investigated Production of coconut flour from coconut wastes oil extraction drying at 55 ° C for 12 hours and then grinding to powder gave the off-white fine powder. The chemical compositions of coconut flour were 57.70 % carbohydrate 29.4 % fat 6.23 % moisture 5.20 % protein and 1.48 % ash by dye weigh. Butter cake making experiment by substitution of wheat flour with coconut flour at 5 % of wheat flour weigh which has the highest sensory scores comparing butter cake with the control found that increase dietary fiber 1.34 g. /100 g. The majority of the tested consumers (92%) accepted butter cake with 5 % of coconut flour substitution. Muffin making experiment by substitution of wheat flour with coconut flour at 15 % of wheat flour weigh which has the highest sensory scores comparing muffin with the control found that increase dietary fiber 2.34 g /100 g. The majority of the tested consumers (81%) accepted muffin with 15 % of coconut flour substitution. Cornflake cookie making experiment by substitution of wheat flour with coconut flour at 20 % of wheat flour weigh which has the highest sensory scores comparing cornflake cookie with the control found that increase dietary fiber 3.54 g. /100 g. The majority of the tested consumers (94 %) accepted cornflake cookie with 20 % of coconut flour substitution. Butter cookie making experiment by substitution of wheat flour with coconut flour at 10 % of wheat flour weigh which has the highest sensory scorescomparing butter cookie with the control found that increase dietary fiber 3.04 g. /100 g. The majority of the tested consumers (94 %) accepted Butter cookie with 10 % of coconut flour substitution. Frozen cookie making experiment by substitution of wheat flour with coconut flour at 20 % of wheat flour weigh which has the highest sensory scores comparing cookie with the control found that increase dietary fiber 4.02g. /100 g. The majority of the tested consumers (93 %) accepted 20 % of coconut flour substitution. Butter bread making experiment by substitution of wheat flour with coconut flour at 15 % of wheat flour weigh which has the highest sensory scores comparing butter bread with the control found that increase dietary fiber 2.22 g. /100 g. The majority of the tested consumers (75 %) accepted 15% of coconut flour substitution. Whole wheat bread making experiment by substitution of wheat flour with coconut flour at 15 % of wheat flour weigh which has the highest sensory scores comparing whole wheat bread with the control found that increase dietary fiber 2.09 g. /100 g. The majority of the tested consumers (79 %) accepted 15 % of coconut flour substitution. Pie crust making experiment by substitution of wheat flour with coconut flour at 15 % of wheat flour weigh which has the highest sensory scores comparing pie crust with the control found that increase dietary fiber 2.91 g. /100 g. The majority of the tested consumers (82 %) accepted 15 % of coconut flour substitution.
