Biochemical Evaluation Of Avocado Pear Leaf (Persea Americana)


Abstract


Chemical evaluation of Avocado Pear leaves. During the process of my research temperature for drying the sample was not high to avoid protein denature temperature between 50oc and 60oc was used. the proximate analysis which include the carbohydrate determination was 69. 65%, SD ± 0.01, the protein was 14.00%, SD ± 0.01, the crude fat was 7.3%, SD ± 0.02,the crude fibre was 3.7%, SD ± 0.04 the ash content was 5.26% ± 50 0.01, the moisture content was 59.84%, SD ± 0.02 and the caloric value was 401.11kcal. SD ± 00.1. the anti-nutrients determination includes; the hydrocyanide (HCN), which was 104.17mg/100g, SD ± 0.01, the phytate with 30.40mg/100g SD ± 0.01 the oxalate with 158.40mg/100g, SD ± 0.01, and the tannins with 1361.19mg/100g, SD ± 0.02. and also, the antioxidant vitamins determination which includes; the vitamin A and C. the Vitamin A determination was found to be 70.00mg/100g, SD ± 0.01, and vitamin C determination was reported as 832.72mg/100g, SD ± 0.01.

Keywords; Avocado leaves, Carbohydrate, Protein, Hydrocyanide, Phytate, Vitamins.

How to defend your research work


This is a general guide on how to defend your research work:

1. Prepare For Questions:

If you are preparing for questions that may be asked during your defense, then your answers will flow smoothly and effectively. This will prove your knowledge on the subject e.g “Biochemical Evaluation Of Avocado Pear Leaf (Persea Americana)“, and strengthening your argument. Ask friends and family, read your work for them to listen to your presentation, and write down questions. You may be lucky the panel will ask you those you have already prepared on.

2. Strong Summary:

Summarizing your chapters will help keep your audience focused because it is easy for a mind to drift, so providing summaries will ensure your panel will follow along, even if they lose focus for a brief moment. Visual aides, such as graphs and power-point presentations can be very helpful. If you are going to use these, make sure you will practice your presentation with them.

3. Be Confident in Your Research Work:

Not knowing your topic “Biochemical Evaluation Of Avocado Pear Leaf (Persea Americana)” inside out will cause you to struggle and ultimately fail with your defense. You need to know the subject from every angle to ensure you are fully prepared for any question that may come your way.

4. Conclusion:

Reinforce your findings to conclude your defense. The finale of your presentation should focus on proving the work that has been done. You may need to recap on what has changed and remained unchanged, if is necessary.

5 . Listen:

Before you get defensive or recite a particular answer, make sure you truly understand the question being asked. Being a good listener is an important quality, because providing an inaccurate or off-topic answer will also weaken the validity of your paper.
