This paper investigated the extraction of edible oil from the pulp of avocado fruit by means of the cold process. Avocado pear fruit was collected washed, peeled, de-stoned, blended, and heated at 60 °C for 90 mins and then malaxed. No chemical solvent was introduced, as the blending of the pulp required only the addition of water. The process involves centrifuging the Avocado pulp via a laboratory centrifuge at 7000 rpm for 15 mins. While the solid pulp remained in the bottom, the liquid (oil-water mixture) floated on top. The mixture was dried for an hour using a heating mantle and then filtered using filter paper to remove the suspended pulp particles. A dark greenish brown oil was thus obtained with a yield of 6.3 %. The physicochemical properties of the oil in terms of acid value, saponification value, ester value, % FFA, % glycerine, specific density and moisture content were found to be 23 mg KOH/g oil, 199.7 mg KOH/g oil, 176.7 mg KOH/g oil, 11.5%, 9.66%, 1.19 g/L and 75%, respectively. This process is devoid of the use of any reagent and hence, is suitable for consumption. The process requires limited labour and low temperatures, thus its nutrients, flavour, and richness are safeguarded and the product retains its healthy properties.

Obesity is a foremost but preventable cause of deaths globally. It is a significant risk factor for the development of cardiovascular diseases, particularly heart failure, and diabetes. Natural products such as some foods, fruits, medicinal plants have been known to be functional in the management of Obesity. This article is aimed at reviewing the weight loss and anti-obesity potentials of Ginger (Zingiber officinale), Avocado (Persea americana) and Green Tea (Epigallocatechin gallate, EGCG). Google Scholar, PubMed, NCBI and Elsevier databases were searched from 2004 to 2020 using specific keywords. Searching was restricted to English language. Seventeen articles (Eleven human studies and six animal studies) were included in this review. Majority of the research papers that were considered in this review supported the weight loss and anti-obesity potentials of these natural products in obese human and animal subjects by lowering most of the clinical markers of obesity. Some of the anti-obesity mechanisms proposed by the authors include suppression of lipogenesis, inhibition of ghrelin secretion, e.t.c. This article also established the need for future trials.
