Avocado oil has generated growing interest among consumers due to its nutritional and technological characteristics, which is evidenced by an increase in the number of scientific articles that have been published on it. They differ in such significant ways as length of time from bloom to fruit maturity, thickness of skin, tolerance of cold, etc. The effects of two operating parameters, pressure (20MPa, 25MPa, and 30MPa) and temperature (40 ºC, 60 ºC, and 80 ºC) on extraction yield were studied using response surface methodology (RSM). There are 12 major cultivars of avocado, but the main cultivars grown globally are Hass and Fuerte. Pulp from ripe avocados was ground and dried under microwaves or oven drying with forced air circulation. Avocado oil like olive oil is extracted from the fruit pulp and in particular shares many principles of the extraction process with extra-vergin olive oil. The avocado fruit is mainly sold fresh on the market, which however trades also a relevant quantity of second-grade fruits with a relatively high oil content. Avocado (Persea americana Mill.) Karakteristik minyak biji alpukat yang dihasilkan yaitu berwarna oranye, yield 2,8112 %, kadar air 0,0915 %, densitas 0,8138 g/ml, dan FFA 0,0997 %. A general outline is presented on the general workflow; illustrated through examples and a current review of some of the applications of design of experiments in the context of food production help provide some directives and guidelines. Crude avocado oil can be extracted from the remaining cake by refluxing with suitable solvents. Both markets are growing, and extracting avocado oil can be compared to extracting olive oil. Hibiscus sabdariffa, commonly known as Roselle, is a native plant in Malaysia that is rich with bioactive compounds. After this, the flesh is ground to a paste and then malaxed for 40-60 minutes at 45-50°C. The avocado oil-making process is: avocado-peeled, cored-dried (3-5% moisture)-crushed-hydraulic / screw press. What is unrefined, extra virgin cold-pressed avocado oil? Hass avocado (Persea americana Mill.) Finally, the dynamic extraction curves of scCO2 were modeled with a multi-way partial least squares regression (MPLSR). Extractability index could be used together with pulp oil content (on a dry matter basis) as a parameter for olive cultivar characterisation and selection for breeding projects. Since antiquity, seeds and pits from a wide variety of plants have provided humankind with oil for a multitude of applications. In some cases where a two-phase decanter is used, the liquid phase can be further processed in a centrifuge to remove the remaining CPAO from the wastewater, ...
