GROUP 2: HOW TO EXTRACT ESSENTIAL OIL FROM ROSE FLOWER

2023-10-24 02:43:02 UTC

Step 1:
Bring a few inches of water to a boil in a saucepan, then remove from heat.Pour a cup or so of oil into a glass jar. (Zander Jhon Wabe)

Step 2:
Look for an oil that doesn't have much natural odor to avoid competing with the roses. Jojoba and grapeseed oil are good choices, but olive oil (opt for the lighter kind) will work in a pinch. (Reynjan Nino Ladra)

Step 3:
Crush, shred or "bruise" a cup of rose petals and place in the oil. Swirl the jar around to coat the petals, but don't shake. (Novy Cymhar Gallocanta)

Step 4:
Cover the jar and place it into the hot water. Warming the oil will help release the scent from the rose petals. When the water cools, you can move the jar to a warm area like a sunny windowsill. (Gabrielle Meijas)

Step 5:
Leave the jar alone in the warm area for at least 24 hours.
Strain the oil through a cheesecloth, pressing the petals to extract as much oil as you can.
If you want a stronger-smelling oil, you can repeat steps 1-6 with fresh petals. You may need to repeat the process 5 or 6 times to get the desired level of scent. Pour clear oil into a dark bottle with a lid (dark glass will help block out sunlight and keep the oil more stable). (Aizhel Charie Salon)

GROUP 1: Steps on how to Extract Essential oil from Lavender 🪻

2023-10-24 02:59:51 UTC

STEP 1: -Harvesting: (Alannah Madison S. Cabang) Choose a time when the lavender flowers are fully bloomed and the plant is dry. Harvest the lavender bunches by cutting them close to the base of the plant.

STEP 2: -Drying: (Rebekah Maryanna S. Tacandong) Hang the harvested lavender bunches upside down in a cool, dark, and well-ventilated area such as a garage or a drying room. Allow the lavender to dry completely for approximately two to three weeks, or until the flowers feel crisp and break apart easily.

STEP 3: -Stripping: (Chloe Carmel S. Destua) Once the lavender is dried, strip the flowers from the stems by running your fingers along the stem in the opposite direction of the flowers. Collect the flowers in a clean container, discarding any leaves or stems.

STEP 4: -Crushing: (Rayne Maxcell R. Duay) Place the stripped lavender flowers in a mortar and gently crush them using a pestle. This will help release the essential oils from the flowers.

STEP 5: -Distillation: (Tiffany Sugar T. Autor) There are several methods for lavender oil distillation, but the most common is steam distillation. You can use a distillation apparatus or a DIY setup called a steam distillation kit. In this process, the crushed lavender flowers are placed in a still with water. When heated, steam passes through the flowers, vaporizing the essential oil. The steam containing the essential oil is then condensed, and the oil and water are separated.

STEP 6: -Separation: (Alannah Madison S. Cabang) Once the distillation process is complete, the essential oil will float on the surface of the water. Use a separation funnel or a pipette to carefully collect the essential oil, being cautious not to pick up any water or impurities.

STEP 7: -Filtering: (Tiffany Sugar T. Autor) To remove any remaining impurities, filter the collected essential oil through a fine mesh or a coffee filter. This will ensure that the final product is pure and free of any debris.

STEP 8: -Storage: (Chloe Carmel S. Destua) Store the extracted lavender essential oil in a dark glass bottle, preferably amber or cobalt blue, to protect it from light and UV rays. Ensure the bottle is tightly sealed and store it in a cool, dark place to maintain its potency and shelf life.

Remember, essential oil extraction requires careful handling and attention to detail. It is essential to follow safety guidelines and use appropriate equipment during the extraction process.

Group 4: Extracting of Sunflower Oil

Step 1: Loraine L. Cabello

Cleaning the seeds

Cleaning the Seeds The harvested sunflower oil Seeds are passed over Magnets to subtraction any metal traces. and other impurities are getting rid of by cleaning sieve and destoners. then the outer covering (hulls) of the seeds are removed to get pure seeds.

Step 2: Kate L. Virtudazo

De-hulling

- De-Hulling Sunflower seeds contains about 20% to 30% hulls that are sometimes removed before oil extraction to ensure the quality of both oil and sunflower meal. De hulling is completed when the seed has a moisture content of 5% after cleaning. The procedure includes cracking the seeds by the mechanical action.Then the resultant of the mixture is winnowed to separate the hulls from the kernels.

Step 3: Rue Mayelle S. Bajao

Grinding the seeds

The de-hulled seeds are ground into coarse meal to give a larger surface area to be pressed. Grooved rollers are mainly used to crush the coarse meal into a uniform fine particles. Then the coarse meal is boiled to enable the oil extraction, though impurities are released with oil during this procedure and such impurities should be removed before the oil is declared edible.

Step 4: Abigail Elisha B. Roque

Pressing

The heated meal is fed into a screw press which progressively increases the pressure from 60 kps to 950kps, to 850kps as the meal is passed through a slotted barrel. At the same time, the oil is squeezed out during the slots in the barrel and recovered.

Step 5: Thaddeus I. Llagas III

EXTRACTION OF THE ADDITIONAL OIL

Volatile hydrocarbon solvents are used to procedure the remaining oil cake through solvent extraction so as to achieve maximum yields. The most normally used solvent is hexane which dissolves the oil out of remaining oil cake. The solvent is then distilled out of the oil, passed during the matter and then collected at the bottom.

Step 6: Kate L. Virtudazo

REMOVAL OF SOLVENT TRACES

Around 90% of the volatile solvent left in the extracted oil, evaporates and it’s composed for reuse. Then a stripping column is used to recover the remaining solvent. In this procedure, the oil is boiled by steam and the solvent evaporates, condenses and is collected separately.

Step 7: Abigail Elisha B. Roque

OIL REFINING AND PROCESSING

Extracted and desolventized sunflower oil should be further processed to create an edible product. Edible oils are refined to develop the flavour, odour, colour and solidity using processes that degum, neutralize, bleach and deodorize the oil. These oil refining processes eliminate contaminants such as phosphatides, free fatty acids, and pro-oxidants.
Further processing of sunflower oil and fats is sometimes de4sired. Some oils are winterized or dewaxed and some are modified to differ melting characteristics. By-products can be more processed to create value-added products or reduce costs.
The final stage involves deodorizing the oil bypassing the steam over hot oil placed in a vacuum at temperatures between 225 C and 250 C. This allows the volatile components steady for the taste and odour to evaporate from the oil. One percent citric acid is added to the oil to inactivate some trace metals present, thus preventing oxidation within the oil, thereby prolonging the shelf life of the oil.

Step 8: Rue Mayelle S. Bajao

PACKING THE OIL

Pure oil is measured or packed in clean containers, and the usual ones are bottles for domestic sales in specialty stores, or cans for exports.

(Shaira) Step 1: Collect lily flowers early in the morning when their fragrance is most potent .

(Blair) Step 2: Collect the flower petals. Then rinse it with clean water to prevent dirt.

(Renzo) Step 3:Okay step 3 you have to put the lily petals in a clear glass and cover the petals in carrier oil or almond oil. Make sure petals are submerged and seal it tightly. Leave it for 2 days.

(Christelle) Step 4:After that process filter the oil using a fine-mesh sieve or cheesecloth to separate the petals from the oil. Squeeze the petals gently to extract any remaining oil.

(Xaki) Step 5: After finally extracting the oil, use a funnel to pour the contents/oil into a dark tinted glass bottle and be sure the bottle has a secure seal. So that the oil may be preserved longer.
