The Dark Glass Bottle Can Protect The Nutrients Well In Olive Oil

Olea europaea is a subtropical tree species, a typical Mediterranean climate plant, it has the characteristics of light-loving, high-temperature resistance, drought resistance, and moisture intolerance. The oil extracted from the fresh fruits of Olea europaea is called olive oil, which is a high-grade edible oil. The oil extracted from the fresh fruits of Olea europaea is called oil olive oil, which is a high-grade edible oil. Olea europaea, oil tea, oil palm, and coconuts are called the world’s four woody edible oil tree species.

Olive oil, with characteristics and production process that can be eaten after cold pressing, without high temperature and chemical substance treatment, retains all the natural nutrients in the fresh fruit. The Mediterranean coastal countries that have been consuming olive oil for a long time, have the lowest mortality rate due to cardiovascular and cerebrovascular diseases, it is recognized as the place with the highest proportion of long-lived people in the world. Olive oil has also become the main content of the “Mediterranean diet” advocated by the World Health Organization (WHO).

Olive oil is not only one of the main edible oils for humans, but also has a wide range of industrial uses, it is an important raw material for industries such as wine, beverages, medicine, daily chemical industry, textile printing and dyeing, electronic instruments, additives or lubricants.

After pressing the olive oil from the fresh olive fruit, it will produce large amounts of byproducts such as juice, pomace, and so on. Using juice and olive peel pomace can produce olive wine that is “like wine and not wine”. This kind of olive wine is fermented wine, which is different from wine made directly with fresh fruits, olive dregs can be further used to produce chicken feed.

Researchers led by Abdelilah El Abbassi at Cadi Ayyad University in Morocco found that the phenolic compounds in the by-products of olive processing have high biological activity, this evidence indicates that “these phenolics will have a beneficial effect on health”. Researchers have shown that phenolic extracts from Olive Mill Wastewater(OMW) are natural antioxidants that can be used in the formulation of functional health beverages.

Olive fruit oil is an important base oil for cosmetics. Olive leaf extract has a strong activating effect on macrophage activity. One of the functions of macrophages in the cortex is to engulf melanin, therefore, olive leaf extract has a whitening effect on the skin. Combined with its activity on melanocytes, olive leaf extract can be used in whitening cosmetics. Olive leaf extract can also be used as an acne control agent, anti-inflammatory agent, allergy inhibitor, and anti-aging antioxidant.

Olive oil is used as an additive in the food industry and dairy industry to transform the flavor. In medicine, it is used to prepare solvents and ointments for various antibiotics or vitamin injections, especially scald creams. It is mainly used as printing and dyeing oil in the textile industry, make the color easy and firm, the colors are brighter and more beautiful. In the electronics and glass manufacturing industry, it is mainly used for grinding lubricants, especially the grinding grease for high-standard electronic tubes, which cannot be replaced by other greases.

According to the European International Olive Oil Committee (IOC) standard, depending on how the olive oil is obtained, olive oil can be divided into virgin olive oil and olive pomace oil.

Virgin olive oil is extracted from the fruit of the olive tree only by mechanical means and other physical means, especially avoid excessively high temperatures to change the quality of the oil. Except for cleaning, centrifugation, and filtration, no other processes can be used. Virgin olive oil is edible and can be divided into three types: extra virgin olive oil, virgin olive oil, and ordinary virgin olive oil.

Extra virgin olive oil, Oleic acid is ≤0.8%, it is divided into two types: organic extra virgin olive oil and PDO(Protected Designation of Origin). Virgin olive oil, Oleic acid is ≤2%. Ordinary virgin olive oil, Oleic acid is ≤ 3.3%, it can only be sold to consumers if permitted by laws and regulations. The type of virgin olive oil not fit for eating is oleic acid >3.3%, can be used as kerosene or re-refined.

Olive pomace oil extracts olive pomace with solvents or other physical methods, there are three types: Crude Olive Pomace Oil, Refined Olive Pomace Oil, and Olive Pomace Oil. Crude Olive Pomace Oil is the first squeezed oil from the core and pulp of the fruit, it is not edible and must undergo a refining process.

The oleic acid of refined olive pomace oil is less than 0.3%, it is an oil product obtained by refining crude olive pomace oil. Due to its slightly lower nutritional value, this type of oil is generally mixed with other types of olive oil or used as industrial food frying oil. The oleic acid of olive pomace oil is less than 1%, it is made by mixing refined olive pomace oil and virgin olive oil, it is edible and used for cooking or fried.

Except for the standard classification, no other words can represent the grade of olive oil, words like Premium have no real meaning. Regardless of the text in front of Extra-Virgin, it is an olive oil of the same grade under the IOC standard.

Cold-pressed is also the text that appears on the bottle of olive oil. If olive oil is pressed with hot water or steam, the flavor will be reduced. In order to avoid the influence of high temperature, cold pressing was born. The EU definition in 2002, “ During olive kneading and extraction, the olive paste temperature is below 27ºC, that is cold-pressed”.

At present, the demand for olive oil in the international market is increasing, especially olive oil for meals. Olive oil is recognized as a green and healthy edible oil due to its rich nutrients and outstanding health care functions, the olive oil industry has a broad market prospect. In the latest olive oil market research of FORTUNE BUSINESS SIGNTS, pointed out that the global olive oil market in 2019 was USD 13.03 billion and is expected to reach USD 16.64 billion by 2027, the compound annual growth rate during the forecast period (2020-2027) is 3.2%.

The main reasons for promoting the growth of the olive oil market are as follows:

(1). Due to the increasing concern about food safety, consumers have more preference for safer and healthier vegetable oils. In addition, with repeated COVID-19 epidemics, people stay in isolation at home and become increasingly interested in family cooking.

(2). With the modernization of lifestyles, changes in dietary structure, and reduction in physical activity, the prevalence of obesity and cardiovascular diseases in modern people is increasing at an alarming rate. Cardio-cerebrovascular diseases are often caused by hyperlipidemia, arteriosclerosis, etc., animal fats and oils contain more saturated fatty acids, which can cause blood cholesterol to increase. Obesity and cardiovascular patients are more suitable to choose olive oil that contains monounsaturated fatty acids and has a certain effect of reducing blood lipids.

(3). The Mediterranean diet is a nutritionally balanced diet, mainly composed of fruits and vegetables, seafood, whole grains, nuts, and olive oil, as well as a small amount of beef, dairy products, alcohol, etc. It is a diet structure characterized by high dietary fiber, high vitamins, and low saturated fatty acids, which is becoming more and more popular among people all over the world. Olive oil is a commonly used oil in the Mediterranean diet, and it is also the core and focus of the Mediterranean diet.

(4). Olive oil is widely used in the daily chemical industry, it is a natural skin care product, which is rich in squalene and essential fatty acids with excellent skin affinity, can be absorbed quickly, and effectively maintains skin elasticity and moisturizing. Olive oil is rich in monounsaturated fatty acids, vitamins E, K, A, D, etc., and phenolic antioxidants, it can eliminate facial wrinkles and prevent skin aging, has the effects of skin care and hair care, and prevention of hand and foot chapped.

Olive oil is also good for postpartum skincare. Extra virgin olive oil can remove stretch marks or make them lighter. Note that if you want to use olive oil for beauty, you must buy real extra virgin olive oil, this kind of olive oil has not been refined or high temperature, but only pressed at low temperature, all nutrients can be preserved. Extra virgin olive oil can also be used to remove makeup, promote body metabolism, facial masks, lip care, etc.

Costco is second only to Wal-Mart with a market value of 320 billion U.S. dollars, it is the second-largest retail company in the world. Costco has a strong brand endorsement all over the world because of its extreme pursuit of price, extreme requirements for service, and strict control of quality. KIRKLAND SIGNATURE is COSTCO’s own brand, which has attracted much attention among many olive oil brands in North America, it has a reliable reputation and quality. It is also one of the few brands in the United States that truly meets the standards of extra virgin olive oil.

To judge the quality of olive oil, it is necessary to check the place of origin, the variety of olive fruit, the quality of the fruit, and environmental factors. These four dimensions are closely related to the aroma, taste, aftertaste, and nutritional value of olive oil, and the place of origin has a great influence on the price and quality. Among the main olive oil-producing countries, Spain accounts for one-third of the world’s total output, Italy one-fourth, and Greece one-fifth, other oil-producing countries include Turkey, Syria, Portugal, France, Egypt, and so on.

In order to protect and promote products, the EU has established three quality labels: PDO, PGI, and TSG. As long as the products meet the specifications, they will be certified. Products such as agricultural products, food, red wine, wine, and flavored wine can be applied for. The certification mark indicates that the product comes from a designated area that specializes in the production of a certain product, and its product meets EU standards.

PDO(Protected Designation of Origin), the protection system for appellations of origin, the product is originally produced in a specific city, region, or country. The quality and characteristics of the product are derived from geographical factors, as well as human factors such as traditional techniques.

PGI(Protected Geographic Indication), is similar to PDO to ensure that a product originates from a specific geographic area and has unique characteristics and quality. However, the difference is that the geographic indication protection system does not include the manufacturing process, techniques, and traditions of human factors in the investigation.

TSG(Traditional Specialty Guaranteed System), has no restriction on the place of production. On the contrary, this certification requires the use of production materials and manufacturing methods passed down from generation to generation to distinguish similar imitation products in the market.

According to EU regulations, some information on olive oil labels is mandatory to include, including net weight, country of origin, expiration date, nutritional content, and storage methods. If this part of the information in the olive oil label is missing, the quality of this product is questionable.

In order to allow consumers to trace all stages of olive oil production, that is, the planting of olive trees, the pressing of olive fruits, the storage location of the refined oil, and the final bottling and packaging location are all recorded one by one. On the product label of Costco’s Kirkland Signature extra virgin olive oil, indicating the origin, the percentage of the extra virgin in the mixture, the date of receipt of the seeds, the fruit variety, the product classification of the origin, third-party verification, and other information.

Costco has established a strict quality inspection and balance chain to determine the authenticity and safety of every link in the olive oil supply chain, such as growers, millers, bottlers, and importers. No matter in the blind taste test of olive oil, or in the sampling inspection of relevant quality inspection departments or laboratories, Kirkland Signature’s extra virgin coconut oil performs well, and it is also one of the extra virgin olive oil brands that consumers love very much.

The monounsaturated acid in olive oil is quite unstable, it will deteriorate quickly when exposed to the sun or high temperature, thus, the effect of olive oil to protect the heart and brain blood vessels is lost. At the same time, some ions in the metal may also react with monounsaturated fatty acids and affect the quality, therefore, metal packaging is not recommended. For all oils and fats, if they are in contact with the plastic for a long time, they will separate some of the plastic solidified molecules and lose their original flavor.

If olive oil is exposed to natural or artificial light sources (including halogen lamps and fluorescent lamps commonly used in large shopping malls) for a long time, not only the taste will change, but its nutrients will also be destroyed due to oxidation reactions, therefore, olive oil needs to be stored in the dark place, and the best packaging is bottled in a dark glass bottle.

The international standard packaging of olive oil is 250ml, 500ml, 750ml, 1L, 3L, 5L, etc., glass bottles are usually used to pack 250ML-1000ML olive oil, Kirkland Signature 1L extra virgin olive oil is also packed in green glass bottles. Olive oil has a thicker texture and poor fluidity, for filling volume below 5L, we have three models automatic liquid filling machine for filling Kirkland Signature olive oil with glass bottles, that is flowmeter liquid filling machines, multi-head piston viscous filling machine and mobile filling heads automatic viscous filling machine, they have many differences in filling speed, filling accuracy and filling specifications.

The flow meter liquid filling machine is a linear structure, the number of filling heads can be customized according to different production capacities, such as 2/4/6/8/10/12 filling heads, the filling volume is controlled by a flow meter and gear pump, it is an economical viscous liquid filling machine for filling 500ML-30L products, the measurement adjustment is very big. If your oil product is single, but the filling specifications are more, the required filling accuracy is not very high, it is more suitable for using a flowmeter liquid filling machine.

The multi-head piston liquid filling machine adopts a piston pump structure, which is quantified by a quantitative cylinder, and then filled under the action of pressure. The filling volume is accurate and the filling speed is fast. Because the piston metering barrels have different volumes, in order to ensure the filling accuracy, the filling specifications cannot differ much, otherwise, it will greatly affect the filling accuracy. In addition, the piston-type liquid filling machine can fill up to 5L.

The piston metering cylinder is driven by a servo motor. Through the up and down movement of the cylinder, the piston in the corresponding cylinder is driven to reciprocate at the same time, so that negative pressure is generated in the front cavity of the cylinder, and the stroke of the cylinder is controlled by a signal valve, the filling volume can be adjusted to achieve the precise filling effect.

This liquid filling machine is easy to adjust the filling volume, and the filling volume of all metering pumps can be adjusted at one time, and it can also be adjusted slightly for each metering pump. The piston sealing parts of the plunger metering pump is made of silicon rubber, tetrafluoroethylene, or other materials according to the industry and liquid composition, and ceramic material is used for special occasions.

If you want to fill olive oil products within 5L, the product type and specifications are less, and the filling accuracy requirement is relatively high, it is recommended to use a multi-head piston liquid filling machine.

The mobile filling heads viscous liquid filling machine is also a kind of piston filling machine, which occupies a smaller area than the ordinary multi-head piston filling machine, it greatly reduces the time for bottles to enter the conveyor belt and wait for filling, and the time required for each batch of bottles to be filled. The filling speed of the mobile four filling heads is the same as or faster than that of the ordinary 12 heads piston liquid filling machine (the filling speed is related to the bottle type and the material).

The mobile filling heads piston filling machine has the strongest compatibility with bottles and the most convenient adjustment. If you have several types of oils and the maximum filling capacity is 5L, and require the most convenient adjustment and high filling accuracy, we recommend that you can consider a mobile filling heads piston viscous liquid filling machine.

Under normal circumstances, for the same material and the same filling speed, the price of a flow meter viscous liquid filling machine is almost the same as that of an ordinary multi-head piston viscous liquid filling machine. The price of a mobile filling heads piston liquid filling machine is slightly more expensive than the flow meter’s viscous liquid filling machine by several thousand dollars.

The above three automatic viscous liquid filling machines can not only fill olive oil, but also fill viscous liquids in various industries, such as laundry detergent, engine oil, lubricating oil, edible oil, coconut oil, rapeseed oil, and sesame oil. , peanut oil, corn oil, etc. According to your liquid type, the range of filling volume, and the filling accuracy, a comprehensive analysis is required to see which type of liquid filling machine is best for you.
