Comparison between cold pressed oil and hot pressed oil

In our daily life, we are faced with two kinds of edible oil production, they are cold pressed oil and hot pressed oil. While there exist great differences between them. Firstly , the production process is different.

As for hot pressing oil, the high-temperature processing has lead to high oil yield. Whereas the color is deeper with the thick bean smell. According to the process, it contains crude soybean oil, filtered soybean oil, refined soybean oil. Crude soybean oil is tawny, whereas most of the refined soybean oil is yellowish with large stickiness.

Understanding The Difference: Rapeseed Oil VS. Cold-Pressed

How we cold-press oil. The process of cold- pressing oil is actually incredibly simple. The process of no process if you will! Our rapeseed presses are like large screws which cold press the seeds by squeezing the oil gently from them. The seed is added to the press and the oil is crushed/pressed out of the seeds. No heat or chemicals are applied.

Cold Press Oil Machine

A cold press oil expeller is a machine designed to extract oil from seeds and nuts without the application of heat. Key Features1.Cold Pressing Process: Unlike traditional oil extraction methods that use heat, cold pressing involves crushing the seeds or nuts at low temperatures.

Cold-pressed oils, also known as “expeller-pressed” or “mechanically pressed” oils, are extracted using mechanical pressing methods without applying heat. The term “cold” is used because the pressing occurs below 120°F (49°C), ensuring the oil retains its natural nutrients, flavor, and aroma.

Oil Expeller Machine, Cold Press Oil Expeller Machine

Domestic Wooden Cold Press Oil Machine, a robust and elegant device with a capacity of 20 kg/hr, perfect for home and small-scale production. Crafted with high-quality wood, this machine combines traditional aesthetics with modern efficiency, extracting pure and nutritious oil from a wide range of oilseeds, including sunflower, sesame, flax, and more.

Soybean is the most commonly produced oil crop in the world. Soybean oil is primarily used in the production of shortenings, margarines, cooking/frying oils, salad dressings, and mayonnaise. Due to the lower oil content (~ 20%) of soybean, its oil is mostly recovered by solvent extraction. Hence, mechanically pressed soybean oil comprises a

Are cold pressed soybean oils solvent-extracted?
Commercial soybean oils are commonly solvent-extracted and refined due to their high phosphatides contents. Hence, few studies exist on characterization of cold pressed soybean oils in the literature.
Is cold pressed soybean oil linoleic?
One of these studies revealed that cold pressed soybean oil consists of linoleic (50.8%), oleic (24.6%), palmitic (10.2%), linolenic (7.6%), stearic (3.7%), and vaccenic (1.5%) acids, and trace amounts of myristic, palmitoleic, heptadecanoic, arachidic, eicosenoic, behenic, erucic, and lignoceric acids ( Tuberoso et al., 2007 ).
Does cold pressed soybean oil contain trans fatty acids?
However, Brühl (1996) detected the presence of trans fatty acids (0.10%¨C0.15%) in cold pressed soybean oils. The author thus stated that trans fatty acids may occur due to high temperature drying of seeds before cold pressing and/or deodorization of cold pressed soybean oils or blending of cold pressed oils with refined ones.
How much phytosterol is in cold pressed soybean oil?
It is reported that the total phytosterol content of cold pressed soybean oil (3.2 mg/g) is close to that of cold pressed flaxseed (3.1 mg/g), and sunflower (3.2 mg/g) oils, and less than that of cold pressed corn (9.7 mg/g), and rapeseed (7.7 mg/g) oils ( Rudzi¨½ska et al., 2001 ).
Why is cold pressed soybean oil a limiting factor?
However, the cold pressing technique does not allow to use high temperature processes, so that enzyme activity maintains in cold pressed soybean oils. This is the essential limiting factor for use of the cold pressing method in soybean oils. 3. Fatty acids and acyl lipids
Does cold pressed soybean oil scavenge radicals?
On the contrary, cold pressed soybean oil was characterized by remarkably lower 2,2-diphenyl-1-picrylhydrazyl (DPPH·) radical scavenging activity (17.4%) than cold pressed oils of hemp (76.2%), pumpkin seed (65.3%), rapeseed (51.2%), sunflower (23.8%), rice bran (23.7%), and flaxseed (19.3%) ( Siger et al., 2008 ).
