Bitter vs. Sweet Almond Oil: How Are They Different?

Almond oil encompasses oils extracted from both bitter and sweet almonds, making it a broad category in the world of oils. On the flip side, sweet almond oil specifically comes from the sweet variety of almonds, distinguishing itself as a specialized subset within the almond oil family.

Commonly, the phrase ‘almond oil’ tends to point towards sweet almond oil, celebrated for its wide-ranging applications and popularity. This variety frequently stars in culinary creations and skincare formulations, indicating that ‘almond oil’ typically implies the sweet kind.

Yet, a surprising number of people remain unaware that almond oil also spans the bitter type, which sees less usage due to its potential toxicity. Recognizing the nuances between these oils is crucial to ensure the correct usage and to sidestep any confusion.

What is almond oil?

Picture this: a bottle of almond oil and its seeds sketched with care. Almond oil is derived from the kernels of the Prunus dulcis tree, rooted in the soils of Southwest Asia and the Middle East, stretching to the banks of Pakistan’s Indus River. Almonds, often mistaken for nuts, are in fact drupes—seeds encased in a hard shell surrounded by a fleshy outer layer. These versatile seeds are consumed whole, ground into flour, transformed into non-dairy milk, and pressed for their oil, making them a cornerstone in both the food and cosmetic industries.

Boasting a spectrum of health benefits, almond oil is a prized ingredient in skincare and haircare products, as well as a revered substance in Ayurvedic medicine for its therapeutic properties. Beyond the conventional, almond oil has emerged as a potential renewable biofuel, with studies suggesting its efficacy in diabetes and cancer prevention. Remarkably, its advantages extend to the animal kingdom, offering benefits to pets as well.

Renowned for its adaptability, almond oil plays pivotal roles beyond nutrition and health, making significant contributions to aromatherapy among other uses. Continue reading to dive deeper into the essence of almond oil, including its varieties, production methods, and the plethora of benefits it brings to the table.

Almond oil varieties

Almonds, abundant in fat content, serve as an excellent reservoir for oil extraction. They exist in two primary forms: sweet almonds, the more prevalent in consumption, and bitter almonds.

Sweet Almond Oil

Derived from the sweet almonds of the Prunus dulcis tree, var. amygdalus, this oil finds extensive use in home remedies and cosmetics. Sweet almonds, distinguishable by their predominantly white blossoms, offer not only nutritional value but also versatility in culinary applications. Rich in vitamin E and omega-6 fatty acids, sweet almond oil is prized for its benefits to health, skin, and hair. Serving as a base oil, it complements various cosmetic formulations and dilutes essential oils effectively without overpowering aromas.

Bitter Almond Oil

Extracted from the bitter almonds of the Prunus dulcis tree, var. amara, this oil boasts high potency but requires cautious application due to its toxic properties if improperly handled. The pink blooms of the tree differentiate it from its sweet counterpart, and the almonds themselves are notably shorter and wider. Bitter almond oil, an essential oil, possesses a concentrated aroma and rapid evaporation, rendering it unsuitable for direct skin care usage. Despite its toxicity, it finds utility in medicinal contexts, valued for its anti-carcinogenic properties and application in aromatherapy.

How to tell between Sweet and Bitter Almond Oil?

The primary divergence lies in their nature: sweet almond oil is a fixed oil, while bitter almond oil functions as an essential oil. This contrast extends to their uses and chemical compositions.

Discerning between the two is feasible. Sweet almond oil typically comes in larger plastic bottles, owing to its versatility and lower potency. Conversely, bitter almond oil, with its propensity to degrade plastic and swift evaporation upon light exposure, is packaged in smaller, dark glass bottles.

Virgin, Refined, and Unrefined Almond Oil

The extraction process of almond oil involves either mechanical or chemical means, leading to distinctions in quality known as virgin, refined, and organic. Similar to other oils, almonds undergo either solvent extraction or pressing for oil extraction.

Refined almond oil

Obtained through solvent extraction involving chemical agents and high temperatures, refined almond oil yields the highest industrial output. However, this method compromises the oil’s quality by introducing undesirable flavors and deactivating essential vitamins and active compounds present in raw oil. Alternatively, refining can occur through filtration or distillation after pressing, resulting in purified oil devoid of its natural aroma and taste.

Virgin almond oil

Virgin almond oil, derived primarily through cold pressing methods, represents the unrefined variant, also known as “virgin” or “extra virgin.” These designations denote varying grades of oil quality according to industry standards. Extra virgin oil, the highest grade, must meet stringent chemical and sensory criteria. Manufacturers can only label their product as “virgin” or “extra virgin” when they meticulously document the extraction and packaging processes.

Organic almond oil

Another term encountered in the market is organic almond oil, denoting certification from an authoritative body. This certification ensures that the almond source has not been subjected to pesticides, and the final product remains free from chemical contamination.

Is any of the two types of almonds poisonous?

The bitter variety of almonds harbors a toxic substance capable of releasing hydrogen cyanide, rendering them highly poisonous in their raw state. This perilous characteristic underscores the caution necessary when foraging almonds from the wild; not every almond tree bears safe fruit. Merely 100-200 mg of hydrogen cyanide can swiftly lead to fatal consequences for the consumer, with a single raw bitter almond releasing approximately 4-9 mg of this deadly compound upon ingestion.

Thus, even a small handful of raw bitter almonds holds the potential to cause swift and severe harm, including kidney failure, to those who consume them. Recognizing this danger, numerous countries, including the US, have implemented bans on the sale of raw bitter almonds. Despite their inherent peril, bitter almonds can be rendered safe through proper processing, during which hydrogen cyanide is effectively eliminated through heating or baking. However, it remains imperative for individuals to exercise extreme caution and refrain from consuming bitter almonds altogether.

Distinguishing between bitter and sweet almonds can be challenging, as they share similar appearances aside from the bitter variety’s slightly smaller and more pointed shape. Fortunately, the almonds typically found in grocery stores are of the sweet variety, posing minimal risk of cyanide exposure. Similarly, sweet almond oil, commonly available on supermarket shelves, presents no such danger and is safe for consumption and external application.

Although less readily accessible in stores, bitter almond oil should never be utilized without expert guidance and should never be applied directly to the skin or ingested due to its inherent toxicity.

How is almond oil extracted?

Almond oil extraction employs two primary methods: solvent extraction and pressing, each with distinct advantages and drawbacks.

Solvent extraction

This method relies on chemical agents and elevated temperatures to extract oil from almonds. While it yields the highest industrial output, it compromises oil quality by introducing undesirable compounds. Additionally, solvent extraction necessitates oil refinement to eliminate undesirable substances present in the raw material.

Extraction through pressure

Utilizing hydraulic and screw presses, this method offers superior retention of the oil’s physicochemical and sensory properties, particularly with hydraulic presses. However, its labor-intensive nature diminishes profitability. The cold pressing system, often executed with screw presses, is currently the most widespread method. Despite its designation, preheating is required for optimal volume extraction, albeit at the expense of oil quality.

Extracting almond oil at home

Producing almond oil at home proves simple and cost-effective, circumventing the need for specialized equipment. Follow these straightforward steps:

  1. Begin with fresh, dry almonds and place them in a clean blender.
  2. Initiate blending at low speed, allowing the almonds to form a ball and accumulate along the blender’s sides.
  3. Periodically halt blending to scrape off any buildup and resume until the almonds become mushy.
  4. Increase the blender speed to medium or higher once the almonds achieve a creamy consistency.
  5. Introduce a teaspoon of olive oil and continue blending until a rich paste forms.
  6. Transfer the mixture into a glass jar or airtight container and store at room temperature for approximately two weeks.
  7. After the designated period, the oil will naturally separate from the mixture.
  8. Strain the oil into a separate container using a fine sieve or strainer.

This homemade almond oil is suitable for skincare and aromatherapy purposes, offering a natural and accessible alternative to commercial products.

What constitutes sweet almond oil?

Sweet almond oil is rich in a variety of chemical components, including fatty acids, phytosterols, and tocopherols. Its primary constituent is oleic acid, a monounsaturated fatty acid, accounting for 65-75% of its composition. Other notable fatty acids include linoleic acid (13-25%) and saturated fats such as palmitic and stearic acid (8-10%). β-sitosterol dominates the sterol composition (75-85%), complemented by an abundance of α-tocopherol (vitamin E).

Monounsaturated oleic acid

Numerous studies have demonstrated the cholesterol-lowering effects of oleic acid, particularly in reducing Low-Density Lipoprotein (LDL) cholesterol, commonly referred to as “bad cholesterol.” Elevated LDL levels correlate with increased risk of heart disease, making the reduction of these levels crucial for mitigating such risks. Additionally, monounsaturated oleic acid contributes to blood pressure regulation, improved insulin sensitivity, and weight management.
