Origin

Fats can be derived from both animal and plant sources. Lard extraction from pig fat via boiling in water and skimming off is a very ancient practice. Butter is traditionally prepared from milk cream churning. Concerns about high cholesterol content of animal-sourced fats created the need for solidifying vegetable oils using hydrogenation.3

Function4

In bakery products, fat serves many functions:

  • Flavor enhancer: this is most pronounced with animal-based fats, which impart richness and unique flavor notes.
  • Texture: mainly reduced toughness and enhanced tenderness.
  • Moistness and mouthfeel: via coating the tongue and eliminating food surface grittiness.
  • Leavening: via incorporating air during creaming and baking.
  • Delayed staling: a result of fat’s interference with starch gelatinization.

These functions are typically dependent on fats’ inherent characteristics such as:

  • Plasticity: an important attribute for shortenings.
  • Ratio of solid:liquid content: the higher the solid content the higher the fat melting point.
  • Oxidative stability: unsaturated fats are readily oxidized and hydrogenation has been used to enhance their oxidative stability. Generation of trans fat, however, is a major drawback for hydrogenation

Types/Variations4

  • Lard: contains 100% fat and is obtained from hog fat
  • Shortening: is made from hydrogenated soybean oil or other vegetable sources. Consist of 100% fat.
  • Oils: are liquid fats obtained from seeds such as soybean, corn or cottonseed. They contain 100% fat.
  • Butter: contains 80% fat and 20% water and is made from churning cream. It is available commercially in the salted or unsalted varieties.
  • Clarified Butter: is butter that has been heated to remove the milk solids sediments to form a clear color.
  • Margarine: is made from hydrogenated soybean oil or other vegetable sources. Consists of 80% vegetable fat and 20% water.
  • Cocoa Butter: is extracted from cocoa beans.

Nutrition

Lipids are energy dense nutrients (9 kcal/g). Most polyunsaturated fatty acids including omega-3 and similar structures are essential for many biological functions. However, concerns remain with animal-based fats due to their high cholesterol content. Also hydrogenated oils can be a source of harmful trans-fatty acids.2

Commercial production2

The following diagram describes the process of vegetable oil extraction and making of shortening:

Application

Categorization of fats is based on their:2

  • Physical form: solids and semisolids (lard, butter, shortening) or liquids (oils).
  • Chemical composition: type and length of fatty acid chains, degree of saturation.
  • Solubility: fats are insoluble in water but soluble in organic solvents.

Fats such as butter, shortenings or hydrogenated fats are typically used in bakery goods including cakes, puff pastry, breads, cookies, scones, pie crusts.1,4

In puff pastry such as croissants, butter is responsible for their desirable flaky texture. As the butter laminated dough enters the hot oven, the water component in the butter evaporates and the generated steam causes the dough to rise.

In cookies, fats are typically creamed with sugar, thus providing for their chewy texture. In cakes, fats can either be creamed with sugar to act as a leavening agent or are added as such to promote moistness and soft texture. In breads, fats act as dough lubricants which help with loaf rise and crumb softening.

FDA regulations

Fats are considered GRAS ingredients. However, since 2015 the consumption of trans fats such as partially hydrogenated oils (PHO’s) are no longer considered safe by the FDA. The consumption of saturated fats has a recommended consumption limit of 10 % calories per day.5

FAQs

What are the ingredients of fat? ›

Fats and oils are organic compounds that, like carbohydrates, are composed of the elements carbon (C), hydrogen (H), and oxygen (O), arranged to form molecules.

What are the fat ingredients in baking? ›

What does fat mean in ingredients? ›

In nutrition, biology, and chemistry, fat usually means any ester of fatty acids, or a mixture of such compounds, most commonly those that occur in living beings or in food. Idealized representation of a molecule of a typical triglyceride, the main type of fat.

What does fat do in baking cookies? ›

The molecules of fat surround the flour particles and exclude water. This prevents the development of gluten in the dough. The fat is said to shorten the dough. Any increase in water in the mixture will tend to encourage development of gluten, which will make biscuits hard and pastry heavy.

What are the 3 main sources of fat? ›

Sources of dietary fat

fatty cuts of meat. full-fat milk, cheese, butter, cream. most commercially baked products (such as biscuits and pastries)

What are the healthiest fats to eat? ›

Choose foods with “good” unsaturated fats, limit foods high in saturated fat, and avoid “bad” trans fat. “Good” unsaturated fats — Monounsaturated and polyunsaturated fats — lower disease risk. Foods high in good fats include vegetable oils (such as olive, canola, sunflower, soy, and corn), nuts, seeds, and fish.

What is the healthiest fat to bake with? ›

The recipes are low in natural sugars and made from wholesome ingredients that make you feel great inside out. My favourite fats for baking and raw desserts are extra virgin olive oil, grass fed butter or ghee, macadamia nut oil, cold-pressed coconut oil and avocado oil.

What is the best fat for baking? ›

Butter is the favoured fat to use in cakes and bakes and we use unsalted butter for all of our cakes in the bakeries. It is made from churned cream, a process that separates the butterfat from the buttermilk. It is typically made from cow's milk and is yellow in colour.

What are bad fats? ›

Two types of fats — saturated fat and trans fat — have been identified as potentially harmful to your health. Most of the foods that contain these types of fats are solid at room temperature, such as: butter.

Which fat is bad for cholesterol? ›

Saturated fat tends to raise levels of cholesterol in the blood. Low-density lipoprotein (LDL) is called "bad" cholesterol. High-density lipoprotein (HDL) is called "good" cholesterol. Saturated fats raise the levels of both.

What are other names for fat in an ingredient list? ›

Common names for fat added to foods are butter, coconut cream, cream, hydrogenated vegetable fat, lard, margarine, oil, trans fats, triglycerides and vegetable oil. Read the labels on the food in your pantry before you head out to the supermarket.

What is the fat ingredient in cookies? ›

Fat is added for flavor and controls how chewy or crunchy the cookie is. More fat = a chewier cookie, less fat = a crunchier cookie. Your options for fat are butter, margarine, shortening, or oil. Since shortening melts at a higher temperature, it is the best choice if you want to keep spreading to a minimum.

What is the rule of fat in baking? ›

In baked goods, fat also contributes to the tenderness of a product as it prevents flour from absorbing water. Muffins or biscuits with reduced fat are often tougher because the gluten is more developed. One method to counteract the toughness is increased sugar. Fat can also work as a leavening agent.

What is total fat made up of? ›

Fats provide essential fatty acids necessary for health and allow us to absorb the fat-soluble vitamins A, D, E, and K. This article examines the 4 major types of fat: saturated, trans fats, unsaturated, and monounsaturated. When we refer to "total fat," we mean the sum of all 4 of these.

What does human fat contain? ›

Body fat is primarily known for storing and releasing energy and providing insulation. However, scientists now recognize that it's also an active organ in your endocrine system. Adipose tissue contains nerve cells and blood vessels and communicates through hormone signals with other organs throughout your body.

What are the two chemical ingredients in fats? ›

A fat molecule consists of two kinds of parts: a glycerol backbone and three fatty acid tails. Glycerol is a small organic molecule with three hydroxyl (OH) groups, while a fatty acid consists of a long hydrocarbon chain attached to a carboxyl group.
