Summary
Hemp seed oil oleogels can replace margarine in cookies, reducing saturated fat and improving health. These oleogels enhanced cookie dough consistency and hardness, with the beeswax variant being most preferred by consumers.
Area of Science:
- Food Science
- Rheology
- Material Science
Background:
- Margarine in cookies contributes to saturated fat content.
- Oleogels offer a potential healthier alternative to traditional fats.
- Hemp seed oil is a viable base for oleogel development.
Purpose of the Study:
- To evaluate hemp seed oil oleogels as margarine substitutes in cookies.
- To analyze the rheological and textural properties of oleogel-based cookie dough.
- To assess the sensory attributes, texture, and color of the final cookie products.
Main Methods:
- Oleogelation of hemp seed oil using various waxes (beeswax, carnauba wax, candelilla wax, rice bran wax) and agents (sitosterol, pea protein, xanthan gum).
- Rheological analysis using a Haake rheometer to determine elastic (G') and viscous (G″) components.
- Textural analysis using a PertenTVT-6700 texturometer to measure dough and cookie hardness.
- Sensory evaluation and colorimetric analysis of formulated cookies.
Main Results:
- Oleogels increased cookie dough hardness and consistency, with sitosterol oleogel showing the highest hardness.
- Elastic (G') and viscous (G″) components of the dough increased, indicating altered rheological behavior.
- Cookies formulated with hemp seed oil and beeswax oleogel received the highest sensory ratings.
- Oleogel cookies exhibited darker coloration compared to the control.
Conclusions:
- Hemp seed oil oleogels are effective fat substitutes in cookie formulations.
- Oleogel incorporation impacts dough rheology, texture, and color.
- The beeswax-based hemp seed oil oleogel shows promise for healthier cookie production.

01:15Sensory Modalities
Sensation typically is the process by which the sensory receptors and sense organs detect stimuli from the internal and external environment and transmit this information to the central nervous system for processing.
General senses refer to the broad category of sensory information detected by receptors in the body and can be further grouped into somatic and visceral senses. Somatic sensations include touch, pressure, temperature, and pain and are essential for navigating our environment and...

01:20Taste Buds and Receptors
Gustation, or the sense of taste, is intrinsically linked to the anatomical structures located on the tongue. This organ's surface, along with the entirety of the oral cavity, is adorned with stratified squamous epithelium. Evident on the tongue are elevated structures known as papillae (singular = papilla), which house the mechanisms for the transduction of gustatory stimuli. Four distinct types of papillae exist, each identified by their unique morphological attributes: the circumvallate,...
01:29Strength and Heat of Hydration
The hydration of cement is an exothermic reaction in which heat is generated as cement hydrates. This heat of hydration is critical to cement's strength development. The rate at which this heat is generated affects the temperature rise, with a majority of the heat being released early in the hydration process, half within the first three days, and about 75% within the first week.
The heat of hydration for each cement compound is significant; for instance, tricalcium aluminate (C3A) and...
