What are the factors that contribute to the absorption of oil during frying?

Contents show

The higher the initial moisture content and smaller the particle size, the higher the final oil content. The pore size distribution and/or air mass that occurs during frying results in higher oil content due to higher capillary pressure in the pores during cooling.

What limits fat absorption during frying?

Soy protein isolate (SPI), whey protein isolate (WPI), and methyl cellulose (MC) have been the best coating materials for reducing fat uptake during frying.

How does frying temperature affect absorption of fat?

Frying temperature is a factor that limits fat absorption in fried foods. The optimum temperature depends on the ingredients, but ranges from 160-180°C. The lower the temperature, the more fat absorbed; the higher the temperature, the less oil is absorbed and the crispier the food, but the risk of burning the surface is higher.

What happens to oil during frying?

Oil hydrolysis, oxidation, and polymerization are common chemical reactions in frying oils that produce volatile or nonvolatile compounds. Most of the volatile compounds evaporate into the atmosphere with water vapor, while the remaining volatile compounds in the oil can undergo further chemical reactions or be absorbed into the fried food.

What reduces fat absorption when frying foods?

When battering food prior to frying, use a carbonated liquid, a small amount of an expander (baking soda), or both in the batter. These release air bubbles as the food cooks, further reducing oil absorption.

What absorbs oil in cooking?

Breading or coating snacks with other foods such as bread crumbs, wheat flour, or oats may cause the flattened rice to absorb more oil and swell calories. If you want to reduce oil absorption in fritters and snacks, coat the snacks with a thin batter of flour, rice flour, or cornflour.

How much oil is absorbed when you fry something?

Fried at room temperature, fritters absorb 8-25% oil. Lower temperatures increase frying time. Frying at lower temperatures results in lighter color, less flavor development, and increased oil absorption. Deep frying at higher temperatures results in a thinner crust and less oil absorption.

What happens during frying?

The Maillard reaction occurs during the frying process, resulting in a golden color and rich flavor. The heat of the oil also cooks the interior of the food, softening the fibers, denaturing the proteins, and gluing the starches.
