Reduced-Fat Product Development Guide

The challenge of fat reduction

Besides carrying flavour, fat provides juiciness, softness, a creamy mouthfeel and texture in foods. When fat is reduced these functions are lost and the product can become dry, hard or watery and bland. A successful fat reduction project requires replacing the removed fat with ingredients that bind water and support texture.

Fibres: filling the gap with water

The most common approach to fat reduction is to replace part of the removed fat with water and bind that water with fibres. Citrus fibre gives a creamy mouthfeel through its high water- and fat-binding capacity and is widely used in sauces and meat products. Pea fibre and wheat fibre increase juiciness and cooking yield in meat products. Cellulose fibre provides volume and structure in bakery.

Starch: body and creaminess

In reduced-fat mayonnaise, sauces and creams, starch compensates for the body provided by fat. Modified starches resist acid, heat and shear; rice starch, with its small granules, gives a creamy, fat-like mouthfeel. Using starch and fibre together gives a more natural texture.

Protein: emulsion and structure

Pea protein stabilises oil droplets in low-fat emulsions and supports texture in meat products through water and fat binding. Egg yolk powder maintains emulsifying power in light mayonnaise. Transglutaminase can improve texture in reduced-fat meat products by strengthening the protein network.

Compensating for flavour

Because fat carries flavour compounds, flavour perception weakens and changes when fat is reduced. Spices, especially intensely aromatic ones such as onion powder, garlic powder, black pepper and thyme, help boost flavour intensity. Salt and acid balance should also be readjusted.

Application examples

In reduced-fat meatballs, part of the fat can be replaced with water and 1-2% pea or citrus fibre. In light mayonnaise, as oil is reduced, body is maintained with modified starch and citrus fibre and emulsion with egg yolk powder. In cakes, part of the fat can be replaced with citrus fibre and water for a moist texture.

Nutrition claims

A "reduced fat" claim requires fat content at least 30% lower than a similar product, and a "low fat" claim requires no more than 3 g of fat per 100 g for solid foods. Claims must be used in line with regulations and verified by analysis.
