Strategies to Improve Textural Quality in Low-Fat Meat Products

Emulsified cooked meat products such as bologna, nuggets and sausages are produced from comminuted or finely homogenized meat14. They generally contain high saturated fats from animal sources that are linked with increased prevalence of cardiovascular diseases, cancer, and obesity around the world7,10.

Fat reduction is a big challenge in the meat industry as ensuring the texture is succulent and flavourful is important. When the fat content is reduced, the meat products tend to be firmer, rubbery, and less juicy1,4. Hence, there have been many strategies explored by the meat industry for reducing fat content while retaining its desirable sensory and textural attributes7.

The challenges can be remediated through water-binding ingredients like inulin and rice starches.

Inulin

Inulin is a soluble dietary fiber extracted from chicory roots, that possesses excellent properties as a carbohydrate-based fat substitute.  With its ability to form a stable gel network and great water holding capacity, inulin can be used to mimic some textural properties of fat and contributes a smooth, creamier, juicier mouthfeel in low-fat formulations and provides good source of dietary fiber12. It also successfully enhances emulsion stabilisation and cooking yield2,8. In addition, inulin remains stable without a significant loss of physical, chemical, microbiological, or sensory attributes during storage in dry-fermented products11.

Specialty Rice Ingredients

Starches are commonly used as water absorbents and binding agents in sausages or other processed meat as they retain moisture throughout product processing and storage, and stabilize the emulsion of moisture, fat, and protein13. Starch possesses a thickening effect when the native starch granules swell during heating, leading to a large increase in viscosity6. The small size of rice starch granules and the wide range of amylose content of rice varieties provide opportunities used as fat mimetics in various food items. Waxy rice starch exhibits good water binding performance at a low temperature of about 70–80 °C. This makes it the perfect clean label ingredient to control the yield and juiciness of meat3,15. Besides, experimental results suggest that texture and sensory evaluation of ground pork patties are improved by adding glutinous rice flour5 while modified broken rice can be used as a fat substitute (55% fat reduction) in sausage formulations, yielding lower caloric value products and increasing the texture acceptability of low-fat sausages9.

Conclusion,

Tenderness is regarded to be the most crucial sensory characteristic of meat. Inulin and rice ingredients can be considered a viable method that resembles the sensory and textural attributes of animal fat when formulating healthier meat products. At DPO, we are honored to have a partnership with Beneo Orafti and Beneo Remy to bring you a wide range of ingredient choices that will elevate the quality of your meat and seafood products.
