“…Die holes differ in their length: diameter ratio, influencing the amount of shear that the feed mash receives. After leaving the die, pellets are usually cooled by air flow (136) . Despite the lower processing temperatures, the Maillard reaction occurs during pre-conditioning and/or pelleting, resulting in loss of reactive lysine and formation of MRP.…”

The Maillard reaction and pet food processing: effects on nutritive value and pet health

The Maillard reaction, which can occur during heat processing of pet foods or ingredients, is known to reduce the bioavailability of essential amino acids such as lysine due to the formation of early and advanced Maillard reaction products (MRP) that are unavailable for utilisation by the body. Determination of the difference between total and reactive lysine by chemical methods provides an indication of the amount of early MRP present in foods, feeds and ingredients. Previous research reported that the difference between total and reactive lysine in pet foods can be up to 61·8 %, and foods for growing dogs may be at risk of supplying less lysine than the animal may require. The endogenous analogues of advanced MRP, advanced glycation endproducts, have been associated with age-related diseases in humans, such as diabetes and impaired renal function. It is unknown to what extent advanced MRP are present in pet foods, and if dietary MRP can be associated with the development of diseases such as diabetes and impaired renal function in pet animals. Avoidance of ingredients with high levels of MRP and processing conditions known to favour the Maillard reaction may be useful strategies to prevent the formation of MRP in manufactured pet food. Future work should further focus on understanding the effects of ingredient choice and processing conditions on the formation of early and advanced MRP, and possible effects on animal health.

“…They have observed that the process of pre-compaction can increase the bulk density of raw material from 150 kg/m 3 to 270 kg/m 3 , which resulted in the continuous production of pellets at a moisture content of 13.8% (w.b.). Pressurized steam conditioners are used in the feed pellet industry to decrease raw material porosity and to improve pellet hardness/ durability (Thomas et al, 1997). Adapa et al (2010b) were unable to produce any pellets due to the low bulk density of both non-treated and pre-treated agricultural straw grinds at 10% moisture content (w.b.).…”

“…Steam-treated biomass is superior, as the additional heat modifies physiochemical properties (gelatinization of starch, denaturation of protein) to such an extent that binding between the particles is significantly enhanced, resulting in improved densification quality (Thomas et al 1997). Mani et al (2003) observed that moisture in the biomass during the densification process acts as a binder and increases the bonding via van der Waal's forces, thereby increasing the contact area of the particle.…”

It is generally acknowledged that burning fossil fuels and deforestation are major contributors to anthropogenic climate change. Biomass from plants can serve as an alternative renewable and carbon-neutral raw material for the production of energy. Low densities of 80-150 kg/m 3 for herbaceous and 150-200 kg/m 3 for woody biomass limit their application in energy production. Prior to cost-effective use in energy applications, these materials need to be densified to increase their bulk densities to help reduce technical limitations associated with storage, loading, and transportation. Pelleting, briquetting, or extrusion processing are methods commonly used to achieve densification. The aim of the present report is a comprehensive review of biomass processing, which includes densification technologies and specific energy consumption, biomass pretreatment methods, densification process modeling, and optimization. The specific objectives include:
