Marine and freshwater fish harbour an intestinal microbiota less abundant than in mammals, made of aerobic and facultative anaerobic bacteria. Limited and conflicting data have shown either the complete lack of cellulose degradation in the trout or tilapia, or a limited (13%) activity in the trout. A digestibility study carried out in the trout and the carp administered a purified (devoid of lignin and reduced amount of hemicelluloses) crystalline cellulose extracted from wood (fibre length ˂ 150 μm, diameter ˂ 45 μm), showed the practical absence of cellulose degradation in both species (Bergot and Breque, 1983).

In the rabbit hindgut, fermentation occurs through a wide prevalence of Bacteroides that do not allow an extended digestibility of fibre. Digestibility of cellulose was shown to amount to 16% of the administered dose, whereas values of 14% and 18% were reported for fibre (cellulose being the main component) (review from the NRC, 1977). Later studies reported values comprised between 15 and 25% in rabbits administered different plant sources of cellulose (Gidenne and Perez, 1996; Chiou et al., 1998). In the horse, digestion of plant structural carbohydrates (including cellulose) occurs in the hindgut (colon and overall caecum). The microbiota of the caecum comprises bacteria similar to those of the rumen, but specific protozoa. The resulting digestibility is about two-third that measured in ruminants.

- Introduction
- liquid formulations such as suspensions and emulsions
- One of the key properties of HPMC is its ability to form gels in water. This makes it an excellent choice for thickening liquids, such as sauces, soups, and cosmetics. When HPMC is added to a liquid, it absorbs water and swells, creating a gel-like texture. The thickness and viscosity of the gel can be adjusted by varying the concentration of HPMC in the liquid.
- In the food industry, HPMC is used as a thickening agent, stabilizer, and emulsifier in a wide range of products, including sauces, dressings, and desserts. The viscosity of HPMC can be adjusted to achieve the desired texture and mouthfeel, making it a versatile ingredient for food manufacturers.
- Understanding the solubility of HEC in ethanol is critical for applications where controlled release, viscosity modification, or film formation is required, such as in the pharmaceutical, paint, and coating industries. It allows for precise formulation design and process optimization, ensuring optimal product performance and stability.
- One notable application of MHEC is in the formulation of tablets for the pharmaceutical industry
Answer: The main raw materials of hydroxypropyl methyl cellulose (HPMC) : refined cotton, chloromethane, propylene oxide, other raw materials and alkali tablets, acid, toluene, isopropyl alcohol and so on.
- 2. Microbial Contamination HPMC may serve as a nutrient source for microorganisms, leading to the growth of bacteria, fungi, or other contaminants. Therefore, manufacturers must implement effective sanitation and sterilization procedures to prevent microbial contamination.
- Environmentally, redispersible powder polymers offer benefits as well.
