1. Introduction

Sugarcane is a widely cultivated plant with various beneficial components in its extracts. Bioavailability refers to the proportion of a drug or other substance which enters the circulation when introduced into the body and so is able to have an active effect. Understanding and optimizing the bioavailability of Sugarcane Extracts is crucial for harnessing their full potential in various applications such as in the field of nutrition, medicine, and cosmetics.

2. Factors Affecting Bioavailability of Sugarcane Extracts

2.1 Extraction Techniques

Different extraction methods can significantly impact the bioavailability of Sugarcane Extracts.

• Solvent Extraction: Using solvents like water or ethanol to extract components from sugarcane. The choice of solvent can influence the type and quantity of compounds extracted. For example, water extraction may be more suitable for polar compounds, while ethanol can extract a wider range of both polar and non - polar substances. However, improper solvent extraction may lead to the degradation of some active compounds, reducing their bioavailability.
• Pressurized Liquid Extraction: This method uses high pressure and temperature to extract compounds. It can enhance the extraction efficiency of certain bioactive components. But if the parameters (such as pressure and temperature) are not properly controlled, it may also cause the denaturation of some proteins or other heat - sensitive compounds, thus affecting bioavailability.
• Supercritical Fluid Extraction: Supercritical carbon dioxide is often used in this method. It has the advantages of being non - toxic, non - flammable, and having a relatively low critical temperature. This method can selectively extract specific compounds from sugarcane with high purity. However, the equipment for supercritical fluid extraction is relatively expensive, which may limit its widespread application in optimizing bioavailability on a large scale.

2.2 Compound Properties

The chemical and physical properties of the compounds in sugarcane extracts play a vital role in their bioavailability.

• Molecular Size and Structure: Larger molecules may have difficulty passing through biological membranes, thereby reducing their absorption and bioavailability. For example, some polysaccharides in sugarcane with complex and large molecular structures may need to be broken down into smaller units (such as oligosaccharides) to be more easily absorbed by the body.
• Solubility: Compounds that are more soluble in the body's fluids (such as water - soluble vitamins in sugarcane extracts) are generally more easily absorbed. In contrast, hydrophobic compounds may require special mechanisms (such as being incorporated into micelles) for absorption. For instance, some lipid - soluble antioxidants in sugarcane may need to be emulsified to improve their solubility and bioavailability.
• Stability: The stability of compounds in different physiological environments also affects bioavailability. Some compounds may be unstable in the acidic environment of the stomach or in the presence of certain enzymes. For example, certain phenolic compounds in sugarcane extracts may be oxidized or degraded before they can be fully absorbed, thus reducing their bioavailability.

2.3 Biological Processes

• Digestion and Absorption: In the digestive system, sugarcane extracts are subjected to various enzymatic reactions. For example, carbohydrases can break down carbohydrates in the extracts, and proteases can act on any proteinaceous components. The products of these enzymatic reactions need to be absorbed through the intestinal epithelium. The integrity and function of the intestinal epithelium are crucial for bioavailability. Any damage or malfunction of the epithelium can lead to reduced absorption of the beneficial compounds in sugarcane extracts.
• Metabolism: Once absorbed, the compounds in sugarcane extracts may be metabolized in the body. Some compounds may be converted into more active forms, while others may be metabolized into inactive metabolites. For example, some flavonoids in sugarcane may be methylated or glucuronidated in the liver, which can either enhance or reduce their biological activity and bioavailability depending on the specific metabolic pathway.
• Distribution: After absorption and metabolism, the compounds are distributed throughout the body via the bloodstream. Their distribution is affected by factors such as their affinity for different tissues and their ability to cross biological barriers. For example, some compounds may have a higher affinity for adipose tissue, while others may be preferentially distributed to the liver or kidneys.

3. Strategies to Enhance Bioavailability

3.1 Modifying Extraction Processes

1. Optimizing solvent extraction: By carefully selecting the solvent type, ratio, and extraction time, the extraction of bioactive compounds can be maximized while minimizing degradation. For example, a combination of water and a small amount of ethanol may be used to extract a broader range of compounds with higher bioactivity.
2. Using novel extraction techniques: Research into new extraction methods such as microwave - assisted extraction or ultrasound - assisted extraction can improve extraction efficiency and preserve the bioactivity of compounds. These techniques can reduce extraction time and energy consumption compared to traditional methods, and may also enhance the bioavailability of the extracted compounds.
3. Pre - treatment of sugarcane: Before extraction, pre - treating sugarcane, such as by enzymatic hydrolysis or physical disruption (e.g., grinding or milling), can increase the accessibility of the internal components, leading to more efficient extraction and potentially higher bioavailability of the extracts.

3.2 Formulation and Delivery Systems

• Encapsulation: Encapsulating sugarcane extracts in nanoparticles or microcapsules can protect the active compounds from degradation in the gastrointestinal tract and improve their solubility. For example, lipid - based encapsulation can enhance the delivery of hydrophobic compounds in sugarcane extracts, increasing their bioavailability.
• Complexation: Forming complexes with other substances can also improve bioavailability. For instance, some metal ions can form complexes with certain polyphenols in sugarcane extracts, which may enhance their stability and absorption in the body.
• Use of Carrier Agents: Carrier agents such as cyclodextrins can be used to improve the solubility and stability of compounds in sugarcane extracts. Cyclodextrins can form inclusion complexes with hydrophobic molecules, making them more water - soluble and thus more easily absorbed.

3.3 Dietary and Lifestyle Considerations

• Combination with Other Foods: Consuming sugarcane extracts in combination with certain foods can enhance their bioavailability. For example, consuming sugarcane - based products with foods rich in healthy fats can improve the absorption of lipid - soluble compounds in the extracts. Similarly, consuming them with foods high in fiber can slow down digestion and increase the contact time of the extracts with the intestinal epithelium, facilitating absorption.
• Timing of Consumption: The time at which sugarcane extracts are consumed can also affect bioavailability. For example, consuming them on an empty stomach may result in faster absorption for some compounds, while consuming them with a meal may lead to different absorption kinetics depending on the composition of the meal.
• Physical Activity: Regular physical activity can improve blood circulation and the function of the digestive system, which may indirectly enhance the bioavailability of sugarcane extracts. Exercise can increase the perfusion of the intestines and the transport of nutrients across the intestinal barrier.

4. Applications of Optimized Bioavailability of Sugarcane Extracts

4.1 Nutritional Supplements

Optimized bioavailability of sugarcane extracts can lead to more effective nutritional supplements. For example, sugarcane contains vitamins (such as vitamin C and some B - vitamins), minerals, and bioactive compounds like polyphenols and flavonoids. When these extracts have high bioavailability, they can better meet the nutritional needs of individuals. They can be used to supplement the diet of people with specific nutritional deficiencies or those who are at risk of developing certain diseases due to poor nutrition.
