Answers

To determine the fructose content in peas, several laboratory tests can be employed. Here are a few common methods used to analyze carbohydrate content, including fructose:
1. **High-Performance Liquid Chromatography (HPLC)**: This method separates, identifies, and quantifies the various sugars present in a sample. By comparing the peak areas to those of known standards, the fructose content can be accurately measured.
2. **Gas Chromatography (GC)**: After converting sugars into volatile derivatives, GC can be used to separate and quantify fructose and other sugars.
3. **Enzymatic Assays**: Specific enzymatic kits can measure fructose levels by using enzymes that selectively react with fructose to produce a measurable change, typically detected colorimetrically.
4. **Refractometry**: While less specific, a refractometer can give an idea of total soluble solids, which includes sugars like fructose, glucose, and sucrose.
5. **Mass Spectrometry (MS)**: Coupled with chromatography (like LC-MS), this can provide comprehensive information on the types of sugars present, including their quantities.
To provide evidence specifically about peas being high in fructose, studies would typically present quantified results from one or more of these methods. Always refer to peer-reviewed studies for data on specific food items like peas.
