Konjac as a noodle alternative
Konjac is a plant native to Asia that has been used in traditional cuisine for centuries. The root of the konjac plant is high in glucomannan, a type of dietary fibre. Konjac corms are high in fibre but low in carbohydrates, calories, and fat, making them a good noodle alternative for those on a low-carb diet.
Konjac noodles, also known as shirataki noodles, are translucent, grain-free, and low-carb. They come in many forms, from ramen-style to spaghetti-style, and can easily absorb a variety of flavours. Before konjac solidifies, it's passed through thin holes and boiled, creating fine, string-like noodles. The noodles are perfect for dishes like sukiyaki or salads, as well as stir-fries. When using shirataki in stir-fry dishes, dry-fry the noodles beforehand to remove excess moisture, allowing them to better absorb flavours.
Konjac can also be dried and turned into a powdered form, which can be added to baked goods or stews to act as a thickening agent. It can also be mixed with liquids and sweeteners to make a jelly-like dessert.
It is important to note that konjac can pose a choking hazard, especially for children and adults with swallowing disorders, as it swells when mixed with liquids. It is recommended to consume konjac with water to prevent choking.

Konjac flour is a versatile and health-rich ingredient that is growing in popularity. It can be used in baked goods such as bread, cakes, and cookies. When used in bread, it is important to consider the formulation as the percentage of konjac flour can affect the taste and texture of the final product. For example, a 2021 study found that bread with around 37.5% konjac flour had the best formulation, while breads with over 25% konjac flour were less palatable due to a fishy taste.
When baking with konjac flour, it is important to follow recipes specifically designed for konjac as the flour behaves differently from wheat flour. It is also important to consume konjac with plenty of water, as it swells when mixed with liquids, which can pose a choking hazard.
