Steaming boilies is better if you want quality water-soluble attractants to stay in the bait.<\/strong> When boiling, betaine, free amino acids, GLM extract, liver extract, soluble peptides and water-soluble vitamins partly pass into the cooking water. When steaming, the boilie doesn\u2019t sit directly in water, so these substances are hardly washed out at all. Boiling still makes sense for cheap base mixes, large amounts of bait and fast production. Steaming pays off above all for premium boilies, hookbaits, pop-ups and boilies with expensive extracts.<\/p>\n\n\n You\u2019ve put expensive ingredients into your boilie paste \u2014 GLM extract, betaine, free amino acids, liver extract. Then you boil the boilies for 90 seconds to a few minutes in hot water. What happens is simple: some of these water-soluble attractants dissolve in the cooking water and don\u2019t all stay in the bait. The cooking water smells fantastic \u2014 because it contains exactly the substances that should be working in the boilie.<\/p>\n\n\n Steaming reduces this problem considerably. No direct contact with water, far less wash-out. The boilie keeps sensitive, water-soluble ingredients inside much better. That\u2019s the core of the difference \u2014 and an important reason why many professional bait companies steam their premium hookbaits, pop-ups and expensive extract blends.<\/p>\n\n\n When boiling, the rolled boilies go into boiling water for around 90 seconds to 3 minutes<\/strong>. The exact time depends on boilie size, recipe, egg content, flours, binders and the hardness you want. The heat denatures the proteins in the paste. Egg protein, fishmeal proteins and plant proteins coagulate, form a firm matrix and turn the soft paste into a stable carp bait.<\/p>\n\n\n At the same time the problem starts: water is a strong solvent. Free amino acids, betaine, extracts, water-soluble vitamins and soluble peptides can pass into the cooking water through the surface, which isn\u2019t fully sealed yet. The more water-soluble ingredients a mix contains, the more this matters. Over time the cooking water turns into an attractant extract itself \u2014 a clear sign that active substances are leaving the bait.<\/p>\n\n\n Betaine is not destroyed by heat during boiling.<\/strong> Betaine, chemically N-trimethylglycine, is thermally stable at boiling temperatures of around 100 \u00b0C. Its zwitterion structure stays intact at this temperature. If betaine is lost during boiling, it\u2019s not through thermal breakdown but through its water solubility and diffusion into the cooking water.<\/p>\n\n\n That\u2019s an important difference: betaine in the cooking water is lost betaine \u2014 but not burnt or destroyed betaine.<\/strong> When steaming, betaine stays in the boilie better because there\u2019s no direct contact with water. That makes steaming particularly interesting for quality mixes with betaine anhydrous: the effect is better preserved not because of a lower temperature, but because less betaine is washed out. How betaine works in a boilie and how to dose it is explained in the article Boilie attractants \u2013 betaine, amino acids and DMPT<\/a>.<\/p>\n\n\n In practice this means: if you use betaine in boilies, you don\u2019t need to fear 100 \u00b0C heat. What matters is whether the boilie sits in water or is only cooked in steam. When boiling, betaine can migrate from the boilie into the water. When steaming, it stays in the bait much better.<\/p>\n\n\n When steaming, boilies aren\u2019t cooked in water but in hot steam. Depending on the equipment, the temperature is about as high as when boiling, but the decisive difference is the lack of direct contact with water. The boilie sits in steam, not in water. Water-soluble substances therefore have no direct route into the cooking water.<\/p>\n\n\n The principle is similar to steaming vegetables: steaming preserves water-soluble components better because they aren\u2019t washed out into the cooking water. Applied to boilies, this means betaine, free amino acids, GLM extract, liver extract, hydrolysates and soluble peptides tend to stay in the boilie better.<\/p>\n\n\n The downside: steaming takes longer. Small boilies can be done after around 8\u201310 minutes, larger or denser boilies need more like 10\u201317 minutes. You also need equipment: a steamer, an electric preserving cooker, a steamer insert or, in professional production, a combi steamer.<\/p>\n\n\nWhat happens when you boil \u2013 the process<\/h2>\n\n\n
