"Wow, dude, why do you have so many bobber adjustment buckets? This setup is more advanced than what's in my fishing gear store! You've got five buckets!" Zhang Yang couldn't hold back his curiosity and asked.
"I collected bobber parameters a few days ago, bought more at once for convenience during experiments! These are for my new project on studying bait conditions, haven't finished handling them yet!" Yu Dong replied casually.
"Studying bait conditions?" Zhang Yang followed up on the topic.
"Exactly! Even though the water ratio is the same and the materials are similar, once the bait is prepared, the condition varies greatly, and some backwash severely! I'm curious about the reasons!"
"Oh, there's no need to study it, I know the reason! The bait ingredients contain starch, which decomposes to sugar and produces moisture. When bait sugarifies, its water absorption rate changes too, releasing more water!"
Zhang Yang answered naturally, as he viewed it as common knowledge.
"Starch turning into sugar? Fermentation?" Hearing this explanation, Yu Dong paused, seeming to ponder the accuracy of the answer.
Zhang Yang elaborated, supplementing his previous explanation: "It's not entirely due to fermentation. Backwash is actually a systemic issue where the ingredients in the formula reach a balance once when preparing the bait, some substances change over time, altering the water absorption capacity, these are roughly the two aspects!"
"I get it! You also research fish bait?" Yu Dong nodded, acknowledging Zhang Yang's explanation.
"Just a little, can't compare with professional aquaculture guys like you!"
"No wonder you can mix and match to make that kind of black syrup small additive, turns out you're into research too!" Yu Dong continued.
Mentioning black syrup, Zhang Yang, upon hearing the use of the term 'mix and match', thought he could use this opportunity to explore the topic further.
To win over an expert, besides using money, other options include sharing knowledge unknown to them or gaining identity recognition.
Since this dude is the typical engineering type, Zhang Yang decided to show off a bit more to up the stakes.
"Since you mentioned black syrup, let me tell you! Actually, the formula you published on the forum is heading in the wrong direction!
The black syrup I have is produced by brewing black sugar, red dates, and hawthorn, not by mixing flavors!
While food flavoring can blend taste, composition-wise, what you've made is vastly different from what I sell!"
"What? You brew it? How can that be! I've experimented many times and couldn't achieve the finished product's condition!" Hearing these words, Yu Dong was stunned, eyes full of disbelief.
His initial direction was indeed brewing, but after exhaustive trials, he never managed to reach the taste and state of Zhang Yang's standard product, so he thought Zhang Yang used food flavoring! He didn't expect this path was wrong.
Zhang Yang grinned, "Why is it impossible! You just haven't found the method!
To make a black syrup with stable quality, control of heat and material handling require specific standards, it's not just about randomly boiling in a big pot and cooling it down to use!
Brewed sugar for too long will burn, making the taste bitter, improper handling of dates and hawthorn will leave residues tainting the base liquid, poor heat control leads to excess moisture, resulting in bacterial fermentation, producing gas and sourness!
Many details can't be resolved with just a few blind tries!"
Yu Dong encountered these issues repeatedly in his experiments.
An expert can be recognized just by a few words, Zhang Yang's casual chatting already thoroughly impressed Yu Dong!
