Cream of Chestnut Soup: the freezing questions
What is the freezer window for cream of chestnut soup before it goes off?
Cream of chestnut soup holds about 2–3 months, cream of chestnut soup should tire, treat it as sound frozen. Serve cream of chestnut soup soon, gauge it on taste, label it with the day. Eat cream of chestnut soup soon, store it below 40 °F, count it as safe.
Can cream of chestnut soup handle two trips through the freezer without risk?
Return cream of chestnut soup once cooked, stow it in the cold, heat it through first. Leave cream of chestnut soup in the cold, size it into lots, refreeze it a second time.
How do the cream in cream of chestnut soup hold up in the freezer?
Fold cream of chestnut soup into a stew, score cream of chestnut soup on taste, use it soon. Set aside the cream to serve, keep it chilled, tag cream of chestnut soup by month. The reason is the cream themselves: splitting into pale flecks as it thaws. Freeze the base without it and stir a fresh splash in as it reheats.
The details that decide it
A pulsed magnetic field is what keeps the chestnut in a frozen soup from crumbling
The chestnut is the food this soup is built on, and a chestnut is mostly water held in a starchy tissue, so how the ice is allowed to form decides whether the puree stays smooth or turns grainy. This study froze fresh chestnuts four ways: a conventional cabinet at minus twenty, a rapid freezer at minus forty-five, the same rapid freezer with a three millitesla two-dimensional pulsed magnetic field laid over it, and an ultra-low cabinet at minus eighty. The pulsed-field chestnuts crossed the phase transition in about four minutes and thirty-three seconds, an eighty per cent saving on the minus twenty control, which is the window in which the ice crystals actually set. The payoff was structural: hardness in that group read 99.36 newtons and fracturability 50.87 newtons, the firmest of the four arms and 73.6 per cent harder than the conventional one, with roughly 89 per cent of the water sitting in the immobile pool. The starch moved as well, its total content falling about ten per cent against the control, its water absorption capacity reaching 1.2 grams per gram, about twenty per cent above the other arms, and its relative crystallinity reading 31.90 per cent against 31.47 per cent.
- Four freezing arms: minus twenty, rapid minus forty-five, pulsed field, minus eighty.
- The pulsed-field arm crossed the phase transition in four minutes thirty-three seconds.
- Its hardness read 99.36 newtons, 73.6 per cent above the conventional arm.
A colder still-air freeze costs the chestnut more juice and vitamin C than a warmer nitrogen spray
A chestnut soup is frozen to be kept for months, and the chestnut in it behaves like the fresh kernel it came from. This study set still air at minus twenty and minus forty against a liquid nitrogen spray at minus forty, minus sixty, minus eighty and minus one hundred, on kernels that had been pre-cooled at four degrees for twelve hours and vacuum-packed six to a bag. Ambient temperature turned out not to be the lever. At the same minus forty, the spray cut the juice lost on thawing by 30.81 per cent against still air, and going a further twenty degrees down to minus one hundred cut the loss another 51.37 per cent below the minus eighty arm, with total weight loss across every arm held between 0.12 and 0.52 per cent. The vitamin C each kernel kept climbed ten per cent from minus forty to minus sixty and eleven per cent again from minus sixty to minus eighty, then only three per cent more at minus one hundred, so the last twenty degrees bought very little. The browning enzymes followed the same curve: at minus eighty the residual polyphenol oxidase and peroxidase activity had fallen 80 and 32 per cent against the slowest arm, and the hardness change across the treatments ran from 41 to 80 per cent.
- Kernels pre-cooled twelve hours and vacuum-packed six to a bag before freezing.
- Nitrogen spray at minus forty cut thaw drip 30.81 per cent against still air.
- From minus eighty to minus one hundred drip fell another 51.37 per cent.
The starch in the puree bleeds water as it is cycled, and a mushroom polysaccharide slows the bleed
A cream of chestnut soup thickens on the chestnut starch, and a starch paste that has been frozen and thawed separates into a watery layer and a stiff one. This study made a paste from the starch of Castanea henryi, the Chinese chestnut, and put it through freeze-thaw cycles of twenty-two hours at minus twenty followed by two hours at twenty-five degrees, three times and ten times, with and without Tremella fuciformis polysaccharide blended in at three parts in ten. After seventy hours of standing the untreated paste had let 65 per cent of its water separate, falling to 60 per cent after three cycles and 58 per cent after ten, while the polysaccharide held the ten-cycle sample to 52.27 per cent. The granules themselves came apart over the same span, the average particle size dropping sharply and the structure of many granules breaking down entirely by the tenth cycle. The gel also softened: its consistency index fell from 2.33 in the fresh starch to 2.15 after ten cycles, with the flow index steady near 0.42 in every sample. Bound water stayed dominant throughout, above 97 per cent and reaching 99.04 per cent in the ten-cycle polysaccharide sample, which is why the free water is what leaves first.
- Cycles ran twenty-two hours frozen, two hours warm, three or ten times over.
- Separated water read 65 per cent fresh, 60 after three cycles, 58 after ten.
- With the polysaccharide the ten-cycle paste separated only 52.27 per cent.
