Cereal Prawn Calories Singapore: Per Plate and Per Scoop, in Grams

By the NutriKaki Team · Data from HPB Singapore · Published October 2026

Short answer: using HPB food data, one plate of cereal prawn (319 g) has about 750 kcal, and one 100 g serving-spoon scoop has about 235 kcal. The plate carries 50.5 g fat and 940 mg sodium.

Cereal prawn is a zi char dish of prawns coated in a toasted oat-cereal mix. Here are its numbers in grams, with the portion size next to every figure.

Cereal Prawn Nutrition: Per 100 g, Per Scoop and Per Plate

HPB lists cereal prawn (also known as oat prawn, mai pian xia or zhu chao) at 351 kcal per 100 g, with 15.7 g protein, 23.65 g fat, 18.92 g carbohydrate, 2.1 g sugar and 440 mg sodium per 100 g. HPB also records that only 67% of the weight is edible, because of prawn shells and heads. Every serving figure below applies that 67%.

Cereal prawn portion	Calories	Protein	Fat	Carbs	Sugar	Sodium
Per 100 g, as weighed	351 kcal	15.7 g	23.65 g	18.92 g	2.1 g	440 mg
1 serving-spoon scoop, 100 g (HPB default portion)	235 kcal	10.5 g	15.8 g	12.7 g	1.4 g	295 mg
1 plate, 319 g (HPB plate size)	750 kcal	33.6 g	50.5 g	40.4 g	4.5 g	940 mg

How the plate figure works: 319 g x 67% edible is about 214 g of edible food, and 351 kcal per 100 g x 2.14 gives about 750 kcal. Sharing a plate between two people means each person has about 160 g of the plate, which is about 375 kcal (half of the 319 g plate figure).

Cereal Prawn vs Other Zi Char Prawn Dishes

All figures use HPB food data and the portion shown in each row. Scoops are HPB's default serving-spoon portion for that dish; plates are HPB's recorded plate size.

Dish and portion	Calories	Protein	Fat	Carbs	Sugar	Sodium
Cereal prawn, 1 serving-spoon scoop (100 g, HPB default)	235 kcal	10.5 g	15.8 g	12.7 g	1.4 g	295 mg
Cereal prawn, 1 plate (319 g, HPB plate size)	750 kcal	33.6 g	50.5 g	40.4 g	4.5 g	940 mg
Sambal prawns, 1 serving-spoon scoop (100 g, HPB default)	105 kcal	7.9 g	6.5 g	3.6 g	3.3 g	428 mg
Sambal prawns, 1 plate (356 g, HPB plate size)	372 kcal	28.1 g	23.2 g	12.8 g	11.7 g	1525 mg
Assam prawn, 1 serving-spoon scoop (122 g, HPB default)	134 kcal	19.5 g	4.7 g	3.3 g	2.6 g	882 mg
Sweet and sour prawn, 1 serving-spoon scoop (100 g, HPB default)	156 kcal	7.4 g	8.1 g	13.3 g	7.5 g	80 mg

On a plate basis, the 319 g cereal prawn plate has about 750 kcal against about 372 kcal for a 356 g plate of sambal prawns. The gap comes mostly from fat: 50.5 g in the cereal prawn plate against 23.2 g in the sambal prawns plate. The sambal prawns plate has more sodium (1,525 mg against 940 mg) because HPB lists sambal prawns at 500 mg per 100 g and the plate is larger.

Read the portion first: a "scoop" and a "plate" differ by 219 g. When comparing cereal prawn with any other dish, check that both numbers use the same gram portion.

Frequently Asked Questions

How many calories are in a plate of cereal prawn?

HPB food data records a plate of cereal prawn (zi char) at 319 g. After HPB's 67% edible portion, that plate has about 750 kcal, 33.6 g protein, 50.5 g fat, 40.4 g carbohydrate, 4.5 g sugar and 940 mg sodium.

How many calories are in one serving-spoon scoop of cereal prawn?

Why is the per-100 g figure (351 kcal) higher than the per-scoop figure (235 kcal)?

HPB's per-100 g figure of 351 kcal is for the food as weighed, and HPB records only 67% of cereal prawn as edible. A 100 g scoop therefore counts as 67 g edible, which is 351 x 100/100 x 67/100 = 235 kcal.
