Introduction

Biscuits look simple, but taste and crispness depend a lot on the ingredients you use and how you handle them. Here are the main raw materials for biscuit manufacturing, what each one does, and how to store and handle it well.

MAIN RAW MATERIALS FOR BISCUIT MANUFACTURING

Three materials make up most of a biscuit, as food technology course notes explain: wheat flour, sugar and fat.

1. Wheat flour (maida)

Flour gives bulk and structure. Biscuits normally use soft wheat flour with weaker gluten, not strong bread flour, otherwise the dough turns tough. Protein and moisture limits depend on your biscuit type.

2. Sugar

Sugar gives sweetness, colour and bite. Granulation is very important: coarse sugar can leave grit, so many plants grind it. Cream fillings need much finer sugar (around 200 mesh) than normal dough, as we explain in Universal Mill vs Air Classifier Mill.

3. Fat

Fat, such as vegetable fat, shortening or butter, makes biscuits short and tender. Its temperature affects mixing and dosing, so it must be controlled.

OTHER INGREDIENTS USED IN SMALL QUANTITY

  • Milk powder: adds taste and colour.
  • Salt: improves flavour and brings out sweetness.
  • Leavening agents such as baking soda and ammonium bicarbonate: make biscuits light.
  • Lecithin and egg powder: help binding and emulsifying.
  • Flavours and syrups: add taste and spread control.

The quantities are small, but errors here show up quickly in taste and texture, so weigh them accurately.

QUALITY CHECKS WHEN MATERIAL ARRIVES

  • Check the supplier certificate and batch number.
  • Test flour for moisture and protein, and look for insects or foreign matter.
  • Check sugar for lumps, moisture and colour.
  • Check fat for temperature and smell.
  • Store with first-in-first-out, and keep records for audits.

HANDLING PROBLEMS IN RAW MATERIALS FOR BISCUIT MANUFACTURING

  • Dust and spillage: use enclosed pneumatic transfer and a dust collector. Flour and sugar dust can be combustible, see OSHA guidance.
  • Sugar caking: keep ground sugar in dry, closed storage.
  • Uneven fat dosing: use a liquid handling system with temperature control and flow metering.
  • Manual weighing errors: use load-cell weigh hoppers with PLC. See our raw material handling system.

Frequently Asked Questions

Wheat flour, sugar and fat are the three main ones. Milk powder, salt, leavening agents, lecithin and flavours are used in small quantities.

Soft wheat flour (maida) with weaker gluten is generally preferred, because strong bread flour makes dough tough. Exact limits depend on your biscuit type.

Finer sugar mixes better and gives a smooth bite. For cream fillings, fine sugar around 200 mesh avoids a gritty feel.

Keep it in closed, dry storage such as a food-grade silo or sealed bins, use first-in-first-out, and sieve with a magnet before it goes to the mixer.

Fat that is too hot or too cold doses unevenly and changes the feel of the dough.
