DSFT provides a range of consultancy services to ice cream, gelato, sherbet and sorbet manufacturers. These range from help in formulating recipes, reducing costs by replacing expensive imported additives, problem solving, courses in advanced product manufacture, advice on all aspects of HACCP including process validation, providing assistance in discussions with regulatory authorities to independent audits of plant, process and external advice received. Independent nutritional advice on the manufacture and safety of low or sugar-free gelato and ice cream products is also provided.
We can help with the development and commercial production of soya and dairy-free, high protein ice cream-like products with or without sucrose. There are better options than sorbitol and fructose. Science based advice on describing products intended for consumers with health issues can also be provided.
Despite work undertaken over 20-years ago by researchers in Canada many large scale ice cream producers have limited knowledge of the minimum holding time of ice cream mix processed using HTST or HHST heat-processes. Furthermore many lack the evidence that they meet regulatory requirements for holding time. DFST can use your plant data to calculate average holding time, flow type, minimum residence or holding time, the log reductions of major pathogens and advise on any remedial action required.
There are no restrictions on users modifying or customising spreadsheets and some packs contain customised spreadsheets for the most commonly used ingredients e.g. cream, whole milk and skim milk powder. One of the simpler spreadsheets (Pack 2) has been converted to a web page to illustrate how this can be done. Batch sizes can be calculated and "costed", data inputs can easily be validated and alerts can be added e.g. if the MSNF is not optimal or within certain limits or if the fat: sugar ratio exceeds set limits.
To reduce costs some manufactures are using vegetable fat / milk fat blends. One of the spreadsheets in Pack 6 enables the quantities of milk fat and vegetable fat required to produce a mix to a desired dairy and vegetable fat ice cream recipe to be calculated. Alerts can also be added if the % vegetable fat exceed a set limit e.g. 40% w/w of the total fat or if the milk fat falls below 60% of the total fat.

This section is aimed at product development technologists who need to know how to design ice cream mixes. It should also be of interest to small scale ice cream or gelato manufacturers who want to replace commercial ice cream mixes (bought in mixes) or additives by sourcing their own ingredients and additives. The article provides a basic introduction to the scientific principles involved in producing ice cream or gelato recipes using key product components e.g. fat.

Ice cream and gelato manufacturers produce products with a range of favours. There are often significant variations in sweetness and hardness between flavours. This article provides an explanation of sweetness, how it is measured and how it can be controlled.
Relative sweetness and the Potere Dolcificante method are discussed and calculations are used to explain the differences. The limitations and disadvantages of using numerical values of sweetness are explained. Since sweetness and hardness are closely related the reader is also referred to the article on controlling hardness or resistance to scooping.
In this article we will explore how to use mix composition to control the hardness or "scoopability" of ice cream. The serving temperature which influences the concentration of ice present will also be considered. The volume of air added during freezing (overrun) and the concentration of emulsifier can also affect hardness. However, these effects are generally less significant than the concentration of sweeteners used and serving temperature. This article should be read in conjunction with the article on the sweetness of ice cream.

So you want to start an ice cream and Gelato shop business?
The purpose of this article is to help anyone interested in starting their own ice cream business to get started. I am an artisan ice cream maker with extensive experience of industrial scale ice cream making. While I will discuss both artisanal or traditional and industrial or large scale ice cream manufacture, the main emphasis will be on artisanal production.
In Northern Europe and North America there is relatively little use made of whole milk powder (WMP) in commercial ice cream manufacture. However small scale ice cream or gelato manufacturers sometimes use these ingredients. In Vietnam and other Asian countries ice cream is frequently made from whole milk powder and cream.
Small, and even large companies, frequently find it difficult to contact potential new supplier partners. This is a particular problem for some small companies attempting to get their new business started or wishing to expand.
However there are companies who provide exemplary customer service and work hard to meet customer needs. The following is a list of these companies that provide exemplary customer service in the ice cream sector.
