Coverage of ice cream on this site is limited mainly to ice cream mix formulation, a fairly specialised topic, and generally mainly of interest to people interested in product development.
 
There are big differences between commercial ice cream manufacture and home or hobby ice cream making. Consequently expect differences in texture, melting properties and storage life between commercial and home produced ice cream.
 
Professor Doug Goff from the University of Guelf has an excellent website that describes the commercial manufacture of ice cream and outlines relevant science including the relationship between microstructure, production methods and functional properties.
 
If you produce ice cream for home use  without using emulsifiers and stabilisers, adequate mixing, homogenisation, heat treatment, ageing there are likely to be some quality issues with your product and it is unlikely that this is the best place for you to post queries. A hobby site would probably be better.
 
Forum users with queries on textural, storage and fast melting ice cream problems may find the following references useful:

most stabilisers used in ice cream contain carageenan but there is a link of carageenan to cancer. Is this true? if it is true what other stabiliser can be used in its place without affecting the functional properties?

Sorry for the delay in responding, not in the UK at present. There are basically two types of carageenan, the undegraded type used in ice cream and in foods has been found to be safe. I am aware of no concerns regarding consuming carageenan approved for use in food. I will give some references to safety when I return home.
Degraded carageenan on the contray my cause colon inflammation, this could ultimately lead to cancer.
