Ice cream Essay

The Philippines is a tropical country where temperature is high especially during summer hence Filipinos find ways to counter the uncomfortably sweltering weather especially during the summer months when ambient temperature reaches 43oC. They eat frozen food and desserts including ice cream. Ice cream is a frozen dessert made from dairy products such as milk and cream combined with flavorings and sweeteners . In some cases, artificial flavorings and colorings are added instead of natural ingredients. (Moreno, 2015).

The ice cream industry in the Philippines is composed of only a few ice cream companies who supply ice cream and dairy products in the country. The proliferation of smaller companies offering-low price branded products in the market has been snatching sales from major brands of ice cream resulting to Philippine government to implement ice cream regulation, the FDA has regulations regarding ice cream so that consumers know exactly the nutritional facts of this well-loved dessert.

Artisanal ice cream roughly translates to “dirty ice cream” produce by using traditional ice cream preparation in small batches and using manual method. The artisanal ice cream uses several common tropical fruit flavors such as mango, avocado, young and young coconut shavings. Nuts, cheese and chocolates chips and cookies are also normally added to add flavour to ice cream. The dominant market segment for ice cream is normally children, however, adults and young adults also relish eating the product (Muelhoff, 2013). It is therefore important that the nutritional component of ice cream be fortified to make it a healthier product fit for consumption of children. Ice cream can be fortified in a number of ways such as addition of healthy vegetables like squash.

Squash (Cucurbita maxima), is a vegetable crop cultivated since ancient times . It is a marginalized crop in terms of cultivation, marketing, industrialization and research. There are few scientific studies on its physical, chemical, physicochemical, nutrimental, functional and technological characteristics. Some scientific literature on squash highlights its importance as a source of α and β-carotene, lutein, vitamin C, dietary fiber, minerals, and phenolic compounds. These nutrimental and bioactive components are very important in providing human health benefits. Different researchers agree in indicating that more scientific studies are needed to achieve greater and better utilization of this important crop.( Noelia et al.",2011)

Squash has a very rich natural profile that consists of various organic compounds, nutrients, vitamins and minerals, which are responsible for providing all its impressive health benefits. This list includes a huge amount of vitamin A, as well as significant amount of vitamin C, vitamin E, vitamin B6, niacin, thiamin, pantothenic acid and folate. In terms of minerals, squash contains magnesium, potassium, manganese, copper, phosphorous, calcium and iron. It is also a very good source of carotenoids and other important anti-inflammatory and antioxidant compounds. (Lopez-anido et al., 2013).

Several processed food products using squash as the raw material have been developed by a number of research agencies in the Philippines notable in which is the Food and Nutrition Research Institute (FNRI), one of the country’s leading government research institutions under the Department of Science and Technology (DOST). Examples of these processed products include squash flour, squash juice, squash catsup, squash vinegar, squash noodles, squash chips, squash polvoron and squash pastillas. (Department of Agriculture 2011)

In addition, various kitchen recipes were supplemented with either squash flour, freshly grated squash or mashed squash are squash “leche flan, squash “halaya”, squash “macaroons”, squash “halaya”, squash “suman” and squash “kutsinta”. (Pinoy Recipes 2015).

The squash as an available resource beyond the backyard can be utilized to potentially enhance the appearance, aroma, texture and taste of ice cream as well provide nutrients. It is the intention of the researcher to use accessible and nutritious resources to develop and improve the regular artisanal ice cream recipes by further adding tropical fruit flavour to the squash-based ice cream.


The principal objective of the study is to develop squash-based “nutritious” artisanal ice cream flavored with mango. The following are the specific objectives:

1. To determine the acceptability of artisanal squash-based, mango-flavored ice cream in terms of appearance, color, aroma, taste and texture using various proportions of squash in the formulation;

2. Describe the the physico-chemical characteristics of the squash-flavored ice cream ; and

3. Assess whether the quality of the squash-based ice cream differs if four various formulations will be used.

Materials and Methods

This is an experimental study using the input-process-output model shown in Figure 1 in the formulation and evaluation of the most acceptable “nutritious” artisanal squash based ice cream with tropical fruit flavour.

Phases of the Study

There are two phases in the study namely: 1. Determination of the most acceptable level of squash in the formulation as flavor on artisanal ice cream and 2. Determination of the most preferred tropical fruit combined in artisanal squash based ice cream in the three variants namely: “Mango”, “Pineapple”, and “Passion Fruit”. The flow chart of the study is shown in figure 2.

Phase 1. Determination of the most acceptable level of squash in the formulation of artisanal nutritious squash based ice cream

The initial experiment was to determine the most acceptable level of squash powder in squash based ice cream. The proportions of the experimental lots will be 150g, 200g , 250g and 300g squash powder. A standard formulation as provided in Table 3 for plain ice cream will be used as basis in the preparation of the squash-based ice cream.
