Tomato paste is a processed food product that as a tomato extract contains a large number of tomato properties that are used as a seasoning in most foods due to the pleasant color, taste and smell for a variety of meat and fried foods. In the industry, tomato paste is used to prepare various types of tomato ketchup and food condiments. In the not-so-distant past, everyone used to cook their own paste traditionally at home. But today, technology has come to the aid of human beings so that tomato paste can be easily available to everyone in the healthiest conditions, the highest packaging and finally the quality.
Tomato puree is a watery food that is used in cooking. To make the puree, the tomatoes are completely raw or smoothed after heating, after which they turn into juice and then into a concentrated concentrate. The less salt is used when concentrating, the better the fresh tomato concentrate. When concentrating, the air inside the puree is completely absorbed. Because the main smell and taste of tomato is not lost in the tomato sauce, it is used in tomato sauce, stew sauce, stew and other types of foods with tomato flavor. It is also used as a raw material in ketchup.
How to Preserve Fresh Tomato Concentrate?
Tomato concentrate is produced in different ways. The storage conditions of the concentrate should be such that air does not penetrate into its packaging.
In the preparation of tomato paste, its pulp, which is the same fiber found in tomatoes; Is thrown away. By doing so, part of its properties are actually lost.
But it is a few years; A product called tomato concentrate has been produced and marketed.
Concentrate can be stored easily, in a small space and for a long time. After producing the concentrate, it should be packed in standard and sterile sanitary containers. The packaging must be such that air can not penetrate into the container in any way. In this way, the concentrate can be stored for a long time without the use of preservatives. preserving of fresh tomato concentrate in a cool environment.
Process of Making Fresh Tomato Concentrate
We study the possibility of producing protein concentrate from tomato waste. fresh tomato concentrates nutritional value .For this purpose, after identifying the chemical composition of different parts of tomato processing waste, including complete waste (containing skin, seeds and mucilage), oiled seeds and seeds, protein concentrates were prepared by alkaline dissolution and acid precipitation. To select the most suitable extraction conditions and achieve maximum efficiency, in the alkaline phase of pH 8, 9, 10, 11 and 12 and temperatures of 20, 30, 40, 50, 60 and 70 ° C, and in the acidic precipitation phase of pH 3.3 , 3.5, 3.7, 3.9, 4.1, 4.3, 4.5, 4.7, 4.9, 5.1, 5.3 and 5.5 were used. After determining the protein concentration and volume of supernatant in the alkaline dissolution stage, the best conditions were estimated to be pH = 12 and ambient temperature (25-27 ° C) and the maximum efficiency in the acid precipitation stage for the total pulp protein concentrate at = 3.9, respectively. pH was obtained for seed protein concentrate and oiled seeds at pH = 4.1. In order to investigate the effect of thermal process in the isoelectric precipitation stage on the extraction efficiency and its functional properties including water absorption capacity and oil absorption capacity, temperatures of 25-100 ° C were used. According to the results, the highest amount of sediment is obtained at high temperatures and the highest percentage of sediment protein is obtained for whole pulp protein concentrate and seed protein concentrate at ambient temperature and for oily seed protein concentrate at 70-85 ° C. Come on. The water absorption capacity of protein concentrates also increases at higher temperatures. On the other hand, with increasing the extraction temperature, the average oil absorption capacity of the samples increases significantly.
