Production of raisin

The technique of raisin production in India is mostly based on the dipping of the grape bunches in emulsion having 2.5% potassium carbonate and 1.5% ethyl oleate for a duration of 2 to 4 minutes, and subsequent shade drying in open tier system (Adsule et al., 2012). Quality is one of the major concerns in raisin production; hence, extensive research is necessary to find the effect of storage temperature on physico-chemical characteristic of raisins prepared from seedless varieties of grapes.

A study on production and marketing of raisins in Vijayapura district was carried out during 2016-17 with an objective of analysing the viability in production and marketing of raisins. The study indicated that the cost incurred to produce raw grapes (11.90 tons) from an acre of grape orchard was Rs. 2,04,584.49.

A biscuit is a baked, commonly flour-based food product. They are made with baking powder or baking soda as a chemical leavening agent rather than yeast. Biscuit‟s ingredients are wheat flour, sugar, butter or oil, eggs and baking powder. Sometimes other ingredients like fruit pieces, nut, raisins, improver and stabilizer are used. In this present study a novel tea-biscuit was produced by incorporating betel leaf oil as essential oil in the formulation of the biscuit. Essential oils are mainly considered as GRAS materials. So, in this formulation of tea-biscuit 0.025%, 0.05%, 0.075% and 0.

In this study, raisin was produced from pre-treated grapes by tray drying method. Grapes were cleaned and soaked in a different type of solutions such as potassium carbonate, olive oil, soy lecithin, and sugar concentration for different immersion time. The pre-treated grapes were then dried in a hot air tray drier at 50°C and airflow 1.0 m/s. Results showed that drying time was varied for pre-treated grapes. The shortest drying time of 61 h) was obtained for those grapes which were dipped in 6.7 % potassium carbonate solution for immersion time of 5 min.

Grapes are good source of dietary sugars, organic acids and provide good amount of minerals like iron and phosphorus and some vitamins. Among the grape processed products raisins are one of the most important processed products obtained from grapes. The mature, clean and uniform size green grape berries (Thompson seedless) were taken. The berries were treated by using different methods viz. Preyal dip, Australian dip and soda dip. Drying was done at 50 and 60oC to study the effect of drying temperature on quality of raisin. The grape berries were dried from 78 per cent (345.54 per cent, d.
