Starch sugar is very competitive

Jan 10, 2012   //   by   //   Artikel English  //  No Comments

Recently brewers had eyes for starch sugar as a technically and economically attractive raw material for beer, and many will switch to locally produced starch sugar.

Beet and cane sugar and molasses have traditionally been used as the preferred carbohydrate source in fermentation processes, because it is cheap and abundant available. This is still the case, but starchy crops are cultivated just as economically and feasible as cane and beet. Thus, High Fructose Syrup based on corn has in the United States demonstrated an explosive growth and largely supplanted cane sugar for industrial applications. To replace the traditional sugar and molasses as carbohydrate source in fermentation all needed is a starch and glucose front end to be added to the fermentation plant.

A starch front end enables the manufacturer to take advantage of starch crops as a cheap and reliable carbohydrate source.

Many products compete for molasses – biofuel in particular. Not only the sugar (sucrose), but also corn has recently become part of a biofuel economy. This may be the reason behind a new trend towards the use of cassava, which can be grown and harvested in the tropical belt round the year a big advantage.

Production based on carbohydrate fermentation will for this reason gradually migrate to tropical or subtropical areas with cheap sources of carbohydrates.

  1. PENDAHULUANSerealia dan umbi-umbian banyak tumbuh di Indonesia. Produksi serealia terutama beras sebagai bahan pangan pokok dan umbi-umbian cukup tinggi. Begitu pula dengan bertambahnya penduduk, kebutuhan akan serealia dan umbi-umbian sebagai sumber energi pun terus meningkat. Tanaman dengan kadar karbohidrat tinggi seperti halnya serealia dan umbi-umbian pada umumnya tahan terhadap suhu tinggi. Serealia dan umbi-umbian sering dihidangkan dalam bentuk segar, rebusan atau kukusan, hal ini tergantung dari selera.Usaha penganekaragaman pangan sangat penting artinya sebagai usaha untuk mengatasi masalah ketergantungan pada satu bahan pangan pokok saja. Misalnya dengan mengolah serealia dan umbi-umbian menjadi berbagai bentuk awetan yang mempunyai rasa khas dan tahan lama disimpan. Bentuk olahan tersebut berupa tepung, gaplek, tapai, keripik dan lainya. Hal ini sesuai dengan program pemerintah khususnya dalam mengatasi masalah kebutuhan bahan pangan, terutama non-beras. Ubi kayu atau singkong (manihot ) merupakan salah satu bahan makanan sumber karbohidrat (sumber energi).
    Tabel 1. Komposisi Ubi Kayu (per 100 gram bahan)
    Kalori 146,00 kal
    Air 62,50 gram
    Phosphor 40,00 mg
    Karbohidrat 34,00 gram
    Kalsium 33,00 mg
    Vitamin C 30,00 mg
    Protein 1,20 gram
    Besi 0,70 mg
    Lemak 0,30 gram
    Vitamin B1 0,06 mg
    Berat dapat dimakan 75,00

    Ubi kayu dalam keadaan segar tidak tahan lama. Untuk pemasaran yang memerlukan waktu lama, ubi kayu harus diolah dulu menjadi bentuk lain yang lebih awet, seperti gaplek, tapioka (tepung singkong), tapai, peuyeum, keripik singkong dan lain-lain. Read more >>

Starch … a renewable raw material

Oct 27, 2011   //   by   //   Artikel English, Tapioka  //  1 Comment

Starch is abundant. All major agricultural crops contain starch. Colder climates favour potato growing, the tropics cassava, while grain varieties are grown all over the world. With sun and water as the main limitations, fifteen tons of starch dry mater can be achieved per hectare.

Modern techniques enable starch to be extracted from agricultural crops with high yield and extreme purity, making starch the most versatile raw material used within the food and chemical industries. The starch granule is a compact package of pure glucose polymer.

The purity and efficient moisture absorbing properties of starch have made it indispensable in the production of medicinal tablets and as a moisture regulator.

Polymer releases from the granule during cooking. At 60 oC, the polymer begins to hydrate, adding its viscosity and gelling power to the water. This is the way puddings are made in the home – just by using native starch. The food industry also employs native starch as a binder and thickening agent in snacks, meat products, sausages, etc.

Although native starch does have its industrial uses, most often industry requires the functionality of modified starch. The modification is achieved in one of two ways – either by the starch producer, who modifies the starch without disrupting the granules, or by the end-user who cooks and modifies the starch in a single step operation. The first method results in a granular product good for storage and the other in a ready-to-use paste. The two methods do not always act as a substitute for the other.

The single largest consumer of modified starch is the paper industry.

Starches are used as wet-end additives, as size press starches, as binders in coatings and as adhesives. Cationic starches provide retention at the wet-end and reduce the amount of pollutants released. Oxidised starch is a good film-forming product – a favoured material for coating and surface sizing. Thin boiling starches produced by acid or enzyme treatment are used as well.

Special starch produced by esterification or combined treatments are used in coatings, glues, the production of cardboard, etc.

The Stein Hall process of manufacturing corrugated cardboard employs both cooked and uncooked starch. Cooked starch adds viscosity while uncooked starch swells up as the cardboard liner passes the heating rolls, giving instant bond. Pre-swollen starch is used alone in no-carrier adhesives.

The process of drilling for oil uses starch in the suspension of excavated mud. During this process, starch is either employed alone or in combination with other stabilisers, e.g. xanthan gum. Within the textile industry, thin boiling starch has made a comeback in the competition with petrochemicals.

The addition of chemical groups to the starch chain improves the clarity and stability of the gel during cooking, mixing and freezing. These chemicals include propylene oxide, acetic acid, and metaphosphates. They form tailor-made hydrocolloids, which go into desserts, ice cream, puddings, wine gums, etc.

Starch is the cheap and reliable source of energy for the biochemical manufacturing of alcohol, enzymes and fine chemicals. When broken down by enzymes or acids it becomes the basic ingredient for producing glucose, fructose and sorbitol.

Tapioca flour and exports growth areas

cassava balance sheetThe Thai tapioca industry will focus on flour exports and Asian markets as part of its growth strategy over the next five years, when the exports of tapioca products could reach 100 billion baht.

The Commerce Ministry projected that by 2016, domestic demand for cassava roots in ethanol production will surge to 13 million tonnes, while exports could top 22.5 million tonnes, totalling 35.5 million tonnes, up 42% from the current production levels.

Speaking at the World Tapioca Conference 2011, Yanyong Phuangrach, the ministry’s permanent secretary, said Thailand should focus more on exporting tapioca flour to substitute for a reduction in the export of tapioca chips and pellets.

The proportion of flour exports is expected to rise to 65% from 51% now, with chips and pellets making up the rest.

Mr Yanyong said the country should build a good image and accept the standards of its tapioca flour and other products to create confidence among importers, buyers and local consumers. Read more >>

kecap dari limbah tapiokaUbi Kayu (Manihot utilissima Phol) merupakan bahan makanan yang sangat potensial yaitu sebagai bahan baku industri pangan melalui pengolahannya menjadi tepung tapioka. Pemanfaatan umbi kayu telah lama dikembangkan di Indonesia yaitu dengan mengolahnya menjadi berbagai bentuk baik sebagai bahan baku atau bahan setengah jadi maupun dalam bentuk pangan olahan seperti: dibuat tepung tapioca, cake, tape, sirup glukosa, pudding dan lain-lain. Sebagai salah satu jenis umbi-umbian maka ubi kayu merupakan salah satu sumber karbohidrat karena kandungan karbohidrat ubi kayu sangat tinggi yaitu 34,7 gr per 100 gr bahan. Selain mengandung karbohidrat yang tinggi, ubi kayu juga mengandung kalori sebesar 148,0 kal dan mineral-mineral penting seperti calsium (Ca) 33,0 mg, Phospor (P) 40,0 mg serta kandungan vitamin C yang cukup tinggi 30,0 mg.
